A manual shutoff valve has been included in the
appliance’s gas supply system. You may consider
installing an extra gas shutoff valve outside the
appliance’s enclosure (check with local codes)
where it can be accessed more conveniently with
a key through a wall as shown in Figure 16.
In conformance with local codes, route a 1/2" NPT
gas line to the appliance through hole in left side of
rebox or sub-oor as shown in Figure 17.

INSTALLATION
Continued
DESA recommends that a black iron gas line be
routed from the gas source, through a sediment
trap (shown in Figure 18) and into the appliance.
Once connected through the appliance, a exible
gas line may be used for ease of installation to gas
control valve (see Figure 19, page 13).
Before connecting the black iron gas line to the
inside of the appliance a sediment trap must be
included outside the appliance between the gas
line and the gas shutoff valve. It must extend
down three (3) inches beyond the center of the
pipe. Prepare incoming black iron gas line with
teon tape or pipe joint compound (Check with
local building codes).
