A. Components and Service Parts List
Service Parts List
Replacement parts can be obtained from your dealer. Re-
pair of the Power Vent should only be done by a qualied
service technician.
NOTICE: The fan motors present in this power vent will
generate sound during operation. The effects of the in-
creased sound level can be minimized with careful plan-
ning during installation of the system.
IMPORTANT OPERATIONAL NOTE: When the wall switch
is being used to run the appliance is activated, a 2 minute
delay will occur before power is provided to the appliance.
This is to allow a pre-purge by the PVLP-SLP-AU. If, after
135 seconds, the pilot and burner do not light, refer to the
Troubleshooting section of this instruction for further direction.
There will also be a 20-minute post-purge in which the PVLP-
SLP-AU will continue to run after appliance is turned off.
NOTE: The battery back-up of any IPI system are re-
moved when the PVLP-SLP-AU power vent is installed.
The appliance may no longer be operated with battery
back-up.
The PVLP-SLP-AU operates on 240VAC, 50Hz electrical
service see Section 4.A for wiring diagram.
NOTE: PVLP-SLP-AU requires special control system
congurations:
• The battery-backup feature cannot be used with
models congured with the PVLP-SLP-AU.
• The wired wall switch feature is required to be used
with models congured with the PVLP-SLP-AU.
B. Installation of PVLP-SLP-AU
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 in. (38 mm)
top, 1 in. (25 mm) sides and bottom.
g. All outer pipe joints must be sealed with silicone
(with a minimum of 300 ºF (149 ºC) continuous
exposure rating). See Section 2.A.
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.
2. INSTALLATION GUIDELINES
a. The exit termination of mechanical draft systems shall
not be less than 7 ft. (2.13 mm) above grade when
located adjacent to public walkways.
b. A mechanical drafting venting system shall terminate at
least three feet above any forced air inlet located within
10 ft. (3.05 m).
c. A PVLP-HS heat shield is available and sold separately
if the PVLP-SLP-AU is installed in an accessible area.
d. If the PVLP-SLP-AU will be installed in a location
where the exhaust housing assembly needs to be
removed for service or maintenance, the pipe must
be installed to allow for a minimum of 18 in. (457
mm) of pipe to be removed at the time of service.
This will allow adequate space to remove the ex-
haust housing assembly.
