1.  GENERAL SPECIFICATION 

Contractor shall furnish and install, where indicated on the drawings,  ______ (quantity) Model  
V-9______A,  ______ (steam or water), ______ (#2 Oil, Nat. or LP Gas, #2 Oil and Nat. or LP Gas) 
pressure fired boiler-burner unit(s), having an I=B=R approved gross output of  ______ MBH per boiler 
and a net rating of ______ MBH with an I=B=R burner capacity of _______ MBH (Gas) ______ GPH 
(#2 Oil).  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 pressures.  The boiler-burner unit shall not require a 
refractory combustion chamber and the sections shall be of wet base construction.  Further, the boiler-
burner unit shall be designed so that only a vent shall be required that extends only 3 feet above the 
highest point of the roof. 

 

2.  BOILER EQUIPMENT SPECIFICATION 
    *2.1  The boiler shall be furnished as a knocked down unit for field erection according to the              

manufacturer’s instructions. 

      *(NOTE TO SPECIFIER:  The V9 boiler-burner unit is shipped as standard with sections         

unassembled.  However, if job conditions permit, the following options are available.   

    *2.2  The boiler shall be furnished as a factory assembled and water tested section assembly with the             

jacket, burner, and controls shipped separately. 

*2.3  The boiler shall be furnished as a factory packaged boiler with jacket, burner, and controls  
         mounted and wired.  Boiler shall be mounted on a steel shipping skid and entire package shall  
         be shrink wrapped. 

    *2.4  Factory packaged boiler shall be factory firetested. 

      2.5  Boiler shall be equipped with a flange mounted flame retention forced draft burner that has been             

designed and tested for a minimum of 82% (Gas fired) and/or 84% (Oil fired) combustion             
efficiency based on I=B=R testing procedure.  

      2.6  The boiler-burner mounting plate shall be lined with lightweight refractory insulation and shall             

have built-in observation port with closure cover.   

      2.7  Boiler sections shall have pin-like projections on each center section, evenly spaced on the              

vertical flue surfaces to extract the greatest possible heating value from the hot flue gases. 

      2.8  Boiler sections shall be surface ground to ensure smooth positive mating surfaces. 

      2.9  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 gasket material which would 
be subject to deterioration due to corrosion or oil based chemicals.  The sections are to be assembled 
with short draw rods. 

    2.10  A gas-tight seal, which is imperative for forced draft boilers, will be achieved with the              

application of a silastic sealant in a finished ground groove between sections.
