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
"Natural Draft Venting (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.
• 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 firing of burner outside the combustion chamber. Be sure to tighten swing door fasteners
completely when service is completed.
