This furnace is certified for use with Type “L” vent (maximum flue
gas temperature 575
o
F (302
o
C)). The flue pipe clearance knockout
in the front top or side panel should be removed. Install the flue

Pre-installation vent system inspection:
Before this furnace is installed, it is highly recommended that any
existing vent system be completely inspected.
For any chimney or vent, this should include the following:
a.
Inspection for any deterioration in the chimney or vent. If
deterioration is discovered, the chimney must be repaired or
the vent must be replaced;
b.
Inspection to ascertain that the vent system is clear and free of
obstructions. Any blockages must be removed before installing
this furnace;
c.
Cleaning the chimney or vent if previously used for venting a
solid fuel burning appliance or fireplace;
d.
Confirming that all unused chimney or vent connections are
properly sealed;
e.
Verification that the chimney is properly lined and sized per the
applicable codes. (Refer to list of codes on page 4.)
Masonry Chimney
This furnace can be vented into an existing masonry chimney. This
furnace must not be vented into a chimney servicing a solid fuel-
burning appliance. Before venting this furnace into a chimney, the
chimney must be checked for deterioration and repaired if
necessary. The chimney must be properly lined and sized per local
or national codes.
If the furnace is vented into a common chimney, the chimney must
be of sufficient area to accommodate the total flue products of all
appliances vented into the chimney.
The following requirements are provided to ensure a safe venting
system :
a.
Ensure that the chimney flue is clear of any dirt or debris;
b.
Ensure that the chimney is not servicing an open fireplace;
c.
Never reduce the pipe size below the outlet size of the furnace;
d.
All pipes should be supported using the proper clamps and/or
straps. These supports should be at least every 4 feet;
e.
All horizontal runs of pipe should have at least a ¼ inch per
foot of upward slope;
f.
All runs of pipe should be as short as possible, with as few
turns as possible;
g.
Seams should be tightly joined and checked for leaks;
h.
The flue pipe must not extend into the chimney but be flush
with the inside wall;
i.
The chimney must extend 3 feet above the highest point where
it passes through a roof of a building and at least 2 feet higher
than any portion of a building within a horizontal distance of 10
feet. It shall also be extended at lest 5 feet above the highest
connected equipment flue collar;
j.
Check local codes for any variances.
