Certain heater components could be damaged by scraping or brushing.
These components could malfunction and result in injury to personnel
(for example, fuel hoses could be damaged resulting in fuel leakage and
fire).
Scrape or brush. Use a scraping tool and wire brush to remove all hardened deposits of soot, resin, or
other foreign matter from the stack, lid assembly, solid fuel grate, and burner body components, inside
and out.
Do not scrape or brush any rubber or plastic parts, instruction or I.D. plates, fuel flow control valve
labeling or sightglass.
Clean under the fire ring of the burner assembly with a brush or dry rag. Carbon may build up under the
fire ring after a period of use.

assembly, etc.) with a cloth and mildly soapy water. Wipe all surfaces to remove any soot or other
residues. Wash interior of heater body, burner shell assembly, stack cap assembly, and stack assembly

On the inside and outside of the heater body, stack cap assembly, and stack assembly, scrape or wire
brush any dirt buildups which will not come off by washing.
Dry heater body and metal components with a dry rag. Wipe down all metal components with a rag
dampened with a light machine oil or WD-40 type product or they will rust.
