Burnham V11H Boiler Ficha De Características

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

application of a fiberglass rope gasket and silastic sealant in a finished ground groove between 
sections.    

    2.11  Washout tappings shall be provided in both the front and back boiler sections.  Blowoff tapping       
 

shall be provided in the back boiler section. 

  *2.12  The front section of the boiler shall have (2) ½” gauge glass tappings for steam; thus eliminating   

the need for a separate external type water column. 

  *2.13  The boiler shall be furnished with a 1-1/2” crown inspection/washout tapping on each side of each 

section.  Each tapping shall be furnished with a brass square head plug.      

  *2.14  Water boiler sections shall be individually hydrostatically tested for 80 psi water working pressure in 

accordance with ASME Code Section IV. 

  *2.15  Steam boiler sections shall be hydrostatically tested in accordance with ASME Code Section IV.                  

    2.16  Boiler shall have individual cleanout openings between sections covered with insulated steel              

covers to insure a gas-tight seal.  

    2.17  Boiler flue canopy shall be constructed of heavy gauge aluminized steel and shall be concealed   
 

under an insulated steel boiler jacket. 

    2.18  The boiler flue connector shall be (rear)(top) outlet and securely fastened and sealed to the             

canopy and shall contain a lock-type adjustable damper with test tapping. 

    2.19 The boiler jacket shall be constructed of heavy gauge steel (20 ga.) with 1” 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 removable side panels so that the 
jacket can be removed for cleaning without removing any screws or disturbing the system piping. 

    2.20  The boiler shall be furnished with a rear flame observation port (spring loaded pressure relief   

 

door with built-in observation port - optional). 

   *2.21 Water boiler trim shall include a 3-1/2” round pressure-temperature gauge with separated scales for 

pressure and water temperature.  In addition, an ASME approved safety relief valve shall be 
furnished sized to exceed the boiler gross output capacity and shall be factory set to relieve pressure 
at (30) (50) (80) psi. 

   *2.22 Steam boiler trim shall include a 3-1/2” round steam pressure gauge with internal siphon device. A 

water level gauge glass shall be furnished with a flush and drain valve in bottom connection. In 
addition, an ASME approved safety valve shall be furnished with side outlet porting set to relieve 
pressure at 15 psi.  The safety valve shall be sized to exceed the gross output of the boiler. 

    

*(NOTE TO SPECIFIER:  Tankless heaters for domestic water supply are available for the V-11H steam 

or water boilers.  Because of the wide variety of ratings (8 to 72 GPM), dependent on boiler size, 
please refer to current V-11H installation manual or trade price book for exact quantity, heater 
number rating and control arrangements available.  If a tankless heater is desired, we suggest the 
following paragraph be added.)  

   

*2.23 The boiler shall include _______ (quantity) tankless heater(s) number V11-2 with a total continuous 

draw rating of _______ GPM of water raised from 40° to 140°F with 200°F boiler water

 

temperature.
