WARNING
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.
This boiler must be properly vented. The 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 chimney must be inspected for any obstructions and cleaned
prior to each heating season. A clean and unobstructed chimney flue is necessary to produce the minimum
draft required to safely evacuate noxious fumes that could cause personal injury or loss of life. DO NOT
operate boiler with the absence of an approved vent system. Evidence of loose debris and or condensate
induced stains at the base of the chimney flue, connector or smokepipe joints may be signs of condensing
flue gases. Flue gas condensate is corrosive, which requires special consideration and must be addressed
immediately. Refer to "Venting (Natural Draft - Chimney)" listed in Table of Contents below .
This boiler needs fresh air for safe operation and must be installed so there are provisions for adequate
combustion and ventilation air.
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 flammable debris, rags,
paper, wood scraps, etc., should be kept clear of the boiler at all times. Keep the boiler area clean and
free of fire hazards.
