CHIMNEY REQUIREMENTS
DANGER: A chimney which does not meet modern
safety standards will result in a fire or deadly carbon
monoxide poisoning of the building residents.
Chimney condition is of paramount importance for a safe and
efficient boiler installation. All new and replacement installa-
tions must include a chimney inspection by a qualified indi-
vidual or agency. Chimney construction materials must be
compatible with the fuel being used.
Particular attention should be paid on all oil-to-gas conver-
sions. Soot may have accumulated in chimney and/or
degraded chimney liner. Most utilities require complete chim-
ney cleaning. Others may require installation of new liner,
spill switches or other chimney upgrades. Check with local
utility for required safety precautions.
COMBUSTION AIR REQUIREMENTS
Provisions for combustion air must be in accordance with the
National Fuel Gas Code ANSI Z223.1 - latest edition, as well
as all applicable local codes. If the boiler is installed in an
unconfined space, adequate air will be available via normal
infiltration. However, if building construction is unusually tight
or the boiler is installed in a confined space (a space whose
volume is less than 50 cubic feet per 1000 Btu/hr of gas input
for all fuel burning equipment), adequate air for combustion
must be provided by two openings: one located about 6”
below the ceiling, the other about 6” above the floor. When
communicating directly with the outside or through a vertical
duct, each opening must have a minimum free area of one
square inch per 4000 Btu/hr of gas input. Horizontal ducts to
the outside must have a minimum free area of one square
inch per 2000 Btu/hr of gas input. When ventilation is provid-
ed by openings in doors, etc. to adjoining spaces having ade-
quate infiltration, each opening must have a minimum free
area of one square inch per 1000 Btu/hr of gas input.

NOTE: Boiler employs atmospheric combustion. Com-
bustion air must not be contaminated with halogenated
hydrocarbon vapors, aerosol propellants or freon. Other-
wise, boiler heat exchanger will be subject to corrosion,
reducing boiler life.
WATER TREATMENT
Water treatment is recommended in areas where water quali-
ty is a problem. A local water treatment company should be
consulted to determine the requirements for your particular
system and locality.
NOTE: Boiler is not for use in systems where water is
replenished. Minerals in the water can build up on the
heat transfer surfaces and cause overheating and subse-
quent failure of the heat exchanger.
NOTE: Boiler utilizes synthetic rubber seals. Water treat-
ment chemicals and system cleaning chemicals must be
compatible with this and all other construction materials.
SHIPMENT OF BOILER
Each boiler is shipped in a single carton.
Optional Vent Damper
When ordered, the vent damper is shipped in an individual
carton packaged with the boiler. Mounting of the damper and
flue outlet extension are required.
WARNING: Adequate fresh air must be provided for
combustion. Improper boiler operation and inade-
quate venting of deadly flue gases may otherwise
result.
