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 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 and air intake systems must be inspected and cleaned before the start of the
heating season and should be inspected periodically throughout the heating season for any obstructions.
Clean and unobstructed venting and air intake systems are 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 under high 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
temperature and pressure 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.
Boiler materials of construction, products of combustion and the fuel contain alumina, silica, heavy metals,
carbon monoxide, nitrogen oxides, aldehydes and/or other toxic or harmful substances which can cause
death or serious injury and which are known to the state of California to cause cancer, birth defects and
other reproductive harm. Always use proper safety clothing, respirators and equipment when servicing
or working nearby the appliance.
Failure to follow all instructions in the proper order can cause personal injury or death. Read all instructions,
including all those contained in component manufacturers manuals which are provided with the boiler
before installing, starting up, operating, maintaining or servicing.
Keep boiler area clear and free from combustible materials, gasoline and other flammable vapors or
liquids.
All cover plates, enclosures and guards must be in place at all times.
This product must be installed by a licensed plumber or gas fitter when installed within the Commonwealth
of Massachusetts.

of the installing contractor to see that all controls are correctly installed and are operating properly when the
installation is complete.
