Maintenance

The appliance and venting system should be
thoroughly inspected before initial use and at
least annually by a qualified service techni-
cian. Proper maintenance and use will require
more frequent, less extensive inspections and
servicing by the homeowner.
Generally, annual inspections should be per-
formed by a qualified service technician. More
frequent periodic inspections and cleanings
should be performed by the homeowner. Any
discrepancies discovered by the homeowner
should result in a call to a qualified service
technician to effect the repair or correction.
Refer to the maintenance schedule for mainte-
nance tasks, procedures, periodicity and by
whom they should be performed.
IMPORTANT: TURN OFF GAS AND ANY
ELECTRICAL POWER BEFORE SERVICING
THE APPLIANCE.
