Boiler Manual
Please read before proceeding
Installer
Read all instructions before
installing.
Follow all instructions in
proper order to prevent personal
injury or death.
• Also refer to CGs Venting Supplements.
• Consider piping and installation when
determining boiler location.
• Any claims for damage or shortage in shipment
must be filed immediately against the
transportation company by the consignee.
User
• This manual is for use only by your qualified
heating installer/service technician.
• Please refer to the User’s Information Manual for
your reference.
• We recommend regular service by a qualified
service technician, at least annually
.
When calling or writing about the boiler— Please have the boiler model number from the
boiler rating 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 found on page 30.
Failure to adhere to the guidelines on this page can result in severe personal injury, death
or substantial property damage.
• 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.
• Do not add cold water to hot boiler. Thermal
shock can cause sections to crack.
When servicing boiler —
• To avoid electric shock, disconnect electrical
supply before performing maintenance.
• To avoid severe burns, allow boiler to cool before
performing maintenance.
Boiler operation —
• Do not block flow of combustion or ventilation
air to boiler.
• Should overheating occur or gas supply fail to
shut off, do not turn off or disconnect electrical
supply to circulator. Instead, shut off the gas
supply at a location external to the appliance.
• 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 —
• Do not use petroleum-based cleaning or sealing
compounds in boiler system. Water seal
deterioration will occur, causing leakage between
sections. This can result in substantial property
damage.
• Do not use "homemade cures" or "boiler patent
medicines". Serious damage to boiler, personnel
and/or property may result.
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.
