INSTALLATION RESTRICTIONS
Failure to install, maintain and/or operate the Power Venter in accordance with manufacturer's instructions may result in conditions
which can produce bodily injury and property damage.
The Power Venter must be installed by a qualified installer in accordance with these instructions and all local codes or in their
absence in accordance with the latest edition of The Natural Gas Installation Code (CAN/CGA-B149.1) & The Propane Installation
Code (CAN/CGA-B149.2). Improper installation can create a hazardous condition such as an explosion, fire, electrical shock or car-
bon monoxide poisoning resulting in property damage, personal injury or death.
“Qualified Installer” shall mean (an individual properly trained and licensed) in accordance with local codes or, in their absence, in
accordance with The National Building Code of Canada & The Canadian Electrical Code (CSA Std C22.1).
Disconnect the power supply when making wiring connections or when working around the fan wheel and motor. Failure to do so can
result in electrical shock, personal injury, death or property damage.
1. The Power Venter may only be installed on Natural Gas or LP Gas appliances.
2. The Power Venter may not be installed on incinerators, incinerating toilets, condensing-type appliances or solid-fuel burning
appliances.
3. The Power Venter shall not be installed on an appliance with an automatic valve having a manual opener unless the manual
opener has been rendered inoperative or the automatic valve has been replaced with a valve not equipped with a manual opener.
4. The Power Venter may only be installed on appliance equipped with a draft hood, draft diverter or barometric draft control.
5. The Power Venter shall not be installed where the flue gas temperature exceeds 285oC (550o F). at the Power Venter inlet. Flue
gas temperature verification:
A) Consult appliance manufacturer for flue gas temperature after dilution by the draft hood, draft diverter or barometric draft control.
B) Measure flue gas temperature at the Power Venter inlet after installation. Temperature should be measured after appliance and
Power Venter have operated for at least 15 minutes, allowing the flue gas temperature to stabilize.
6. The Power Venter must be mounted so that the shaft of the motor remains horizontal to prevent motor bearing wear.
7. Power Venter electrical box must be mounted with the Fan Proving Switch in a vertical position.
8. Ambient temperature surrounding Power Venter must not exceed 40oC (104o F).

INSTALLER CAUTIONS
1. Plan the vent system so that the code required clearances are maintained from plumbing and wiring.
2. To prevent personal injury and equipment damage, disconnect power supply when working on Power Venter.
3. Make certain the power supply is adequate for Power Venter motor requirements. Do not add the Power Venter to a circuit where
the total load is unknown.
4. The installer must verify that the appliance on which the Power Venter will be installed is in a safe operating condition. Consult
appliance manufacturer’s Instructions for details.
5. Plan the vent system layout so that the Power Venter is as close to the point of termination as possible. Vent pipe between the
Power Venter and Vent Hood is acceptable. However, all vent pipe connections after the Power Venter discharge will be under
positive pressure during operation and must be sealed with high-temperature caulk or aluminum vent pipe tape to prevent flue gas
leakage into the structure.
