MAIN BURNER FLAME CHARACTERISTICS
SR-10TW, SR-18TW and SR-30TW Main Burner Flame. See
Figure 12. The main burner flame will have a red-orange glow over
the surface of the ceramic plaques. A few small, hairline cracks may
form over the surface of the ceramic plaques or at the edges of the
ceramic plaques where they have been cemented into position on
the burner assembly frame. These small, hairline cracks will not
affect the operation or performance of the ceramic plaques. Only,
when large cracks develop, with blue flames escaping from the large
cracks, should you contact your QUALIFIeD SeRVICe PeRSON.
A red-orange haze that is visible on the ceramic plaques is acceptable.
A blue flame that rolls out at the top of the ceramic plaques indicates
an accumulation of dust, lint or spider webs inside the casing assembly
and main burner assembly. Use the following procedure to inspect
the casing assembly and main burner assembly.
1.
Turn OFF gas supply to the heater.
2.
Turn OFF electric supply to the heater if optional blower is
installed in heater.
3.
Remove lower louver from casing assembly ( 2 screws).
4.
Remove reflector from casing assembly (2 screws).
5.
Inspect interior of casing assembly for accumulation of dust, lint
or spider webs. If necessary, clean interior of casing assembly
with a vacuum cleaner or apply air pressure. Do not damage any
components within casing assembly when you are cleaning.
6.
Remove pilot bracket from main burner assembly (2 screws).
7.
Pivot pilot bracket with attached pilot away from main burner
assembly (do not damage pilot tubing).
8.
Inspect main burner orifice(s) through the rectangular opening(s)
in the venturi (throat) of the main burner(s). Dust, lint and spider
webs can accumulate on top of the main burner orifice(s). If
necessary, clean main burner orifice(s) with a vacuum cleaner
or apply air pressure. To thoroughly clean the main burner
orifice(s) proceed to Step 9.
IMPORTANT SOOT PREVENTION STEPS
SOOT MAY BE CREATED IF THE FOLLOWING DIRECTIONS ARE NOT FOLLOWED
A vent-free heater draws room air to support combustion. Lightweight
particles suspended in the air – including dust, carpet fibers, candle
or tobacco smoke, and pet hair – will be drawn toward the heater.
These can lead to soot build-up on the heater, and even walls of
the room. To prevent malfunctions and sooting, have your dealer
inspect and clean each year – before the heating season. If you
have pets or excessive dust, more frequent cleaning may be
necessary. See main burner flame characteristics section in this
manual.
1.
ensure burner, venturi, and air shutter are free of dirt, lint,
animal hair (i.e. cat and dog) or anything that may block the
needed air flow.
2.
Do not use scented air fresheners or candles while the
heater is in operation. They produce residue which may
cause soot.
3.
Annual inspection and cleaning by your dealer or a qualified
service technician is recommended to prevent malfunction
and/or sooting.

9.
Disconnect supply tubing from orifice holder(s).
10. Remove orifice holder from venturi of main burner assembly
(1 screw for each orifice holder).
11. Remove main burner orifice from orifice holder.
12. Apply air pressure through main burner orifice and orifice holder
to remove dust, lint or spider webs.
13. Apply air pressure into ceramic plaque(s) to remove dust, lint
or spider webs.
14. As parts are being replaced in reverse order, check for gas
leaks at all gas connections before lower louver is replaced
onto casing assembly.
SR-30T SHOWN
Do not allow fans to blow directly into or at the fireplace.
Avoid any drafts that alter burner flame patterns. Avoid any
drafts that alter burner flame patterns. Pay particular atten-
tion to ceiling fans and exhaust fans.
