1. “Qualified Installer” shall mean an individual properly trained and licensed.
2. Plan the vent system so that Code required distances are maintained from plumbing and wiring.
3. The Power Venter motor shaft must be mounted horizontally to ensure proper operation of the Fan Proving Switch and prevent
motor bearing wear.
4. Make certain the power supply is adequate for the fan motor requirements. Do not add the Power Venter to a circuit where the
total load is unknown.
5. Flue gas temperatures must not exceed 600°F. at the Power Venter inlet. Ambient temperatures must not exceed 104°F.
Temperatures above this range can cause a fire resulting in property damage, personal injury or death.
6. A safety inspection of an existing appliance must be performed before installation of the Power Venter as outlined in “Natural Gas
and Propane Installation Code, CAN/CSA-B149.1” or “National Fuel Gas Code, ANSI Z223.1 (NFPA 54)”, Appendix H, see
“Safety Inspection of a Previously Used Appliance” below.
1. The installer must read and follow these instructions carefully to assure proper installation and operation of the Power Vent kit.
2. The appliance may only be installed on the suction side of Power Venter.
3. The installer must notify the owner of the maintenance required with the use of the product.
4. The installer must shut off all electricity and gas to the appliance using the appliance circuit breaker/fuse for the electricity and shut
off valve in the supply line to the appliance for the gas before installation of the Power Vent kit.

The following procedure is based on central furnace and boiler installations and it should be recognized that generalized procedures
cannot anticipate all situations. Accordingly, in some cases deviation from this procedure may be necessary to determine safe opera-
tion of the equipment.
a. Perform this procedure prior to any attempt at modifications of the appliance or installation of the Power Venter.
b. If it is determined there is a condition which could result in unsafe operation, shut off the appliance and advise the owner of the
