BEFORE FULLY INSTALLING THE APPLIANCE
Before installing in a solid fuel burning fireplace, the chimney
flue and firebox must be cleaned of soot, creosote, ashes and loose
paint by a qualified chimney cleaner.
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.
1. Center the gas log in the fireplace or firebox. The grates must
clear the fireplace or firebox screen.
2.
An anchor hole is provided in the two bottom side members
of the grate frame. After centering the grate correctly, mark
the hole positions on the fireplace/firebox floor. Drill two (2)
5/32" diameter holes approximately 1-1/2" deep for masonry
screws or 1/8" hole for sheet metal screws.
