INSTALLING VENTED APPLICATIONS

PLACING AND SECURING APPLIANCE

WARNING

You must secure the gas log heater to the fireplace floor. If not, the entire unit may move when you adjust the controls. Movement of unit may cause shifting of the gas logs which leads to sooting and improper burning. Grate movement could cause a gas leak.

Special care is required if you are installing the unit into a sunken fireplace. You must raise the fireplace floor to allow access to gas log controls. This will insure adequate air flow and guard against sooting. Raise the fireplace floor using noncombustible materials, as described in Placement in a Fireplace with Restrictive Barrier on page 10.

ASSEMBLY PROCEDURE:

1.Center the gas log unit on the fireplace or firebox. Make certain the front of the burner sits inside the front edge of the fireplace or firebox.

2.Anchor holes are located on the right and left sides of the unit. After centering the burner correctly, mark the hole posi- tions on the fireplace/firebox floor. Drill two (2) 5/32" diameter holes approximately 11/2" deep.

3.Anchor the burner to the fireplace/firebox floor using the screws provided. See Figure 14.

Proper installation of the grate is essential to prevent any movement of the gas logs and controls during operation.
