Burnham Series V11 브로셔

The cast iron sectional design of the V11 boiler makes it easy to
maneuver through doorways and into the boiler room. In addi-
tion to being shipped as loose sections, the boiler is available 
with factory-assembled sections or as a completely packaged 
and fire-tested unit.

  Hassle-free Section Assembly

 

V11 boiler sections have reinforced lugs that are used

  to assemble the sections with individual draw rods   
  resulting in fast, strain-free assembly. 

 

 

 

The sections can be assembled using two common  

  toolsÑ a 3/4" drive ratchet with a 1-1/16" deep socket 
  and wrench.

 

The sections are surface ground to ensure

  smooth surface mating. An elastic sealant and fiberglass   
  rope are used on all section joints for a completely sealed   
  and pressure-tight assembly.

•

  extensive Testing Methods

 

Each boiler section is hydrostatically tested at 2-1/2 times

 the rated working pressure at the foundry. Factory-

  assembled sections are tested a second time at 1.5 times the  
  rated  working pressure.

•

  Rear or Top Venting

 

As a forced draft boiler, the V11

  provides optimum draft for controlled  

 

  efficiency, eliminating the need for  
  high chimneys or induced draft fans.  
 A unique feature of the V11 boiler
  is that it can be vented from the
  rear or the top. This enables easy
  chimney or sidewall venting for
  maximum installation flexibility.
  Top outlet venting saves floor space
  and reduces installation time and  

 

  materials.  A plugged tapping is   
  provided to take flue outlet pressure  
  readings.

Available in twenty sizes with gross output ratings from 
667 to 4551 MBH, the V11 Series is commonly used in
schools, hospitals, and other large commercial applications 
where comfort and reliability are critical. The product meets 
the energy efficiency requirements of ASHRAE 90.1 with
combustion efficiencies up to 85%.
Cast iron construction, ease of assembly, two venting options, 
and stringent testing methods make the V11 Series boiler by
Burnham Commercial your commercial heating solution.

Burnham CommercialÕ s unique 

BC25-HSi cast iron formula has
an extremely high silicon content, 
making it stronger and more 
flexible than the iron used in 
competitor's boiler sections. It offers 
better thermal shock resistance and 
greater heat transfer capabilities 
than other cast iron products. 

BC25-HSi's properties allow Burnham Commercial to

maintain the highest level of quality from start to finish, and 
provide a product that is optimized 
for hydronic heating applications

  Manufactured with Quality

 

Cast iron sections are produced at  

 

 Burnham Foundry LLC in Ohio,  
  ensuring quality and availability of  
  boiler sections.

•

  Cast Iron nipple Difference

 

V11 sections are held together

  using cast iron nipples, which 
  are well known as being of the   

 

  highest standard for boiler 
  construction. Unlike gaskets used  

 

  by many other boiler 
  manufacturers, cast iron nipples are impervious to flue 
  gases, oils, petroleum-based chemicals and other   
  contaminants, which means fewer costly repairs and a  
  longer lasting boiler.
