Frozen Water Pipe Hazard
FROZEN AND BURST WATER PIPE HAZARD
FaiIure to protect against the risk of freezing could
result in property damage and/or personal injury.
Donotleaveyourhomeunattendedforlongperiods
during freezing weather without turning off water
supply and draining water pipes or otherwise
protecting against the risk of frozen pipes and
resultant damage.
!
WARNING
Yourfurnaceis designed solely to provideasafe and comfortable
living environment. The furnace is NOT designed to ensure that
water pipes will not freeze. It is equipped with several safety de-
vices that are designed to turn the furnace off and prevent it from
restarting in the event of various potentially unsafe conditions.
Ifyour furnace remains offfor an extended time, the pipes in your
home could freeze and burst, resulting in serious water damage.
If the structure will be unattended during coldweather you should
take these precautions.
1. Turnoffthewatersupplytothestructureanddrainthewater
lines if possible and add an antifreeze for potable water to
drain traps and toilet tanks. Open faucets in appropriate
areas.
-- or --
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.

CARBON MONOXIDE POISONING HAZARD.
Failure to properly vent this furnace or other
appliances could result in death, personal injury
and/or property damage.
If this furnace is replacing a previously common-
vented furnace, it may be necessary to resize the
existing vent system to prevent oversizing
problems for the other remaining appliances(s).

Vent Installation section of this instruction.

WARNING
Location and Clearances
If furnace is a replacement, it is usually best to install the furnace
wheretheoldone was. Choose the location orevaluate the exist-
ing location based upon the minimum clearance and furnace di-
mensions (Figure 1 or Figure 2 ).
CARBON MONOXIDE POISONING HAZARD.
Failure to follow safety warnings could result in
serious injury, death, or property damage.
Do NOT operate furnace in a corrosive
atmosphere containing chlorine, fluorine or any
other damaging chemicals which could harm the
furnace and vent syst em, and permit spillage of
combustion products into an occupied space.
Refer to 4. Combustion & Ventilation Air section,
Contaminated Combustion Air for combustion air
evaluation and remedy.

WARNING
Installation Requirements
1. Install furnace level.
2. ThisfurnaceisNOT tobeusedfortemporaryheatofbuildings
or structures under construction.
3. Install furnace as centralized as practical with respect to the
heat distribution system.
4. Install the vent pipes as short as practical. (See 5. Gas Vent
Installation section).
5. DoNOT installfurnacedirectlyoncarpeting, tile orothercom-
bustible material other than wood flooring.
6. Maintain clearance for fire safety and servicing. A front clear-
anceof30² is minimumfor access to theburner, controls and
filter. See clearance requirements in Figure 1 or Figure 2.
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 ² (457
mm) above the floor.
· Furnace must be located or physically protected from
possible damage by a vehicle.
9. Ifthefurnaceistobesuspendedfromthefloorjoistsinabase-

use s teel pipe straps or an angle iron frame to attach the fur-
nace. These s traps should be attached to the furnacebottom
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. Thisfurnacemaybeusedforconstruction heat providedthat:
· The furnace is permanently installed with all electrical
wiring,piping,ventingandductinginstalledaccordingto
these installation instructions. A return air duct is pro-
vided,sealed to thefurnace casing, and terminated out-
side the space containing the furnace. This prevents a
negativepressureconditionascreatedbythecirculating
air blower, causing a flame rollout and/or drawing com-
bustion products into the structure.
· The furnace i s c ontrolled 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
minimizethe corrosiveeffectsofadhesives, sealers and
otherconstructionmaterials. Italsopreventstheentrain-
mentofdrywalldustintocombustionair,whichcancause
fouling and plugging of furnace components.
· The temperature of the return air to the furnace is main-
tained between 55° F(13° C) and 80° F(27° C) , with no
evening setback or shutdown. The use of the furnace
whilethestructureisunderconstructionisdeemedtobe
intermittent operation per our installation instructions.
