PREPARATION

FRAMING
1. Frame appliance enclosure as illustrated in Figures 7 and 8.
Note: If a wall covering is used to line the enclosure, then all
measurements must be from the surface of the covering.
2. Place the appliance into the framing and secure it.
Note: If appliance is to be raised above floor level, a platform
must be built to support the appliance.
3. Install the supply line to the appliance using a 1/2" NPT black
iron gas line terminating 2
pliance. The gas line must be installed through the lower left
side access point or alternate access hole in the bottom of the
appliance (see Figure 19, page 11).
4. Repack insulation around the gas line to cover any remaining
openings in the conduit sleeve. Prepare the incoming gas line
with teflon tape or pipe joint compound and hook-up incoming
gas line to the flexible gas line.
Note: If 1/2" NPT black iron pipe does not mate with fitting
at the end of flexible gas line, remove fitting and replace with
a 37 degree flare 3/4"-12, 1/2" NPT (female) fitting.
WARNING: When finishing appliance, do not overlap
combustible material onto the black front face. Brick,
tile or other noncombustible materials may be applied
to the face provided that any gap is between the mate-
rial used and the face is caulked with a noncombustible
caulking.
