To begin End of Season Shutdown of your Heatmor™ Outdoor Furnace, follow the instructions below:
1. Turn off pump(s).
2. Clean Flue (Refer to the “Flue” section of the Heatmor
TM
Operations and Maintenance Manual.)
a) Remove Flue Cover(s)
b) Using the flue scraper provided with the HEATMOR™ furnace, push the dust to the front of the
flue and let it fall down into the firebox. Remove this dust as you would ashes. If a lot of dust is
dropped down, be certain that the air slot of the front air box is not covered. If there is a two pass flue,
clean the top flue through the flue access ports.
c) Re-attach the flue cover plate(s), making sure to tighten the nuts to make an airtight seal.
3. Clean ashes out of Firebox. (Refer to the “Ashes” section of the Heatmor
TM
Operations and Maintenance
Manual.)
a) Thoroughly pull ashes from sides and corners of Firebox. Rake ashes in Firebox down into the
grates.
4. Auger ashes out of Ash Pan. (Refer to the “Ashes” section of the Heatmor
TM
Operations and
Maintenance Manual.)
5. Place cap on Chimney. There is no specific product sold for this use, but a five gallon bucket or
something similar will cover the chimney keeping unwanted moisture and visitors away.
6. Properly clean and oil Fan(s). (Refer to the “Air Supply” section of the Heatmor
TM
Operations and Mainte-
nance Manual.)
1) Turn off the main power supply to the furnace.
2) Loosen and remove the two thumb nuts securing the
blower / flipper assembly to the large air tube, and remove the
blower / flipper 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 appropriate 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 fins of the blower.
5) With a scraper or brush, remove any residue built up on the flipper assembly.
6) Ensure the flipper is resting completely on its seat. If it is not
resting completely, perhaps there is dust or soot built up on the flipper,
or some other obstruction not allowing it to close tightly.
7) Replace firebox door elbows every other season. If you did not change your firedoor elbows last
year, it is strongly suggested to change them following the steps on page 40.
8) Securely fasten the blower / flipper assembly back to the large air tube
ensuring there are no air leaks.
7. Check PH level of your system water. Your PH level should be between 8 - 10. (Refer to the “Water” section
in the Heatmor™ Operations and Maintenance Manual.)
