Rear Vent Connection, Vertical Rise With Offset, Through The Roof Termination - Valor 534 XAN Installation And Owner's Manual

4.9 Rear Vent Connection, Vertical Rise with Offset,
Through the Roof Termination
See figure 11.
For situations where offset is necessary in an attic to avoid
obstructions or allow useful space.
Adapter #817VAK, one 90º vent elbow, two 45º vent elbows, pipe
lengths, a vertical vent terminal and roof flashing will be required.
Various other ceiling or roof items may be necessary depending on
the particular installation (See venting options section of this
manual).
Note
1. The distance from the roof to the lowest terminal discharge
opening depends on the roof pitch and must be in accordance
with the manufacturer's instructions 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 figure 11a.)
