INSTALLING VENTED APPLICATIONS

The fireplace and gas logs function as a system. If the fireplace is spilling into the
room (check with a match or a smoke stick), reposition the damper clamp until a
positive draft is obtained by opening the damper. If negative pressure in home
prevents having a positive draft, contact your dealer for assistance.
PLACING AND SECURING APPLIANCE
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 A
RESTRICTIVE BARRIER" on page 10.
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.
2. Refer to Figure 14 for hole locations. After centering the grate correctly, mark the hole positions on the fireplace/firebox
floor. Drill two (2)
3. Anchor the grate to the fireplace/firebox floor using the screws provided. Refer to Figure 14.
Proper installation of the grate is essential to prevent any movement of the gas logs and controls during operation.
