INTRODUCTION
Empire Water boiler is a natural draft oil fired hot water
boiler comprised of cast iron sections. Empire Water
boiler is available with 3, 4, or 5 cast iron sections. These
sections are held together by cast iron push nipples.
Empire Water boiler is capable of firing #2 fuel oil from
0.80 gph up to 1.55 gph. All packaged boilers include a
swing door, Hydrolevel limit control with built-in low water
cutoff, temperature and pressure gauge, safety relief valve,
drain valve, flue brush, and extra boiler tap for expansion
tank or air elimination.
These low pressure oil fired hot water boilers are
constructed and hydrostatically tested for maximum
working pressure of 50 psig (pounds per square inch)
in accordance with the latest revision of the A.S.M.E.
(American Society of Mechanical Engineers) Boiler and
Pressure Vessel Code Section IV Standards for heating
boilers.
Heating Capacity indicates amount of heat available after
subtracting losses up the stack. Most of this remaining
heat is available to heat water. A small portion is heat from
the jacket and boiler surface and it is assumed that this
heat stays in the structure. Net AHRI Rating represents
portion of remaining heat that can be applied to heat
radiation or terminal units ( finned tube baseboard, cast
iron radiators, radiant floor, etc.). Difference between
Heating Capacity and Net AHRI Rating, called piping and
pickup allowance, establishes reserve for heating volume
of water in the system and off-setting heat losses from
system piping. Net AHRI Rating of the boiler selected
should be greater than or equal to calculated peak heating
load (heat loss) for building or area(s) served by the
boiler and associated hot water heating systems. Consult
manufacturer before selecting boiler for installations having
unusual piping and pickup requirements.
