is for use only on top-vented applications. Fireplaces
equipped with millivolt type gas controls CANNOT use
this product.
DO NOT
DISCARD
Note: PVI-SLP-B requires special control system
congurations:
• For IntelliFire® and IntelliFire® Plus models, an
RC100, RC200, or RC300 and PV-IPI-CK control
system is required for installation (except on PRIMO
models). The PV-IPI-CK is sold separately.
• For IntelliFire Touch® models, an IFT-ACM and
IFT-RC400 are required for installation. The IFTRC400, which includes the IFT-ACM, will need to be
purchased if the appliance is not already equipped
with IFT.
• The battery-backup feature cannot be used with
models congured with the PVI-SLP-B.
• The wired wall switch feature cannot be used with
models congured with the PVI-SLP-B.
• An appliance with PVI-SLP-B installed cannot be
operated with battery-backup or a wired wall switch.
A. Components and Service Parts List
Service Parts List
Replacement parts can be obtained from your dealer. Repair
of the Power Vent should only be done by a qualied service
technician.
Note: The battery back-up and wired wall switch feature
of any IPI system are removed when the PVI-SLP-B
power vent is installed. The replace may no longer be
operated with battery back-up and/or a wired wall switch.
The PVI-SLP-B operates on 120VAC, 60Hz electrical service which is supplied at the replace junction box.
IMPORTANT OPERATIONAL NOTE: When the control
being used to run the replace is activated, a 120 second
delay will occur before ignition occurs. This is to allow a
pre-purge by the PVI-SLP-B. If replace does not light
after 135 seconds, refer to the Troubleshooting section of
this instruction for further direction. There will also be a 20
minute post-purge in which the PVI-SLP-B will continue to
run after appliance is turned off.

B. Installation of PVI-SLP-B
1. INSTALLATION PRECAUTIONS
a. This device must be installed by a qualied installer
in accordance with these instructions.
b. Safety inspection of the venting system should
be performed before and after installation of this
power vent. Consult local code ofcials and follow
applicable installation codes.
c. DO NOT INSTALL DAMAGED EQUIPMENT OR
VENT COMPONENTS.
d. Disconnect electrical power supply before making
wiring connections.
e. Venting of more than one appliance in a common
vent system is prohibited.
f. Clearances between the vent pipe and combustible
materials must be maintained at 1-1/2-inch top,
1-inch sides and bottom.
g. All outer pipe joints must be sealed with high tem-
perature silicone. See Section 2.A.
h. The access panel opening must be located such
that access for service and adjustment is available.
The NEC requires a minimum of 30 inches of space
around the opening and 36 inches in front of the
opening to the access panel. Consult ofcials having jurisdiction regarding regional requirements.
CAUTION! Failure to install, operate, and maintain the
power venting system in accordance with manufacturer's
instructions will result in conditions which may produce
bodily injury and/or property damage.
NOTICE: The blower motors present in this Power Vent
will generate sound during operation. The effects of the
increased sound level can be minimized with careful planning during installation of the system. Locating the Power
Vent service access grill in an area remote of immediate
living space will reduce the effects of the added sound
generated during operation.
2. INSTALLATION GUIDELINES
WARNING:RISK OF FIRE AND BURNS. DO NOT
install PVI-SLP-B with the access panel facing upward.
Overheating may occur.
NOTICE: Installation of the PVI-SLP-B in an attic is not
recommended in regions where temperatures reach 0°F
(-18°C) and relative humidity exceeds 60% simultaneously.
Low temperatures and high moisture content may cause
the PVI-SLP-B to freeze.
a. If the PVI-SLP-B is being installed in a conned space
(such as a utility closet, mechanical room or attic space)
with a total volume less than 250 cubic feet, an access
hole with minimum dimensions of 8 inches by 16 inches
will be required directly in front of the access panel.
The recommended access hole size is 12 inches by 17
inches. This size will allow full access to the 11 inch x
16 inch access panel on the PVI-SLP-B. See Figure
3.1. The conned space where the PVI is installed, and
the space to which the access hole opens, must add up
to at least 250 cubic feet. This hole may be covered with
a decorative cover as long as the cover has a minimum
of 50% open air. If the PVI-SLP-B is being installed in
a space greater than 250 cubic feet the access hole is
still required, but a solid cover may be used. This also
applies to a replace chase.
The decorative cover CANNOT be located on an outside
wall that is open to the environment.
b. For installations near loose-ll insulation (such as attics)
a minimum clearance of six inches must be maintained
between the access panel and the insulation.
c. The PVI-SLP-B CANNOT be installed with the access
panel facing upward.
d. The exit termination of mechanical draft systems shall
not be less than seven feet above grade when located
adjacent to public walkways.
e. A mechanical drafting venting system shall terminate at least
three feet above any forced air inlet located within 10 feet.

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-B, consult the Power
Vent diagrams in the Vent Information and Diagrams section of the appliance installation manual. The PVI-SLP-B
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-B): SLP-TVHW, SLP-LPC,
SLP-TRAP, SLP-HHW2, SLP-HRC-SS, SLP-HRC-ZCSS, SLP-TB1. Check installation manual for termination
caps specications.
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.
All outer pipe joints must be sealed with high temperature
silicone (with a minimum of 300 ºF continuous exposure
rating), including the slip section that connects directly to
the horizontal termination cap.
• Apply a bead of silicone sealant inside the female out-
er pipe joint prior to joining sections. See Figure 2.1.
exposure rating) to the outside of connecting 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 ues shall be sealed
in this manner, unless otherwise stated.
B. Vent/Pipe Regulations
WARNING! Risk of Fire!
Maintain minimum pipe length between appliance and PVISLP-B on all models. Combustible materials surrounding
pipe may overheat.
1. A minimum length of venting is required between the
appliance and the PVI-SLP-B. This minimum length
requirement varies for the specic appliance. Refer to
Table 2.1. for requirements for specic models. Once
the minimum length requirement is met, the PVI-SLPB may be installed at any location within the vent run
conguration.
2. A minimum of 18 inches is required between the PVISLP-B and the termination cap to allow room for the
pipe to go through a wall or roof.
3. If PVI-SLP-B 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-B.
4. Total allowable length decreases by 2 ft. for every 1 ft.
of vertical drop.
