External Inspection & Cleaning of the
Flame-trap

trap, use a vacuum, compressed air, or a soft bristle brush
to remove it. NOTE: If unable to inspect or clean the flame
trap from underneath, follow the “Cleaning the Combustion
Chamber and Flame-trap” instructions.
Cleaning the Combustion Chamber and
Flame-trap
1. Follow procedure outlined in “Removing the Manifold

compressed air to clear any dust or debris that may
have accumulated in the flame-trap.
3. Reassemble following the procedure under “Replacing
the Manifold Assembly”.
