GBI25 SERIES B-VENT GAS FIRED FIREPLACE INSERT
H. MAINTENANCE INSTRUCTIONS
1. CLEANING THE BURNER AND
CONTROL COMPARTMENT
Keep the burner and control compartment clean by
using a clean, dry paint brush and vacuum at least
once a year. Always turn off the gas valve and the
switch before cleaning. (See Step 1 on the bottom of
page 14.)
2. VENTING SYSTEM INSPECTION
The appliance and venting system should be
inspected before use each season, and at least
annually, by a qualified service person to ensure that
the flow of combustion and ventilation air is not
obstructed.
3. CLEANING THE GLASS
a. It is recommended to wear gloves while handling
or removing the glass. DO NOT REMOVE THE
GLASS WHEN HOT.
b. To remove the glass frame for cleaning, follow
Step 3a. on page 7.
c. To clean the glass, use a nonabrasive, mild
cleaning solution. (For example, a glass cleaner
or an oven cleaner for stubborn film.) Apply an
adequate amount to the glass and wipe off with a
damp cloth. Be sure all cleaner is thoroughly
rinsed from the glass.
d. Never operate this appliance without the glass
properly secured in place or if the glass is broken.
e. In the event of glass breakage, follow glass
removal instructions. This will allow the removal
of all glass fragments 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 the
correct HTI part ordered direct or through your
local distributor. Never use substitute material.
Only ceramic glass may be used on this
appliance.
4. LOG CLEANING
Logs can be easily lifted out of position. Carbon
buildup can be removed with a vacuum cleaner.

5. CHECKING THE VENT SYSTEM
a. The venting system should be tested periodically
to ensure proper operation. This can be done
with a match while the appliance is operating.
Locate the draft tube between the glass frame
and top. See Figure 28.
b. Hold the match in front of the tube. If the flame
and smoke are drawn into the tube, the appliance
has good ventilation. If the flames and smoke
are forced away from the draft tube, this may
indicate a ventilation blockage or downdraft
resulting in exhaust spillage into your home. If
this occurs, turn off the appliance and do not burn
it until it has been inspected by a qualified service
person. See Figure 29.
