GOLD CGs-4E Gas-Fired Water Boiler — Boiler Manual

1d Prepare boiler location — contamination

Please review the following information on potential combustion air contamination problems.

Refer to Table 1 for products and areas which may cause contaminated combustion air.

All CGs-4E boilers must be direct vented (using ducted outside air). The vent/air termination must be installed in a location that is free of the contaminants listed below. Allowing the boiler to operated with contaminated air can cause damage to the boiler and vent system, resulting in possible severe personal injury, death or substantial property damage.

Products to avoid

Spray cans containing chloro/fluorocarbons

Permanent wave solutions

Chlorinated waxes/cleaners

Areas likely to have contaminants

Dry cleaning/laundry areas and establishments

Swimming pools

Metal fabrication plants

Beauty shops

Refrigeration repair shops

Photo processing plants

Auto body shops

Plastic manufacturing plants

Furniture refinishing areas and establishments

New building construction

Remodeling areas

Garages with workshops

Buildings under construction (where air is contaminated with particulates)

CONSTRUCTION DUST HAZARD — Airborne particulates, such as drywall dust or fiberglass dust, will cause blockage of the CGs-4E burners, resulting in carbon monoxide production, a fire hazard, or building freeze damage. If the boiler is operated during construction, you must isolate the boiler air supply to provide clean air for combus- tion. Follow the instruction manual guidelines for piping intake air. If you are unable to ensure uncontaminated air in the boiler air intake at all times, you must inspect the boiler at least once weekly. When inspecting, clean the burners if necessary using the procedure given on page 39. Failure to follow these guidelines could result in severe personal injury, death or substantial property damage.
