HOW TO REMOVE THE GUARDIAN POWERVENT GAS CONTROL
1. Turn gas valve to OFF. Shut off the
gas to the unit. Shut off the water
supply to the unit. Remove jacket
door. Remove gas line.
2. Connect a garden hose to the drain
valve and open the drain valve. Lift
the silver lever on the T&P valve to
vent the unit and allow the tank to
drain thru the drain valve.
3. Unscrew the pilot supply tube (7/16”)
and the main gas supply tube (3/4”),
and remove the ignitor wire from the
gas control valve.
4. Disconnect all wiring and Molex
connectors from the gas valve.
5. When the water is drained, unscrew
the gas valve. It should loosen

at it. Use a 10-12 inch threaded black
pipe as a cheater bar if needed.
6. Put plenty of pipe dope (or other
sealer required by local code) on the
threads of the valve. Install gas
control.
