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
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. Anchor holes are located on the right and left sides of the unit. After centering the grate correctly, mark the hole positions
on the fireplace/firebox floor. Drill four (4)
3. Anchor the unit to the fireplace/firebox floor using the screws provided. Refer to Figure 12.
Proper installation of the grate is essential to prevent any movement of the gas logs and controls
during operation.
