Gemini™ Twin-Fuel Gas-Fired Boiler

1.Close main (natural gas and propane) and pilot shutoffs.

2.Turn the On/Off switch to "OFF" position.

3.Wait 5 minutes.

4.Open main (natural gas and propane) and pilot shutoffs.

5.Turn the On/Off switch to "ON" position.

6.Push reset button on flame safeguard programmer control.

7.Push reset on low gas pressure switch (and high pressure gas switch if applicable).

8.Check to be sure that pilot has been established.

The controller will now complete the automatic firing sequence.

5.2.2 Normal Shut-Down Procedures

1.Close all manual gas shutoffs.

2.Turn off electric power.

5.3SWITCHOVER TO PROPANE OPERATION

Switchover from natural gas to propane is made manually, as follows:

1.Turn the fuel selector switch located on the main control panel from natural gas to propane.

The boiler will go through a complete shutdown and restart procedure when the fuel source is changed.

If the changeover is controlled by a remote signal, the switch on the auxiliary control panel should be set at "Automatic" for both natural gas and propane opera- tion; operation of the remote switch will change the fuel source.

During natural gas service interruptions or restrictions, sufficient natural gas is usually available to operate the pilot. In the event of complete failure of the natu- ral gas supply, contact Patterson-Kelley at (570) 421- 7500 for assistance.

5.2.3 Emergency Shut-Down

Natural gas, propane, and pilot gas shutoff valves on the boiler must be closed immediately if an emergency situation occurs.

If overheating occurs or the gas supply fails to shut off at the boiler, to reduce the possibility of an electrical arc, do not turn off or disconnect any electrical sup- ply. Instead, shut off the gas supplies remote from the boiler.

General Warning

Warning! In the event of low pressure in either the natural gas or propane supply the higher pressure gas could backfeed into the lower pressure line. This could result in unsafe operation of other devices connected to the higher pressure supply.

Always shut off the gas cock to a line which exhibits low pressure.
