NOTICE:
1. This boiler has a limited warranty, a copy of which is printed on the back of this manual. It is the responsibility
of the installing contractor to see that all controls are correctly installed and are operating properly when
the installation is complete. The warranty for this boiler is valid only if the boiler has been installed, maintained and
operated in accordance with these instructions.
2. Boilers built for installation at altitudes 2,000-5,000 ft. above sea level have been specially orificed to reduce
gas input rate 4 percent per 1,000 feet above sea level per the National Fuel Gas Code, NFPA 54/ANSI Z223.1.
3. 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 Commercial also offers Safety Relief Valves set
for 30 psi (By Special Order Only).
