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, page 13).

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 shutoff valve. It must extend down three (3) inches beyond the center of the pipe. Prepare incoming black iron gas line with teflon tape or pipe joint compound (Check with local building codes).
