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 t\_llowed 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 asselnbly.
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 chalnber. 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 perforlned by qualified persons.
The heater should be inspected before initial use. An annual
cleanin_ of control compartlnent and safety perforlnance
check should be made by a qualified service person. More
fiequent cleaning may be required when exposed to the
excessive lint conditions due to carpeting and beddin_
material, etc. It is imperative that the control compartlnent,
burners, and circulatin_ air passageways of the heater be
kept clean. Any safety screen, casing top, or guard removed
t\_r selwicin_ 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 pert\_rmance 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 tbr any changes in
flame characteristics. See Figure 2 and Figure 3.
