WARNING
This boiler contains very hot water under 12 - 15 PSI 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.
High water temperatures increase the risk of scalding injury. If this boiler is equipped with a tankless
heater for domestic water supply, a flow regulator and automatic mixing valve must be installed properly
in tankless heater piping. See Water Piping and Trim Section of this manual for details.
This boiler must be properly vented and connected to an approved vent system in good condition. Do
not operate boiler with the absence of an approved vent system.
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 needs fresh air for safe operation and must be installed so there are provisions for adequate
combustion and ventilation air.
This boiler must be connected to an approved chimney or vent system in good condition. Serious property
damage could result if the boiler is connected to a dirty or inadequate chimney or vent system. The
interior of the chimney flue must be inspected and cleaned before the start of the heating season for any
obstructions. A clean and unobstructed chimney flue 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.
DO NOT operate boiler with the absence of an approved vent system.
This boiler is supplied with controls 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.
