Manual
If the information in this manual is not followed exactly, a fire or
explosion may result, causing property damage, personal injury or
loss of life.
Do not store or use gasoline or other flammable vapors and liquids in the
vicinity of this or any other appliance.
WHAT TO DO IF YOU SMELL GAS
• Do not try to light any appliance.
• Do not touch any electrical switch; do not use any phone in your
building.
•
Immediately call your gas supplier from a neighbor’s phone. Follow
the gas supplier’s instructions.
• If you cannot reach your gas supplier, call the fire department.
Installation and service must be performed by a qualified installer, service
technician or the gas supplier.

To prevent potential of severe personal injury or death, check for products or
areas listed in table at right before installing boiler. If any of these contaminants
are found:

•
•
To avoid severe burns, allow boiler to cool before performing maintenance.
Hydrochloric acid/muriatic acid
Cements and glues
You must maintain the boiler as outlined in the manual and have the boiler
started up and serviced at least annually by a qualified service technician
to ensure boiler/system reliability.
Antistatic fabric softeners used in clothes

Boiler operation
Chlorine-type bleaches, detergents, and
cleaning solvents found in household

•
Do not block flow of combustion or ventilation air to boiler. This boiler is
equipped with a control which will automatically shut down the boiler should
air or vent be blocked. If vent or air blockage is easily accessible and removable,
remove it. The boiler should attempt to restart within an hour. If blockage is
not obvious or cannot be removed, have the boiler and system checked by a
qualified service technician.

Areas likely to have
contaminants
•
•
•
Should overheating occur or gas supply fail to shut off, do not turn off or
disconnect electrical supply to pump. Instead, shut off the gas supply at a
location external to the appliance.
Dry cleaning/laundry areas and establish-
ments
Do not use this boiler if any part has been under water. Immediately call a
qualified service technician to inspect the boiler and to replace any part of the
control system and any gas control, which has been under water.
Swimming pools
Metal fabrication plants
Beauty shops
Have the building monitored when it is vacant for an extended period. Safety
controls can shut down the boiler at any time. The loss of heat can result in
significant damage due to freezing.
Refrigeration repair shops
Photo processing plants
Auto body shops
Boiler water
•
DO NOT use petroleum-based cleaning or sealing compounds in boiler system.
Water seal deterioration will occur, causing leakage between sections and damage
to heating system components. This can result in substantial property damage.
Plastic manufacturing plants
•
•
DO NOT use "homemade cures" or "boiler patent medicines". Serious damage
to boiler, personnel and/or property may result.
Furniture refinishing areas and establish-
ments
Continual fresh makeup water will reduce boiler life. Mineral buildup in
sections reduces heat transfer, overheats cast iron, and causes section failure.
Addition of oxygen and other gases can cause internal corrosion. Leaks in boiler
or piping must be repaired at once to prevent makeup water.
New building construction
Remodeling areas
•
Do not add cold water to hot boiler. Thermal shock can cause sections to
crack.

User maintenance procedures
Boiler must be serviced & maintained
The following information
provides detailed instructions for
completing the maintenance items
listed in the maintenance schedule,
page 6. In addition to this
maintenance, the boiler must be
serviced and started up at the
beginning of each heating season
by a qualified service technician.
The boiler should be inspected and started annually, at
the beginning of the heating season, only by a qualified
service technician. In addition, the maintenance and
care of the boiler designated on page 6 and explained
on the following pages must be performed to assure
maximum boiler efficiency and reliability. Failure to
service and maintain the boiler and system could result
in equipment failure, causing possible severe personal
injury, death or substantial property damage.

Propane gas odorant
Propane boilers only — Your propane supplier mixes an odorant with the propane to make its presence detect-
able. In some instances, the odorant can fade and the gas may no longer have an odor.
•
Propane gas can accumulate at floor level. Smell near the floor for the gas odorant or any unusual odor. If you
suspect a leak, do not attempt to light the pilot.
•
Use caution when attempting to light the propane pilot. This should be done by a qualified service techni-
cian, particularly if pilot outages are common.
•
•
•
Periodically check the odorant level of your gas.
Inspect boiler and system at least yearly to make sure all gas piping is leak-tight.
Consult your propane supplier regarding installation of a gas leak detector. There are some products on the
market intended for this purpose. Your supplier may be able to suggest an appropriate device.
