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. 

2.1      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.
