Installer:
Ax all manuals
adjacent to the unit.
As a professional installer you have an obligation to know
the product better than the customer. This includes all
safety precautions and related items.
Prior to actual installation, thoroughly familiarize yourself
with this Instruction Manual. Pay special attention to all
safety warnings. Often during installation or repair it is
possible to place yourself in a position which is more
hazardous than when the unit is in operation.
Remember, it is your responsibility to install the product
safely and to know it well enough to be able to instruct a
customer in its safe use.
Safety is a matter of common sense...a matter of thinking
safety practices...follow them.
The precautions listed in this Installation Manual are
intended as supplemental to existing practices. However,
the content of this manual, the precautions listed here take
precedence.

Use the following precautions during furnace installation
and servicing to protect the integrated control module
from damage. By putting the furnace, the control, and the
person at the same electrostatic potential, these steps
will help avoid exposing the integrated control module to

to the control prior to discharging your body’s
electrostatic charge to ground.
2. Firmly touch a clean, unpainted, metal surface of the
furnaces near the control. Any tools held in a person’s
hand during grounding will be discharged.
3. Service integrated control module or connecting
wiring following the discharge process in step 2.
Use caution not to recharge your body with static

Products of combustion must always be vented outside. A
vent pipe must never terminate in an attic, crawl space, or
any other part of a dwelling. Follow the vent pipe & intake
pipe termination requirements listed below as well as all
applicable local, State and National codes.
All terminations (vent and/or intake) must be located at
least 12” above ground level or the anticipated snow level.
All vent terminations (non-direct and direct vent) must
terminate at least 3 feet above any forced air inlet located
within 10 feet.
The vent termination of a non-direct vent application must
terminate at least 4 feet below, 4 feet horizontally from, or
1 foot above any door, window, or gravity air inlet into any
building.
The vent termination of a direct vent application must
gases may enter a building (door, window, or gravity air
inlet).
The vent termination of vent pipe run vertically through a
roof must terminate at least 12” above the roof line (or the
anticipated snow level) and be at least 12” from any vertical
wall (including any anticipated snow build up).
A vent termination shall not terminate over public walkways
or over an area where condensate or vapor could create a
nuisance or hazard or could be detrimental to the operation
of regulators, relief valves, or other equipment.
The combustion air intake termination of a direct vent
application should not terminate in an area which is
frequently dusty or dirty.
Vent & combustion air pipes may terminate vertically
through a roof, or horizontally through an outside wall. The
combustion air intake and vent pipe terminations must
be in the same atmospheric pressure zone. Vertical vent
pipe terminations should be as shown in Figure 14. The
penetration of pipes through the roof must be sealed water
plumbing vent.
Horizontal vent pipe terminations should be as shown in
the wall and prohibit damage to piping connections, a
coupling should be installed on either side of the wall and
solvent cemented to a length of pipe connecting the two
couplings. The length of pipe should be the wall thickness
inside and outside of the wall. The wall penetration should
be sealed with silicone caulking material.

This kit is to be used with 2” or 3” direct vent systems. The
vent kit must terminate outside the structure and may be
installed with the intake and exhaust pipes located side-
by-side or with one pipe above the other. These kits are
NOT intended for use with single pipe (non-direct vent)
installations.
A condensing gas furnace achieves its high level
combustion to the point where condensation takes place.
The condensate must be collected in the furnace drain trap
and routed to an appropriate drain location in compliance
with local and national codes.
Follow the bullets listed below when installing the drain
concerning furnace drain trap installation and drain hose
hook ups.
• The drain trap supplied with the furnace must be
used.
• The drain trap must be primed at time of installation.
• The drain line between furnace and drain location
must meet local and nation codes.
• The drain line between furnace and drain location
the drain.
•
the drain trap supplied with the furnace.
• If the drain line is routed through an area which may
see temperatures near or below freezing, precautions
must be taken to prevent condensate from freezing
within the drain line.
• If an air conditioning coil is installed with the furnace,
a common drain may be used. An open tee must be
installed in the drain line, near the cooling coil, to
relieve positive air pressure from the coil’s plenum.
This is necessary to prohibit any interference with the
function of the furnace’s drain trap.

All furnace models come with a factory installed drain trap.
For vertical installations, the trap will remain in the factory
position. All furnace models installed horizontally require
the trap to be relocated. Many drain hoses have a built-in
grommet which will provide a cabinet seal when installed.

must be primed before initial furnace start up. When
supplied furnace drain, it must be vented. An open tee
must be installed at a height no higher than the bottom
of the furnace collector box to prevent air conditioning
condensate from backing up into the furnace, if the
common drain was blocked.
The trap and factory installed hoses remain as shipped.
The furnace drain may exit either the right or left side of the
furnace cabinet. Both sides of the cabinet have two .875”
diameter holes which can be used interchangeably for
drain and low voltage wiring purposes. If a higher drain exit
is needed, a .875” diameter hole may be added in the area
shown in Figure 24. Any unused cabinet opening must be

the wiring diagram for wire routings. If any of the original
wire as supplied with the furnace must be replaced, it must
be replaced with wiring material having a temperature
rating of at least 105°C. Any replacement wiring must be a
copper conductor.
Before proceeding with electrical connections, ensure
that the supply voltage, frequency, and phase correspond
the furnace must be NEC Class 1, and must comply with
all applicable codes. The furnace must be electrically
grounded in accordance with local codes or, in their
absence, with the latest edition of The National Electric
Code, ANSI NFPA 70.
Use a separate fused branch electrical circuit containing
properly sized wire, and fuse or circuit breaker. The fuse
or circuit breaker must be sized in accordance with the
rating plate. An electrical disconnect must be provided at
the furnace location.
Connect hot, neutral, and ground wires as shown in the
wiring diagram located on the unit’s blower door. Metal
conduit is not considered a substitute for an actual ground
wire to the unit. For direct vent applications, the cabinet
opening to the junction box must be sealed air tight using
either an UL approved bushing such as Heyco Liquid
Tight or by applying non-reactive UL approved sealant to
bushing.

through either the right or left side panel. The furnace is
the junction box located inside the burner compartment. To
make electrical connections through the opposite side of
the furnace, the junction box must be relocated to the other
side of the burner compartment prior to making electrical
connections. To relocate the junction box, follow the steps
shown in the Junction Box Relocation section.
