Cleaning the Ash (continued)
1. Ensure that power has been turned OFF, and all "hot" components have been allowed to cool sufficiently.
Carefully remove the Energy Retention Disc with a long handle or pipe. Lightly vacuum off the Energy
Retention Disc.
2. 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 elbow on the stack.
NOTE: It is not necessary to remove the stack to clean it. You will vacuum ash from the
stack elbow as you clean out the back of the furnace as described below.
d. Remove the clean-out cap from the unused furnace breach.
e. Thoroughly vacuum out the back of the furnace, including the stack elbow, through the
clean-out breach. A long wand on the hose of your shop vac is helpful in reaching all the
way through the back of the furnace to the stack elbow.
3. Clean the ash from the combustion chamber (see Figure 9E):
a. Bleed down pressure on the air and oil lines by slightly loosening the fittings at the bottom of
the connector block.
NOTE: Turn off the shut-off on the air pressure line.
b. With air and oil pressure completely bled off, disconnect the air and oil pressure lines from
the bottom of the connector block.
NOTE: Cover the lines to keep dirt from entering the air / oil supply
c. Remove the lock-down nuts on the clean-out door.
d. Carefully swing open the clean-out door to expose the heat exchanger flues and the
combustion chamber.
e. Check the color of the ash--it should be light gray or tan.
ATTENTION: White ash indicates excessive air pressure. Black ash or soot indicates lack of
combustion air. If these conditions exist, call your Clean Burn dealer. DO NOT overfire
your furnace by turning up the compressed air. Overfiring will damage the combustion
chamber and heat exchanger and will void your warranty.
f. Vacuum the ash from the combustion chamber and the flues.
ATTENTION: When cleaning the combustion chamber, ensure that you do not gouge or
damage the refractory material on the inside of the clean-out door.
NOTE: Avoid "packing" the ash in the tubes by first vacuuming the flues before pushing
the flue brush down the flues. DO NOT bump or bend burner components while cleaning the
combustion chamber.
g. Use a flue brush to thoroughly clean the flues.
h. Thoroughly vacuum any remaining ash residue from the flues. Make sure the back (at the
breach) is still clean.
i. Check the flues for rust.
ATTENTION: The presence of rust in the flues indicates that chlorinated materials are
being burned. Burning chlorinated materials will severely damage your heat exchanger and
void your warranty. Contact your Clean Burn dealer for instructions to test your oil for
chlorine contamination before firing your furnace.
j. Inspect the inside of the clean-out door. Make sure the refractory material on the inside of
the clean-out door is in good condition and the clean-out door seals tightly when closed. If
the door does not seal tightly, replace any damaged components.
