SIDE WALL VENT HOOD INSTALLATION
1. Use the inside wall plate as a template to mark the hole location. Cut a hole 1 inch larger than the marked hole to
facilitate easy installation (See Figure 4)
2. Center vent hood through the hole from outside. Fasten the vent hood to the outside wall with the appropriate type of
mounting screws.
3. Fasten the wall end plate to the inside wall with the appropriate type
of mounting screws. NOTE: Apply sealant to the outside mounting
plate of the vent hood to prevent leakage.
4. Connect the venter outlet or a properly sized section of vent pipe
onto the inner pipe of the vent hood. Fasten the connection with
three sheet metal screws or equivalent fastening method.
5. Seal the vent hood inlet connection and any other vent pipe joints
on the outlet side of the venter with an approved high temperature
silicone adhesive sealant or equivalent material.
NOTE: Do not enclose the space between the plates on the outside of
the vent hood or between the inner and outer pipe of the vent hood.
This might cause overheating of the wall structure. Local codes might
require fencing around the vent hood outlet.
V
ENTER LOCATION
Install the power venter onto the vent hood inlet or as close to the vent
hood inlet as possible. Always install the venter such that the motor
shaft is horizontal and the pressure switch diaphragm is vertical (See
Figure 5) When venting a draft induced gas fired heating appliance a
barometric draft control must be installed on the vent system between
the appliance outlet and the venter inlet. (See Figure 6)
CAUTION: The power venter should never be installed with the motor shaft in the vertical position. This could allow heat
to be trapped in the venter housing and radiate through the motor possibly causing motor deterioration and premature
failure. Never attach the venter inlet directly to the outlet of the heating appliance. Also, a minimum of 6 inches clearance
between the venter housing and combustible materials must be maintained.
C
ONNECTING VENTER TO THE FLUE PIPE
NOTE: The power venter should be supported in accordance with National Fuel Gas Code Z223.1, Section 7.910 as
follows; A vent connector shall be supported for the design and weight of the material employed to maintain clearances
and to prevent physical damage and separation of joints.
NOTE: For gas fired heating appliances not equipped with a draft hood, a barometric draft control must be installed
between the heating appliance exhaust outlet and the power venter inlet to regulate any draft fluctuations during
operation.
1. Use approved vent connectors to join the heating appliance outlet to the venter inlet securing each joint with sheet
metal screws or equivalent means of fastening when required.
2. Seal all pipe joints on the outlet side of the venter with a high temperature
silicone adhesive or equivalent. Test the vent connections for leaks by
using a soap solution as recommended by the National Fuel Gas Code,
A.N.S.I. Z223.1, Section 4.1.1.
O
PTIONAL GSK-3 EXHAUST GAS SPILLAGE DETECTOR SWITCH INSTALLATION
NOTE: Installation of the GSK-3 secondary safety switch is recommended for
LP and Natural gas fired appliances with a draft hood. This switch will detect
exhaust gas spillage out of the draft hood due to a blocked vent system and/or
inadequate draft during operation. When this switch senses spillage it
interrupts the power supply to the gas valve which terminates the burner
operation.
1. Mount the GSK-3 on the lower edge of the draft hood with the exposed
thermal disk directed into the draft hood (See Figure 7)
2. Route the electrical wires along the heating appliance cabinet within an accepted wiring enclosure in accordance with
the National Electrical Code and any applicable local codes. Keep the wires away from any HOT surfaces.
3. Wire the switch into the low voltage thermostat circuit. Refer to the appropriate wiring diagram in this manual.
4. After installation, check the amperage through the thermostat circuit and adjust the anticipator if necessary.
CAUTION: The GSK-3 is a manual reset switch. Investigate the system thoroughly for the cause of any shut down and
correct the problem before resetting the GSK-3 and restarting the system.
