Prepare boiler location — codes
&
checklist
1a
Before placing boiler in boiler room, mount the
ambient tempera-
ture 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 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.

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.

• 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.
