20 EMPYRE PRO SERIES INSTALLATION AND OPERATION MANUAL
MAINTENANCE
During Heating Season
1. Establish a daily routine for storage of fuel and care of
the furnace. Check frequently for crusted ash buildup
until experience shows how often cleaning is necessary.
Be awarethat the hotterthe re, the less ash/tar is
depositedintherebox,andthatweeklycleaningsmay
be necessary in mild weather, even though monthly
cleanings may be enough in the coldest months. Have
a clearly understood plan in place in the event of a
chimneyre.
2. The secondary burn chamber must be cleaned out
weekly or as necessary. Ensure that the ash clean out
door is securely closed after each cleaning.
Place all removed ash in a steel container with a tightly
tting lid. Other waste should not be placed in the
container with the ashes.
3. Check the water level at least once a week, ensure the
level is well above the “ADD” mark.
Oxygen buildup causes corrosion inside the water
system. Keeping the water reservoir completely full
prevents oxygen buildup, especially during the summer
months when the furnace is not in use.
4. Checkthedoorandlidgasketstoensureanairtightt.
Adjust hinges and latch as needed.
5. Check and clean the heat exchanger ues weekly. A
buildupinthechimneyandueswillcauseapoordraft
andreduceefciency(seepg18).
6. Cover plates and guards must be in place at all times,
except during maintenance and servicing.
7. Rear access door must be secure with latch locking
bolt. Tighten with a wrench.
8. Inspect brickaspartofroutineloadingof therebox
(see pg 17).
9. All doors must be closed during operation.
End of Heating Season
1. Thoroughly clean the rebox door frame, secondary
burn chamber, ue area, and ues of any loose or
crusted ash buildup. Crusted ashes are easier to
remove when furnace is still warm. Note: A thin black
coating in the rebox is acceptable, but ensure that
there is no ash in contact with bare metal.
2. Check secondary air passage and clean if necessary.
To check, remove several of the bricks on the left side
oftherebox.Theairpassageisnowvisible.Notethe
small air holes at each of the brick slots. Ensure that air
isfreetoowtoeachairhole.Alsoinspectthevertical
air tube, if there is creosote buildup, clean opening
at top of air tube with brush. Also remove blower and
apper. Through square openings, insert brush into
air passages (2 on Pro Series 200; 3 passages on Pro
Series 400). Reinstall the bricks in reverse order.
3. Check for damaged brick and replace as necessary.
Contact your dealer for replacement brick.
4. Check to ensure there is no moisture in any part of the
insideoftherebox,secondaryburnchamber,orue
area. Apply a thin lm of oil in the ue area and on
thedoorframeandreboxwherethereisbaremetal
surfaces that do not have a black tar coating.
5. Cover and seal the chimney to prevent any rain or
moisture from entering the heat exchanger area while
not in use.
Failing to properly clean the furnace and protect it
from moisture during the off-season will void the
warranty.
6. Ensure the water reservoir is full during the non-heating
season to prevent corrosion inside the water jacket.
7. Add the correct amount (as indicated on water
treatment bottle) of Pro-Fab approved water treatment
to the water system each year after the heating season.
Operate the water circulating pump for 24 hours after
adding water treatment to ensure proper mixing of the
water treatment with the water.
8. A water sample must be drawn 30 days after purchase
of the unit and forwarded to your dealer for testing.
Maintain the results of this test on le. Thereafter,
draw a water sample once a year and forward to your
dealer for testing.
Water properly treated with Pro-Fab approved water
treatment should have a ph level between 8.8 and
11.0, a nitrate level between 700 and 1460 ppms as
NaNO2, and a conductivity must be less than or equal
to 4000 mmhos.
If the pH is not within tolerance, treat by adding a ratio
of 1 part of Pro-Fab approved Wood Burning Furnace
Treatment (WBFT) to 300 parts of system water and re-
test. If the nitrate is less than 700 ppm, treat by adding
a ratio of 1 part WBFT to 300 parts of system water
and re-test. If the conductivity is higher than 4000
micromhos,drain50%ofthesystemwater.Relland
treat by adding a ratio of 1 part WBFT to 300 parts of
system water and re-test.
Failing to use Pro-Fab approved water treatment
in accordance with the Installation and Operation
Instruction Manual will void the warranty. See your
dealer for authorized supplies. It is the responsibility
of the owner to maintain yearly water sample results
on le.
