personal injury or loss of life. Read and understand the entire manual before attempting installation,
start-up operation, or service. Installation and service must be performed only by an experienced,
skilled, and knowledgeable installer or service agency.

adequate combustion and ventilation air.
• 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.
• Installation is not complete unless a safety relief valve is installed into the supply piping
immediately downstream of the boiler. - See the Water Piping and Trim Section of this manual for
details.
• This boiler is supplied with safety devices 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.
• Burn Hazard. 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.
• Respiratory Hazard. Boiler materials of construction, products of combustion and the fuel contain
alumina, silica, heavy metals, carbon monoxide, nitrogen oxides, aldehydes and/or other toxic or
harmful substances which can cause death or serious injury and which are known to the state of
California to cause cancer, birth defects and other reproductive harm. Always use proper safety
clothing, respirators and equipment when servicing or working nearby the appliance.
