Steps to Maintain your Blower / Flipper Assembly.
1. Turn off the main power supply to the furnace.
2. Loosen and remove the two thumb nuts securing
the blower / ipper assembly to the large air tube,
and remove the blower / ipper assembly.
3. Lubricate the blower motor every six months with 10
to 20 drops of SAE 10W or 20W non-detergent oil
(ML Type) or with electric motor oil in the appropri-
ate oil holes. The oil holes are on the bottom of the
blower.
4. With a small brush, scrape any dust or residue that has accumulated on the ns of the
blower.
5. With a scraper or brush, remove any residue built up on the ipper assembly.
6. Ensure the ipper is resting completely on its seat. If it is not resting completely, per-
haps there is dust or soot built up on the ipper, or some other obstruction not allowing
it to close tightly.
7. Securely fasten the blower / ipper assembly back to the large airtube
Combustion Air Blower
Removal and Replacement
1. Turn off the main power supply to the furnace.
2. Loosen and remove the thumb-nuts securing the blower / ipper assembly to the air
tube.
3. Disconnect the electrical wire from the blower.
4. Remove the ipper assembly from the blower by removing the four bolts. This will
require a 7/16 inch wrench.
5. Attach the existing ipper assembly to the new blower.
6. Rewire the electrical wire to the blower. Contact a licensed electrician if you have any
questions.
7. Securely fasten the blower back to the air tube ensuring that there are no air leaks.
THE FLIPPER MUST OPERATE PERFECTLY OR PROBLEMS QUICKLY ARISE.
If the ipper is unable to open and close freely, or remains partially open or partially closed,
the furnace will starve for air resulting in a smoldering re instead of an intense re. More
smoke and creosote is the result. If the ipper is not operating correctly, it causes a snow-
ball effect of problems. MAINTAIN THE FLIPPER!
