7. SERVICING GUIDE
Servicing of heater is essential for continued efficient operation. Servicing should be carried out
annually by qualified service personnel.
Clean the ceramic tile with compressed air. Avoid directing the air stream at the gasketing mate-
rial located between the tile and heater body. The air pressure must be lower than 20 psi.
Cause & remedy of back-firing:
A. Improper gas pressure entering the venturi
tube = check pressure.
B. Breakage of a ceramic tile and or gasketing
= replace damaged part.
C. Faulty sealing of the ceramic tile to the
burner body, caused by breakdown of gas-
keting material = contact your Schwank dis-
tributor.
