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.
Before locating the boiler,
check the following:
• Check for nearby connection to:
• System water piping
• Venting connections
• Gas supply piping
• Electrical power

Install ambient temperature switch
Before placing boiler in boiler room, mount the
ambient temperature switch on the wall that will be
closest to the boiler as shown at right. Mount the switch
no more than 5 inches from the ceiling, as shown.
Connect the switch wires to the switch after placing
the boiler in position.

The CGt boiler gas manifold and
controls met safe lighting and other
performance criteria when boiler
underwent tests specified in ANSI
Z21.13–latest edition.
The ambient temperature switch
prevents overheating of the boiler
components and combustible
materials in the vicinity of the
boiler in the event ventilation air
should be blocked. Failure to install
the switch as shown could result in
severe personal injury, death or
substantial property damage.
• Check area around boiler. Remove any combustible
materials, gasoline and other flammable liquids.
Failure to keep boiler area clear and
free of combustible materials,
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.
