WARNING
This boiler must be properly vented. 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. 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 Section IV, "Venting" or Section V "Direct Venting / Air Intake
Piping".
• 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.
• Asphyxiation Hazard. The interior of the venting system must be inspected and cleaned before the start of the
heating season and should be inspected periodically throughout the heating season for any obstructions. A
clean and unobstructed venting system 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.
• 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, unplug burner power cord
from receptacle located in lower right corner of jacket front panel and 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.
