Vertical Venting
The combustion air intake pipe can be connected to the termination cap
(see Figure 6b) or it can terminate inside the chimney (see Figure 6a).
If combustion air intake pipe is terminated inside the chimney and not
connected to the actual termination cap the bottom opening of the chim-
ney (chimney throat) must be sealed around the vent pipes. Use a non
combustible seal-off plate (i.e. 22 gage sheet steel) or unfaced fiberglass
insulation (8 lb per square foot density minimum) to seal around the vent
pipes. Whichever “seal off” method is used must effectively seal the area
to prevent room air passage to the chimney of the fireplace. The insulation
may give off an odor during the first hour of operation.
NOTES:
The minimum vertical rise (exhaust vent) is 10 feet (3.05 M) and the
maximum vertical rise is 35 feet (10.67 M). These dimensions are
measured from the flue collar of the unit to the end of the vent pipe,
The fireplace and fireplace chimney must be clean and in good working
order and constructed of non-combustible materials. Inspect chimney
clean-outs for proper fit and seal.
See Table 5 for the minimum vertical termination height requirements.

Insert Leveling
At each front and rear corner of the insert is an adjustable leg provided
to level the insert should the hearth of the fireplace be uneven. To adjust
the legs in the rear, loosen the two 5/32” allen head screws, move the leg
to the desired height, and then tighten the screws. Repeat these steps
for each adjusting leg. To adjust the legs in the front use a 9/16” open
end wrench. See Figures 7 and 8.
NOTE: The rear leveling legs on each side of the gas fireplace insert unit
have 13/64” holes located in them for the purpose of fastening the rear
of the unit down in the fireplace (masonry or factory built fireplace).
Right front leveling leg. Use open end 9/16”
wrench to adjust height up or down
