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 appliance's gas supply system. You may
consider installing an extra gas shutoff valve
outside 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 appliance through hole
in left side of firebox or sub-floor as shown
in Figure 17.

DESA Heating, LLC recommends that a black
iron gas line be routed from the gas source,
through a sediment trap (shown in Figure 18)
and into appliance. Once connected through
appliance, a flexible gas line may be used for
ease of installation to gas control valve (see
Figure 19, 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
center of pipe. Prepare incoming black iron
gas line with teflon tape or pipe joint com-
pound (Check with local building codes).
