furnace and to replace any part of the control system and any
gas control which has been under water.
3.
Never obstruct the vent grilles, or any ducts that provide
air to the furnace. Air must be provided for proper combustion
and ventilation of flue gases.

FaiIure to follow this warning could result in
property damage.
Do not leave your home unattended for long periods
during freezing weather without turning off water
supply and draining water pipes or otherwise
protecting against the risk of frozen pipes and
resultant damage.

to resize the existing vent system to prevent
oversizing problems for the other remaining
appliances(s). See Venting and Combustion Air
Check in the Gas Vent Installation section of
this instruction.
Location and Clearances
If furnace is a replacement, it is usually best to install the furnace
where the old one was. Choose the location or evaluate the existing
location based upon the minimum clearance and furnace
dimensions (Figure 1).

CARBON MONOXIDE POISONING HAZARD.
FaiIure to follow this warning could result in
personal injury or death.
Do NOT operate furnace in a corrosive atmosphere
containing chlorine, fluorine or any other damaging
chemicals, which could harm the furnace and vent
system and permit spillage of combustion products
into an occupied space.
Refer to Combustion & Ventilation Air section,
Contaminated Combustion Air for combustion air
evaluation and remedy.
Installation Requirements
1. Install furnace level.
2.
This furnace is NOT to be used for temporary heat of buildings
or structures under construction.
3.
Install furnace as centralized as practical with respect to the
heat distribution system.

water pipes will not freeze. It is equipped with several safety devices
that are designed to turn the furnace off and prevent it from
restarting in the event of various potentially unsafe conditions.
If your furnace remains off for an extended time, the pipes in your
home could freeze and burst, resulting in serious water damage.
If the structure will be unattended during cold weather you should
take these precautions.
1.
Turn off the water supply to the structure and drain the water
lines if possible and add an antifreeze for potable water to drain
traps and toilet tanks. Open faucets in appropriate areas.
2.
Have someone check the structure frequently during cold
weather to make sure it is warm enough to prevent pipes from
freezing. Instruct them on a service agency to call to provide
service, if required.
3.
Install a reliable remote sensing device that will notify
somebody of freezing conditions within the home.
4.
Install the vent pipes as short as practical. (See Gas Vent
Installation section).
5.
Do NOT install furnace directly on carpeting, tile or other
combustible material other than wood flooring.
6.
Maintain clearance for fire safety and servicing. A front
clearance of 24" (610mm) is minimum for access to the burner,
controls and filter. See clearance requirements in Figure 1.
7.
Use a raised base if the floor is damp or wet at times.
8.
Residential garage installations require:
Burners and ignition sources installed at least 18" (457 mm)
•
above the floor.
Furnace must be located or physically protected from
•
possible damage by a vehicle.
9.
If the furnace is to be suspended from the floor joists in a
basement or a crawl space or the rafters in an attic, it is
necessary to use steel pipe straps or an angle iron frame to
attach the furnace. These straps should be attached to the
furnace bottom side with sheet metal screws and to the rafters
or joists with bolts. The preferred method is to use an angle iron
frame bolted to the rafters or joists.
10. This furnace may be used for construction heat provided that:
•
The furnace is permanently installed with all electrical wiring,
piping, venting, air filters 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 55° F (13° 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.
