WARNING
This boiler contains very hot water under high pressure. DO NOT unscrew any pipe ttings 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 ow regulator and automatic mixing valve must be installed properly
in tankless heater piping. See Piping and Trim Sections 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.
A clean and unobstructed chimney ue 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 efciency.
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.
This boiler is designed to burn No. 2 fuel oil only. DO NOT use gasoline, crankcase drainings, or any
oil containing gasoline. Never burn garbage or paper in this boiler. DO NOT convert to any solid fuel
(i.e. wood, coal). DO NOT convert to any gaseous fuel (i.e. natural gas, LP). All ammable debris, rags,
paper, wood scraps, etc., should be kept clear of the boiler at all times. Keep the boiler area clean and
free of re hazards.
All boilers equipped with burner swing door have a potential hazard which if ignored can cause severe
property damage, personal injury or loss of life. Before opening swing door, turn off service switch to
boiler to prevent accidental ring of burner outside the combustion chamber. Be sure to tighten swing
door fastener completely when service is completed.
