GAS LINE HOOK-UP
WARNING: Gas line hookup
should be done by your gas sup-
plier or a qualified service person.
WARNING: Before you pro-
ceed, make sure your gas supply
is OFF.
A manual shut-off valve has been included
in the appliance's gas supply system. You
may consider installing an extra gas shut-off
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 towards the appliance coming
in from any of the 3 directions 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).
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 shut-off valve. It must
extend down three (3) inches beyond the cen-
ter of the pipe. Prepare incoming black iron
gas line with teflon tape or pipe joint com-
pound (Check with local building codes).

CAUTION: Compounds used
on threaded joints of gas piping
shall be resistant to the action of
Liquefied Petroleum (LP or pro-
pane), and should be applied
lightly to ensure excess sealant
does not enter the gas line.
WARNING: All gas piping
and connections must be tested
for leaks after the installation is
completed.
After ensuring that the gas valve
is on, apply a soap and water
solution to all connections and
joints. If bubbles appear, leaks
can be detected and corrected.
Do not use an open flame for leak
testing and do not operate any
appliance if a leak is detected.
Complete your gas installation by connect-
ing incoming gas line with flexible gas line.
Secure tightly with wrench but Do NOT
Overtighten.
