Vent Information and Diagrams
A. Installation of Vent Pipe
For information on standard procedures for venting the
appliance, refer to the "Vent Information and Diagrams"
section of the appliance installation manual.
For the allowable pipe lengths and elbow combinations for
an appliance utilizing the PVLP-SLP, consult the Power
Vent diagrams in the Vent Information and Diagrams sec-
tion of the appliance installation manual. The PVLP-SLP
uses SLP pipe (6-5/8 inch) connections.
In certain cases, a pipe adapter may be used in the vent
run. The DVP-2SL adapts from 5 in. / 8 in. DVP series
starting collars to 4 in. / 6-5/8 in. SLP series vent pipe. A
DVP-SLP24 may also be used to transition from a DVP to
SLP pipe when using this cap.
Either SLP or DVP venting may be used throughout the
vent run except on certain models that require DVP pipe.
See Table 2.1. Refer to Section 2.B for more information
regarding venting regulations.
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 2.1.
• 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.

WARNING! Risk of Fire!
Maintain minimum pipe length requirement between
appliance and PVLP-SLP on all models. Combustible
materials surrounding pipe may overheat.
1. A minimum length of venting is required between the
appliance and the PVLP-SLP. This minimum length
requirement varies for the specific appliance. Refer to
Table 2.1. for requirements for specific models. Once
the minimum length requirement is met, the PVLP-SLP
may be installed at any location within the vent run
configuration.
2. For every 1 ft. of vertical drop the total allowable length
must be reduced by 2 ft.
Note: See Table 2.1 for model specific vent requirements.
