Pre-Installation Vent System Inspection
Before this furnace is installed, it is strongly recommended
that any existing vent system be completely inspected.
For any chimney or vent, this should include the following:
a. Inspection for any deterioration of 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 cleared
before installing this furnace;

Masonry Chimneys
This furnace can be vented into an existing masonry
chimney. It 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 and/or national codes.
If the furnace is vented into a common chimney, the chimney
must be of sufficient area to accommodate the total flue

straps. These supports should be installed at least
every 1.2 m (4');
e. All horizontal runs of pipe should have a slope of at
least 2 cm per 1 m (¼" per foot);
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 0.9 m (3') above the highest
point where it passes through a roof of a building and at
least 0.6 m (2') higher than any portion of a building
within a horizontal distance of 3 m (10'). It shall also be
extended at lest 1.5 m (5') above the highest connected
equipment flue collar;
