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 Figure19).
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).
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 commer- cial leak detection solution to all connections 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.
Complete your gas installation by connecting incoming gas line with flexible gas line. Secure tightly with wrench but DO NOT
OVERTIGHTEN.

EMBER AND PAN MATERIAL PLACEMENT
1.Open the bag(s) of vermiculite and fill the entire burner pan until the burner tube is completely covered (see Figure 20).
2.Smooth the pan material just even with edges of the burner pan.
3.Remove the ember material from the bag and flatten small amounts into quarter size pieces and lay on top of the surface of the pan material (see Figure 21).
4.Place just enough to cover the entire surface and leave about a 1/2 inch gap under the lower grate members to allow air to flow (see Figure 22).
