Owner's Manual

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.

These boilers contain 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.

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

Do not operate boilers with the absence of an approved vent system.

These boilers need 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.

These boilers are 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 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.

Float type low water cutoff devices require annual inspection and maintenance. Refer to instructions in

Section V, Paragraph 7 of the Series 8H/8HE Installation, Operating and Service Instructions for inspection

and cleaning instructions.

All Series 8HE 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 8HE

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. The MAWP for all Series 8HE

Boiler is 50 psi (Water Only).

It is common and acceptable practice to install these boilers in lower pressure systems, below the boiler

MAWP. Therefore, in addition to Safety Relief Valves set for 50 psi, Burnham also offers Safety Relief Valves

set for 30 psi (By Special Order Only).
