GOLD CGs-4E Gas-Fired Water Boiler — Boiler Manual
Please read before proceeding
Installer
Read all instructions before installing. Fol-
low 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 refer-
ence.
• We recommend regular service by a qualified service techni-
cian, at least annually .
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.
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 31.
Read and follow the special instructions for the Commonwealth of Massachusetts, located on page 36 of this
manual.
Failure to adhere to the guidelines on this page can result in severe personal injury, death or substantial
property damage.
When servicing boiler —
• To avoid electric shock, disconnect electrical supply before
performing maintenance.
• To avoid severe burns, allow boiler to cool before perform-
ing 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, caus-
ing leakage between sections. This can result in substantial
property damage.
• Do not use “homemade cures” or “boiler patent medicines”.
Severe personal injury, death or substantial property dam-
age may result.
• 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.
• 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 poten-
tial 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.
