1. Product Information
1.1 Function
The RSV chimney fan is intended for use as part of a chimney, stack or venting system. The
fan is designed to withstand the high temperatures associated with combustion, and can be used with natural gas,
  LP-gasandoil-redheatingappliancesystemswhereuegasesdonotexceed575oF (300oC) for intermittent
operation and 482oF(250oC) for continuous operation. It is approved for use with category I, II, III and IV appliances.
The RSV fan may be installed on a traditional vertical chimney system, or as part of a side-wall vented system.
Always install the fan at the chimney termination point.
The use of a chimney fan is not restricted to any type of chimney, because the fan creates a
negative pressure (below atmospheric) in the chimney system. However, always follow the heating appliance
  manufacturer’sinstructionsregardingspecicventingrequirements.
The fan is designed to prevent draft problems by creating mechanical draft in chimney and stack systems. It can
  alsobeusedtoincreasethecapacityandefciencyofsuchasystem.
The fan housing is made of heavy cast aluminum and can be opened for easy cleaning. The RSV 200-450 have a
backward inclined impeller. It is made of cast aluminum and has permanently attached balancing weights.
The motor is a direct drive, variable speed, class H insulated, high temperature motor. It has permanently
lubricated and sealed ball bearings and is maintenance free.
Installations must conform to the requirements of the authority having jurisdiction. Where required by the authority
having jurisdiction, the installation must also conform to the NFPA 31, 54 or 211.
All electrical wiring must be in accordance with the requirements of authority having jurisdiction or, in absence of
such requirements, with the National Electrical Code, NFPA 70.
RSV is tested and listed to UL Standard 378 for Draft Equipment and CAN3-B255-M81 for
Mechanical Flue-Gas Exhausters (ETL Report 514733).
The RSV Fan is a listed component in the CASV, Chimney Automation System. The fan is approved for
use in dryer venting systems as well.

3.7 Installation for High Temperatures
 Ifthefanisusedforapplicationswheretheuegastemperaturesexceed482°Fattheueexit,dilutionairisrequired.
 Dilutionairallowscoolairtodilutethewarmuegases.Thebestwaytointroducedilutionairisthroughabarometric
damper or draft hood mounted in the chimney system between the appliance outlet and the fan outlet. When
introducing dilution air, the fan capacity is reduced and a larger fan may be required.
3.8 Installation of Proven Draft Switch (PDS)
A safety system must be interlocked with the appliance(s). The safety system could utilize a Proven Draft Switch, a
 thermalswitchoraowswitch.
 Thedevicemustbeinterlockedwiththeheatingappliancesoitshutsdownincaseofinsufcientdraft,fanfailure 
or power failure. Please refer to the PDS-1 Installation Manual if this control is used. For more information on
alternative safety systems, please contact ENERVEX, Inc. Fig. 8 shows the location of the stack probe used with

5. Startup and Conguration
5.1 System Testing
 • Checkthelinevoltagewiththemotornameplaterating.
 • Checkthatthetransportsecuringdeviceholdingthemotorshaftandimpellerinplacehasbeen  
removed.
 • Determineiftheaxialvaneorimpellerisrunningfreeandhasnotbeensubjecttomisalignmentin 
shipping or installation.
 • Applypowerandcheckthattheaxialvaneorimpellerisrotatinginthedirectionofthearrowontheside 
of the top motor cover (RSV400/450 only). All RSV fans run in a clockwise direction when
viewed from the top.
 • Switchinganytwophasesinthejunctionboxwillreversetherotation.
5.2 Adjusting Fan Speed
 • Startallheatingappliancesconnectedtothechimneywiththefaninstalled.Setthefanspeedcontrol 
to the speed where no spillage is experienced anywhere in the system.
5.3 Testing Safety System
 • AdjustthesettingoftheProvenDraftSystemorotherdevice.
 • Starttheheatingappliancesandthechimneyfantomakesurethesafetydeviceisfunctioning.Turn 
the fan off. After less than 1-2 minutes all appliances should be shut down.
Make sure the fan is running in the correct direction; the fact that the fan blows is no
guarantee it is doing so. Running the fan in the wrong direction over a longer period of
time will damage the motor.
It is important that the installation, start-up and system testing procedures are followed.
Failure to do so may have a major negative impact on motor expectancy.
Fig. 11
The motor wiring terminals in Fig. 11 show default jumper
positions for 3x208-240VAC operation.
If the application requires 3x440-480VAC operation, the
jumper positions must be changed according to Fig. 12.
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.
Fig. 12
RSV 400-450 can operate at either 3x208-230 VAC (default) or 3x440-480 VAC.
