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 PVI-SLP, consult the Power
Vent diagrams in the Vent Information and Diagrams sec-
tion of the appliance installation manual. The PVI-SLP
uses SLP pipe (6-5/8 inch) connections for both the inlet
and outlet.
The following termination caps are available for use with
the power vent inline (PVI-SLP): SLP-TVHW, SLP-LPC,
SLP-TRAP, SLP-HHW2, SLP-HRC-SS, SLP-HRC-ZC-
SS, SLP-TB1. Check installation manual for termination
caps specifi cations.
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.
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.
SLP pipe may be used on the termination side of the PVI.
B. Vent/Pipe Regulations
WARNING! Risk of Fire!
Maintain minimum pipe length between appliance and
PVI-SLP on all models. Combustible materials surrounding
pipe may overheat.
1. A minimum length of venting is required between the
appliance and the PVI-SLP. This minimum length re-
quirement varies for the specifi c appliance. Refer to
Table 2.1. for requirements for specifi c models. Once
the minimum length requirement is met, the PVI-SLP
may be installed at any location within the vent run
confi guration.
2. A minimum of 18 inches is required between the PVI-
SLP and the termination cap to allow room for the pipe
to go through a wall or roof.
3. If PVI-SLP is installed in the vertical position, a minimum
of two 90 degree elbows and two feet of pipe is required
between the appliance and the PVI-SLP.
4. Total allowable length decreases by 2 ft. for every 1 ft.
of vertical drop.
Figure 2.1 High Temperature Silicone Sealant
All outer pipe joints must be sealed with high temperature
silicone (with a minimum of 300ºF continuous exposure
rating), including 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 fl ues shall be sealed
in this manner, unless otherwise stated.
Note: See Table 2.1 for model specifi c vent requirements.
