1. GENERAL INFORMATION
1.1 FUNCTION
The IPVB Power Venter is intended for use as a true in-line
draft inducer. It can be installed in-line in the vertical or
horizontal section of a chimney or stack. It is specifically
designed for applications where reliable and efficient
operation, low noise level, low energy consumption, variable
speed and compact design are critical.
The IPVB is for use with condensing and non-condensing
appliances at flue gas temperatures of 575°F (302°C) for
continuous operation.
Typical uses are mechanical venting of gas-fired or oil-fired
boilers and water heaters. The IPVB is for indoor or outdoor
installation where ambient temperatures are in the range of
-40°F to 122°F (-40°C to 50°C).
The IPVB Power Venter is an efficient, high-temperature
ventilator with backward-inclined impeller. The ventilator
housing is made of stainless steel and equipped with an
energy-efficient, totally enclosed, variable speed motor, which
is mounted outside the air stream. The design is a Type B,
Spark Resistant Construction. The motor and impeller is a
complete assembly (drive unit) that can be removed from the
fan housing without removing the fan from the stack system.
The stack connections are of the flanged connection type
and fit most commercial pre-fabricated chimney systems.
The fan is typically installed hung from ceiling mounting
brackets to support the weight. The IPVB model is approved
for temperatures up to 575°F (302°C). The IPVB is a
component in the ENERVEX CASITM, Chimney Automation
System.
The housing is made of 316L stainless steel. The impeller
is of the backward inclined type made of cast aluminum.
Commercial grade, totally enclosed (TEFC), variable speed,
Class A insulated motor with sealed and permanently
lubricated bearings. Thermal overload protection.
The IPVB Power Venter should only be used with appliances
operating on Natural Gas, LP-Gas/Butane or fuel oil (#2
through #6). It should never be used with incinerators,
incinerating toilets or solid-fuel burning equipment. The
temperature of the flue gases going through the Power
Venter should not exceed 575°F (302°C).

3. MECHANICAL INSTALLATION
3.1 GENERAL
WARNING
Failure to install, maintain or operate the
IPVB Power Venter in accordance with the
manufacturer’s instructions may result in
conditions which can produce bodily injury and
property damage.
The IPVB must be installed by a qualified installer in
accordance with these instructions and all local codes, or in
their absence, with the latest edition of The National Fuel Gas
Code (NFPA54/ANSI223.1), NFPA 211, NFPA 31 or Canada
CAN/CSA-B149.1-05 National Gas and Propane Installation
Code when applicable. The IPVB must be mounted so the
clearance to combustibles is at least 18 inches.
Preferably, the IPVB should be installed as close to the
termination as possible. It can also be installed near the outlet
of a heating appliance in the breeching itself. In addition,
it can be used for sidewall vented applications where it
discharges through a wall. A drain is provided with the IPVB
to be installed by the user.
The IPVB is for indoor and outdoor installation. Unless
installed adjacent to the wall it is discharging through, the
chimney material used on the discharge side must be airtight/
pressure rated. Traditional gas vent (B-vent) is not considered
pressure rated or airtight. The vent pipe must be installed
and supported according to the chimney manufacturer’s
instructions and/or in accordance with NFPA54, NFPA211
and Canada CAN/CSA-B149.1-05. The IPVB collars fit most
commonly available vents and stacks.
RS 14/16: Before mounting, the transport safety device on
the hinges must be removed.
3.2 POSITIONING
Acceptable fan positions are shown at right in Fig. 2. If
mounted horizontally, ENERVEX recommends that the motor
be positioned to the side as shown in Fig. 2, position B. The
IPVB must be mounted to provide clear and easy access to
the motor and impeller assembly.
NOTE: If the IPVB is mounted in position B or C, a drain must
be installed as described in Section 3.3.
*If the IPVB is oriented as shown in position C, the resulting
axial load on the bearings may shorten the life of the motor.
WARNING
Never install the power venter so the motor
points down. This will shorten the life. The
minimum clearance to combustibles is 18
inches.

4.1 GENERAL
DANGER
Turn off electrical power before servicing.
Contact with live electric components can
cause shock or death.
NOTICE
If any of the original wire supplied with the
system must be replaced, use similar wire
of the same terperature rating. Otherwise,
insulation may melt or degrade, exposing bare
wire.
All wiring must be in compliance with the local codes or in
their absence, the National Electric Code, NFPA70. All wiring
should be appropriate Class 1 wiring as follows: installed in
rigid metal conduit, intermediate metal conduit, rigid nonmetallic conduit, electrical metallic tubing, or be otherwise
suitably protected from physical damage.
IPVB models operate at different voltages, please pay
attention to the wiring details. IPVB 300 operates at
1x120VAC while all other models can operate at 3x208-230
VAC or 3x440-480VAC. This is indicated by the terminal wire
configuration in the motor junction box. See Section 4.3.
4.2 WIRING DIAGRAM - IPVB 300
Power Venter and motor specifications can be found under
“Section 2.1 Dimensions and Capacities”. The power venter
is equipped with a variable speed motor. The diagram below
shows a typical wiring diagram for a IPVB 300 utilizing a Fan
Speed Control.

Power Venter and motor specifications can be found under
“Section 2.1 Dimensions and Capacities”. The power
venter is equipped with a variable speed motor. Fig. 11
below shows a typical wiring diagram utilizing a Variable
Frequency Drive (adjusting the speed is possible). If it is not a
requirement that the speed can be adjusted, a motor starter
should be installed in lieu of the VFD, if required by local
codes.
After wiring, make sure the motor is rotating in the proper
direction. This is marked on the motor end cover. If the
rotation is incorrect, swap the two wires going to the motor
terminals, U1 and W1 as shown in paragraph 4.6 . (This does
NOT apply to the IPVB 300).
4.4 INSTALLING A PROVEN DRAFT SWITCH
A safety system must be interlocked with the appliance to
prevent flue gas spillage from the appliance and/or leakage
through the fan or stack. The safety system should utilize a
Proven Draft Switch (PDS-1) to ensure a negative pressure
in the stack at all times. The device must be interlocked
with the heating appliance(s) so it shuts down in case of
insufficient draft, fan failure or power failure. Please refer to
the PDS Installation Manual for wiring instructions.
If the installation includes an EBC12* or EBC 31 Fan Control,
a PDS-1 may not not required as the function is integrated in
the control.
We recommend to interlock the appliances with the
controller.
*The EBC12 can only interlock one appliance.
For more information, please consult ENERVEX.

4.6 CHECKING AND CHANGING ROTATION OF IPVB
350, 400 AND 500
To check the rotation of the impeller, it is necessary to be
able to see the impeller or the rotation of the cooling vanes at
the end of the motor housing.
Looking through the outlet of the fan, the rotation of the
impeller should be clockwise as shown in Fig. 13. Correct
rotation direction is also indicated by an arrow on the motor
end cover. There are holes in the end cover that allow you
to see the cooling vanes, but it is difficult to see the rotation
unless the fan is running very slowly.
It is possible for the fan to operate with improper rotation.
However, the fan will only provide 25-30% of full capacity.
Improper rotation damages the motor, and causes various
electrical faults at the Variable Frequency Drive.
Fan rotation can be changed by swapping the two phase
wires as shown on the wiring diagram in Fig.14.
DANGER
Turn off electrical power before servicing.
Contact with live electric components can cause
shock or death.
Fig 13
Fig 14

3002600 08.17
5. STARTUP AND CONFIGURATION
5.1 GENERAL
The purpose of this fan is to ensure safe venting for a single
or multiple appliances. This can be performed via modulation,
or through a single speed where modulation is not required.
This is accomplished by starting a chimney fan/power venter
when the appliance “calls for heat”, and stopping the fan
when the “call for heat” demand has been satisfied.
5.2 SYSTEM TESTING
1. Check the line voltage with the motor plate rating.
2. Determine if the impeller is running free, and has not
been subjected to misalignment in shipping or during
installation.
3. Apply power and check that the impeller is rotating in
the direction of the arrow on the side of the fan housing
(does not apply to IPVB 300). All IPVB fans run in a
clockwise direction when viewed from
the fanoutlet or when looking down at the motor.
4. Switching any two phases between the fan and the power
source (VFD is the power source if installed) will reverse
rotation (except on IPVB 300).
5.3 ADJUSTING FAN SPEED
Start all heating appliances connected to the chimney with
the fan installed.
1. If operating with fixed speed, set the fan speed control or
the Variable Frequency Drive to the speed where no
spoilage is experienced anywhere in the system.
2. If operating with variable speed, a modulating control
(EBC 12 or EBC 30) is required. Follow the instructions in
the control’s installation manual.
5.4 TESTING SAFETY SYSTEM
Adjust the setting of the Proven Draft Switch or other device
used.
Start the heating appliance and the fan, and make sure the
safety device is functioning. Turn the fan off. Shortly after, the
appliance should shut down.

6. MAINTENANCE AND TROUBLESHOOTING
REMOVE (4) HEX NUTS BEFORE
REMOVING MOTOR/IMPELLER ASSEMBLY.
6.1 GENERAL
The power venter is designed for prolonged use, and no
regular maintenance is required. It should be inspected
periodically (at least once a year), and cleaned, if needed.
This specifically applies in case it is being used with fuel oil.
The power venter is designed to make this an easy task. The
front part of the venter has the motor and impeller mounted
on it, and it slides out to provide easy access.
6.2 PREPARING THE POWER VENTER FOR
CLEANING
Referring to Fig. 15 below, follow these steps to open the
venter so it can be cleaned and inspected:
1. Remove the four hex nuts holding the motor mounting
plate to the housing
2. Motor and impeller assembly can be lifted out of the
housing. See table listing weights for each model.
3. Clean the impeller and inside of the housing as needed.
4. Replace the motor and impeller assembly and tighten hex
nuts to secure motor plate.
