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.
Installation is not complete unless a safety (relief) valve is installed. See the Piping and Trim
Section of this manual for details.
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

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.
