LOGS
• If you remove logs for cleaning, refer to
Installing Logs, page 17, to properly replace
logs.
• Replace log(s) if broken or chipped (dime-
sized or larger).
Periodically inspect all burner ame holes with
the heater running. All slotted burner ame
holes should be open with yellow ame pres-
ent. All round burner ame holes should be
open with a small blue ame present. Some
burner ame holes may become blocked by
debris or rust, with no ame present. If so,
turn off heater and let cool. Remove blockage.
Blocked burner ame holes will create soot.
