1. This device must be installed by a qualified professional installer in accordance with these instructions. If improperly installed, a
hazardous condition such as explosion or carbon monoxide poisoning could result.
2. Do not install the Power Venter on incinerators, incinerating toilets, condensing type appliances or solid-fuel burning appliances.
3. The Power Venter shall only be installed on Natural Gas, LP or Oil-fired appliances.
4. Do not install the Power Venter 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.
5. The Power Venter may only be installed on appliances equipped with a draft hood, draft diverter or barometric draft control.
6. The Power Venter shall not be installed where flue gas temperatures exceed 5500F at Power Venter inlet.
FLUE GAS TEMPERATURE VERIFICATION:
A)Consult appliance manufacturer for temperature of gases at the appliance outlet after dilution by draft hood, draft diverter or baro-
metric draft control.
AND
B) Measure temperature of flue gases at the Power Venter inlet at time of installation. Temperature should be measured after
appliance and Power Venter have operated for at least 15 minutes, allowing flue gas temperature to stabilize.
Flue gas temperature at Power Venter inlet must not exceed 2850C (5500F)
7. The electrical load controlled through the Fan Proving Switch must not exceed the electrical ratings marked on the Fan Prover.
8. The appliance(s) may only be installed on the suction side of Power Venter.
Improper installation, adjustment, alterations, service or maintenance can cause injury or property damage. Refer to this manual.
For assistance or additional information consult a qualified installer, service agency, gas or oil supplier.
CAUTIONS
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); Propane Installation Code
(CAN/CGA-B149.2); Installation Code For Oil Burning Equipment (CAN/CSA-B139). Improper installation can create a hazardous
condition such as an explosion, fire, electrical shock or carbon 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. In order to comply with the CSA Listing of the Power Venters the Fan Prover must be wired with the appliance so as to prevent the
main burner(s) from firing if the Power Venter malfunctions or the flue is blocked. It is not safe to use the Power Venter on millivolt
appliances, such as water heaters which employ a combination gas valve/temperature controller, since the Fan Prover can not be
wired as described in this booklet. Millivolt appliances require additional, accessory controls.
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. The installer must verify that the BTU/hr. input of the appliance does not exceed the recommended input of the Power Venter. See
selection table on page 1 of these instructions for sizing information.
6. Flue gas temperatures must not exceed 2850C (5500F) at the Power Venter inlet. Ambient temperatures surrounding Power
Venter must not exceed 400C (1040F). See “Flue Gas Temperature Verification”, item # 6 above.
7. “Safety Inspection Of a Previously Used Appliance” (Page 3) must be performed before installation on previously used equipment.
