should be done by your gas
supplier or a qualified service

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 18.
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 19.

DESA Heating, LLC recommends that a black
iron gas line be routed from the gas source,
through a sediment trap (see Figure 20) and
into appliance. Once connected through ap-
pliance, a flexible gas line may be used for
ease of installation to gas control valve (see
Figure 21, page 14).
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).
