3. Install the furnace on the suction side of the Power Venter.
4. Notify the homeowner of the maintenance required with the use of the product.
5. Verify that the furnace safety controls are in good operating condition before installation of the *GPAK-1TR*.
6. No additional appliances may be vented with the furnace by the *GPAK-1TR*.
7. The Power Venter must not be installed into any portion of a vent system which serves appliances other than the one vented by the *GPAK-1TR*.
8. Shut off all electricity and gas to the furnace using the furnace circuit breaker/fuse for the electricity and turn off gas valve in the
supply line to the furnace before installation of the *GPAK-1TR*.
9. Check the limit and fan control for proper operation. Limit control operation can be checked by blocking the circulating air inlet or
temporarily disconnecting the electrical supply to the blower motor and determining that the limit control acts to shut off the main
burner gas.
VENT HOOD LOCATION
If possible, locate the Vent Hood on a wall that does not face the direction of prevailing winds. This will diminish the possibility of
furnace interruption during periods of extreme winds.
If possible, locate the Vent Hood no closer than 3 feet from an inside corner of an L-shaped structure.
CODE REQUIREMENTS
Terminate the vent system so that proper minimum clearances are maintained as cited in the latest edition of the National Fuel Gas
Code (NFPA # 54) and the latest edition of NFPA #211, as follows:
• Not be less than 7 feet above grade when located adjacent to public walk ways.
• At least 3 feet above any forced air inlet located within 10 feet.
• At least 4 feet below, 4 feet horizontally from or 1 foot above any door, window or gravity air inlet into any building.
• At least 12 inches above grade.
• Ensure flue gas termination is not directed so as to jeopardize people, overheat combustible structures or enter buildings.
• Not less than 2 feet from an adjacent building.
• The vent shall not terminate over public walkways or over an area where condensation or vapor could create a nuisance or hazard.
• Caulk all cracks, seams and joints within 6 feet horizontally and above and below vent.
