Max Vent length runs with Eco King PP single pipe
Eco King recommends using 3” polypropylene venting, however 2” venting is permitted. Single pipe straight, 45 or
90 terminations are permitted as well. In Table 1.2 the Eco King Boiler vent lengths are outlined.
Table 1.2 Maximum Single Pipe length determination (combined lengths. Exhaust vent pipe should not
exceed ½ these distances, ie. 2” max length is 105 ft, so exhaust should not be longer then 52ft)

General Install Note for single wall venting on Eco King boilers:
You must use only authorized ULC S-636 vent parts in order to maintain a safe, approved system. Do not mix parts
or try to match with other products or use improvised solutions. Do not use any solvents or adhesives with single
wall PP pipe, other than as specified. For horizontal runs always maintain at least a 0.6” per foot rise away from the
boiler to prevent collection of condensate or build-up of heat in the vent. It is recommended to use a bird screen on
roof or sidewall single wall terminations.

reduce to 2” as seen in picture. See vent chart
below for max vent lengths.
