B. How the Heater Operates
Modulating Condensing Technology is an intelligent system
that delivers highly efficient water heating, maximizing
efficiency by measuring the data parameters of your water
heating system. Some of its features are:
Stainless Steel Water Storage Tank
The stainless steel water storage tank has a combustion
chamber submerged into the tank water. When the water heater
is fired, combustion gases heat the combustion chamber walls,
transferring heat directly into the surrounding water. These hot
gases are blown into secondary heat exchanger coils, where
more heat from these gases is transferred into the water.
Modulating Combustion System
The control monitors the water heating system and
temperatures, regulating burner output during operation to
match system demand. This increase in efficiency allows for
substantial fuel savings.
Gas Valve
The gas valve senses suction from the blower, allowing gas to
flow only if the gas valve is energized and combustion air is
flowing.
Upper Outlet Tank Sensor
This sensor monitors the upper portion water temperature
(outlet) of the water heater. The control module adjusts burner
firing rate so the outlet water temperature meets the set point.
Lower Inlet Tank Sensor
This sensor monitors the lower portion water temperature (inlet)
of the water heater. The control module reduces or increases
input, depending on how close the inlet water temperature is to
the outlet water temperature set point.
Control
The integrated control system monitors upper and lower water
temperature and adjusts fan speed to regulate the heater’s
energy output. This allows the unit to deliver the required
amount of heated energy and nothing more.
Burner
Constructed of high grade stainless steel, the burner uses premixed air and gas and provides a wide range of firing rates.
Condensate Drain System
This is a condensing high efficiency water heater with a
condensate removal system. Condensate is nothing more than
water vapor derived from combustion products, similar to that
of an automobile when it is initially started. It is very important
that the condensate line slopes away from the water heater and
down to a suitable inside drain.
If the condensate outlet on the heater is lower than the drain, us
LP-179 Rev. 4.8.16
a condensate removal pump (Part # 554200, available from
HTP). In addition, local authorities may require an additional
condensate neutralizer to neutralize the condensate.
Condensate neutralizers are made up of lime crystals, marble,
or phosphate chips. Neutralizers can be installed in the field
by the installer and purchased from HTP (p/n 7450P-212).
It is also very important not to expose the condensate line to
freezing temperatures or any type of blockage. Plastic tubing
must be the only material used for the condensate line. Steel,
brass, copper, or other materials will be subject to corrosion
or deterioration. A second vent may be necessary to prevent
condensate line vacuum lock on a long horizontal run. Also,
an increase in pipe size may be necessary to allow condensate
to drain properly. Support of the condensate line may be
necessary to avoid blockage of the condensate flow.
Spark Ignition
The burner flame is ignited by applying high voltage to the
system spark electrode. This causes a spark from electrode to
ground.
Outdoor Sensor
Monitors outdoor temperature and adjusts set point to
provide greater efficiency.
C. Optional Equipment
Optional equipment available from HTP (and Part #):
• 3” Stainless Steel Vent Termination Kit (V1000)
• 4” Stainless Steel Vent Termination Kit (V2000)
• 2” PVC Concentric Vent Kit (KGAVT0501CVT)
• 3” PVC Concentric Vent Kit (KGAVT0601CVT)

• PC Connection Kit (7250P-320)
• Condensate Neutralizer (7450P-212)
• Sanitizer Booster Kit (VSBK-1200)
Part 3 - Prepare the Water Heater
Remove all sides of the shipping crate to allow the heater to
be moved into its installation location.
COLD WEATHER HANDLING - If the water heater has
been stored in a very cold location (BELOW 0oF) before
installation, handle with care until the components come to
room temperature. Failure to do so could result in damage to
the water heater.
Carefully consider installation when determining heater
location. Please read the entire manual before attempting
installation. Failure to properly take factors such as heater
venting, piping, condensate removal, and wiring into account
before installation could result in wasted time, money, and
possible property damage and personal injury.
7
A. Locating the Water Heater
This water heater is certified for indoor use only. DO NOT
INSTALL OUTDOORS. Outdoor installations ARE NOT
covered by warranty. Failure to install the water heater
indoors could result in property damage, severe personal
injury, or death.
Incorrect ambient conditions can lead to damage to the
heating system and put safe operation at risk. Ensure that
the installation location adheres to the information included
in this manual. Failure to do so could result in property
damage, serious personal injury, or death. Failure of heater
or components due to incorrect operating conditions IS NOT
covered by product warranty.
This water heater must be installed upright in the vertical
position as described in this manual. DO NOT attempt to
install this water heater in any other orientation. Doing so
will result in improper water heater operation and property
damage, and could result in serious personal injury or death.
1. Installation Area (Mechanical Room) Operating Conditions
• Ensure ambient temperatures are higher than 32oF /
0oC and lower than 104oF / 40oC
• Prevent the air from becoming contaminated by the
products, places, and conditions listed in this manual
• Avoid continuously high levels of humidity
• Never close existing ventilation openings
• Ensure a minimum 1” clearance around hot water and
exhaust vent pipes
• NOTE: To prevent condensing in the fan, it is
recommended to avoid prolonged exposure to
temperatures below 45oF
This water heater has a condensate disposal system that
may freeze if exposed to sustained temperatures below 32oF.
Precautions should be taken to protect the condensate trap
and drain lines from sustained freezing conditions. Failure
to take precautions could result in property damage, severe
personal injury, or death.
2. Check for nearby connections to:
• System water piping
• Venting connections
• Gas supply piping
• Electrical power
• Condensate drain
3. Check area around heater. Remove any combustible
materials, gasoline, and other flammable liquids.
The service life of the water heater’s exposed metallic surfaces,
such as the casing, as well as internal surfaces, such as the heat
exchanger, are directly influenced by proximity to damp and
salty marine environments. In such areas higher concentration
levels of chlorides from sea spray coupled with relative humidity
can lead to degradation of water heater components. In these
environments, heaters must not be installed using direct vent
systems which draw outdoor air for combustion. Such heaters
must be installed using room air for combustion. Indoor air
will have a much lower relative humidity, and hence potential
corrosion will be minimized.
High heat sources (generating heat 100oF / 37oC or greater, such
as boiler flue pipes, space heaters, etc.) may damage plastic
components of the water heater as well as plastic vent pipe
materials. Such damages ARE NOT covered by warranty. It is
recommended to keep a minimum clearance of 8” from high
heat sources. Observe heat source manufacturer instructions,
as well as local, state, provincial, and national codes, laws,
regulations, and ordinances when installing this water heater
and related components near high heat sources.
Locate the water heater where any leakage from the relief valve,
related piping, tank, or connections will not result in damage
to surrounding areas or lower floors of the building. The water
heater should be located near a floor drain or installed in a drain
pan. Leakage damages ARE NOT covered by warranty.
Failure of the water heater or components due to incorrect
operating conditions IS NOT covered by product warranty.
4. Gas control system components must be protected from
dripping water during operation and service.
5. If the heater is to replace an existing heater, check for and
correct any existing system problems, such as:
• System leaks
• Location that could cause the system and heater to
freeze and leak
• Incorrectly sized expansion tank
6. Clean and flush system when reinstalling a heater.
NOTE: When installing in a zero clearance location, it may
not be possible to read or view some product labeling. It is
recommended to make note of the heater model and serial
number.
NOTE: A combustible door or removable panel is acceptable
front clearance.
B. Leveling
In order for the condensate to properly flow out of the collection
system, the area where you locate the heater must be level.
Location must also fully support the weight of the filled water
heater.
Failure to keep the water heater area clear and free of
combustible materials, liquids, and vapors can result in
substantial property damage, severe personal injury, or
death.
LP-179 Rev. 4.8.16

C. Clearances for Service Access
D. Residential Garage and Closet Installations
All water heaters eventually leak. It is recommended to install
a catch pan beneath the water heater. This catch pan should be
sized with a maximum depth of 2”, and a minimum diameter 2”
greater than the diameter of the water heater. The catch pan
should empty into an open drain line. This drain line should be
3/4” ID minimum, piped to an open drain. Failure to follow these
instructions could result in property damage. Such damages
ARE NOT covered by product warranty.
Check with your local Authority Having Jurisdiction for
requirements when installing the water heater in a garage
or closet. Please read the entire manual before attempting
installation. Failure to properly take factors such as venting,
piping, condensate removal, and wiring into account before
installation could result in wasted time, money, and possible
property damage and personal injury.
Precautions
If the heater is located in a residential garage, per ANSI Z223.1:
• Install the water heater burner and ignition devices a
minimum of 18” above the floor of the garage. This will
ensure the burner and ignition devices are well off the
floor.
• When raising the water heater ensure the entire
bottom and fully filled weight of the water heater are
fully supported.
• Locate or protect the water heater so it cannot be
damaged by a moving vehicle.
The space must be provided with correctly sized combustion/
ventilation air openings for all other appliances located in the
space with the water heater. For power venting installations
using room air for combustion, refer to the venting section,
this manual, for descriptions of confined and unconfined
spaces. Do not install the water heater in an attic. Failure
to comply with these warnings could result in substantial
property damage, severe personal injury, or death.
E. Exhaust Vent and Intake Pipe
The heater is rated ANSI Z21.10.3 Category IV (pressurized
vent, likely to form condensate in the vent) and requires a
special vent system designed for pressurized venting.
NOTE: The venting options described here (and further
detailed in the Venting section, this manual) are the lone
venting options approved for this water heater. Failure
to vent the water heater in accordance with the provided
Figure 1 - Catch Pan Dimensions and Recommended Service venting instructions will void the warranty.
Clearances
NOTE: In addition, on PHM models, it is recommended to
provide a minimum service clearance of 6” from the top of the
water heater to allow for piping of the top ports. Depending
on the installation, this clearance may need to be substantially
greater than 6”.
NOTE: If you do not provide the minimum clearances shown in
Figure 1 it might not be possible to service the heater without
removing it from the space.
The space must be provided with combustion / ventilation air
openings correctly sized for all other appliances located in the
same space as the heater. The heater cover must be securely
fastened to prevent the heater from drawing air from the
heater room. This is particularly important if the heater is in a
room with other appliances. Failure to comply with the above
warnings could result in substantial property damage, severe
personal injury, or death.
LP-179 Rev. 4.8.16
Failure to vent the water heater properly will result in serious
personal injury or death.
Do not attempt to vent this water heater by any means other
than those described in this manual. Doing so will void the
warranty and may result in severe personal injury or death.
Vents must be properly supported. Heater exhaust and
intake connections are not designed to carry heavy weight.
Vent support brackets must be within 1’ of the heater and
the balance at 4’ intervals. Heater must be readily accessible
for visual inspection for first 3’ from the water heater. Failure
to properly support vents could result in property damage,
severe personal injury, or death.
The exhaust discharged by this water heater may be very hot.
Avoid touching or other direct contact with the exhaust gases
of the vent termination assembly. Doing so could result in
severe personal injury or death.
9
1. Direct Vent of Exhaust and Intake
If installing a direct vent option, combustion air must be drawn
from the outdoors directly into the water heater intake and
exhaust must terminate outdoors. There are three basic direct
vent options detailed in this manual: 1. Side Wall Venting, 2.
Roof Venting, and 3. Unbalanced Venting.
Be sure to locate the heater such that the exhaust vent and
intake piping can be routed through the building and properly
terminated. Different vent terminals can be used to simplify
and eliminate multiple penetrations in the building structure
(see Optional Equipment in Venting Section). The exhaust
vent and intake piping lengths, routing, and termination
methods must all comply with the methods and limits given
in the Venting Section, this manual.
When installing a combustion air intake from outdoors, care
must be taken to utilize uncontaminated combustion air. To
prevent combustion air contamination, see Table 2.
2. Indoor Combustion Air in Confined or Unconfined Space
This heater requires fresh, uncontaminated air for safe
operation and must be installed in a mechanical room where
there is adequate combustion and ventilating air. NOTE: To
prevent combustion air contamination, see Table 2.
Combustion air from the indoor space can be used if the space
has adequate area or when air is provided through a duct or
louver to supply sufficient combustion air based on the water
heater input. Never obstruct the supply of combustion air to
the water heater. If the water heater is installed in areas where
indoor air is contaminated (see Table 2) it is imperative that the
water heater be installed as direct vent so that all combustion
air is taken directly from the outdoors into the water heater
intake connection.
Unconfined space is space with volume greater than 50
cubic feet per 1,000 BTU/hr (4.8 cubic meters per kW) of the
total input rating of all fuel-burning appliances installed in
that space. Rooms connected directly to this space through
openings not furnished with doors are considered part of the
space. See Venting Section for details.
Confined space is space with volume less than 50 cubic feet
per 1,000 BTU/hr (4.8 cubic meters per kW) of the total input
rating of all fuel-burning appliances installed in that space.
Rooms connected directly to this space through openings not
furnished with doors are considered part of the space.
When drawing combustion air from inside a conventionally
constructed building to a confined space, such space should
be provided with two permanent openings: one located 6”
(15 cm) below the space ceiling, the other 6” (15cm) above
the space floor. Each opening should have a free area of one
square inch per 1,000 BTU/hr (22cm2/kW) of the total input of
all appliances in the space, but not less than 100 square inches
(645cm2).
If the confined space is within a building of tight construction,
air for combustion must be obtained from the outdoors as
outlined in the Venting section of this manual.
When drawing combustion air from the outside into the
mechanical room, care must be taken to provide adequate
freeze protection.
Failure to provide an adequate supply of fresh combustion air can
cause poisonous flue gases to enter the living space, resulting
in severe personal injury or death. To prevent combustion air
contamination, see Table 2.
F. Prevent Combustion Air Contamination
Install intake air piping for the heater as described in the Venting
Section, this manual. Do not terminate exhaust in locations that
can allow contamination of intake air.
Ensure that the intake air will not contain any of the contaminants
in Table 2. Contaminated air will damage the heater, resulting in
possible substantial property damage, severe personal injury, or
death. For example, do not pipe intake air near a swimming pool
or laundry facilities. These areas always contain contaminants.

G. Removing a Heater from a Common Vent System
Do not install the heater into a common vent with any other
appliance. This will cause flue gas spillage or appliance
malfunction, resulting in possible substantial property damage,
severe personal injury, or death.
Failure to follow all instructions can result in flue gas spillage
and carbon monoxide emissions, causing severe personal injury
or death.
LP-179 Rev. 4.8.16

When removing an existing heater, follow the steps below.
1. Seal any unused openings in the common venting system.
2. Visually inspect the venting system for proper size and
horizontal pitch to determine if there is blockage, leakage,
corrosion, or other deficiencies that could cause an unsafe
condition.
3. If practical, close all building doors, windows, and doors
between the space in which the water heater remains connected
to the common venting system and other spaces in the building.
Turn on clothes dryers and any appliances not connected to
the common venting system. Turn on any exhaust fans, such as
range hoods and bathroom exhausts, at maximum speed. Do
not operate a summer exhaust fan. Close all fireplace dampers.
4. Place in operation the appliance being inspected. Follow the
lighting instructions. Adjust the thermostat so the appliance will
operate continuously.
5. Test for spillage at the draft hood relief opening after 5
minutes of main burner operation. Use the flame of a match or
candle or smoke from a cigarette.
6. After it has been determined that each appliance remaining
connected to the common venting system properly vents
when tested as outlined, return doors, windows, exhaust fans,
fireplace dampers, and any other gas burning appliances to their
previous condition of use.
7. Any improper operation of the common venting system
should be corrected to conform to the National Fuel Gas Code,
ANSI Z223.1. When resizing any portion of the common venting
system, the system should approach the minimum size as
determined using the appropriate tables in Appendix G of ANSI
Z223.1.

H. Water Chemistry Requirements
Chemical imbalance of the water supply may affect
efficiency and cause severe damage to the water heater
and associated equipment. HTP recommends having water
quality professionally analyzed to determine whether it is
necessary to install a water softener. It is important that the
water chemistry on both the domestic hot water and central
heating sides are checked before installing the water heater,
as water quality will affect the reliability of the system. In
addition, operating temperatures above 135oF will further
accelerate the build-up of lime scale and may shorten the
service life of the water heater. Failure of a water heater due
to lime scale build-up, low pH, or other chemical imbalance IS
NOT covered by the warranty.
Outlined below are water quality parameters that need to be
met in order for the system to operate efficiently for many
years.
Water Hardness
Water hardness is mainly due to the presence of calcium and
magnesium salts dissolved in water. The concentration of
these salts is expressed in mg/L, ppm, or grains per gallon
as a measure of relative water hardness. Grains per gallon is
the common reference used in the US water heater industry.
Hardness expressed as mg/L or ppm may be divided by 17.1
to convert to grains per gallon. Water may be classified as
very soft, slightly hard, moderately hard, or hard based on
its hardness number. The minerals in the water precipitate
out as the water is heated and cause accelerated lime scale
accumulation on a heat transfer surface. This lime scale
build-up may result in premature failure of the water heater.
Operating temperatures above 135oF will further accelerate
the build-up of lime scale and may shorten the service life of
the water heater.
Water that is classified as hard and very hard must be softened
to avoid water heater failure.
CLASSIFICATION

GRAINS/GAL

3.5 - 7
Hard
120 - 180
7 - 10.5
Very Hard
180 and over
10.5 and over
If the hardness of the water exceeds the maximum level of 7
grains per gallon, the water should be softened to a hardness
level no lower than 5 grains per gallon. Water softened as low
as 0 to 1 grain per gallon may be under-saturated with respect
to calcium carbonate, resulting in water that is aggressive and
corrosive.
pH of Water
pH is a measure of relative acidity, neutrality, or alkalinity.
Dissolved minerals and gases affect water pH. The pH scale
ranges from 0 to 14. Water with a pH of 7 is considered neutral.
Water with pH lower than 7 is considered acidic. Water with a
pH higher than 7 is considered alkaline. A neutral pH (around
7) is desirable for most potable water applications. Corrosion
damage and tank failures resulting from water pH levels
11
of lower than 6 or higher than 8 ARE NOT covered by
warranty. The ideal pH range for water used in a water heater
is 7.2 to 7.8.
Total Dissolved Solids
Total Dissolved Solids (TDS) is a measurement of all minerals
and solids dissolved in a water sample. The concentration of
TDS is usually expressed in parts per million (ppm).
Water with a high TDS concentration will greatly accelerate
lime and scale formation in the hot water system. Most high
TDS concentrations precipitate out of the water when heated.
This can generate a scale accumulation that will greatly reduce
the service life of the water heater.
The manufacturer of the water heater has no control over
water quality, especially TDS levels in your system. TDS in
excess of 2000 ppm will accelerate lime and scale formation
on the element or the heat exchanger. Water heater failure
due to TDS in excess of 2000 ppm IS NOT covered by warranty.
Failure of a water heater due to lime scale build-up IS NOT
covered by warranty.
Hardness: Less than 7 grains
Chloride levels: Less than 100 ppm
pH levels: 6 - 8
TDS: Less than 2000 ppm
Sodium: Less than 20 mG/L

obstruction in the discharge line.
• Test the operation of the relief valve after filling and
pressurizing the system by lifting the lever. Make sure
the valve discharges freely. If the valve fails to operate
correctly, immediately replace with a new properly rated
relief valve.
• Test T&P valve at least once annually to ensure the
waterway is clear. If valve does not operate, turn the
heater “off” and call a plumber immediately.
• Take care whenever operating relief valve to avoid
scalding injury or property damage.
FAILURE TO COMPLY WITH THE ABOVE GUIDELINES
COULD RESULT IN FAILURE OF RELIEF VALVE OPERATION,
RESULTING IN POSSIBILITY OF SUBSTANTIAL PROPERTY
DAMAGE, SEVERE PERSONAL INJURY, OR DEATH.
•
To protect against injury, install a mixing valve in the
water system. This valve will reduce point of use discharge
temperatures by mixing cold and hot water in branch supply
lines. Such valves are available from your local plumbing
supplier.
Table 4 details the relationship of water temperature and
time with regard to scald injury and may be used as a guide
in determining the safest water temperature for your
applications.
An ASSE 1017 or ASSE 1070 temperature limiting or mixing
valve is recommended in installations servicing disabled or
elderly persons, or children. Mixing valves do not eliminate
the risk of scalding.
To avoid scalding:
• Set the water heater set point temperature as low as
possible.
• Feel water before bathing or showering.
• If thermostatic valves are required, use devices
specifically designed for such purpose. Install these
devices in accordance with instructions provided by
the manufacturer.
Failure to install a temperature limiting or mixing valve and
follow these instructions could result in property damage,
severe personal injury, or death due to scalds.
Do not thread a cap or plug into the relief valve or relief valve
line under any circumstances! Explosion and property damage,
serious injury, or death may result.
RE-INSPECTION OF T&P RELIEF VALVES: T&P valves should

water heater, open a hot water tap to release air in the tank
and piping. All air has been purged from the system when
water runs freely from the faucets.
Applying power to the water heater when it is not full of water
will damage the heat exchanger, and could result in property
damage, serious personal injury, or death. Such damages
ARE NOT covered by water heater warranty.
• Make certain the drain valve is completely closed.
• Open the shut-off valve in the cold water supply line.
• Open the hot water faucets to allow air to vent from
the heater and piping.
• Allow sufficient time for the heater to completely fill
with water.

Part 5 - Venting and Condensate Removal
The heater must be vented as detailed in this section.
Ensure exhaust vent and intake piping complies with these
instructions regarding vent system. Inspect finished exhaust
vent and intake piping thoroughly to ensure all joints are
well secured, airtight, and comply with all applicable code
requirements, as well as the instructions provided in this
manual. Failure to properly install the vent system will result
in severe personal injury or death.
A. General
This heater is certified as a “Category IV” appliance and
requires a special venting system. The vent system will
operate with a positive pressure in the pipe. Exhaust gases
must be piped directly outdoors using the vent materials
and rules outlined in these instructions. Do not connect vent
connectors serving appliances vented by natural draft into
any portion of mechanical draft systems operating under
positive pressure. Follow the venting instructions carefully.
Failure to do so will result in substantial property damage,
severe personal injury, or death.
1. Installation should be made in accordance with the
regulations of the Authority Having Jurisdiction, local code
authorities, and utility companies which pertain to this type
of water heating equipment.
2. Install the venting system in accordance with these
instructions and with the National Fuel Gas Code, ANSI Z223.1/
NFPA 54, CAN/CGA B149, and / or applicable provisions of
local building codes.
3. This water heater must be vented with materials,
components, and systems listed and approved for Category
IV appliances.
Exhaust and intake are to be piped separately. This heater
cannot share a common exhaust or intake with multiple
appliances. Failure to follow these instructions will result
in substantial property damage, severe personal injury, or
death.
NOTE: To avoid contamination often contained in indoor
air, it is best to pipe all intake combustion air directly to the
outdoors.
NOTE: If exhaust vent pipe system passes through an
unheated space such as an alcove or attic, the space must be
heated.
Improper seating of vent pipe gaskets can cause eventual
gasket failure and exhaust gas leakage. Ensure the exhaust
vent pipe is properly beveled and seated before insertion
into the flue adapter. Failure to do so could result in property
damage, severe personal injury, or death.
LP-179 Rev. 4.8.16
Due to the extreme flammability of most glues, cements,
solvents, and primers used to join plastic exhaust vent and
intake pipes, explosive solvent vapors must be cleared from
all vent piping before start-up. Avoid using excess cement or
primer, as this may pool in the vent pipes. Vent assemblies
should be allowed to cure for a period of at least 8 hours
before powering a connected appliance. Failure to follow these
instructions will result in substantial property damage, severe
personal injury, or death. It is the installers’ responsibility to
understand the hazards associated with explosive solvents and
take the necessary precautions to avoid these risks.
CPVC, Polypropylene, or Stainless Steel pipe material MUST be
used for the first 3 feet of the vent run if the exhaust vent passes
through an enclosed space greater than 6”, such as a wall. The
balance of the vent run can be installed with standard Schedule
40 PVC pipe. Failure to comply with this warning could result in
property damage, severe personal injury, or death.
Exhaust vent adaptors are not designed as load-bearing
devices, and must not be used to support exhaust vent piping.
All vent pipes must be properly connected, supported, and
the exhaust vent must be pitched a minimum of 1/4” per foot
back to the heater to allow drainage of condensate. Failure to
properly support vent piping and follow the information in this
statement could result in product damage, severe personal
injury, or death.

C. Additional Requirements for Installation in Canada
DO NOT mix components from different venting systems. The
vent system could fail, causing leakage of flue products into the
living space. Use only the approved pipe and fitting materials,
and primer and cement specifically designed for the material
used, as listed in the above table. Failure to do so could result in
property damage, serious injury, or death.
High heat sources (generating heat 100oF / 37oC or greater, such
as boiler flue pipes, space heaters, etc.) may damage plastic
components of the water heater as well as plastic vent pipe
materials. Such damages ARE NOT covered by warranty. It is
recommended to keep a minimum clearance of 8” from high
heat sources. Observe heat source manufacturer instructions,
as well as local, state, provincial, and national codes, laws,
regulations, and ordinances when installing this water heater
and related components near high heat sources.
1. Installations must be made with a vent pipe system certified
to ULC-S636. IPEX is an approved vent manufacturer in Canada
supplying vent material listed to ULC-S636. Additionally,
you may use AL29-4C stainless steel venting to comply with
Canadian requirements.
2. The first three (3) feet of vent pipe from the water heater
flue outlet must be readily accessible for visual inspection.
3. The components of the certified vent system must not
be interchanged with other vent systems or unlisted pipe /
fittings.
NOTE: The use of double-wall vent or insulated material for the
combustion air intake pipe is recommended in cold climates to
prevent the condensation of airborne moisture in the incoming

E. Exhaust Vent and Intake Pipe Sizing
1. The exhaust vent and intake pipe size is 2” for 100 and 130kBTU
models and 3” for 160 and 199kBTU models.
2. The maximum total equivalent length of 2” exhaust vent and
intake pipe should not exceed 85 feet. The maximum total
equivalent length of 3” exhaust vent and intake pipe should not
exceed 200 feet.
a. The equivalent length of elbows, tees, and other fittings
are listed in the Friction Loss Table.

b. For example: If the exhaust vent has two 90o elbows and
10 feet of PVC pipe we will calculate:
Exhaust Vent Equivalent Length = (2x5) + 10 = 20 feet.
Further, if the intake pipe has two 90o elbows, one 45o elbow,
and 10 feet of PVC pipe, the following calculation applies:
Intake Pipe Equivalent Length = (2x5) + 3 + 10 = 23 feet.
Finally, if a concentric kit is used we find:
Total Equivalent Length = 20 + 23 + 3 = 46 feet.
The total equivalent length is 46 feet, well below the
maximum of 85 feet for 2” pipe.
c. Effort should be made to keep a minimum difference in
equivalent length between the exhaust vent and intake pipe.
3. The minimum total equivalent length is 16 feet.
Do not exceed the maximum lengths for vent pipes. Excessive
length could result in heater shutdown and property damage.
Failure to provide a minimum total vent length of 16 equivalent
feet could result in property damage and improper product
operation.
F. Longer Vent Runs
The maximum total equivalent length can be extended by
increasing the diameter of both the exhaust vent and intake
pipes equally. However, the transitions should begin a minimum
of 15 equivalent feet from the water heater.
a. The maximum total equivalent length for increased
diameter vent pipes is 125 feet for 2” transitioning to 3” pipe
(this length includes the minimum 15 total equivalent feet
necessary for transition).
NOTE: 3” vent pipe can be increased in diameter, but total
equivalent length cannot be increased beyond 200 feet.
b. Transitions should always be made in vertical sections of
pipe to prevent the condensate from pooling in the vent
pipe.

defined in this manual. 125 maximum total equivalent feet for
2” increased to 3” vent pipe; 200 maximum total equivalent
feet for any increase to 3” vent pipe diameter. Failure to keep
the total equivalent length below the maximum lengths

G. Exhaust Vent and Intake Pipe Installation
All joints of positive pressure vent systems must be sealed
completely to prevent leakage of flue products into the living
space. Failure to do so could result in property damage,
serious injury, or death.
1. Use only solid PVC, CPVC, or stainless steel pipe or a
Polypropylene vent system approved for use with Category IV
appliances.
FOAM CORE PIPING IS NOT APPROVED FOR EXHAUST
VENT APPLICATIONS. Foam core piping may be used on air
inlet piping only.
2. Remove all burrs and debris from joints and fittings.
3. When using PVC or CPVC pipe, all joints must be properly
cleaned, primed, and cemented. Use only cement and primer
approved for use with the pipe material. Cement must
conform to ASTM D2564 for PVC and ASTM F493 for CPVC
pipe. NOTE: DO NOT CEMENT POLYPROPYLENE PIPE.
4. Ensure the vent is located where it will not be exposed to
prevailing winds.
5. In all roof venting applications, exhaust discharge must
point away from the pitch of the roof.
6. If the exhaust vent is to be terminated in a walled off area
LP-179 Rev. 4.8.16
24
(such as a roof with a parapet wall), ensure the exhaust vent
terminates a minimum of 10’ from nearest wall and extends
level with or above the top of the wall. This will ensure flue gas
does does not get trapped and possibly recirculated into the
intake air pipe, which could contaminate the combustion air.
7. To prevent water leakage, install adequate roof flashing
where the pipe enters the roof.
8. Do not locate vent over public walkways, driveways, or
parking lots. Condensate could drip and freeze, resulting in a
slip hazard or damage to vehicles and machinery.
9. Due to potential moisture build-up, sidewall venting may
not be the preferred venting option. To save time and cost,
carefully consider venting installation and location.
10. Horizontal lengths of exhaust vent must slope back
towards the water heater not less than ¼” per foot to allow
condensate to drain from the vent pipe.
11. The exhaust vent must terminate where vapors cannot
make accidental contact with people or pets, or damage
shrubs or plants.
12. In vacant chimney applications, install and seal a rain cap
over existing chimney openings.
13. All piping must be fully supported. Use pipe hangers at a
minimum of 4 foot intervals to prevent sagging of the pipe
where condensate may form.
14. Do not use the heater to support any piping.
15. A screened straight coupling is provided with the heater
for use as an outside exhaust termination.
16. A screened inlet air tee is provided with the heater to be
used as an outside intake termination.

H. Applications
1. Direct Vent Installation of Exhaust and Intake
If installing a direct vent option, combustion air must be drawn
from the outdoors directly into the water heater intake, and
exhaust must terminate outside. There are three basic direct
vent options detailed in this manual: 1. Side Wall Venting, 2.
Roof Venting, and 3. Unbalanced Venting.
Be sure to locate the heater such that the exhaust vent and
intake pipe can be routed through the building and properly
terminated. Different vent terminals can be used to simplify
and eliminate multiple penetrations in the building structure
(see Optional Equipment in Venting Section). The exhaust
vent and intake pipe lengths, routing and termination
methods must all comply with the methods and limits given
in the Venting section of this manual.
When installing a combustion air intake from outdoors, care
must be taken to utilize uncontaminated combustion air.
NOTE: To prevent combustion air contamination, see Table 2.

UNBALANCED VENTING
WITH TEE (INTAKE)
AND COUPLING (EXHAUST)
Contractors must check state and local codes before installing
through an existing vent opening. State and local codes always
take precedence over manufacturer’s instructions. Failure to
check state and local codes before installing through an existing
opening could result in property damage and add significantly
to installation costs.
If an existing venting system is converted for use with this heater,
the installer must ensure that the existing venting system
is clean and free from particulate contamination that could
damage the heater. Failure to do so could result in property
damage and heater failure. Such failure IS NOT covered under
warranty.

3. Indoor Combustion Air in Confined or Unconfined Space
This heater requires fresh, uncontaminated air for safe operation
and must be installed in a mechanical room where there is
adequate combustion and ventilating air. NOTE: To prevent
combustion air contamination, see Table 2.
Combustion air from the indoor space can be used if the space
has adequate area or when air is provided through a duct or
louver to supply sufficient combustion air based on the water
heater input. Never obstruct the supply of combustion air to
the water heater. If the water heater is installed in areas where
indoor air is contaminated (see Figure 20) it is imperative that the
water heater be installed as direct vent so that all combustion air

I. Condensate Removal System
NOTE: Check with your local gas company to determine if
combustion condensate disposal is permitted in your area. In
the state of Massachusetts, condensate must be neutralized
before entering a drain.
This condensing high efficiency water heater has a condensate
removal system. Condensate is water vapor derived from
combustion products, similar to that produced by an automobile
when it is initially started. It is very important that the condensate
line is sloped down away from the heater and to a suitable drain.
If the heater condensate outlet is lower than the drain, you must
use a condensate removal pump (kit p/n 554200 available from
HTP). If required by local authorities, a condensate filter of lime
crystals, marble, or phosphate chips will neutralize slightly acidic
condensate. This can be installed in the field and purchased from
HTP (p/n 7450P-212).
The condensate line must remain unobstructed. If allowed to
freeze in the line or obstructed in any other manner, condensate
can exit from the water heater tee, resulting in potential water
damage to property. When installing a condensate pump, select
one approved for use with condensing heaters and furnaces. The
condensate pump should have an overflow switch to prevent
property damage from spillage. Condensate from the heater
will be slightly acidic (pH from 3.2 to 4.5). Install a neutralizing
filter if required by local codes.
INDOOR COMBUSTION AIR
(SINGLE PIPE)
Power to the optional condensate pump is continuous. When the
water heater is powered off the condensate pump will remain
on. It is important to remember to turn off the condensate pump
when powering down the water heater. Failure to do so could
result in property damage, severe personal injury, or death.

1. Condensate line must be pitched at least ¼” per foot to
properly drain. If this cannot be done, or a very long length
of condensate hose is used, increase the condensate line to a
minimum of 1” ID and place a tee in the line after the condensate
neutralizer to properly reduce vacuum lock in the drain line.
2. PVC or CPVC pipe should be the only material used for
condensate line. Steel, brass, copper, and other metals will be
subject to corrosion or deterioration.
3. A frozen condensate line could result in a blocked vent
condition. It is very important to protect the condensate line from
29
freezing temperatures or any type of blockage. In installations
that may encounter sustained freezing conditions, the use of
heat tape is recommended to avoid freezing of the condensate
line. It is also recommended to bush up the condensate line size
to 1” and terminate condensate discharge as close to the unit as
possible. Longer condensate runs are more prone to freezing.
Damages due to frozen or blocked condensate lines ARE NOT
covered by warranty.
4. Support of the condensate line may be necessary to avoid
blockage of the condensate flow.
Part 6 - Wiring
To avoid electrical shock, turn off all power to the heater prior
to opening an electrical box within the unit. Ensure the power
remains off while any wiring connections are being made.
Failure to follow these instructions could result in component or
product failure, serious injury, or death. Such product failure IS
NOT covered by warranty.
Jumping out control circuits or components WILL VOID product
warranty and can result in property damage, personal injury, or
death.
A. Line Voltage Input
The heater must be wired to a 120 volt circuit by a qualified
electrician. It is recommended that the heater be wired on its
own circuit to minimize the possibility of circuit failure due to
outside clauses. The heater requires a maximum of 8 amps at
120 volts in use.
B. Line Voltage Condensate Output
The heater has the capability of supplying power to a condensate
pump. The connection is 120 VAC +/- 10% at a max of 2 amps.
Power is supplied to the pump only when the heater is connected
to power, and the power switch is in the on position.
C. Low Voltage Outdoor Sensor Input
The heater has the capability of an outdoor reset. Connecting
an outdoor sensor allows the heater to operate at optimum
efficiency. HTP offers an outdoor sensor, p/n 7250P-319.
The outdoor sensor must be a 12K NTC sensor. Use a minimum
22 AWG wire for runs of 100 feet or less and minimum 18 AWG
wire for runs up to 150 feet. Instructions are included with the
outdoor sensor to correctly mount the sensor on the exterior
surface of the building. It is preferable to mount the sensor
on the north side in an area that will not be affected by direct
sunlight but will be exposed to varying weather conditions.
Connect the outdoor sensor to terminals marked “Outdoor”.
It is of extreme importance that this unit be properly grounded. It
is very important that the building system ground is inspected by
a qualified electrician prior to making this connection. Electrical
power must only be turned on when the heater is completely
filled with cold water. Failure to follow these instructions could
result in component or product failure, serious injury, or death.
An ASSE 1017 thermostatic mixing valve MUST be installed
when using 0-10V or outdoor reset. Failure to do so could result
in substantial property damage, serious injury, or death.
Label all wires prior to disconnecting them when servicing
the heater. Wiring errors can cause improper and dangerous
operation. Failure to follow these instructions may result in
property damage or personal injury.
D. Alarm Connections
The control includes an alarm
output. This circuit is rated at 3 amps
at 120 volts. This contact can be used
to activate an alarm light or bell
or notify a building management
system if the water heater goes into
a lockout condition.
E. Optional 0-10 Volt Building
Control Signal
A signal from a building
management system may be
connected to the water heater to
enable remote control. This signal
should be a 0-10 volt positivegoing DC signal. When this input is
enabled using the installer menu, a
building control system can be used
to control the set point temperature
of the water heater. The control
interprets the 0-10 volt signal as
follows; when the signal is between
0 and 1.5 volts, the water heater
will be in stand-by mode, not firing.
When the signal rises above 1.5
volts, the water heater will ignite. As
the signal continues to rise towards
its maximum of 10 volts, the water
heater will increase in set point
temperature. See Part 10 for details
on the setting of function 16.
Figure 23 - Field Wiring
NOTE: During 0-10V operation, the
minimum tank temperature set point (default 95oF) will be at
the activation input of 1.5 volts. The maximum temperature
set point value will be at the input voltage of 10 volts. The
maximum temperature set point can be changed by increasing
or decreasing the DU setting (Range: 77oF – 160oF / Default
119oF). Once programmed, the 0-10V feature will change the
set point temperature automatically.
1. Connect a building management system or other auxiliary
control signal to the terminals marked 0-10 VOLT + and
0-10 VOLT – in the electronics assembly (shown in Figure
25). Caution should be used to ensure that the 0-10 VOLT +
connection does not become connected to ground.
2. Configuring the appliance for 0-10 volt operation (change
only the functions in the descriptions below):
a. Press and hold S3 and S4 together for 5 seconds
b. Use S1 and S2 to adjust flashing 000 to code 975. Press S3
until you enter the menu.
c. Use S3 to scroll to Function 16 to enable/disable 0-10 volt
operation. Use S1 and S2 to adjust display to desired setting
(Range: 0 = Off, 2 = On / Default Off).
d. Press and hold S4 to exit the menu.

Part 7 - Gas Connections
Failure to follow all precautions could result in fire, explosion,
severe injury, or death.
Ensure the gas on which the water heater will operate is the
same type specified on the rating plate. Failure to do so could
result in water heater malfunction, property damage, personal
injury, or death.
The gas supply shall have a maximum inlet pressure of less
than 14” water column (350 mm), ½ pound pressure (3.5
kPa), and a minimum of 3.5” water column. The entire piping
system, gas meter and regulator must be sized properly to
prevent pressure drop greater than 0.5” WC as stated in the
National Fuel Gas Code. This information is listed on the rating
plate.
It is very important that you are connected to the type of gas
as noted on the rating plate: “LP” for liquefied petroleum,
propane gas, or “Nat” for natural or city gas. All gas
LP-179 Rev. 4.8.16
32
connections must be approved by the local gas supplier or
utility, in addition to the governing authority, prior to turning
the gas supply on.
Do not remove the adaptor in Figure 26! It is mandatory that
this fitting is used for connection to a field fabricated drip leg
per the National Fuel Gas Code. You must ensure that the
entire gas line to the connection at the water heater is no
smaller than 3/4”.
Once all inspections have been performed, the piping must
be leak tested. If the leak test requirement is a higher test
pressure than the maximum gas inlet pressure, you must
isolate the heater from the gas line to continue leak testing.
To do this, you must turn off the factory and field-installed gas
cocks. This will minimize the possibility of damaging the gas
valve. Failure to do so may damage the gas valve. In the event
the gas valve is exposed to a pressure greater than ½ PSI, 14”
water column, the gas valve must be replaced. Never use an Figure 26 - Gas Connection
open flame (match, lighter, etc.) to check gas connections.
B. Gas Table
UL recognized fuel gas detectors are recommended in
all enclosed propane and natural gas applications where
there is a potential for an explosive mixture of fuel gas to
accumulate. The installation of these detectors should
be made in accordance with the detector manufacturer’s
recommendations, and/or local laws. Failure to install fuel gas
detectors in these applications could result in fire, explosion,
property damage, severe personal injury, or death.
A. Gas Piping
Run the gas supply line in accordance with all applicable
codes. Locate and install manual shutoff valves in accordance
with local and state requirements.
Support gas supply piping with hangers, not by the heater
or its accessories. The heater gas valve and blower will not
support the weight of the piping. Make sure the gas piping
is protected from physical damage and freezing, where
required. Failure to follow these instructions could result in
gas leakage, and result in fire, explosion, property damage,
severe personal injury, or death.
Do not use Teflon tape on gas line pipe thread. Use a pipe
compound rated for use with natural and propane gases.
Apply sparingly on male pipe ends, leaving the two end
threads bare. Failure to follow these instructions could result
in gas leakage, and result in fire, explosion, property damage,
severe personal injury, or death.
Refer to the table below to size the supply piping to minimize
pressure drop between meter or regulator and unit.
Maximum capacity of pipe in cubic feet of gas per hour for gas
pressures of .5 psi or less and a pressure drop of .3 inch water
column.
It is recommended that a soapy solution be used to detect leaks.
Bubbles will appear on the pipe to indicate a leak is present.
The gas piping must be sized for proper flow and length of pipe
to avoid excessive pressure drop. Both the gas meter and the
gas regulator must be properly sized for the total gas load. If
you experience a pressure drop greater than 1” WC, the meter,
regulator or gas line is undersized or in need of service. You can
attach a manometer to the incoming gas drip leg by removing
the cap. The gas pressure must remain between 3.5” WC and
14” WC during stand-by (static) mode and while in operating
(dynamic) mode at full output.
If an in-line regulator is used, it must be a minimum of 10 feet
from the heater. It is very important that the gas line is properly
purged by the gas supplier or utility. Failure to properly purge
the lines or improper line sizing will result in ignition failure.
This problem is especially noticeable in NEW LP installations
and also in empty tank situations. This can also occur when
a utility company shuts off service to an area to provide
maintenance to their lines. The gas valve must not be replaced
with a conventional gas valve under any circumstances. As an
additional safety feature, the gas valve in this water heater has a
flanged connection to the swirl plate and blower.

Do not do a gas conversion on this water heater without an
officially approved conversion kit and instructions supplied
by HTP. Failure to use a conversion kit when converting the
heater to fire on Natural or Propane gas will result in extremely
dangerous burner operation, leading to fire, explosion, severe
personal injury, or death.
Strain on the gas valve and fittings may result in vibration,
premature component failure and gas leakage, and result in fire,
explosion, property damage, severe personal injury, or death.
Adjustments to the throttle screw or offset may only be made
by a qualified gas technician using a calibrated combustion
analyzer capable of measuring CO2 and CO. Failure to follow
this instruction could result in fire, explosion, property damage,
severe personal injury, or death.

Part 9 - Start-Up Procedure
FOR YOUR OWN SAFETY READ BEFORE OPERATING
1. This water heater does not have a pilot. It is equipped with
an ignition device which automatically lights the burner. Do
not try to light the burner by hand.
2. BEFORE OPERATING: Smell all around the water heater
area for gas. Be sure to smell next to the floor because some
gas is heavier than air and will settle on the floor.
WHAT TO DO IF YOU SMELL GAS
• Do not try to light any water heater.
• Do not touch any electric switch, do not use any phone
in your building.
• Immediately call your gas supplier from a neighbor’s
phone. Follow the gas suppliers’ instructions.
• If you cannot reach your gas supplier, call the fire
department.
• Turn off the gas shutoff valve (located outside the water
heater) so that the handle is crosswise to the gas pipe.
If the handle will not turn by hand, don’t try to force
or repair it, call a qualified service technician. Force or
attempted repair may result in a fire or explosion.
4. Do not use this water heater if any part has been under
water. Immediately call a qualified service technician to
inspect the water heater and to replace any part of the control
system and any gas control that has been damaged.
5. The water heater shall be installed so the gas ignition
system components are protected from water (dripping,
spraying, rain, etc.) during water heater operation and
service (circulator replacement, condensate trap, control
replacement, etc.)
Failure to follow these instructions could result in property
damage, serious personal injury, or death.
A. Operating Instructions

F. Maintenance
The control system requires no periodic maintenance under
normal conditions. However, in unusually dirty or dusty
conditions, periodic vacuuming of the cover to maintain
visibility of the display and indicators is recommended. In dirty
environments, such as construction sites, care must be taken
to keep the water heater burner cover in place and drywall or
saw dust away from water heater.
LP-179 Rev. 4.8.16
36
D. Important Notice
In unusually dirty or dusty conditions care must be taken
to keep water heater burner door in place. Failure to do so
VOIDS warranty.
Allowing the heater to operate with a dirty combustion
chamber will hurt operation. Failure to clean the heat
exchanger as needed by the installation location could result
in heater failure, property damage, personal injury, or death.
Such product failures ARE NOT covered under warranty.
It is extremely important that whenever work is performed on
the plumbing system that either:
• The water heater is powered off, or,
• The water heater is valved off and isolated from the
plumbing system.
Failure to take these measures could result in a dry-firing
condition.

C. Failure to Operate
Should the burner fail to light, the control will perform two
more ignition trials prior to entering a lockout state. Note that
each subsequent ignition trial will not occur immediately. After
a failed ignition trial, the blower must run for approximately
10 seconds to purge the system. Therefore, a time period of
approximately 40 to 90 seconds will expire between each
ignition trial.
If the burner lights during any one of these three ignition
trials, normal operation will resume. If the burner lights, but
goes off in about 4 seconds, check the polarity of the wiring.
See electrical connection section of this manual.
If the burner does not light after the third ignition trial, the
control will enter a lockout state. This lockout state indicates
that a problem exists with the water heater, the controls, or
the gas supply. Under such circumstances, a qualified service
technician should be contacted immediately to properly
service the water heater and correct the problem.
If a technician is not available, pressing the S4 button will
remove the lockout state so additional trials for ignition can
be performed. The unit will try to relight once every 6 minutes.
LP-179 Rev. 4.8.16
The water heater must be full of water and the system fully
purged BEFORE powering the water heater. Performing any
work in the plumbing system without either powering off
the water heater or isolating the water heater through the
use of shut-off valves could result in a condition referred to
as “dry-firing”. Dry-firing the water heater will damage the
heat exchanger, and could result in property damage, serious
personal injury, or death. Such damages ARE NOT covered by
water heater warranty.
Part 10 - Troubleshooting
A. Error Code
An error code may occur during installation of the heater. This
condition may lead to a lock out condition of the controller, which
will need to be manually reset by pressing S4. The following
information will help the installer correct the problem before
going into a lockout condition, which will require a manual reset.
37
B. Heater Error
1. When an error condition occurs the controller will display an
error code on the display module.
2. These error codes and several suggested corrective actions
are included in Table 16.
3. In the case of E00, E13, and E14 error codes, if uncorrected,
the water heater will go into a fault condition as described in
section C. Lockout.
C. Lockout
1. When an fault condition occurs, the controller will illuminate
the red fault indication light and display a fault code (example:
F00).
2. Note the fault code and refer to Table 17 for an explanation
of the fault code along with several suggestions for corrective
actions.
3. Press S4 to clear the fault and resume operation. Be sure to
observe the operation of the unit to prevent a recurrence of the
fault.
The water heater has wire function labels on all internal wiring.
Observe the position of each wire before removing it. Wiring
errors may cause improper and dangerous operation. Verify
proper operation after servicing.
DO NOT USE THIS APPLIANCE IF ANY PART HAS BEEN
SUBMERGED IN WATER. Immediately call a qualified service

Table 18 - Installation Checklist
Part 12 - Maintenance
In unusually dirty or dusty conditions, care must be taken to
keep water heater cabinet door in place at all times. Failure to
do so VOIDS the warranty.
Allowing the water heater to operate with a dirty combustion
chamber will hurt operation. Failure to clean the heat
exchanger as needed by the installation location could result
in water heater failure, property damage, personal injury,
or death. Such product failures ARE NOT covered under
warranty.
Hydrogen gas can build up in a hot water system served by
this water heater that has not been used for a long period
of time (generally two weeks or more). When opening a hot
water faucet in a system that has been out of use for a time,
keep all ignition sources (electrical appliances, open flame,
etc.) away from the faucet. If hydrogen is present, there will
be a sound of air escaping as water begins to flow. Allow the
water to run for a few minutes to dissipate built up hydrogen
from the system. Failure to follow these instructions can
result in property damage, personal injury, or death.
The water heater requires minimal periodic maintenance
under normal conditions. However, in unusually dirty or dusty
conditions, periodic vacuuming of the cover to maintain
visibility of the display and indicators is recommended.
LP-179 Rev. 4.8.16
Periodic maintenance should be performed once a year by a
qualified service technician to assure that all the equipment
is operating safely and efficiently. The owner should make
necessary arrangements with a qualified heating contractor for
periodic maintenance of the heater. Installer must also inform
the owner that the lack of proper care and maintenance of the
heater may result in a hazardous condition.
It is extremely important that whenever work is performed on
the plumbing system that either:
• The water heater is powered off, or,
• The water heater is valved off and isolated from the
plumbing system.
Failure to take these measures could result in a dry-firing
condition.
The water heater must be full of water and the system fully
purged BEFORE powering the water heater. Performing any
work in the plumbing system without either powering off
the water heater or isolating the water heater through the
use of shut-off valves could result in a condition referred to
as “dry-firing”. Dry-firing the water heater will damage the
heat exchanger, and could result in property damage, serious
personal injury, or death. Such damages ARE NOT covered by
water heater warranty.
