discharge opening depends on the roof pitch and must be

supplied with the termination unit.
2. The venting system for these appliances is considered
to be a Special Venting System. The rule in the
Installation Code CAN/CGA–B149 requiring a
minimum vent height of 2ft above any portion of a
building within 10ft does not, therefore, apply. (see
