2. Clean the ash from the combustion chamber (see Figure 9D):
a. If the air and oil lines must be disconnected to open the clean out door:
1. Bleed-down pressure on the air and oil lines by slightly loosening the fittings at the bottom of
the connector block.
2. With air and oil pressure completely bled off, disconnect the air and oil pressure lines from
the bottom of the connector block.
NOTE: Cover these lines to keep dirt from entering the air / oil supply.
b. Remove the lock nuts on the clean-out door.
c. Carefully swing open the clean-out door to expose the coiled heat exchanger, flue passages,
and the combustion chamber.
d. Remove the ceramic sleeve from the combustion chamber, and remove the supporting stand.
e. Use a wire or bristle brush to thoroughly clean out the ash from the combustion chamber and
flue passages.
f. While cleaning out the combustion chamber, also check the burner retention head and throat.
Carefully clean these elements.
g. Thoroughly vacuum any remaining ash residue from the flue passages. A long wand on the
hose of your shop vac is helpful in reaching all the way back.
h. Inspect the combustion chamber and its components to ensure that it is in good condition.
Inspect the inside of the clean-out door and target wall. Make sure the refractory material on
the inside of the door is in good condition, and the door seals tightly when closed. If the
door does not seal tightly, replace any damaged components.
3. Clean the ash from the stack components:
a. Brush accumulated ash from the stack cap.
b. Lightly tap the stack components to loosen the ash.
c. Allow ash and dust to settle in the clean-out tee or elbow, then vacuum out.
d. Disconnect the stack from the CTB breach.
e. Thoroughly vacuum out the back of the boiler, including the boiler breach (through the
breach). If desired, the back panel can be removed for cleaning.

DO NOT bump or bend burner
components while cleaning the
combustion chamber.
