Installation of Vent Pipe
For information on standard procedures for venting the appliance, refer to Section 10.
For the allowable pipe lengths and elbow combinations for this appliance, consult Section 7.I. The PVI uses DVP pipe (8 inch) connections for both the inlet and outlet.
See Section 16 to view the approved termination caps.
All outer pipe joints must be sealed with silicone with a minimum of 300ºF continuous exposure rating, includ- ing the slip section that connects directly to the horizontal termination cap.
•Apply a bead of silicone sealant inside the female outer pipe joint prior to joining sections. See Figure 10.2.
•Only outer pipes need to be sealed. All unit collar, pipe, slip section, elbow and cap outer flues shall be sealed in this manner, unless otherwise stated.
Vent Pipe Regulations
•A minimum of one 90 degree elbow and two feet straight vertical or eight feet vertical venting is required between the appliance and the PVI. Once this requirement is met, the PVI may be placed at any point in the venting configuration.
•A minimum of 18 inches is required between the PVI and the termination cap to allow room for the pipe to go through a wall or roof.
