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

1a Prepare boiler location — codes & checklist

Installations must follow these codes:

Local, state, provincial, and national codes, laws, regulations and ordinances.

National Fuel Gas Code, ANSI Z223.1–latest edition.

Standard for Controls and Safety Devices for Automatically Fired Boilers, ANSI/ ASME CSD-1, when required.

National Electrical Code.

For Canada only: B149.1 or B149.2 Installation Code, CSA C22.1 Canadian Electrical Code Part 1 and any local codes.

The CGi-4E boiler gas manifold and controls met safe lighting and other performance criteria when boiler underwent tests specified in ANSI Z21.13–latest edition.

Read and follow the special instructions for the Commonwealth of Massachusetts, located on page 42 of this manual.

Before locating the boiler, check the following:

Check for nearby connection to:

System water piping

Venting connections

Gas supply piping

Electrical power

Check area around boiler. Remove any combustible materials, gasoline and other flammable liquids, or other contaminants.

Failure to keep boiler area clear and free of combustible mate- rials, gasoline and other flammable liquids and vapors can

result in severe personal injury, death or substantial property damage.

Boiler must be installed so that gas control system components are protected from dripping or spraying water or rain during operation or service.

If new boiler will replace existing boiler, check for and correct system problems, such as:

1.System leaks causing oxygen corrosion or section cracks from hard water deposits.

2.Incorrectly-sized expansion tank.

3.Lack of antifreeze in boiler water causing system and boiler to freeze and leak.
