If a wall covering is used to line the enclosure, then all mea-
surements 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 fl oor 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 2-5/16" above the bottom of the appliance. 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 16,

).
4. Repack insulation around the gas line to cover any remaining open-

tape or pipe joint compound and hook-up incoming gas line to the
fl exible gas line.
NOTE:
If 1/2" NPT black iron pipe does not mate with fi tting at the
end of fl exible gas line, remove fi tting and replace with a 37° fl are
3/4"-12, 1/2" NPT (female) fi tting.
