SAFETY INFORMTION FOR USERS OF LP-GAS
Propane (LP-Gas) is a flammable gas which can cause fires and
explosions. In its natural state, propane is odorless and colorless.
You may not know all the following safety precautions which can
protect both you and your family from an accident. Read them
carefully now, then review them point by point with the members
of your household. Someday when there may not be a minute to
lose, everyone's safety will depend on knowing exactly what to
do. If, after reading the following information, you feel you still
need more information, please contact your gas supplier.
LP-GAS WARNING ODOR
If a gas leak happens, you should be able to smell the gas because of the odorant put in the LP-Gas.
That's your signal to go into immediate action!
• Do not operate electric switches, light matches, use your phone.
Do not do anything that could ignite the gas.
• Get everyone out of the building, vehicle, trailer, or area. Do
that IMMEDIATELY.
• Close all gas tank or cylinder supply valves.
• LP-Gas is heavier than air and may settle in low areas such as
basements. When you have reason to suspect a gas leak, keep
out of basements and other low areas. Stay out until firefighters
declare them to be safe.
• Use your neighbor's phone and call a trained LP-Gas service
person and the fire department. Even though you may not
continue to smell gas, do not turn on the gas again. Do not
re-enter the building, vehicle, trailer, or area.
• Finally, let the service man and firefighters check for escaped
gas. Have them air out the area before you return. Properly
trained LP-Gas service people should repair the leak, then
check and relight the gas appliance for you.
NO ODOR DETECTED - ODOR FADE
Some people cannot smell well. Some people cannot smell the
odor of the chemical put into the gas. You must find out if you
can smell the odorant in propane. Smoking can decrease your
ability to smell. Being around an odor for a time can affect your
sensitivity or ability to detect that odor. Sometimes other odors
in the area mask the gas odor. People may not smell the gas odor
or their minds are on something else. Thinking about smelling a
gas odor can make it easier to smell.
The odorant in LP-gas is colorless, and it can fade under some
circumstances. For example, if there is an underground leak, the
movement of the gas through soil can filter the odorant. Odorants
in LP-Gas also are subject to oxidation. This fading can occur if
there is rust inside the storage tank or in iron gas pipes.
The odorant in escaped gas can adsorb or absorb onto or into walls,
masonry and other materials and fabrics in a room. That will take
some of the odorant out of the gas, reducing its odor intensity.
LP-Gas may stratify in a closed area, and the odor intensity could
vary at different levels. Since it is heavier than air, there may be
more odor at lower levels. Always be sensitive to the slightest gas
odor. If you detect any odor, treat it as a serious leak. Immediately
go into action as instructed earlier.
SOME POINTS TO REMEMBER
• Learn to recognize the odor of LP-gas. Your local LP-Gas
Dealer can give you a "Scratch and Sniff" pamphlet. Use it to
find out what the propane odor smells like. If you suspect that
your LP-Gas has a weak or abnormal odor, call your LP-Gas
Dealer.
• If you are not qualified, do not light pilot lights, perform service,
or make adjustments to appliances on the LP-Gas system. If
you are qualified, consciously think about the odor of LP-Gas
prior to and while lighting pilot lights or performing service
or making adjustments.
• Sometimes a basement or a closed-up house has a musty smell
that can cover up the LP-Gas odor. Do not try to light pilot
lights, perform service, or make adjustments in an area where
the conditions are such that you may not detect the odor if
there has been a leak of LP-Gas.
• Odor fade, due to oxidation by rust or adsorption on walls of
new cylinders and tanks, is possible. Therefore, people should
be particularly alert and careful when new tanks or cylinders
are placed in service. Odor fade can occur in new tanks, or
Page 4
reinstalled old tanks, if they are filled and allowed to set too
long before refilling. Cylinders and tanks which have been out
of service for a time may develop internal rust which will cause
odor fade. If such conditions are suspected to exist, a periodic
sniff test of the gas is advisable. If you have any question about
the gas odor, call your LP-gas dealer. A periodic sniff test of
the LP-gas is a good safety measure under any condition.
• If, at any time, you do not smell the LP-Gas odorant and you
think you should, assume you have a leak. Then take the same
immediate action recommended above for the occasion when
you do detect the odorized LP-Gas.
• If you experience a complete "gas out," (the container is under
no vapor pressure), turn the tank valve off immediately. If the
container valve is left on, the container may draw in some air
through openings such as pilot light orifices. If this occurs,
some new internal rusting could occur. If the valve is left
open, then treat the container as a new tank. Always be sure
your container is under vapor pressure by turning it off at the
container before it goes completely empty or having it refilled
before it is completely empty.

Note: Never use plastic pipe. Check to confirm whether your local
codes allow copper tubing or galvanized.
Note: Since some municipalities have additional local codes, it is
always best to consult your local authority and installation code.
The use of the following gas connectors is recommended:
— ANS Z21.24 Appliance Connectors of Corrugated Metal Tubing
and Fittings
— ANS Z21.45 Assembled Flexible Appliance Connectors of
Other Than All-Metal Construction
The above connectors may be used if acceptable by the authority
having jurisdiction. The state of Massachusetts requires that a flexible
appliance connector cannot exceed three feet in length.
A manual main gas cock should be located in the vicinity of the unit.
Where none exists, or where its size or location is not adequate, contact your local authorized installer for installation or relocation.
Compounds used on threaded joints of gas piping shall be resistant
to the action of liquefied petroleum gases. The gas lines must be
checked for leaks by the installer. This should be done with a soap
solution watching for bubbles on all exposed connections, and if
unexposed, a pressure test should be made.
Never use an exposed flame to check for leaks. Appliance must
be disconnected from piping at inlet of control valve and pipe
capped or plugged for pressure test. Never pressure test with
appliance connected; control valve will sustain damage!
A gas valve and ground joint union should be installed in the gas
line upstream of the gas control to aid in servicing. It is required by
the National Fuel Gas Code that a drip line be installed near the gas
inlet. This should consist of a vertical length of pipe tee connected
into the gas line that is capped on the bottom in which condensation
and foreign particles may collect.
Pressure Testing of the Gas Supply System
1. To check the inlet pressure to the gas valve, a 1/8" (3mm) N.P.T.
plugged tapping, accessible for test gauge connection, must be
placed immediately upstream of the gas supply connection to
the appliance.
2. The appliance and its individual shutoff valve must be
disconnected from the gas supply piping system during any
pressure testing of that system at test pressures in excess of 1/2
psig (3.5 kPa).
3. The appliance must be isolated from the gas supply piping
system by closing its individual manual shutoff valve during any
pressure testing of the gas supply piping system at test pressures
equal to or less than 1/2 psig (3.5 kPa).
Attention! If one of the procedures results in pressures in excess
of 1/2 psig (14" w.c.) (3.5 kPa) on the fireplace gas valve, it will
result in a hazardous condition.
Checking Manifold Pressure
Both Propane and Natural gas valves have a built-in pressure
regulator in the gas valve. Natural gas models will have a manifold
pressure of approximately 3.5" w.c. (.872kPa) at the valve outlet
with the inlet pressure to the valve from a minimum of 5.0" w.c.
(1.245kPa) for the purpose of input adjustment to a maximum of
10.5" w.c. (2.614kPa) Propane gas models will have a manifold
pressure approximately 10.0" w.c. (2.49kPa) at the valve outlet
with the inlet pressure to the valve from a minimum of 11.0" w.c.
(2.739kPa) for the purpose of input adjustment to a maximum of
13.0" w.c. (3.237kPa).
A 1/8" (3mm) N.P.T. plugged tapping, accessible for test gauge
connection, is located on the outlet side of the gas control.

CLEARANCES
1. Pick a location on a wall with a clear space of 36" (91.4cm)
high by 43" (109cm) wide in the room. In selecting a location
for installation, it is necessary to provide adequate accessibility
clearances for servicing and proper installation. Be sure to locate
the unit close enough to a 115 VAC wall receptacle to properly
power appliance.
2. Unit is supported by a wall bracket secured to the wall.
3. When facing the front of the furnace the minimum clearances
from casing to combustible construction are 10" (254mm) on
top, 3" (76mm) on each side, recommend 18" (457mm) on right
side for servicing and 0" (0mm) from the floor and 0" (0mm)
to rear wall.
4. The black flocked exhaust pipe, contained in DVE-1 Kit or DVE2 Kit, has zero (0") inches (0mm) clearance to combustibles.
5. The minimum distance from the center of the vent cap to the
nearest outside corner or obstruction is 12" (305mm).
6. The minimum wall depth is 2" (51mm) and the maximum is
10" (254mm) [or 32"(813mm) using the extended vent terminal
kit accessory]. The use of vent tubes not supplied by the
manufacturer may result in unsatisfactory performance.
The vent terminal of a direct vent appliance, with an input of
50,000 BTU (14.6KW) per hour or less shall be located at least 9"
(229mm) from any opening through which flue gases could enter
a building.
The bottom of the exhaust vent terminal and the air intake shall
be located at least 12" (305mm) above grade and must be vented
outside.
WARNING: The nearest point of the vent cap should be
a minimum horizontal distant of six (6) feet (1.83m) from

Venting (Figures 7, 8 and 9)
This unit is vented directly out the back using the concentric vent
tube assembly provided. See Figure 2 for vent hole location. This
hole location can be conveniently moved closer to unit exhaust
outlet tube to avoid wall stud interference if necessary. The orange
silicone exhaust elbow would need to be cut to length. Do not
locate vent directly behind the exhaust outlet. Do not use the orange
silicone elbow for extended vent runs where the possibility of
flue condensate exists unless the run is horizontal and the elbow is
sloped downward away from the heater. See Figure 12 for extended
vertical venting.
The vent provided will accommodate walls up to 10" thick and
can be cut shorter for thinner walls if desired by using a hacksaw
or cut-off saw. Be sure to leave the minimum 3/4" of tube length
extending beyond the outside wall plate. Both the inner and outer
tube will be cut to the same length as the inner exhaust tube has an
extension piece which is added during final outside assembly.

FURNACE INSTALLATION (continued)
Be sure to deburr the ends with a file after cutting. Installation is
easy after cutting the wall opening secure the vent terminal box
in place using the (4) 10 x 1" hex-head screws provided. Locate
the box so that the middle exhaust tube is directed toward the
furnace exhaust outlet opening. See Figure 8. Attach the black 2"
flexible inlet air hose to the bottom 2" connector on the vent box
using a hose clamp. Secure the other end to the lower inlet air
box connector using the hose clamp. Do not kink hose. Attach the
long straight end of the 2" orange silicone exhaust elbow to the
middle vent terminal tube and rotate the elbow toward the furnace
exhaust outlet. Secure the hose to the vent box using a hose clamp.
Carefully push the furnace back closer to the wall and secure the
exhaust elbow to the 2" exhaust tube exiting the unit. Secure the
elbow in place using the last remaining hose clamp. The furnace
can now be secured to the wall.
The furnace can be vented with up to a maximum length of 15'
(4.6m) including termination vent and using 2 - 90° elbows. Also,
the furnace can be vented with up to a maximum length of 10'
(3m) including termination vent and using 3 - 90° elbows. For
longer vent lengths order the vent kit, Part Number DVE-1 and
DVE-2. See Figures 11 and 12 illustrating extended vent run and
venting options.
Note: If the extended vent kit is used and the exhaust vent pipe
is run through a cold space, such as an attic or a garage, the pipe
should be insulated using 1/2" (13mm) thick fiberglass insulation
or equivalent to keep the flue products warm enough to avoid
condensation. Also, slope 1/4" (6mm) per foot (305mm) the vent
terminal horizontal run downward toward the outside of the house
to assure any condensate flow out of vent system. Horizontal
vent pipe runs of 5 feet (1.5m) or more in length may accumulate
condensation in the exhaust pipe and must, therefore, be sloped
downward to drain any condensate out of the end vent terminal.
Use straps or other suitable supports spaced every 5 feet (1.5m) to
adequately hold pipe. Be sure to avoid any low spots or sags in
pipe run. Be sure all connections are tight using the hose clamps
as shown in Figure 9, "Vent Coupling Connections."
For wall depths thicker than 10" (254mm) order the extended vent
terminal kit which will cover walls to 32" (813mm) thickness.
The vent pipes must be cut to length to assemble for desired wall
thickness.
For extended venting, it is also acceptable to use 2" (51mm) diameter
PVC or ABS pipe for the combustion air intake supply piping
only to the unit. If this is used, the pipe and fittings must conform
to ANSI and ASTM Standards D1785 for SCH. 40 PVC, D2665
for PVC-DWV, D2241 for SDR-21 and SDR-26 PVC, D2661 for
ABS-DWV and F628 for SCH. 40 ABS. Pipe cement and primer
must be used and conform to ASTM Standard D2564 for PVC or
D2235 for ABS. This PVC or ABS pipe must not be used for
the exhaust vent pipe run.
Note: Type SDR pipe is not approved for use in Canada.
For new construction installation, the intake and exhaust vent
can be run inside a wall, a vertical or horizontal distance prior to
exiting the wall. This can be done but not the preferred method of
installation due to the inability to perform periodic inspection of
19562-6-0314
the vent system. In doing this, it is important to securely seal the
vent system and slope all horizontal runs downward 1/4" (6mm)
per foot (305mm) toward the vent terminal outside to drain out
any condensate. It is also necessary to adequately support both the
exhaust and intake and to center the exhaust pipe in the wall.
Be sure to consult local codes prior to installation to verify allowable
procedures.
Installation of Shroud
To complete inside installation, secure furnace to the wall bracket
by attaching the two wall mounting brackets to the wall bracket
by using (2) 10 x 1/2" (13mm) hex-head screws provided (See
Figures 4 and 6). To attach the right shroud and left shroud to the
casing back, the 3/4" wide flange on the shroud must be positioned
toward the casing side. When positioned correctly, the (6) louvers
on the shroud will be facing up and the knock-out on the shroud
will be facing down. Attach the right shroud and left shroud to the
casing back with (3) 10x1/2" hex-head screws supplied in hardware
package, for each shroud. Attach top shroud to right shroud and
left shroud with (4) Phillips-head screws, supplied in hardware
package. Insert air filter into top shroud.
Attention: If the right shroud and left shroud are installed incorrectly,
with the 3/4" wide flanges facing inward, the top shroud will not
be able to be installed onto the side shrouds. The top shroud will
appear to be 2 inches, too narrow.
Vent Terminal (Figure 10)
Place the 6 3/8" x 6 3/8" (162mm x 162mm) black foam, wall plate
gasket within the mounting plate. The 4 3/4" (121mm) diameter
hole in the black foam gasket will allow for installation of the
concentric vent tube assembly. Slide the outside mounting plate into
place on the concentric vent tube assembly. The outside mounting
plate should seal against the face of the building and be secured
in place using (4) 10 x 1" hex-head screws. Be sure to caulk and
seal around the pipe on the exterior using high temperature exterior
grade, silicone caulk rated at 204°C/400°F. Wipe some silicone
sealant on the 2" (51mm) exhaust pipe extension. The end cap can
be pushed into place on the exhaust outlet tube.
Attention: The opening on the bottom of the end cap must be
positioned toward the ground. The opening on the bottom cannot
be pivoted to the right or left, it must be centered toward the
ground.

Condensate Removal (Figures 11 and 12)
The condensate drain kit is used in conjunction with DVE and
DVE-2, intake/exhaust extension kits. The condensate drain kit is
required whenever there is a vertical vent run, in a heated room [10
ft. (3m) or more for DV-40E or 6 ft. (1.8m) or more for DV-20E],
in the intake/exhaust venting.
Reassembly and Resealing Vent-Air Intake System
When vent-air intake system is removed for servicing the furnace,
the following steps will assure proper reassembly and resealing
of the vent-air intake assembly. Be sure all hose connections and
elbow assemblies are re-secured in place using the hose clamps
removed. Reattach all screws securing mounting flanges and inspect
all connections for a tight fit. Use high temperature silicone caulk
rated at 204°C/400°F to reseal the inlet air vent pipe and exhaust
air vent pipe to the mounting plate.
Whenever a vertical vent run, in a heated room [10 ft. (3m) or more
for DV-40E or 6 ft. (1.8m) or more for DV-20E] and a horizontal
vent run are combined, you must purchase the optional condensate
drain kit, part number DV-1108. If the vertical vent run lengths are
less than those required for the condensate drain kit, you can slope
the horizontal vent run portion, downward 1/4" (6mm) per foot
(.3m) to the outside. However, if local codes prohibit condensate
from draining outside and the appliance produces condensate, the
horizontal portion of the vent run must slope downward, to the
appliance, 1/4" (6mm) per foot (.3m). This will allow any condensate
to flow into the condensate drain kit. Do not use the orange silicone
elbow supplied with unit to catch condensate. You can route the
condensate from the condensate drain kit to an existing drain or
into the condensate drain pan located within the appliance.
Whenever a horizontal vent run is used, where local codes allow,
you can slope the exhaust pipe downward, to the outside, 1/4"
(6mm) per foot (305mm). The downward slope on the exhaust
pipe will allow any condensate to flow out of the exhaust pipe. If
local codes prohibit condensate from draining to the outside and
the appliance produces condensate you must purchase condensate
drain kit, part number DV-1108.

inside of the combustion (exchanger) assembly in order to clear
all passageways.
Oiling
The blower motor has an oil hole located on each end of the motor.
Use #20 motor oil only. It is best to oil the motor several times
during the heating season using 2 or 3 drops each time.
OPERATION AND TROUBLESHOOTING
Your new furnace should provide many years of trouble free
performance, however, a yearly inspection of the burners , flue
passageways and the outlet vent assembly should be done. Be
sure all passageways are open and clear of any obstruction, or soot
build up. Be sure to shut off all power to the unit while performing
this inspection.
Periodically remove the circulating air filter and clean with water
to remove all dirt. Shake dry and reinstall in unit.
System Operation
1. This furnace has an electronic thermostat and control board
to monitor the room temperature and then control the furnace
operation to provide the best comfort and performance from a
heating appliance. To operate unit turn ON/OFF switch to ON
and then turn temperature control knob clockwise slowly till
furnace turns on. For typical room comfort, the control knob
should be pointed toward medium.
2. The furnace control board follows sequence of operation which
allows for self diagnosis in the event there is a problem. The
control then blinks a status light, a set number of blinks based
on what problem has been encountered. When the furnace is
on and there is a no fault condition, the red LED is on.
On a typical call for heat by the integral thermostat 24 VAC is
applied to the W terminal on the board.
The inducer blower circuit is energized and the inducer blower
comes on for 15 seconds pre-purging out any gas and closing
the pressure switch.
19562-6-0314
The hot surface ignitor is energized and after a 17 second warmup, the gas valve circuit is energized, opening the gas valve
and igniting the burners. After burning for about 30 seconds,
the circulating air blower comes on, delivering warm air to
the room. If ignition does not occur, the ignition sequence is
repeated again up to 2 more times. (3 trials for ignition-total)
3. After the furnace operates and satisfies the thermostat, the gas
valve closes and the circulating air blower continues to run for
about 2 minutes and then shuts off. The inducer blower runs
for 5 seconds and shuts off.
If for any reason ignition and operation does not occur, the
control board will blink the red fault status LED, a sequence
code, indicating what to look for as a troubleshooting guide.
If the red LED is ON but not blinking check the electronic
temperature control to verify its operation. This can be easily done
by disconnecting the 3 electronic temperature control leads from
the main furnace board and using a pig tail jumper to connect
R & W together on the board. If the furnace comes on and runs
normally the temperature control board is malfunctioning. If
the heater still does not come on, then the main furnace board
is malfunctioning. Look for any fault codes below and verify
the 3 amp fuse is not blown.
