VENT HOOD LOCATION
This section only applies if using a Power Venter to Sidewall vent. If using Power Venter to exhaust the flue gases vertically, skip to
the section titled “POWER VENTER MOUNTING” below.
If possible, locate the Vent Hood on a wall that does not face the direction of prevailing winds. This will diminish the possibility of
appliance 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 Chimneys, Fireplaces, Vents, and Solid Fuel Burning Appliances, (NFPA #211), or 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 1 foot above grade.
• So that the flue gases are not directed so as to jeopardize people, overheat combustible structures or enter buildings, and
• Not less than 2 feet from an adjacent building.
POWER VENTER MOUNTING
The installer must supply plumber’s strap or 1/4” threaded rod with nuts and washers for mounting. The Power Venter may be mount-
ed in any position as long as the shaft of the motor remains horizontal. The Power Venter housing is single wall, 6 inches must be
maintained from all combustible materials. It is recommended that the Power Venter be mounted as close as possible to the point of
termination.
