INTRODUCTION
The Power Vent Inline (PVI-SLP) is certifi ed for use only on
fi replaces manufactured by Hearth & Home Technologies
with IPI (intermittent pilot ignition) gas controls and is for use
only on top-vented applications. Fireplaces equipped with
millivolt type gas controls CANNOT use this product.
Note: The battery back-up feature of the IPI system is removed
when the PVI-SLP power vent is installed. The fi replace may
no longer be operated with battery back-up.
Installation of the PVI-SLP may be done by a qualifi ed
service technician only. Installation MUST comply with local, regional, state and national codes and regulations.

Hearth & Home Technologies • Power Vent Inline (PVI-SLP) Instructions • 2196-900 Rev. AC • 12/15
The PVI-SLP operates on 120VAC, 60Hz electrical service
which is supplied at the fi replace junction box.
IMPORTANT OPERATIONAL NOTE: When the control
being used to run the fi replace is activated, a 120 second
delay will occur before ignition occurs. This is to allow a
pre-purge by the PVI-SLP. If fi replace does not light after
135 seconds, refer to the Troubleshooting section of this
instruction for further direction. If an RC100, RC200 or
RC300 remote is being used, there will also be a 20 minute
post-purge in which the PVI-SLP will continue to run after
appliance is turned off.

B. Installation of PVI-SLP
1. INSTALLATION PRECAUTIONS
a. This device must be installed by a qualifi ed 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 offi cials 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 offi cials hav-
ing 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 powervent
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
powervent 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 with the access panel facing upward.
Overheating may occur.
NOTICE: Installation of the PVI-SLP 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 to freeze.
a. If the PVI-SLP is being installed in a confi ned 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. See Figure 3.1.
The confi ned 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 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 fi replace chase.
The decorative cover CANNOT be located on an outside
wall that is open to the environment.
b. For installations near loose-fi 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 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, consult the Power
Vent diagrams in the Vent Information and Diagrams section 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-ZCSS, 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.
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 requirement 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 PVISLP 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.
Note: See Table 2.1 for model specifi c vent requirements.
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 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.

B. Vent/Pipe Regulations (continued)
WARNING! Risk of Fire!
• PVI-SLP cannot be installed directly on appliance. The PVI-SLP and combustible materials surrounding vent pipe may
overheat.
• A minimum length run of initial vent pipe is required between the appliance and the inlet of the PVI-SLP. The initial
minimum vent run requirement varies depending on the specifi c appliance and its venting confi guration.
• Some models require DVP Series pipe for the initial minimum vent section directly off the appliance.
