damage.
Improper installation, adjustment, alteration, ser-
vice or maintenance can cause property damage,
personal injury, exposure to hazardous materials, or
loss of life. Refer to the User's Information Manual
provided with this boiler. Installation and service
must be performed by a qualified installer, service
agency or the gas supplier who must read and follow
the supplied instructions before installing, servicing
or removing this boiler. This boiler contains possibly
carcinogenic, to humans.
When calling or writing about the boiler: Please
have the boiler model number from the boiler rat-
ing label and the CP number from the boiler jacket.
You may list the CP number in the space provided
on the Installation and Service Certificate
page 27.

Failure to adhere to the guidelines below can
result in severe personal injury, death or sub-
stantial property damage.
When servicing boiler —
1. The boiler contains ceramic fiber and fiberglass materials.
Use care when handling these materials per instructions
on page 28 of this manual. Failure to comply could result
in severe personal injury.
2. To avoid electric shock, disconnect electrical supply before
performing maintenance.
3. To avoid severe burns, allow boiler to cool before perform-
ing maintenance.
Boiler operation —
4. Do not block flow of combustion or ventilation air to
boiler.
5. Should overheating occur, turn off or disconnect electrical
supply to boiler and shut off the gas supply at a location
external to the appliance, if possible.
6. 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 that has been under water.
Boiler water —
7. DO NOT use petroleum-based cleaning or sealing com-
pounds in boiler system. Water seal deterioration will
occur, causing leakage between boiler sections, circulator
flanges, diaphragm tanks or other system components.
This can result in substantial property damage.
8. DO NOT use " homemade cures " or " boiler patent
medicines". Serious damage to boiler, personnel and/or
property may result.
9. Continual fresh makeup water will reduce boiler life. Min-
eral 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.
10. Do not add cold water to hot boiler. Thermal shock can
cause sections to crack.
Glycol — potential fire hazard —
All glycol is flammable when exposed to high temperatures. If
glycol is allowed to accumulate in or around the boiler or any
other potential ignition source, a fire can develop. In order to
prevent potential severe personal injury, death or substantial
property damage from fire and/or structural damage:
• Never store glycol of any kind near the boiler or any
potential ignition source.
• Monitor and inspect the system and boiler regularly for
leakage. Repair any leaks immediately to prevent possible
accumulation of glycol.
• Never use automotive antifreeze or ethylene glycol in the
system. Using these glycols can lead to hazardous leakage
of glycol in the boiler system.
