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 material (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).

INSTALLATION

Continued

DESA recommends that a black iron gas line be routed from the gas

source, through a sediment trap (shown in Figure 20), 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 21).

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).

Figure 21 - Connecting Flexible Gas Line to Millivolt Valve

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.

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.
