NOTICE
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).
NOTICE
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.
USA boilers built for installation at altitudes greater than 2,000 feet above sea level have been specially
oriced 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, Section 8.1.2 and Appendix F. Canadian boilers’ orice sizing is indicated on the
rating label.
