WARNING
!
CARBON MONOXIDE POISONING HAZARD
Failure 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 shorten furnace life.
Refer to Combustion & Ventilation Air section, Contaminated
Combustion Air for combustion air evaluation and remedy.
CAUTION
!
FROZEN AND BURST PIPE HAZARD
Failure to follow this caution may result in property damage.
Special precautions MUST be made is installing furnace in
an area which may drop below freezing. This can cause
improper operation or damage to equipment.
environment has the potential of freezing, the drain trap and
drain line must be protected. The use of electric heat tape or
RV antifreeze is recommended for these installations. (See
"Condensate Trap Freeze Protection Section")
Do NOT operate furnace in a corrosive atmosphere
containing chlorine, fluorine or any other damaging
chemicals. Refer to Combustion & Ventilation Air section,
Contaminated Combustion Air.
Installation Requirements
WARNING
!
CARBON MONOXIDE POISONING HAZARD
Failure to follow this warning could result in personal injury or
death.
Do NOT install this furnace in DOWNFLOW applications.
1. Install furnace level.
2. This furnace is NOT to be used for temporary heat of
buildings or structures under construction.
3. Install the vent pipes as short as practical. (See Gas Vent
Installation section).
4. Do NOT install furnace directly on carpeting, tile or other
combustible material other than wood flooring.
5. Maintain clearance for fire safety and servicing. A front
clearance of 24" (609.6 mm) required and 30" (762.0
mm)recommended for access to the burner, controls and
filter. See clearance requirements in Fig. 2.
6. Use a raised base if the floor is damp or wet at times.
7. Residential garage installations require:
S Burners and ignition sources installed at least 18" above the
floor.
S Furnace must be located or physically protected from possible
damage by a vehicle.
8. 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 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.
9. Local codes may require a drain pan under the entire fur-
nace and condensate trap when the furnace is installed in
attic application.
This furnace may be used for construction heat provided that all
the following conditions are met:
S 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.
S The furnace is controlled by a thermostat. It may not be "hot
wired" to provide heat continuously to the structure without
If furnace
thermostatic control.
S 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.
S 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.
S The air temperature rise is within the rated rise range on the
furnace rating plate, and the firing rate has been set to the
rating plate value.
S The filters used to clean the circulating air during the
construction process must be either changed or thoroughly
cleaned prior to occupancy.
S 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.
S After construction is complete, verify furnace operating
conditions including ignition, input rate, temperature rise and
venting according to these instructions.
Knockouts
CUT HAZARD
Failure to follow this caution may result in personal injury.
Sheet metal parts may have sharp edges or burrs. Use care
and wear appropriate clothing, safety glasses and gloves
when handling parts and servicing furnaces.
Use a hammer and screwdriver to strike a sharp blow (See Fig. 3)
directly to the knockout tie points or use a hammer in the upper
left corner of the desired knockout. Remove any burrs and sharp
edges.
