GAS LINE HOOK-UP
WARNING: Gas line hookup should be done by your gas sup- plier or a qualified service person.
WARNING: Before you pro- ceed, make sure your gas supply is OFF.
An equipment shutoff valve has been in- cluded in the appliance’s gas supply system. You may consider installing an extra gas shutoff valve outside the appliance’s enclo- sure (check with local codes) where it can be accessed more conveniently with a key through a wall as shown in Figure 14.
In conformance with local codes, route a 1/2” NPT gas line towards the appliance coming in from any of the 3 directions shown in Figure 15.

CAUTION: Do not kink flex- ible gas line.
DESA recommends that a black iron gas line be routed from the gas source, through a sediment trap (shown in Figure 16), 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 17).
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 equipment 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 pro- pane), 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 soap and water 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 connect- ing incoming gas line with flexible gas line. Secure tightly with wrench but Do NOT
Overtighten.
