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 7.
