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.
4. Install the vent pipes as short as practical, and in
accordance to these instructions. (See Vent and
Combustion Air Piping section).
5. Maintain clearance for fire safety and servicing. A front
clearance of 24" (609.6mm) required and 30" (762mm)
recommended for access to the burner, controls and filter.
See clearance requirements in Figure 4.
6. Use a raised base for upflow furnace if the floor is damp or
wet at times.
7. For downflow installations, non combustible subbase must
be used under the furnace unless installation is on a non
combustible floor surface. This requirement applies even
when a coil box or cabinet is used.
8. For horizontal installations, line contact is permissible only
between lines formed by intersection of back and two sides
of furnace jacket, and building joists, studs or framing.
9. Residential garage installations require:
•
Burners and ignition sources installed at least 18"
(457.2mm) above the floor.
•
Located or physically protected from possible damage by
a vehicle.
10. Local codes may require a drain pan under the entire
furnace 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:
•
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.
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.
•
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.
•
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.
•
After construction is complete, verify furnace operating
conditions including ignition, input rate, temperature rise
and venting according to these instructions.

WARNING
!
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 shorten furnace life.
Refer to Combustion & Ventilation Air section,
Contaminated Combustion Air for combustion air
evaluation and remedy.
Furnace Installation Considerations
The installation of the furnace for a given application will dictate the
position of the furnace, the airflow, ductwork connections, vent and
combustion air piping. Consideration must be given to the
following:
Condensate Trap and Drain Lines
The supplied condensate trap must be attached to the furnace side
panel on either the left or right side. For horizontal installations, the
drain trap is vertically attached to the side panel below the furnace.
A minimum clearance of 6" (152.4mm) below the furnace is
required for the condensate trap. Downward slope of the
condensate drain line from the condensate trap to the drain
location must be provided. Adequate freeze protection of the drain
trap and the drain line must be provided. See "Condensate Drain
Trap" section for further details.
Leveling
Proper leveling of the furnace must be provided to insure proper
drainage of the condensate from the furnace. The furnace must be

for upflow and downflow installations or top to bottom for horizontal
installations.
Vent and Combustion Air Connections
For venting information literature, call 931.270.4100 with the
complete model and serial number of the furnace.
Special Venting Requirements for Installations in Canada
Installation in Canada must conform to the requirements of CSA
B149 code. Vent systems must be composed of pipe, fittings,
cements, and primers listed to ULC S636. The special vent
fittings and accessory concentric vent termination kits and
accessory external drain trap have been certified to ULC S636
for use with those IPEX PVC vent components which have
been certified to this standard.
cement must be of the same manufacturer as the vent system −
IPEX System 636, PVC/CPVC Primer, Purple Violet for Flue
Gas Venting and IPEX System 636
Gas Venting, rated Class IIA, 65 deg C. must be used with this
venting system − do not mix primers and cements from one
manufacturer with a vent system from a different manufacturer.
Follow the manufacturer's instructions in the use of primer and
cement and never use primer or cement beyond its expiration
date.
The safe operation, as defined by ULC S636, of the vent
system is based on following these installation instructions, the
vent system manufacturer's installation instructions, and proper
use of primer and cement. All fire stop and roof flashing used
with this system must be UL listed material. Acceptability under
Canadian standard CSA B149 is dependent upon full
compliance with all installation instructions.
standard, it is recommended that the vent system be checked
once a year by qualified service personnel.
The authority having jurisdiction (gas inspection authority,
municipal building department, fire department, etc) should be
consulted before installation to determine the need to obtain a
permit.
