LOGS

MAIN BURNER
Periodically inspect all burner flame holes with
the heater running. All slotted burner flame
holes should be open with flame present. All
round burner flame holes should be open with
a small blue flame present. Some burner flame
holes may become blocked by debris or rust,
with no flame present. If so, turn off heater and
let cool. Remove blockage, blocked burner
flame holes will create soot.
WARNING: The injector
holders (air shutters) are not
adjustable. Do not move the in
-
jector holders from their original
positions.
