MAINTENANCE

During Heating Season

1. Inspect the vent periodically for any blockages. Always
ensure that the vent cap fits loosely in order to prevent
the unit from becoming pressurized.
The Cozeburn is designed as an "Open to Atmosphere"
system and should never be under pressure!
2. The ash tray must be checked weekly and emptied as
necessary. Ensure that the ash tray is securely closed
after each cleaning. Adjust the latch if necessary.
Ashes should be placed in a metal container with a
tight fitting lid. The closed container of ashes should
be placed on a noncombustible floor or on the ground,
well away from all combustible material, pending final
disposal. Other waste should not be placed in the
container with the ashes.
3. Check the water level at least once a week to ensure the
level is well above the "ADD" mark.
Oxygen buildup causes corrosion inside the water
system. Keeping the water reservoir completely full
avoids oxygen buildup, especially during the summer
months when the furnace is not in use.
4. Check the door gasket to ensure an air tight fit and
maintain in good condition. Replace if necessary.
5. Turn off power.
6. Check and clean the damper cover to prevent creosote
buildup. Do this weekly until experience shows how
often cleaning is necessary.
A creosote buildup could cause the damper to seize,
causing the circuit breaker to disengage.
7. Inspect the chimney and chimney connector monthly
during the heating season to determine if a creosote
buildup has occurred. Maintain and clean if there is
a buildup of creosote. When wood is burned slowly, it
produces tar and other organic vapors, which combine
with expelled moisture to form creosote. The creosote
vapors condense in the relatively cool chimney flue
of a slow burning fire. As a result, creosote residue
accumulates on the flue lining. When ignited, this
creosote makes an extremely hot fire. When burning
wood, the chimney connector and chimney should be
inspected monthly
if creosote has accumulated, it must be removed to
reduce the risk of a chimney fire.
A buildup of creosote will also cause a poor draft.
8. Cover plates and guards must be in place at all times,
except during maintenance and servicing.
9. Canadian requirements for supplementary (add-on)
boilers:
- operate the original gas, oil or electric boiler
periodically to ensure that it will operate satisfactorily
when needed;
20
during the heating season, and
- do not relocate or bypass any of the safety controls in
the original gas, oil or electric boiler installation;
- the operation of a gas boiler must be verified for
acceptable operation, before and after installation of
the add-on appliance, by a gas fitter who is recognized
by the local and national regulatory authority;
- do not connect to any chimney or vent serving a gas
appliance.

End of Heating Season

Cleaning of the heat exchanger, flue pipe, chimney and draft
inducer if used, is especially important at the end of the
heating season to minimize corrosion during the summer
months caused by accumulated ash.
1. Thoroughly clean the furnace of any creosote or ash
buildup.
Hardened creosote or ashes are easier to be removed
when furnace is still warm.
2. Check to ensure there is no moisture in any part of the
inside of the firebox, or in the ash tray.
Failing to properly clean the furnace and protect it
from moisture during the off-season will void the
warranty.
3. Cover and seal the chimney to prevent any rain or
moisture from entering the firebox chamber while not in
use.
4. Ensure the water reservoir is full during the non-heating
season to prevent corrosion inside the water jacket.
5. Add a sufficient amount 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.
6. 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 file. 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 be between 8.8 and 11.0, a nitrate
level between 730 and 1460 ppms as NaNO2, and a
conductivity must be less than or equal to 4000 mmhos.
If the pH or nitrite level is low, more Pro-Fab approved
water treatment should be added. If the level of
conductivity is too high, 1/2 the water in the unit should
be drained and replaced with fresh water.
Failing to use Pro-Fab approved water treatment
in accordance with the Installation and Operation
Instructions will void the warranty. See your dealer
for authorized supplies. It is the responsibility of the
owner to maintain yearly water sample results on file.
