PLACEMENT IN A FIREPLACE WITH A RESTRICTIVE BARRIER IMPORTANT INFORMATION FOR THE INSTALLATION OF THIS GAS LOG SET The following are guidelines for placing a gas log set in a fireplace that has a restrictive barrier along the bottom front open- ing of the fireplace. Some examples of barriers are glass/screen door frames and sunken/recessed fireplaces.

Page 8: Installation
INSTALLATION PLACING AND SECURING APPLIANCE You must secure the gas log heater to the fireplace floor. Properly securing the grate prevents movement of the entire unit when you adjust the controls. Grate movement could cause a gas leak. ASSEMBLY PROCEDURE 1. Center the gas log unit in the fireplace or firebox. Make certain the front feet of the grate sit inside the front edge of the fireplace or firebox. -
Page 9: Connecting The Gas
CONNECTING THE GAS A qualified gas appliance installer must connect the appliance to the gas supply. Consult all local codes before installation. Use new black iron pipe, steel pipe, copper tubing, or internally tinned copper tubing. Copper or internally tinned copper tubing can only be used according to the National Fuel Gas Code, section 2.6.3, providing gas meets sulfide limits, and where permitted by local codes. - Page 10 CONNECTING THE GAS The heater gas inlet connection is 3/8" NPT at the regulator, inlet on the right side facing the gas log. If a left side connection is required, the connecting pipe may be led under the rear of the gas logs or behind the grate for connection to the inlet. NOTE: The millivolt valve has an internal regulator, thus the incoming gas line connects directly to the valve. Test all gas joints from the gas meter to the appliance regulator for leaks using a gas analyzer or soap and water solution after completing connection. DO NOT USE AN OPEN FLAME. Check the gas pressure with the appliance burning. MANUAL CONTROL (Figure 6) The pressure regulator is preset and locked to discourage tampering. If the pressure is not as specified, replace with the correct part from the parts list in this manual.
