MAIN BURNER FLAME CHARACTERISTICS

SR-6 Main Burner Flame (Figure 15)
The main burner flame will have a red-orange glow over the sur-
face of the ceramic plaque. The red-orange glow on the surface of
the ceramic plaque will have a pattern in the shape of a number
1. The perimeter of the ceramic plaque [approximately the outside
1/4"(6mm)] will not glow. 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.
SR-10, SR-18 and SR-30 Main Burner Flame (Figure 16)
The main burner flame will have a red-orange glow over the sur-
face 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 accept-
able. 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 as-
sembly.
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 burn-
er 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.
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.
