GOLD CGi-4E 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.

•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.

The boiler contains ceramic fiber and fiberglass materials. Use care when handling these materials per instructions on page 68 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 37.

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 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.

•Continual fresh makeup water will reduce boiler life. Mineral buildup in sections re- duces 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.
