WARNING
This boiler requires regular maintenance and service to operate safely. Follow the instructions contained
in this manual.
Improper installation, adjustment, alteration, service or maintenance can cause property damage, personal
injury or loss of life. Read and understand the entire manual before attempting installation, start-up,
operation, or service. Installation and service must be performed only by an experienced, skilled, and
knowledgeable installer or service agency.
This boiler must be properly vented.
This boiler needs fresh air for safe operation and must be installed so there are provisions for adequate
combustion and ventilation air.
The interior of the venting system must be inspected and cleaned before the start of the heating season
and should be inspected periodically throughout the heating season for any obstructions. A clean and
unobstructed venting system is necessary to allow noxious fumes that could cause injury or loss of life
to vent safely and will contribute toward maintaining the boiler’s efficiency.
This boiler is supplied with safety devices which may cause the boiler to shut down and not re-start
without service. If damage due to frozen pipes is a possibility, the heating system should not be left
unattended in cold weather; or appropriate safeguards and alarms should be installed on the heating
system to prevent damage if the boiler is inoperative.
This boiler contains very hot water or steam under pressure. Do not unscrew any pipe fittings nor attempt
to disconnect any components of this boiler without positively assuring the water is cool and has no
pressure. Always wear protective clothing and equipment when installing, starting up or servicing this
boiler to prevent scald injuries. Do not rely on the pressure and temperature gauges to determine the
pressure and temperature of the boiler. This boiler contains components which become very hot when
the boiler is operating. Do not touch any components unless they are cool.
