FRAMING
Construct framing using dimensions shown if
Figures 6, 7 and 8. (Use the figure applicable to
your application.) Figure 6 shows the framing
dimensions prior to having the appliance in place.
Once the unit has been fitted, bring studs in against
nailing flanges located on the side of the appliance
making sure a 1" clearance is maintained as shown
in Figure 7.
If the fireplace is to be installed directly on carpet-
ing, tile (other than ceramic) or any combustible
material other than wood flooring the fireplace
must be installed upon a metal or wood panel
extending the full width and depth of the fireplace
(see Figure 8). The platform must be solid, flat and
fully supported.

VENT PIPE INSTALLATION
A 6", B-1 type gas vent pipe is a double-wall, vent-
ing system (not supplied) which must be installed
during rough framing of the appliance. Any B-1
type gas vent system may be used for proper vent-
ing as long as the vent system is installed per the
vent manufacturerʼs recommendations.
DESA supplies this appliance with a tapered starter
pipe for a snug fit. Slide B-1 type vent pipe over
this starter pipe until vent pipe is fully seated.
Secure this first section of B-vent pipe by strap-
ping the connector around the vent pipe and then
tightening the strap with any 1/8" nut and bolt (see
Figure 9). Note: Visually inspect for proper vent
connection by looking inside top of appliance. If
connection does not appear to be correct, contact
your local service technician.
