PROBLEM
CAUSE: To rich air/fuel mixture
Orange, lazy flame

or replace door gaskets.
Check that all outside connections are clear of any obstructions.
Check the exhaust system; clean as needed.
PROBLEM
CAUSE: Burnpot burns out of fuel
Fire goes out or stove

Hopper is empty, refill the hopper.
Loss of draft pressure. Make sure that the viewing door is closed and sealed properly. If not,
adjust door catch and/or replace door gaskets. Check that all outside connections are clear
