GOLD CGs Gas-Fired Water Boiler — Boiler Manual
Please read before proceeding
Installer
Read all instructions before in-
stalling. 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.
The boiler contains ceramic fiber and fiberglass materials. Use care when handling these
materials per instructions on page 64 of this manual. Failure to comply could result in severe
personal injury.
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.
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 im
-
mediately 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.
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 techni
-
cian 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 medi
-
cines”. Serious damage to boiler, personnel and/or
property may result.
