INLET
WARNING
READ AND FOLLOW ALL INSTRUCTIONS
IN THIS SECTION. FAILURE TO PROPERLY
VENT THIS FURNACE CAN CAUSE CARBON
MONOXIDE POISONING OR AN EXPLOSION
OR FIRE RESULTING IN PROPERTY DAM-
AGE, PERSONAL INJURY OR LOSS OF LIFE.
NOTE:
Combustion air intake and exhaust termination
should be inspected periodically to ensure they are clear of
obstructions. i.e. vegetation, debris, snow, etc.
NOTE:
Accumulation of snow around the combustion air
intake and exhaust termination may have negative effects
on appliance operation and/or performance. Snow accu-
mulation should be considered when locating combustion
air intake and exhaust terminations.
Venting may be vertical or horizontal.
Minimum vent length - 25 total equivalent feet.
(See Venting Table)
Horizontal piping must slope back towards
the furnace at a minimum rate of ¼” to the
foot, so that condensate drains towards the
furnace.
Horizontal runs must be supported at least ev-
ery 3 feet. Horizontal sections must not dip or
sag.
All vent runs through unconditioned space
where freezing might occur should be insulated
with 1” thick, medium density, foil-faced Fiber-
glass insulation. An equivalent “arm-a-flex” or
“rub-a-tex” may also be used as long as there is
no heat tape applied to the vent pipe. For hori-
zontal runs where water may collect, wrap the
vent pipe with self regulating 3 or 5 watt heat
tape. The heat tape must be CSA, UL, or ULC
listed and installed per the manufacturer’s in-
structions.
DO NOT COMMON VENT WITH ANY OTH-
ER APPLIANCE.
If venting vertically, do not vent up a chimney
serving another appliance or install in a chase
with a metal or high temperature plastic pipe
from another gas or fuel burning appliance
unless the required clearances to combusti-
bles can be maintained between the furnace
venting system and other pipes.

IMPORTANT:
The outdoor grilles must be
installed in a location where they will not be
obstructed in any manner.
CONNECTION TO FURNACE
NON-DIRECT VENT
When using indoor air or the non-direct vent config-
uration, the combustion air inlet to the furnace must
be protected from blockage. Use a double elbow
arrangement if supplying combustion air through
the top, or a downward pointing single elbow if sup-
plying combustion air through the side.
(Figure 7)
11 - VENTING GUIDELINES
CAUTION
Failure to follow all venting guidelines may
result in erratic furnace operation, freeze-up
of the exhaust air piping, or sooting of the
furnace.
