UC1 UNIVERSAL CONTROL SPECIFICATIONS
INSTALLATION RESTRICTIONS
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 600 0 F. at Power Venter inlet for U.S. or 285 0 C
(550 0 F) for Canadian installations.
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 600 0 F. for U.S. or 285 0 C (550 0 F) for Canadian installations.
7. The appliance(s) may only be installed on the suction side of Power Venter.
8. The UC1 is intended for indoor installation only. Do not mount the UC1 junction box on a heat source that exceeds 140oF.
Examples of improper mounting surfaces include vent pipe, top of heater casing or any place where radiant or convective heat
would cause the junction box temperature to exceed 140oF (60oC).
CAUTIONS
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 National Fuel Gas Code (ANSI Z223.1/NFPA #54), NFPA # 31 Oil Burning
Equipment, the latest edition of the National Electrical Code (NFPA#70) and the Occupational Safety and Health Act (OSHA) when
applicable. Canadian installations must comply with 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 haz-
ardous 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.
