Flue Plugged

BURNER WON'T STAY ON OR MAKING POOFING SOUNDS

If the burner shuts off after a minute or so, or is making poofing sounds, try opening the fire box door and starting the burner again. If the burner stays on and does not make poofing sounds, the flue pipe or the flue cap may be plugged. If the flue becomes clogged, the burner is not able to continue blowing in the fire. The pressure inside the pit will keep the burner from working.

This is a dangerous situation and must be corrected immediately. If there are any bends or offsets in the flue pipe, these areas will become clogged as the creosote will condense and collect in these areas.
