GAS LINE HOOK-UP

WARNING: Gas line hook-up should be done by your gas supplier or a qualified service person.

WARNING: Before you proceed, make sure your gas supply is OFF.

An equipment shutoff valve has been included in the fireplace's gas supply system. However, consider installing an extra shutoff valve outside the appliance’s enclosure (check local codes), where it can be accessed more conveniently with a key through a wall as shown in Figure 12.

In conformance with local codes, route a 1/2" NPT gas line towards the appliance coming in from either the left or right side of the fireplace (see Figure 13).

Install a sediment trap between the incoming gas line and the gas control box. (see Figure 14). The sediment trap should extend down a minimum of 3" (7.62 cm) beyond the center of the pipe.

When routing gas line through conduit sleeve, make sure to repack insulation to fill gaps between gas line and conduit sleeve. Com- pounds 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 the flexible gas line. Secure tightly with a wrench but do not over-tighten.

WARNING: All gas piping and connections must be tested for leaks after the installation is completed.

Never use an open flame to check for a leak. After ensuring that the gas valve is open apply commercial leak detection fluid to all gas joints. Bubbles forming show a leak. Correct all leaks at once.

Do not operate any appliance if a leak is detected.

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" (.95 cm) to 1/2" (1.27 cm) from the pilot flame as shown in Figure 15.
