A. Always shut off the gas to the vent-free gas log set while performing service work.
B. Allow the vent-free gas log set to cool before servicing.
C. Installation and repair must be done by an NFI Certifi ed or other qualifi ed service person. The gas
log set should be inspected regularly to prevent burner shutdown, sooting, odors, etc. This unit must be
cleaned at least annually by a professional service person, with the correct tools to service this unit, to check
for clean-burning operation and proper ODS pilot appearance. More frequent cleaning may be required.
Excessive lint can build up on this unit from carpeting, bedding material, pet hairs, or other particles in the
air. It is critical that all control components, burners, and circulating air passageways be kept clean and
free of all obstructions. The ODS pilot assembly is especially sensitive to a dirty environment and will not
function properly if dirty.
Make certain all air openings are clean and free of obstructions, including:
1. The two (2) air intake openings on the ODS pilot
assembly (Fig. 23-2).
2. The ODS pilot opening (Fig. 23-2).
3. The air shutters - both of the ember burners and the
top burner for propane and natural gas (Fig. 23-3).
WARNING: Failure to keep the primary air openings of
the burner(s) clean may result in sooting and
property damage.
4. All of the ports on the carry-over tube (Fig. 23-2).
5. All of the ports on both the front/bottom burner and
the rear/top burner (Fig. 23-2).
D. Any safety screen or guard removed for servicing must
be replaced prior to operating this gas log set.
Only limited cleaning will be required under normal use of
the heater gas log set.
TO CLEAN THE LOG SET
1. Remove the logs. Use a vacuum cleaner to remove loose particles from all surfaces of the logs. Do not use
cleaning fl uids to clean the log or any other part of the log set.
2. Dust the grate, the base of the assembly, and the burners.
3. Replace the logs as instructed in the section entitled GLOWING EMBER AND LOG PLACEMENT in this
manual.
If, after a period of use, the fl ames start to exhibit unusual shapes and behavior, or the burners fail to ignite
smoothly, the burner holes may require some cleaning. If this happens, it is preferable to contact the nearest
dealer to get the heater gas log set serviced.
Do not remove rating plate and/or warning tags. These labels are an integral safety and identifi cation
component of this appliance.
During periods of heavy use, inspect the vent-free gas log set frequently for evidence of sooting. If sooting is
present, discontinue use until the source of sooting is corrected.
