Sheet metal parts may have sharp edges or burrs. Use care and wear
appropriate protective clothing, safety glasses and gloves when
handling parts, and servicing furnaces
1. Use only with type of gas approved for this furnace. Refer to
the furnace rating plate.
2. Install this furnace only in a location and position as specified
in section 2.3- Location.
3. Provide adequate combustion and ventilation air to the
furnace space as specified in section 7-Venting.
4. Combustion products must be discharged outdoors. Connect
this furnace to an approved vent system only, as specified in in
section 7-Venting of these instructions.
5. Never test for gas leaks with an open flame. Use a
commercially available soap solution made specifically for the
detection of leaks to check all connections, as specified in the
“Gas Piping” section.
6. Always install furnace to operate within the furnace’s
intended temperature rise range with a duct system which has an
external static pressure within the allowable range, as specified
in section 4-Duct installation. See furnace rating label.
7. When a furnace is installed so that supply ducts carry air
circulated by the furnace to areas outside the space containing
the furnace, the return air shall also be handled by duct(s) sealed
to the furnace casing and terminating outside the space
containing the furnace. See section 4-Duct installation.
8. A gas fired furnace for installation in a residential garage
must be installed as specified in section 2.3-Location.
9. The furnace may be used for construction heat provided that
the furnace installation and operation complies with section 2.3-
Location.
10. The furnace is factory shipped for use with natural gas. A
CSA (A.G.A. and C.G.A.) listed accessory gas conversion kit is
required to convert furnace for use with propane gas.
11. See Table 1 Minimum clearance to combustible material
for all units for required clearances to combustible construction.
12. Maintain a 1” (25 mm) clearance from combustible materials
to supply air ductwork for a distance of 36” (914 mm) horizontally
from the furnace. See NFPA 90B or local code for further
requirements.
13. These furnaces SHALL NOT be installed directly on
carpeting, tile, or any other combustible material other than wood
flooring.
PERSONAL INJURY AND/OR PROPERTY DAMAGE HAZARD
Improper use or installation of this furnace may result in premature
furnace component failure. This gas furnace may be used for heating
buildings under construction provided that.
The furnace is permanently installed with all electrical wiring, piping,
venting and ducting installed according to these installation instructions.
A return air duct is provided, sealed to the furnace casing, and
terminated outside the space containing the furnace. This prevents a
negative pressure condition as created by the circulating air blower,
causing a flame rollout and/or drawing combustion products into the
structure.
The furnace is controlled by a thermostat. It may not be “hot-wired” to
provide heat continuously to the structure without thermostatic control.
Clean outside air is provided for combustion. This is to minimize the
corrosive effects of adhesives, sealers and other construction materials.
It also prevents the entrainment of drywall dust into combustion air,
which can cause fouling and plugging of furnace components.
The temperature of the return air to the furnace is maintained between
60°F (16 °C) and 80°F (27 °C), with no evening setback or shutdown.
The use of the furnace while the structure is under construction is
deemed to be intermittent operation per our installation instructions.
The air temperature rise is within the rated rise range on the furnace
rating plate, and the gas input rate has been set to the nameplate value.
The filters used to clean the circulating air during the construction
process must be either changed or thoroughly cleaned prior to
occupancy.
The furnace, ductwork and filters are cleaned as necessary to remove
drywall dust and construction debris from all HVAC system components
after construction is completed.
Frozen and burst water pipe hazard
Failure to protect against the risk of freezing may result in property
damage. Special precautions MUST be made if installing furnace in an
area which may drop below freezing. This can cause improper operation
or damage to equipment. If furnace environment has the potential of
freezing, the drain trap and drain line must be protected
FIRE, INJURY OR DEATH HAZARD
Failure to follow this warning could result in personal injury, death
and/or property damage.
When the furnace is installed in a residential garage, the burners and
ignitions sources must be located at leat 18” (457 mm) above the floor.
The furnace must be located or protected to avoid damage by vehicles.
When the furnace is installed in a public garage, airplane hangar, or
other building having a hazardous atmosphere, the furnace must be
installed in accordance with the NFPA 54/ANSI Z223.1-2009 or
CAN/CSA B149.2-2010 (Figure 2 Installation in a garage)
Do not install the furnace on its back or hang furnace with control
compartment facing downward. Safety control operation will be
adversely affected. Never connect return air duct to the back of the
furnace. (Figure 3 Prohibited installation)
Failure to follow this caution may result in burst water pipes and/or
property damage. If a condensate pump is installed, a plugged
condensate drain or a failed pump may cause the furnace to shut down.
Do not leave the home unattended during freezing weather without
turning off water supply and draining water pipes or otherwise
protecting against the risk of frozen pipes.
Ensure all condensate drain connections are secured and liquid tight.
Use the furnished tube clamps and verify tightness
