• Within 6 feet of any service regulator vent
outlet;
• Less than 12" above grade level or anticipat-
ed snow level;
• Within 12" of any door, window, or non-me-
chanical air supply inlet to any building;
• Within 12" of the combustion air inlet of any
other appliance;
• Underneath a veranda, porch or deck, unless
(a) the veranda, porch or deck is fully open
on a minimum of two sides beneath the floor,
and (b) the distance between the top of the
vent termination and the underside of the ve-
randa, porch or deck is greater than 12".
IN THE U.S.A.
In addition to the general guidelines, in the United
States, the non-direct vent exhaust shall be in-
stalled in accordance with the following:
• The clearance from the bottom of the termi-
nal to grade shall be 12".

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.
NON-DIRECT VENT INSTALLATION
(USING INDOOR COMBUSTION AIR)
Non-direct vent installations require only a vent
pipe. This may be desirable when using outdoor
combustion air is not practical.
• Provisions are not made for routing of com-
bustion air;
• The outdoor environment may contain con-
taminants undesirable for combustion.
DIRECT VENT INSTALLATION
(USING OUTDOOR COMBUSTION AIR)
The direct vent configuration is the preferred instal-
lation method. The primary advantages are:
• No special kit or modifications are required
for direct vent installations
The vent terminal should be located no fewer than
6 feet from an inside corner formed by two exterior
walls; a 10 foot distance is recommended.
Recommended clearance from overhangs is a min-
imum of 1 foot vertically for each foot horizontally
up to 6 feet.
FURNACE VENTING INSTALLATIONS
!
This furnace is certified as a Category IV Type
FSP Non-Direct and Direct Vent Furnace. When in-
stalled as a direct vent furnace, all combustion air
is supplied from the outdoors via the plastic piping
system. All components are field supplied except
for the adapter used to connect the piping to the
furnace.
The combustion air piping, like the exhaust piping,
must be air tight throughout the system. The adapter
joining the combustion air to the furnace is supplied
with a gasket to maintain the seal.

• The vent shall not terminate over public walk-
ways or over an area where condensate or
vapor could create a nuisance or hazard.
• The vent terminal shall be installed 4 feet be-
low, 4 feet horizontally from, or 1 foot above
any door, window, soffit, under eave vent or
gravity air inlet to the building.
• The vent terminal shall have a minimum hori-
zontal clearance of 3 feet from electric meters,
gas meters, regulators and relief equipment.
• Locate the vent terminal 3 feet above any
forced air inlet located within 10 feet. Any
fresh air or make-up air inlet, such as for a
dryer or furnace area is considered a forced
air inlet.
• Dedicated combustion air and vent piping
eliminates the need to use already heated air
for combustion purposes;
• The probability of corrosive contaminants be-
ing present in the combustion air is greatly
reduced;
• The direct vent configuration is unaffected by
any other appliances, exhaust fans, or other
devices that tend to create negative pressure
conditions while operating.
• No vents for combustion and ventilation air
are required in confined spaces
