GC150 SERIES DIRECT VENT GAS APPLIANCE
Cleaning the burner and control compartment
Keep the burner and control compartment clean by brushing and
vacuuming at least once a year. Always turn off the gas valve and
the ON/OFF switch before cleaning.
Checking flame patterns
Visually check the flame of the burner periodically, making sure the
flames are steady; not lifting or floating. The flame color should be
blue with yellow tips. The ignitor (electronic) or thermopile (stand-
ing pilot) tips should be covered with flame. See Figures 41
through 44.
Venting system inspection
The appliance and venting system should be inspected before use,
and at least annually, by a qualified field service person, to ensure
that the flow of combustion and ventilation air is not obstructed.

Note: When cleaning the glass, NEVER use abrasive
materials. NEVER clean glass when hot. Keep pets
and children a safe distance away.
It is recommended to wear gloves while handling or removing
glass. DO NOT REMOVE GLASS WHEN HOT.
Clean glass after initial one hour burn. This is to remove any film
that develops from oils and log burn in time. After initial cleaning,
clean as needed.
To remove the glass for cleaning, follow Step 11 on page 16.
Handle glass panel with care to avoid striking or scratching it on
hard objects.
To clean the glass, use a non-abrasive automotive rubbing com-
pound and glass cleaner. Simply apply an adequate amount to
the glass and wipe off per manufacturers instructions. Contact
your local stove shop or fireplace accessaries store for further rec-
ommendations.
Never operate this appliance without the glass properly secured in
place or if the glass is broken.
In the event of glass breakage, follow glass removal instructions
to remove the top retaining strip. Remove lower retaining strip in
the same manner. This will allow the removal of all glass frag-
ments and sheet metal edge protection strips. Vacuum all
remaining glass pieces with a shop vac. (DO NOT VACUUM IF
PIECES ARE HOT.) Replace glass only with Heatilator part num-
ber 15573 ordered direct or through your local distributor. Never
use substitute material. Only fully tempered soda lime safety
glass or optional ceramic glass may be used on this appliance.
Log cleaning
Logs can be easily lifted out of position. Carbon build-up can be
removed with a vacuum cleaner.
To prevent the possibility of soot, we have provided your fireplace
with an adjustable air shutter. Your air shutter is provided in an
open position to ensure clean operation under normal situations.
In the even that soot is accumulating in your appliance, the air
shutter should be opened farther as shown in Figure 44. This can
be done with a screwdriver or a 1/4” wrench. Also, ensure logs
are positioned correctly to minimize flame contact with the logs.
