WARNING!  

Do not locate intake or exhaust terminations 
directly above a walkway; dripping of conden-
sation can cause icing of the walking surface.

The vent should extend at least three (3) feet above 
the roof, or at least two (2) feet above the highest part 
of any structure within ten (10) feet of the vent.  

To prevent the possible re-circulation of flue gases, 
your vent designer must take into consideration such 
things as prevailing winds, eddy zones, building 
configurations, etc.  P-K can not be responsible for 
the effects such adverse conditions may have on the 
operation of the boilers.  Dimensions listed above or 
those illustrated are minimum, and may or may not be 
sufficient for conditions at a specific job site. 

A tee must be of approved design and adequate 
capacity. 

 

The venting instructions in this manual apply to a 
single boiler.   

Venting systems for multiple boilers must be 
designed by qualified professionals and verified by 
the stack manufacturer.  The venting system must 
prevent backflow of exhaust gas through idle 
boilers which are not operating.
