INSTALLATION

Continued

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 commercial leak detection solution to all con- nections 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 OVER- TIGHTEN.

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 22).

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 mate- rial (see Figure 23).

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 24, page 15).
