Electronic Appliances -
To light electronic appliances refer to the
detailed lighting instructions found on Page
18 of these instructions. Electronic appliance
lighting instructions may also be found on the
pull out lighting instruction labels attached to
the gas control valve.
3. Keep the lower control compartment clean
by vacuuming or brushing at least twice a
year. More frequent cleaning may be required
due to excessive lint from carpeting, bedding
materials, pet hair, etc. It is very important
that the control compartments, burners
and circulating air passageways of the
appliance are kept clean.
4. Always turn off gas to the pilot (millivolt
appliances) and let the appliance cool down
before cleaning. Before re-lighting, refer

free from combustible materials, gasoline
and other fl ammable liquids.
6. Remember, Millivolt appliances have a continu-
ous burning pilot fl ame. Exercise caution when
using products with combustible vapors.

lighting instructions in this manual. Instruc-
tions are also found on pull-out panels
located below the glass door in the control

thoroughly inspected before initial use and at
least annually by a qualifi ed service technician
(inspection should include ensuring that exhaust
or intake passages are unobstructed and vent
components are properly assembled and not
damaged). If the venting system is disassembled
for any reason, a qualifi ed service technician
should follow vent installation instructions for
proper reassembly and proper sealing of the
venting system components. However, more
frequent periodic inspections and cleanings
should be performed by the homeowner.
