Install a sediment trap between the incoming gas line and the gas control box (see figure 18). The sediment trap should extend down a minimum of 3 inches (76 mm) beyond the center of the pipe.

Figure 18

SEDIMENT TRAP

When routing gas line through conduit sleeve, make sure to repack insulation to fill gaps between gas line and conduit sleeve.

Compounds used on threaded joints of gas piping shall be resistant to the action of propane or natural gas. Compounds should be applied lightly to ensure excess sealant does not enter the gas line.

Complete your gas line installation by connecting the incoming gas line to flexible gas line. Secure tightly with a wrench but do not over-tighten.

CAUTION: 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 connections and joints. Bubbles forming show a leak. Correct all leaks at once. DO NOT USE AN OPEN FLAME FOR LEAK TESTING AND DO NOT OPERATE ANY APPLIANCE IF A LEAK IS DETECTED. LEAK TESTING SHOULD BE DONE BY A QUALIFIED SERVICE PERSON.

PILOT ADJUSTMENT

The pilot or electrode assembly is factory preset for the proper flame height. Alterations to these settings may have occurred during shipping and handling. If this is the case, some minor readjustments may be necessary and should be done by a qualified service technician. The proper settings for the thermopile height should be at a distance of 3/8” (10mm) to ½” (13mm) from the pilot flame as shown in figure 19.
