Appliance 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.

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 appliance must be properly vented and connected to an approved vent system in good condition.

This boiler needs fresh air for safe operation and must be installed so there are provisions for adequate
combustion and ventilation air.

The interior of the venting and air intake systems must be inspected and cleaned before the start of the
heating season and should be inspected periodically throughout the heating season for any obstructions.
Clean and unobstructed venting and air intake systems are 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.

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,, natural and/or LP gas only. Do not use gasoline, crankcase
This boiler is designed to burn No. 2 fuel oil,, natural and/or LP gas 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). 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 V11H Series cast iron boilers are designed, built, marked and tested in accordance with the ASME Boiler
and Pressure Vessel Code, Section IV, Heating Boilers. An ASME Data Label is factory applied to each V11H
jacket, which indicates the boiler Maximum Allowable Working Pressure (MAWP). Each cast iron section is
permanently marked with the MAWP listed on the boiler’s ASME Data Label. Those values for the V11H are
as follows:
MAWP, Steam - 15 psi
MAWP, Steam - 15 psi
MAWP, Water (USA) - 80 psi
MAWP, Water (Canada) - 50 psi
It is common and acceptable practice to install these boilers in lower pressure systems, below the boiler
It is common and acceptable practice to install these boilers in lower pressure systems, below the boiler
MAWP. Therefore, Burnham Commercial offers safety relief valves set at or below the MAWP of the boiler.
See Table 1 for available safety relief valve set pressures.
