Installation
A
CAUTION
Failure to follow these installation instructions may violate applicable national and/or local codes.
I.
Check vent’ pipe system for leakage. All vent system leaks must be sealed prior to installation of a
power venter.
2.
The vent system must terminate so that proper clearances are maintained as specified in NFGC,
Sec. 7.3.4. and 7.8. (See section titled “Termination of Vent” in these instructions.)
3.
A vent system incorporating a
VHl
Series Vent Hood should not exceed 550°F.
4.
Termination of a sidewall vent system with a device other than the
VHl
Series Vent Hood could affect
system performance and result in a possible safety hazard.
5.
Plan the vent system layout to avoid the possibility of accidental contact with concealed wiring or
plumbing inside walls.
6.
Installation must be done according to national and local codes.
7.
The setting of the venting proving switch is factory set and should not be adjusted.
8.
The venter should be mounted as close to the vent terminal as is practical.

For Power Vent Kit 4:
Attach the enclosed template on Page 6 to interior of the wall the Vent Hood will be penetrating.
Using a
l/2”
drill bit, drill two pilot holes where noted on the template. The drill bit must be long
enough to penetrate to the building exterior.
Attach template to the building exterior aligning the pilot holes noted on the template with the holes
drilled in step A.
Using a reciprocating saw, cut a hole through the building siding, wall board, etc., following the appro-
priate lines of the template.
Slide the Vent Hood through the opening and fasten to exterior wall using screws provided.
Once Power Venter and vent pipe are completely installed and secured, apply a bead of caulk
between the Vent Hood flange and exterior of building.
For Power Vent Kit 5:
Use inside wall cover plate as a template to mark a hole at termination point on the wall. Cut hole
112”
larger than cover plate to facilitate installation.
Slide Vent Hood through opening. Fasten to exterior wall using screws provided.
Install cover plate and fasten to the inside wall with four screws.
Once Power Venter and vent pipe are completely installed and secured, apply a bead of caulk
between the Vent Hood flange and exterior of building.

a)
b)
Disconnect power supply before making wiring connection to prevent electrical shock and equipment
damage.
All wiring must comply with applicable national and local codes and ordinances.
When wiring is completed check all components by running system through at least three heating
cycles.
Flue temperature must not exceed 550°F at power venter inlet.
Power Venter damper must be adjusted to assure appliance
efficiency
is not affected. See heading
“Damper Adjustment”.
Failure to install, maintain and/or operate the power venter in accordance with the manufacturer’s
instructions may result in a safety hazard or conditions which can produce personal injury and/or
property damage.
Maintain 6” clearance to combustibles from power vent housing.
Use only single wall metal or type ‘B’ vent.
If you have any questions regarding proper installation of the Power Venter or safety precautions, call
the manufacturer of the Power Venter
(600-2554206).
Verify Power Venter model selection from chart on page
1.
Connect outlet of Power Venter to vent terminal, suspending the Power Venter to joists, or other ade-
quate support means, as shown in following diagram. NOTE: Venter outlet may be horizontal or verti-
cal as long as the oil holes are level or point upward.
VENTER MUST BE MOUNTED WITH MOTOR SHAFT HORIZONTAL.
3
NOTE: Vent pipe transitions, where necessary,
must be gradually tapered.
To facilitate installation and reduce vibration, the vent kit includes 2 mounting brackets, 2 rubber isolators
and 2 rubber grommets. One of the brackets may be used temporarily as a “third hand” to support the
venter while positioning it for permanent installation.
When installing the Power Venter for horizontal mount, install one of the brackets to the electrical box
using the nut/screw provided, install the other bracket to the damper rod as shown below. When installing
the Power Venter for vertical mount, only one bracket is needed. This bracket should be mounted to the
motor mount as shown below.
NOTE: Whether horizontal or
vertical mount, the motor shaft
must be horizontal.
c)
Connect the inlet of the Power Venter to the Draft Hood of the appliance outlet using suitable vent pip-
ing and adapter if required (not supplied in the vent kit). This Power Venter can be installed with a
maximum of 50 linear feet of single wall vent pipe including the vent terminal. Deduct 10 feet of vent
pipe for each 90 degree elbow and 8 feet for each 45 degree elbow to determine the total amount of
linear vent pipe allowed for the installation.
d)
It is recommended all vent connections should be sealed to prevent leaks after installation using high
temperature silicone sealant.
e)
Wire
Power Venter according to appropriate circuit appearing below. Unit must be grounded, all wiring
is to comply with applicable electrical codes. Wring must be protected by overcurrent protection
(fuses or circuit breakers) rated 15 amperes or less. Extreme caution must be exercised to ensure
that wiring does not come into contact with any heat source.
4
Wire the Power Venter to the circuit appearing below. Venter must be gmunded. All wiring is to comply
with applicable electrical codes. Wiring must be protected by fuses or circuit breaker rated
16
amps or
less. Extreme caution must be exercised to ensure that witins does not contact anv heat source.

TO AL’ MODELS
1.
Supply 115/60/l power to the venter supply connections.
2.
Locate the wire harness that connects to the flue damper motor. This consists of a red, gray, yellow
and blue wire connected to a Molex 4 pin plug.
3.
Cut the red and gray wires approximately 3’ before the plug and strip
3/8’
insulation
Tom
all wire
ends created by cuts.
4.
Connect the red wire from the water heater to the red wire on the venter cable.
5.
Connect the red wire from the Molex plug to the green wire on the venter cable.
6.
Join the gray wire from the water heater to both the gray wire from the Molex plug and the white wire
on the venter cable.
7.
Affix new wiring label over existing wiring label on heater.
Slowly close damper on venter discharge until flue gas spillage is detected
at
the
draf?
hood. Open
damper just enough to eliminate spillage. Lock damper in place by means of locknut on opposite side of
housing.
Operation
1.
On a call for heat from the control thermostat, 24 volts is applied to the actuating terminal of the
damper motor.
2.
When the damper motor is fully open, power is applied to the 24 volt relay of the venter.
3.
When the venter motor has started, the air proving switch allows the main gas valve to open.
4.
When the thermostat is satisfied, power is removed from the actuating terminal of the damper motor.
5.
As the damper begins to close, power is removed from the venter relay, the venter shuts down, the air
proving switch opens, and the gas valve closes.
