BOILER INSTALLATION
INSTALLATION REGULATIONS
This unit should be installed in accordance with the regulations of the authority having jurisdiction. In
Canada the installation must conform to CSA Standard B139, "The Installation Code for Oil Burning
Equipment." In the United States, the National Fire Protection Association Standard NFPA 31 should be
followed. Check with provincial, state, or local codes concerning clearances, venting system requirements
and other regulations governing installation. Some codes may vary from the requirements set forth in this
manual.
FOUNDATION
To ensure the boiler is on a level foundation and above any possible dampness, a cement pad is
recommended.
CLEARANCES
The minimum clearances to combustible construction are as follows:
6"
Side: 6” Top: 6”
Rear: 6”
Front: 24" Flue Pipe: 9" Approved Floor Type: Combustible
Allow sufficient room for servicing.
FOR YOUR SAFETY: Do not store or use gasoline or flammable vapors and liquids in the vicinity
of this or any other appliance.
VENTING PRODUCTS OF COMBUSTION
Chimneys
The required minimum flue pressure is -0.02 inches of water column. The required minimum overfire
pressure is -0.005 inches of water column. Locate the boiler as close to the chimney or flue as possible.
The maximum draft is obtained by keeping elbows and pipe length to a minimum. Install the flue pipe with
a gradual rise of at least 1/4" per foot from the boiler to the flue. Do not extend the flue pipe beyond the
inside wall of the chimney. Refer to Table 8 (a) and Table 8 (b) for proper sizing and Figure 19 for
optimizing chimney draft.
The owner shall provide a chimney constructed to comply with the following specifications:
(a) The chimney must be absolutely smoke tight throughout its entire length, and must extend at least
three feet (3') above a flat roof or two feet above the ridges of peak roofs.
(b) If built of a single thickness of brick or of cement blocks, it shall be lined throughout its entire length
with fire clay lining, having not less than three-fourths inch (3/4") thickness. Flue lining is to be laid in
mortar and made air tight. If the chimney is of the prefabricated type, it must be an approved class "A"
chimney or type "L" Vent for interior.
(c) The boiler flue must have no other openings for attaching any fireplace, stove, range, gas or ventilating
connection unless the equipment is appropriately certified.
(d) If it is necessary to offset the flue, it must be done in such a manner as not to reduce the gross crosssectional area or create a ledge or obstruction, where loose material may lodge.
(e) Flue pipe connections must be secured with metal screws.
CAUTION: Oil-fired appliances shall be connected to flues or vents having sufficient draft at all
times to ensure safe and proper operation of the appliance.
Barometric Draft Regulator
The Listed/Certified draft regulator must be installed between the appliance and the chimney, within easy
reach for adjustment and free from obstruction. Use larger or multiple draft regulators for chimneys with
strong draft. Follow the draft regulator manufacturer's instructions for proper installation.
Power Venting
Consult installation codes for requirements and approvals governing power venters and draft inducers.
Follow the instructions supplied with them for proper installation.
3
Newmac Sealed Vent System
Consult the GENERAL INSTRUCTIONS of this manual for approved burners. Follow the instructions
supplied with the SVS system for proper installation.
PIPING
Locate the boiler as close as possible to the center of the heat distribution system and make sure the top
is level. Typical Piping Layouts are shown in Figure 10 and Figure 11.
Radiant Floor Piping
Only pipe certified for in floor applications should be used. Cross-linked polyethylene (PEX) pipe with the
ASTM F876 designation is widely used. Polybutylene (Poly B) has a lower temperature and pressure
rating than PEX and is more susceptible to kinking. Non-metallic pipes must have an oxygen diffusion
barrier to prevent oxygen molecules from passing through their walls. Oxygen entering the hydronic
system may cause degradation of the components.
AIR PURGE
Air in water at normal atmospheric conditions promotes corrosion. Since corrosion is a chemical reaction
and chemical reactions increase with temperature, at boiler operating temperatures the corrosion factor
must not be overlooked. Air can also cause noise and circulation problems. Once in operation and
purged of air the only source of new air should be the makeup water. Automatic air vents placed at high
points in the piping system usually will relieve this problem. Installation of a microbubble resorber air
eliminator (Spirovent) in the supply line is highly recommended.
Chemical Additives
A corrosion inhibitor is required to further guard against oxygen in the system and growth of anaerobic
bacteria. Glycol should only be used if the possibility of freezing exists--a non-toxic propylene glycol must
be used. Glycol significantly decreases the system efficiency, therefore the minimum amount should be
used.
ELECTRICAL CONNECTIONS
Standard boiler models are rated at 120 V, 60 Hz, 1-Phase, 15 Amp Fuse. Other voltages are available.
Refer to the certification label prior to making electrical connections. Follow the National Electrical Code
as well as provincial, state, and local regulations. Figure 12 shows a standard wiring schematic.
WARNING: Make sure the electrical lockout switch is operating properly. Power to the burner
should be interrupted when the front access cover is opened or removed.
THERMOSTAT
The thermostat should be located on an interior wall free from drafts approximately 5 feet above floor
level. The operation of the burner is normally controlled by the room thermostat, which may be set for the
temperature desired, typically 70 F. If a higher or lower temperature is desired, the indicator should be set
to the proper point on the scale. To shut down the burner at any time, turn the main power switch off. To
prevent short cycling, the heat anticipator must be set at 0.2 amps as indicated in Figure 1. This
adjustment shuts the burner down to prevent the room temperature from exceeding the thermostat
setting.
FIGURE 1 Heat Anticipator
WARNING: The heat anticipator will
BURN OUT if 25 volts are applied
directly to the thermostat by shorting
out the primary control during testing
or incorrect wiring. If this happens
the thermostat warranty is void.
4
GAUGES
The pressure and temperature gauge supplied with the boiler has a 1/4” NPT connection. Refer to Figure
9 for its location.
TANKLESS DOMESTIC HOT WATER COIL
For boilers equipped with tankless coils, installing the aquastat in the top tapping is not recommended.
Mounting the aquastat on the coil plate allows the burner to respond faster to flow through the tankless
coil increases the availability of domestic hot water. In area where hard water may be a problem, a water
softener is recommended. Mineral deposits will reduce heat transfer and restrict flow. An indirect storage
tank is recommended if high consumption of domestic hot water is anticipated.
BACKFLOW PREVENTER
To prevent contamination of potable water a backflow preventer is required. Be sure the inlet side is
connected to the domestic water supply. Do not use a single check valve for this purpose.
FLOW CHECK VALVES
Use a flow check to prevent thermal siphoning or gravity flow when the circulator is off. Pump differential
is required to open the valve. Observe flow direction when installing these valves.
PRESSURE RELIEF VALVE
A 30 p.s.i pressure relieve valve is supplied with the appliance to protect against excessive water pressure
caused by thermal expansion of the water or emergency steam conditions caused by runaway overfiring.
It has 3/4” NPT for connection to the top (highest point) of the boiler. Refer to Figure 9 for its location.
Orient the valve vertically and so that blow off is directed out of harms way. To avoid water damage, a
drain pipe of the same size as the valve outlet can be connected --it must be pitched down. An occasional
drip from the valve is normal. Do not install a shut off valve between the outlet and disposal site. The
blowdown pipe should terminate about six inches from the floor for unrestricted flow, preferably near a
floor drain. Replacement valves should have the same rating as the original one and be ASME approved.
Relief valves are rated according to B.T.U.H.
LOW WATER CUT-OFF
Some jurisdictions may require a safety control to guard against low water situations. A ¾ NPT tapping is
provided to mount this control directly on the boiler
PRESSURE REGULATING VALVE
A pressure regulating valve is not part of the standard controls package. Since local regulations may
require installation of this type of valve they are available as an option from Newmac. The function of this
control valve is to regulate the boiler feed water to 12 or 15 psig to compensate for the water main working
pressure which may be excessive. For convenience these valves incorporate an internal bypass for fast
filling and air purging of the system. It must be mounted in a horizontal position in the cold water supply
upstream from a shut-off valve. Be sure the flow direction arrow is pointing toward the system.
EXPANSION TANK
Water expands as it is heated. Normal operation requires the boiler and piping to be full of water. As the
water is heated an airtight tank located above the boiler provides a place for the additional volume of water
to go. With a compression tank air trapped in the system will migrate to the upper part of the tank above
the water level. The tank should be sized based on the boiler output rating and the water capacity of the
system.
AQUASTAT CONTROL
This control has a probe mounted in a well and immersed in the boiler water to sense temperature. It is
thermally operated with three settings to regulate boiler water temperature for space heating equipment
and domestic hot water service. The operation of the Honeywell control as shown in Figure 2 is discussed
here. Refer to Figure 9 for its location.
High Limit Setting: This setting regulates burner operation. When the high limit setting is reached on
temperature rise dangerous overheating of the boiler is prevented by cutting power to the burner. The
temperature has to fall by 10 F before power is restored .
Note: The high limit must be set at least 20 F higher than the low limit setting.

Low Limit Setting: This setting controls the minimum standby temperature. It regulates circulator and
burner operation. When the low limit setting is reached as the boiler water temperature increases the
burner circuit breaks and the pump starts circulation of hot water. The circulator continues to operate to
satisfy the call for heat from the thermostat until the water temperature falls 10 F below the set point. The
burner circuit makes when the water temperature falls 10 F below the low limit set point.
Differential Setting: This setting only effects the low limit operation. The circulator make and burner break
temperature can be elevated by raising this setting. This temperature will be the set point temperature
plus the difference between the differential setting and 10 F. The differential setting does not change the
burner make and circulator break temperature. The recommended aquastat settings are as follows:
HI 180
LO 160
DIFF 20
Aquastat Control Operating Sequence with Room Thermostat Calling: The burner starts if the boiler water
temperature is less than 170 F. With the low limit set at 160 and the differential set at 20 F, the circulator
starts on a temperature rise at 170 F. The circulator runs distributing hot water through the system until
the temperature falls to 150 F. When the high limit setting of 180 F is reached the burner shuts off. The
burner will restart as the temperature falls by 10 F to 170 F.
Aquastat Control Operating Sequence with Room Thermostat not Calling: With the low limit set at 160 and
the differential set at 20 F the burner shuts off at 170 (low limit setting minus 10 F plus the differential
setting). The burner restarts when the boiler water temperature falls below 150 F (low limit setting minus
10 F).

OPTIONAL AQUASTAT CONTROLS
The Honeywell L7124U Electronic Aquastat is approved as an alternate control. White Rodgers 8B43A601 is certified. Honeywell L6006A and L4006A can also be used.
CIRCULATOR
Flush the system to remove foreign matter. Operate the circulator for 5 minutes immediately after filling
the system to purge air pockets.

MIXING METHODS
A method of mixing is required for boiler protection with low temperature systems. The minimum return
water temperature required is 135 F.
Mixing Valves
A three-way mixing valve can be used in most conventional systems such as baseboard radiation as long
as a minimum return water temperature of 135 F can be maintained.
A four-way mixing valve is commonly used for radiant floor applications. This will allow blending to
maintain the relatively high boiler loop temperatures while sustaining the lower temperatures required for
radiant floor heating. Most mixing valves can be controlled manually or with an automatic motor.
Injection Systems
Controls for mixing using variable speed injection pumps, on/off injection pumps and on/off injection
valves are readily available.
ZONE VALVES
Conventional zone valves operate in either a fully open or fully closed position. Most are normally closed
until the thermostat calls for heat. Some models have an end switch that activates the circulator when the
valve is fully open. Some newer valves are designed to modulate flow.
ANTI-SCALD VALVES
An automatic thermostatically controlled tempering valve is required to prevent scalds. It should be
located approximately 10 inches below the domestic hot water supply outlet. This will keep the valves bimetallic thermostat element from sensing non-flowing hot water. Manually operated valves are not
suitable for use as anti-scald valves.
HOT WATER EXTENDER TEMPERING VALVES
A good quality valve is recommended to mix the domestic hot water supplied by the tankless coil or
indirect storage tank with the cold water supply to produce a comfortable temperature. The ability of the
valve to maintain a constant temperature is proportional to the quality of the valve. The valve must be
installed according to the valve manufacturer’s instructions with a suitable balancing valve and thermal
heat trap if specified.
DHW BALANCING VALVE
A modulating type valve should be used to achieve the desired blend of hot and cold water.
FLOW RESTRICTOR
A flow restrictor valve is often used for constant flow, energy conservation and water management. These
valves are useful where high temperature is required and flow rate can be reduced. Flow restrictors are
available that are designed for tankless heater applications. For systems with pressures exceeding 50 psi
it is good practice to install a flow restrictor.
OUTDOOR RESET CONTROL
This control adjusts the water temperature supplied to the distribution system according to the required
heating load. The supply water is controlled automatically based on the correlation between the required
supply water temperature and actual outdoor temperature. Boiler outdoor reset should not be used is a
tankless coil is used.
GATE VALVES
Gate valves are designed for component isolation. They should be fully open or fully closed. A ball valve
can be used as a lower cost alternative.
GLOBE VALVES
Flow regulation can be accomplished with globe valves.

BLOCKED VENT SWITCH
The WMO-1 blocked vent control is required on Newmac oil-fired and combination furnaces or boilers
installed in Canada. The WMO-1 switch must be installed on the chimney vent pipe for Newmac oil fired
furnaces and boilers; and installed on the burner plate for Newmac combination wood/oil or coal/oil fired
furnaces. Do not use the WMO-1 Blocked Vent Switch with the Newmac Sealed Vent System (SVS).
Refer to the Newmac and Field Controls Instructions enclosed in the WMO-1 package.

FUEL SYSTEMS
Fuel not heavier than No. 2 fuel oil must be used. The oil tank must be of an approved type--ULC labeled
in Canada and ULI labeled in the United States. Install the oil storage tank or tanks according to local
codes and regulations. The supply tank should be kept at least 1/4 full. Suction and return lines should
be of the same diameter and extend to the same depth in the tank. An emergency oil shut-off valve
should be installed as required by local ordinance. This can be manual, electric solenoid, or vacuum
operated. An oil safety valve that cuts the fuel supply unless a vacuum is created by the pump is
recommended. Any leaks in the system will prevent oil from flowing. Suntec PRV or Webster OSV valves
are recommended.
COMBUSTION AND VENTILATION AIR
Free air for combustion and ventilation must be permanently provided to the boiler room. Combustion air
refers to the total air requirements of the fuel burning appliance. This includes air for the combustion
process and air to provide chimney draft (dilution air). Ventilation air ensures free circulation of air in the
room where the appliance is located to keep ambient temperatures within safe limits under normal
conditions.
Boilers installed in tight houses, in houses with unbalanced air flows, or in enclosed spaces are very likely
to have homeowners complain of smoke, fumes, burner lockouts, and excessive fuel consumption. This
is more prevalent in post 1985 construction due to the tighter building construction as prescribed by the
latest building codes. Regulations are relatively specific on the minimum allowable quantities of ventilation
and combustion air required once the space category is determined. However, every house is subjected
to different internal and external conditions and regulations vary among localities. With this in mind,
Newmac requires provision for combustion and ventilation air as specified in Table 1. Table 1 is based
on; relevant codes and regulations, assumptions, generalizations, and simplifications.
Values indicated in Table 1 are based on the maximum input rating. However, in making combustion and
ventilation analysis the aggregate input rating of all appliances in the space must be considered.
The installation of additional oil-fired appliances may require more combustion and ventilation air.
Allowances must also be made for the blocking effect of louvers, grilles and screens. If the design and
8
free area is unknown, assume wood louvers have 20-25% free area and metal louvers and grilles have
60-75% free area. Screens should not be less than 1/4 inch mesh.

The free area of ducts specified in Table 1 assume air is conveyed from outdoors.
The following should be kept in mind when using Table 1:








All applicable codes and regulations must be followed.
Unconfined free area values for openings to outdoors are based on 1 sq in per 5,000 Btu/hr of the
maximum input rating.
Confined free area of vertical ducts is based on 1 sq in per 4,000 Btu/hr of the maximum input rating.
Confined free area of horizontal ducts is based on 1 sq in per 2,000 Btu/hr of the maximum input
rating.
Two openings of equal size are required for confined spaces.
Maximum length of run for ducts is 50 ft. Duct size allowances must be made for longer runs.
Ducts should be designed or insulated to prevent condensation. If insulating, a minimum insulation
value of R-3 is required.
In the case where one opening or duct is specified and combustion and ventilation air is still
inadequate, a second duct may be required. Locate one high and the other low for air circulation.
It is particularly important to duct the cold air as close to the appliance as possible. A means of
closing the air openings when the appliance is not operating may be required.
Guidelines to determine the need for additional combustion and ventilation air may not be
adequate for every situation. If in doubt, it is advisable to err on the safe side and provide
additional air.
Figure 3 shows a typical appliance installation. In this case there is a furnace and a water heater in an
enclosed space--both require ventilation and combustion air which is delivered by the top and bottom air
ducts. As long as adequate combustion and ventilation air is supplied, this type of arrangement offers
several advantages:






The incoming cold air is confined to the furnace room. Therefore, the occupants are less susceptible
to drafts. Cool outdoor air will be tempered by the ambient temperature of the furnace room before it
enters habitable spaces.
Noise levels may be reduced.
The furnace will be less susceptible to combustion spillage and backdrafting in low draft situations
reducing odor and smoke. Moderate amounts of smoke and fumes will be contained and expelled
safely outdoors.
Incomplete combustion of any carbon based fuel may produce deadly carbon monoxide. Ventilation
may dilute any CO produced under abnormal operating conditions.
Adequate air for combustion will yield the proper air fuel ratio. Appliances burning fuel rich will
produce soot and burn excessive fuel quantities. A 1/8 inch thick deposit of soot on the surface of the
heat exchanger is equivalent to 1 inch of fiberglass insulation.
Modern efficient furnaces and boilers tend to be physically smaller than their predecessors. As a
result, hot surfaces such as flue connectors are not as high as they used to be. A separate furnace
room with a “child proof” door is an important safety precaution.

OIL BURNER OPERATING INSTRUCTIONS
BURNER CARE
This burner is fully automatic in operation. All adjustments should be made by a qualified technician.
Keep the burner free from excess dirt and moisture. Oil leaks should be tended to immediately. The
motor should be given a few drops of SAE 20 non-detergent oil at least two or three times a year. No
other parts require lubrication.
CAUTION: Do not use gasoline, crankcase or any oil containing gasoline. Do not tamper with the
unit or controls--call the serviceman. Do not attempt to start the burner when excess oil has
accumulated, when the unit is full of vapor or when the combustion chamber is very hot. Do not
start the burner unless the cleanout doors are secured in place. Do not burn garbage or paper in
the heating system. Never leave combustible materials such as paper or rags near the unit.
OIL BURNER INSTALLATION
Install the oil nozzle in the burner firing assembly, and check the adjustments. Figure 5 and Table 2 can
be used to obtain the correct electrode settings. These settings are critical for proper burner operation.
Some burner manufacturers have a gauge available for setting the electrodes. Most burners with
adjustable heads have preset stops to ensure the distance from the nozzle face to the face of the
retention head (“Z” dimension) is correct. Set the air tube insertion depth according to Figure 6 and Table
2. This is the distance from the face of the mounting flange to the face of the retention head.
Use the GENERAL INSTRUCTIONS in this manual for preliminary air settings for the burner.

Riello Burner End Cone Protector
FIGURE 4 Riello Burner End cone Protector
Riello burners are equipped with a ceramic fibre
sleeve to protect the end cone. The end cone
protector is mounted by rotating it back and forth
as it is slid over the burner end cone and air
tube. It should be flush with the face of the end
cone or extend no more than ¼” beyond the end
of the tube assembly. Refer to Figure 4.
Carefully insert the burner air tube into the
combustion chamber without damaging or
moving the ceramic sleeve. The end cone
protector can be replaced without removing the burner by swinging the front smoke box open. Mount the
oil burner on the 4 lugs of the smoke box. Installing or removing the burner without removing the burner
mounting flange is not recommended.
START-UP AND ADJUSTMENT
SET-UP INSTRUMENTS
The installer must use a suitable draft gauge, smoke tester, carbon dioxide tester, 0-750 F stack
thermometer, 0-200 psi oil pressure gauge, 0-30 in. Hg. vacuum gauge, and 0-220 F thermometer to
properly set-up the burner.
1. Turn on supply power and set the thermostat above room temperature.
2. Open all oil lines and valves.
3. Make sure the oil pump by-pass plug is correctly located for a one or two pipe system. Bleed the oil
pump (refer to pump manufacture's instructions).
4. Adjust the air band on the burner until a #1 smoke or less is reached using a smoke tester. If a smoke
tester is unavailable, slowly close the air band until the fire becomes smoky. Slowly increase the air
until a small amount of smoke is observed at the flame tips.
- If the unit fails to start, check: (a) oil supply; (b) ignition electrodes and transformer; (c) cad cell.
- If the burner goes off on safety, do not push the reset button on the primary control for at least 10
minutes.
Do not push the reset button more than once before correcting the cause. If the burner still does
not start, press the reset on the burner motor.
5. Using a draft meter, adjust the barometric draft regulator to measure -0.02 inch water column. This
requires that a 5/16" diameter sampling hole be made between the flue collar and the draft regulator.
SEASONAL OR EXTENDED SHUT DOWN PERIODS
When the burner is not to be used for an extended period of time, set the thermostat at its lowest value,
turn off the main switch and close the oil burner supply valve. If the heating unit room is damp, protect the
burner against dirt and moisture with a light cover. To resume operation, remove the cover and inspect
the burner. Remove any dirt and debris gently to avoid the need to adjustment the air band. Open the
supply valve and turn on the main switch. If the burner fails to operate see the MAINTENANCE &
SERVICE section of this manual.

MAINTENANCE & SERVICE
Maintenance and servicing must be done by a qualified burner technician or shortened boiler life and poor
efficiency may result. Under Tests and Observations and Requirements in CSA B139, the installer is
required to perform tests to ensure proper and safe operating conditions. Newmac requires the installer to
fill out the INSTALLER INFORMATION sheet found in this manual.
The heat exchanger and firetubes should be inspected on an annual basis. If cleaning is required, open
or remove smoke boxes--take care not to break the ceramic liners or gaskets. Use a wire brush
(available from Newmac) to loosen scale and soot and a vacuum cleaner to remove it from the boiler.
Replace gaskets if necessary before closing or replacing the smoke boxes. A layer of soot on the heat
exchanger surfaces and firetube walls will reduce heat transfer and can increase fuel consumption
significantly. A 1/32” layer of soot acts as an insulator and can result in a 3% increase in oil burned.
Likewise a 1/16” layer may result in an average fuel loss of 8%.
OIL FILTER
The oil filter should be cleaned or replaced at least once a year by the serviceman. Use a 10 micron or
better filter. We recommend General Filters Model GF-CGF10 (refill GF-K10GF) or Garber Model 11BVR.
OIL PUMPS & FUEL SYSTEMS
Make sure the by-pass plug is correctlly located for a one or two pipe system. Failure to do so may
damage the pump. Generally, for 3/8” copper tubing the vertical lift should not exceed 8 feet and the
horizontal run should be limited to 30 feet. Do not exceed 10 p.s.i. inlet line pressure.
Single pipe systems are recommended for gravity feed or when the tank outlet is at a higher elevation
than the pump inlet. Refer to Figure 8 (a). The inlet vacuum should be no more than 6" Hg.
Two pipe systems are recommended for lift feed or when the pump inlet is at a higher elevation than the
tank outlet. Install the return line termination higher than the supply intake as shown in Figure 8 (a).
Generally, the inlet vacuum should be no more than 12" Hg.
Correct piping is critical to long-term operation of the fuel system. Never use compression fittings.
Minimize the resistance to flow due to excessive line lengths; high lift; and unnecessary fittings, kinks and
bends. This will decrease the running vacuum and the risk of air seperation. A “Tigerloop” fuel oil deaerator may improve the performance of poorly designed fuel oil delivery systems.
Pressure Check
Install the pressure gauge directly on the gauge or nozzle port. Adjust to the pressure specified by
Newmac for the nozzle input rating. Refer to the GENERAL INSTRUCTIONS in this manual or the
certification label.

RETURN & BY-PASS PORT
Each oil burner should have its own suction line. A
common return line can be used as long as the
diameter is large enough. Check valves are not
required on properly installed systems. Service on fuel
units should not be attempted without a suitable
vacuum and pressure gage.
The information presented here is intended as a
guide only. For piping system design data, consult
the installation instructions from the pump
manufacturer.
FLEXIBLE OIL LINE
The flexible oil supply line shipped with the boiler must be installed between the oil pump and the oil line
from the storage tank. For a two pipe system a similar flexible return line is required and may be obtained
from your distributor. See Figures 8 (a) and 8 (b).

NBR (LIMITED) B0ILER WARRANTY
Effective July 1, 1995 and subject to the following conditions Newmac Manufacturing Inc. warrants the Oil Fired BOILER, to the original owner purchaser,
under normal use and repair, against defects in workmanship and materials for a period of one calendar year from the date of original installation. This
warranty does not cover nozzles, filters, etc. that may be contaminated at time of installation.
The burner, controls or any other electrical or mechanical components not manufactured by Newmac are warranted for a period of one year from date
of original installation by their respective manufacturers; most burners have 3 years.
Effective July 1, 1995 and on the date of original installation Newmac warrants for a period of twenty (20) years to the original purchaser that the
Boiler Shell of the NBR Oil Fired BOILER will be free from defects in material and workmanship provided however, this warranty shall apply only to the
original installation of the BOILER in a single dwelling unit used without interruption by the purchaser as his or her principal residence. This warranty is
subject to the conditions and exceptions of warranty listed below.
Under the above warranty Newmac Mfg. at its option will repair or replace the shell under the above terms or offer the then current applicable retail
price of a boiler shell towards a new equivalent BOILER. Proof of original purchase will be required.
The warranty must be registered within 30 days of installation or the following pro-rated warranty “Twenty Year Warranty” applies.
Where the owner of the dwelling is not the original purchaser and in multi-family dwellings Newmac warrants the boiler shell against defects in
materials and workmanship under a 20 year Limited Warranty subject to the conditions and exceptions listed below and on a prorated basis as follows of

The purchaser must pay all other costs of warranty service including labor costs involving diagnostic calls and or removing, servicing and or replacing
warranty parts and or warehousing charges and or freight costs. All parts are supplied F.O.B. Debert, Nova Scotia and the defective parts must be
returned freight prepaid for repair and or warranty consideration when requested by Newmac Mfg.
CONDITIONS
This warranty refers to the Boiler SHELL only. In order for this warranty to be effective:
1. The BOILER must be installed by a qualified licensed installer and in accordance with Newmac’s installation instructions. The BOILER must also be
installed in accordance with all applicable, local states, or provincial codes and the INSTITUTE of BOILER and RADIATIOR MFG.. or generally accepted
equivalent standards.
2. The BOILER must operate in an environment not contaminated by halogens (such as but not limited to fluorine or chlorine) or chlorinated
hydrocarbons. These corrosive chemicals entering the combustion area cause rapid deterioration of inner surfaces leading to heat exchanger failures.
The BOILER must be maintained and cleaned on an annual basis by qualified personnel. Oil filters and nozzles must be changed annually.
3. The BOILER must be sized and fired correctly as stated on the label for the residence. The label must not have been defaced or removed.
4. The BOILER must not be modified from its published design or purpose.
5. The BOILER must not have been removed from the original installation site.
6. Warranty on the boiler, when used with a Floor Radiant Heat System will only be valid if tubing with complete OXYGEN BARRIER is used.
7. There must be adequate combustion air installed to the BOILER room; and in the case of sidewall venting there must be adequate ventilation air in
addition to combustion air to prevent depressurization of the home.
8. Warranty components may be replaced with reconditioned parts at the discretion of Newmac Mfg.
9. Proof of original purchase will be requested under this warranty.
10. Proof of failure must be supplied in writing within (30) days of failure.
EXCEPTIONS
1. All labor, freight or diagnostic calls, removal and replacement costs and warehousing charges are the responsibility of the purchaser including the
return to Debert, Nova Scotia of defective parts.
2. Defects or damages caused by failure of the refractory chamber, improper installation, wiring, electrical current characteristics, accident, misuse or
abuse, fire, flood, alteration and or misapplication of the product, default or delay in performance; caused by war, government restrictions, restraints,
strikes, material or freezing.
3. Refractory chamber, nozzles, etc...
4. Defects or damages caused by nozzle failure and/or plugging and/or oil flow restrictions due to cold oil from outside tanks or misalignment of burner
at installation.
5. This warranty in no way can be considered as a guarantee of workmanship of an installer connected with the installation of the Newmac Oil Fired
BOILER or as imposing on Newmac any liability of any nature for unsatisfactory performance as a result of faulty workmanship in the installation which
liability is expressly disclaimed.
6. This warranty will not be applicable if the BOILER is damaged or a result of being improperly serviced or operated.
LIMITATIONS ON WARRANTY
Newmac will make no express warranties other than the warranty set forth above. All implied warranties including the implied warranties of a
merchantability and fitness for a particular purpose are limited to the duration of the express warranty, set forth above. Liability for incidental and
consequential damages are excluded regardless of the cause. Some provinces in Canada and some states in the U.S.A. do not allow limitations on how
long an implied warranty lasts so the above may not apply to you. The expressed warranties made in this warranty are exclusive and may not be altered,
enlarged or changed by any distributor, dealer or any other person whatsoever. All replacement parts whether new or remanufactured, assume as their
warranty period on the remaining period of this warranty. For routine service requirements contact the dealer who installed the equipment originally, or
an alternate qualified and registered heating dealer or electrical.
