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.
Never install the power venter so the motor
points down. This will shorten the life. The
minimum clearance to combustibles is 18
inches.
