POWER VENT FAN AND MOTOR

Code Requirements

Power vent installation must be in accordance with the

following requirements of the National Fuel Gas Code:

•

All portions of the vent system under positive

pressure during operation (on the downstream

outlet side of the fan motor) shall use galva-

nized or stainless steel single wall vent pipe

and be sealed to prevent leakage of flue gases.

•

Provisions shall be made to interlock the

appliance(s) to prevent the flow of gas to the

main burners when the draft system is not

performing so as to satisfy the operating

requirements of the equipment for safe

performance. (Linear spillage switch: p.4)

Installation Restrictions

Power vent motor should be installed as close

to the termination of the vent system as

possible to obtain optimal appliance efficiency

and to prevent flue gas leakage.

"The exit terminals of mechanical vent system shall be

located not less than 7 feet above grade when located

adjacent to a public walkway. The venting system shall

terminate at least 3 feet above any forced air inlet within 10

feet. The venting system shall terminate at least 4 feet

below, 4 feet horizontally from or 1 foot above any door,

window or gravity air inlet into any building."

Also, "The vent terminal shall also not be installed closer

than 3 feet from the inside corner of an L-shaped structure,

or less than 1 foot above grade."

Power venter must be mounted with motor

shaft horizontal to prevent motor bearing

wear.

Power venter housing is single walled. A 6"

clearance from combustible material must be

maintained. (See Figure G)

Position the 5" to 4" reducer pipe on top of the

heater first and then connect a 4" 90º elbow

to begin the horizontal run. Observing this

guideline will help to establish a proper draft.
