VENT TERMINATION CLEARANCES
The final position of your fireplace depends on the location of the
vent termination in relation to the clearances that must be observed
as shown in Figure 5 on page 5.
The vent system serves as the “chimney” as well as the combustion
air supply (air intake). The horizontal run must have a rise of 1/4"
(.6 cm) for every 12" (30.48 cm) of horizontal run towards the
termination. The maximum horizontal run depends on the vertical
rise from the fireplace adapter collar to the vent termination (see
table below).
WARNING: Horizontal sections of this vent sys-
tem require a minimum clearance of 2" from the top
of the pipe and 1" minimum to the sides and bottom.
Vertical sections of this system require a minimum
of 1" clearance to combustible materials on all sides
of the pipe.

WARNING: Never allow the vent to run downward
as this may cause excessive temperatures which
could cause a fire.

FRAMING
Once the final location has been determined, observing height clear-
ances for vent termination, you may construct framing using dimen-
sions shown in Figures 3 and 4, depending on your installation.
If the appliance is to be installed directly on carpeting, tile (other
than ceramic), or any combustible material other than wood floor-
ing, the appliance must be installed on a metal or wood panel
extending the full width and depth of the appliance.
