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).
