Maintenance
Burner and Burner Compartment
It is important to keep the burner and the burner
compartment clean. At least once per year the logs and
lava rock/ember material should be removed and the
burner compartment vacuumed and wiped out. Remove
and replace the logs as per the instructions in this
manual.
Always handle the logs with care as they
are fragile and may also be hot if the
fireplace has been in use.
Fan Assembly
The fan unit requires periodic cleaning. At least once
per month in the operating season, open the lower
louvre panels and wipe or vacuum the area around the
fan to remove any build up of dust or lint.
Cleaning the Standing Pilot
Control System
The burner and control system consists of:
• main burner • pilot burner
• gas orifice • thermopile
• combination millivolt gas valve
Most of these components may require only an occa-
sional checkup and cleaning and some may require
adjustment. If repair is necessary, it should be per-
formed by a qualified technician.
In order to properly clean the burner and pilot assembly,
turn off the gas to the unit, remove the window frame
panel and logs exposing the burner and pilot assembly.
Clean all foreign materials from the top of the burner.
Check to make sure that burner parts are clean.
Visually inspect pilot. Brush or blow away any dust or
lint accumulation. If pilot orifice is plugged, disassembly
may be required to remove any foreign material from
the orifice or tubing.
To obtain proper operation, it is imperative that the pilot
and burner's flame characteristics are steady, not lifting
or floating.
Typically, the top 1/8" of the thermopile should be
engulfed in the pilot flame. (Page 13, Fig. 24)
Brass Cleaning
Clean the brass trim with a soft clean cloth, slightly
dampened with lemon oil and buff with a soft dry cloth.
Do not use brass polish or household cleaners as these
products will damage the trim. Lemon oil can be
obtained at supermarkets or hardware stores.
