Proper Burner Flame; Maintenance - COZY VC201A-H Installation And Operating Instructions Manual

CAUTION: There may be momentary and spasmodic
orange flashes in the flame. This is caused by the burning
of air borne dust particles and is not to be confused with
the yellow tipping which is a stable or permanent situation
when there is insufficient primary air.

CLEANING: To clean the front casing of your heater, it is
only necessary to use a soft cloth. Light dust can be removed
in this way. To obtain a polish or gloss, use a little light
machine oil on the cloth. Do not use metal polish or cleaning
solution. The burner ports should be kept free from lint and
dust.
CLEANING OF COMBUSTION CHAMBER
The combustion chamber of your console heater should
never need to be cleaned if proper burner adjustment and
gas pressures are maintained. However, if an unusual
circumstance should occur, the following procedure should
be followed in cleaning your combustion chamber.
1. Turn off gas supply to heater at manual valve in
supply line to heater.
2. Disconnect heater at ground joint union ahead of
main gas valve.
3. Remove main control and orifice assembly.
4. Remove burner.
5. Remove combustion chamber.
6. Using a scraper, scrape inside of a primary
combustion chamber. This should be area of
heaviest accumulation of carbon.
7. Remove plug bottom located in bottom rear of
second combustion chamber. Using a bottlebrush,
clean inside of this chamber. Shake residue out the
clean-out hole.
8. Clean the rear chamber by using bottlebrush
through the vent tube openings.
9. Replace combustion chamber, burner and control.
Check all gas piping for leaks before lighting heater.
Repair service should be performed by qualified persons.
The heater should be inspected before initial use. An annual
cleaning of control compartment and safety performance
check should be made by a qualified service person. More
frequent cleaning may be required when exposed to the
excessive lint conditions due to carpeting and bedding
material, etc. It is imperative that the control compartment,
burners, and circulating air passageways of the heater be
kept clean. Any safety screen, casing top, or guard removed
for servicing the heater must be replaced prior to operating
heater.
If the venting system is not maintained in proper operating
condition, the vent safety shutoff will not allow heater to
operate. Periodic examination of the entire venting system
as a routine part of the safety performance check is
recommended on an annual basis.
It is advised that the pilot and main burner flames be checked
at least twice during the heating season for any changes in
flame characteristics. See Figure 2 and Figure 3.
