GAS LINE HOOK-UP
WARNING: Gas line hookup
should be done by your gas
supplier or a qualified service
person.
WARNING: Before you pro-
ceed, make sure your gas supply
is OFF.
A manual shutoff valve has been included in the
applianceʼs gas supply system. You may consider
installing an extra gas shutoff valve outside the
applianceʼs 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
firebox or sub-floor as shown in Figure 17.
CAUTION: Do not kink flex-
ible gas line.

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 flexible
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
teflon tape or pipe joint compound (Check with
local building codes).
