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-AU, consult the
Power Vent diagrams in the Vent Information and Diagrams
section of the appliance installation manual. The PVLP-
SLP-AU uses SLP pipe (6-5/8 in. (168 mm) connections.
In certain cases, a pipe adapter may be used in the vent
run. The DVP-2SL adapts from 5 in. / 8 in. (127 mm / 203
mm) DVP series starting collars to 4 in. / 6-5/8 in. (102
mm / 168 mm) 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.
B. Vent/Pipe Regulations
WARNING! Risk of Fire!
Maintain minimum pipe length requirement between
appliance and PVLP-SLP-AU on all models. Combustible
materials surrounding pipe may overheat.
1.
A minimum length of venting is required between the
appliance and the PVLP-SLP-AU. 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-
AU may be installed at any location within the vent run
configuration.
2. For every 1 ft. (305 mm) of vertical drop the total allow-
able length must be reduced by 2 ft. (610 mm).
Figure 2.1 Silicone Sealant
All outer pipe joints must be sealed with silicone (with a
minimum of 300 ºF (149
ºC) continuous exposure rating),
including the slip section that connects directly to the hori-
zontal termination cap.
• Apply a bead of silicone sealant inside the female outer
pipe joint prior to joining sections. See Figure 2.1.
OR
• Apply the aluminum foil tape (300 ºF (149 ºC) minimum
continuous exposure rating) to the outside of connect-
ing joint after joining sections. On horizontal pipe runs,
it is recommended that the tape seam is positioned on
the bottom side of the vent pipe.
• 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.
NOTE:
See Table 2.1 for model specific vent
requirements.
