INSPECT CHIMNEY  

to verify it is constructed according 

to latest revision of the NFPA 211. Local codes may differ 

from this code and should be checked. Where there is a 

conflict, local code will prevail.  

• Boiler must be installed into chimney which has 

masonry or metallic chimney liner.

• 

Unlined chimney will have leaks that will cause poor 

chimney performance (NO DRAFT), and could result in 

positive pressure in combustion chamber.

• 

Horizontal portions of venting system should not 

exceed 10 feet in length. Horizontal lengths over 10 

feet will have negative effect on chimney performance.

• 

Chimney should extend at least 2 feet above any 

portion of building within 10 feet. See 

Figure #15

. It 

should produce negative draft of .06 to .08 inches of 

water column, (W.C.), as measured with draft gauge 

between boiler and barometric draft control while 

maintaining .02 inch W.C. negative draft in combustion 

chamber. See chart “Chimney or Vent Sizes” for 

recommended chimney or vent sizes. 

• Inadequate draft will cause improper combustion, 

resulting in dirty flue ways and high fuel bills. 

CONNECT FLUE PIPE

 same size as boiler outlet to 

chimney, sloping upward continuously toward chimney 

approximately ¼” per foot. Bolt or screw joints together to 

avoid sag.
If oil fired water heater is vented into same flue as 

boiler, provide separate hole into chimney whenever 

possible. When not possible, use “Y” connection in 

flue pipe, using separate draft regulator for each unit. 

When chimney will not provide adequate draft 

to handle input from water heater and boiler 

simultaneously, wire units so that only one will 

operate at a time, favoring water heater.
