WARNING: Before you pro-
ceed, make sure your gas supply
is OFF.
The appliance and it’s individual shutoff valve
must be disconnected from the gas supply
piping system during any pressure testing of
that system at test pressures in excess of 1/2
psig (3.5 kPa).
The appliance must be isolated from the gas
supply piping system by closing its individual
equipment shutoff valve during any pressure
testing of gas supply piping system at test pres
-
sures equal to or less than 1/2 psig (3.5 kPa).
An equipment 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 15.
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.16.

DESA Heating, LLC recommends that a black
iron gas line be routed from the gas source,
through a sediment trap (shown in Figure 17,
page 13) and into appliance. Once connected
through appliance, a flexible gas line may be
used for ease of installation to gas control
valve (see Figure 18, page 13).
Before connecting black iron gas line to inside
of appliance a sediment trap must be included
outside appliance between gas line and gas
shutoff valve. It must extend down 3" beyond

CAUTION: Compounds used
on threaded joints of gas piping
shall be resistant to the action
of Liquefied Petroleum (LP or
propane) 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 commercial leak
detection solution to all con-
nections 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.
