SERIES 5B ATMOSPHERIC:
GAS FIRED BOILER
SUGGESTED SPECIFICATIONS
Note: To use as a project specification:
A. Insert, in the blank spaces provided, the applicable model number, capacity, fuel, and electrical data.
B. Delete the item in parentheses or marked “*” which are not applicable to the project requirements.
C. Insert, where applicable, optional non-standard features desired.
1. GENERAL SPECIFICATION
Contractor shall furnish and install, where indicated on the drawings, ______ (quantity) Model 5_____ B,
_______ (steam or water) boiler(s) having an I=B=R approved gross output of ______ MBH and a net rating
of _______ MBH per boiler with an input of _______ MBH when fired with (natural or LP gas). Boiler(s)
shall be constructed of cast iron sections manufactured in accordance with ASME requirements for low
pressure boilers and each section shall be permanently marked with the ASME symbol and the maximum
allowable working pressure.
2. BOILER EQUIPMENT SPECIFICATION
2.1 Boiler sections shall have pinlike projections on each center section, evenly spaced on the vertical flue
surfaces to extract the greatest possible quantity of heat from the hot flue gases.
2.2 Boiler shall be equipped with stainless steel burners with air shutters which feature smooth ignition,
positive flame extinction and high combustion efficiency.
2.3 Boiler sections shall be surface ground to ensure smooth positive mating surfaces.
2.4 Boiler sections shall be assembled with precision machined cast iron push nipples, pressed into a
mating machined nipple port in the section eliminating the need for any material such as gaskets, etc.
which would be subject to deterioration due to corrosion or oil based chemicals.
2.5 Boiler shall have individual clean out openings between sections covered with insulated steel flue cover
plates on front and rear of boiler.
2.6 Boiler flue canopy(s) shall be constructed of heavy gauge aluminized steel.
2.7 A horizontal to vertical drafthood(s) shall be furnished for each boiler.
2.8 The boiler jacket shall be constructed of heavy gauge steel with 1” thick insulation and have a rust
resistant baked enamel finish. The jacket shall be capable of being installed after system piping has
been connected to the boiler section assembly. Jacket will have the capability of being removed for
cleaning the boiler without disturbing the system piping.
2.9 All boiler sections shall be hydrostatically tested for 50 psi water working pressure in accordance
with ASME Code, Section IV.
2.10 Boiler shall be manufactured of flake graphite/eutectic cell/ cast iron sections which shall have been
subjected to a hydrostatic pressure test of 2-1/2 times MAWP
at the factory before assembly and each
section shall be marked, stamped or cast with the ASME Code symbol. After section assembly, the
entire block of sections shall be hydrostatically tested at 1-1/2 times MAWP
prior to shipment. Boiler
shall be designed in accordance with the ASME Boiler and Pressure Vessel Code Section IV
requirements.
(NOTE TO SPECIFIER: The Series 5 boiler is shipped as standard with sections unassembled, however, if the
job conditions permit, we can factory assemble and water test up to 11 sections. Boiler sizes 12 thru 26 sections
will be shipped in two (2) or more assembled and tested blocks.)
* 2.10 Water trim shall include a 3½” round pressure-temperature gauge with separate scales for pressure and
water temperature. In addition, an ASME approved safety relief valve shall be furnished, sized to
exceed the gross output of the boiler, BTU/Hr. and shall be factory set to relieve pressure at
(30)(50)psi.
