IN THE EVENT OF PILOT OUTAGE
1. Push the reset button in the center of the Linear Limit spillage sensing located on
the draft hood on the top of the water heater.
2. Turn the gas pilot knob at the top of water heater gas valve to “OFF” position.
WARNING: Gas pilot knob MUST REMAIN IN “OFF” POSITION FOR FIVE
MINUTES BEFORE PILOT IS RE-LIT. Perform steps 3 & 4 while waiting.
3. Visually verify that there is 115 volt power established to the Power Venter.
Check fuse or circuit breaker, wall plug and electrical connections.
4. Visually verify that all electrical connections of control cord circuit are intact.
5. Follow water heater manufacturer’s re-lighting instructions attached to water
heater or located in water heater owner’s manual.
USER NOTE:
Since the Power Venter cannot operate during a power outage, the safety interlock controls are designed to prohibit gas flow to the
water heater. Follow the above procedures and water heater manufacturer’s instructions for relighting the pilot when power has been
restored.
