8.1.5

CONNECTION TO FURNACE NON-DIRECT VENT

When using indoor air or the non-direct vent confi guration,
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 supplying
combustion air through the side. (Figure 7)

9.0 VENTING GUIDELINES

FAILURE TO FOLLOW ALL VENTING GUIDELINES MAY RESULT IN ERRATIC FURNACE
OPERATION, FREEZE-UP OF THE EXHAUST AIR PIPING, OR SOOTING OF THE FURNACE.
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
NOTE
• Combustion air intake and exhaust termination should be inspected periodically to ensure they are clear of
obstructions. i.e. vegetation, debris, snow, etc.
• Accumulation of snow around the combustion air intake and exhaust termination may have negative effects
on appliance operation and/or performance. Snow accumulation should be considered when locating
combustion air intake and exhaust terminations.
• Venting may be vertical or horizontal.
• Minimum vent length - 15 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 every 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 Fiberglass insulation. An equivalent "arm-a-fl ex" or "rub-a-tex" may also be used as long as there
is no heat tape applied to the vent pipe. For horizontal 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
instructions.
• DO NOT COMMON VENT WITH ANY OTHER 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
combustibles can be maintained between the furnace venting system and other pipes.
