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).
