permitted) that re-directs the flue gas away by use of an elbow
or tee, certified to ULC S636 from the adjacent property line

an elbow to the vent portion of the rain cap. A tee attached to
the rain cap could potentially direct the flue gas plume toward
the intake air stream and contaminate the incoming combustion
air for the furnace.
Refer to Figure 44 and Figure 46 for terminations approved for
use in Alberta and Saskatchewan.
