GAS SUPPLY TESTING

Note: This section is intended as a guide for qualified service technicians installing gas to the appliance.

CAUTION: Do not connect appliance before pressure test- ing gas piping. Damage to the gas valve may result and an un- safe condition may be caused.

The millivolt system with a manual HI/LO applies only to the VDDVF36STN/STP and VDDVF36PN/PP models. The gas control valve is secured underneath the firebox with two brackets fastened to the firebox bottom. Two pressure taps are provided on the gas control valve for a pressure gauge connec- tion (see Figure 40).

INSTALLING LOG SET

Before proceeding, make sure the gas con- trol valve is in the “OFF” position. Logs have been packaged separately to prevent damage to glass or refractory.

1.Remove top and bottom louvers by si- multaneously pulling both top end spring latches towards the center of the appliance until they are disengaged from locating holes. Repeat for bottom end spring latches and pull outward. Reverse procedure to install louvers back.

2.Remove the screen rod by sliding spring clip on one end toward the cen- ter. Slide rod into screen rod hole until other end of rod is free. Remove rod.

3.To open the glass door, open the pairs of latches located on the top and bottom of the firebox (see Figure 41). Note: Use caution when opening these latches.

4.Carefully open the door. The glass door is mounted to the firebox with 5 screws.

5.To remove the logs from the shrink wrap, carefully cut the plastic around the perimeter of the log. Do not try to remove the logs from the package with- out first cutting the plastic.
