vent work.
The size of the vent should be uniform.•
Use no more than three 90° elbows.•
Make sure there is a minimum of 24” (61 •
cm) of straight vent between the elbows if
more than one elbow is used.
DO NOT install two elbows together.•
The length of vent system and number of •
elbows should be kept to a minimum to pro-
