OPERATION
1. Turn the gas control knob counterclockwise from
OFF to the PILOT position.
2. Push the knob down and hold in position. The pilot
valve opens and allows gas to flow to the pilot
burner.
3. Push the plunger on the piezo until the pilot burner
is lit. When the pilot burner is lit, the LED on
the control will come on after approximately
60 seconds and will blink continuously.
4. Release the gas control knob. The shaft moves
upward and the pilot burner stays burning. If the
pilot burner goes out, repeat steps 2 and 3.
5. Turn the gas control knob counterclockwise to the
ON position. If the manual switch is in the LOCAL
position, the main burner will turn on immediately.
On the initial use of a transmitter, a recognition operation
is required between the receiver/valve and the
transmitter.

Shut-Off Procedure
If the manual switch is in the REMOTE position, the
RT8220A transmitter can shut off the main burner and
fan. However, the control is still on and a command from
the transmitter can turn on the main burner and fan.
To shut off the system:
Turn the gas control knob clockwise to the OFF position.
This closes the main gas and safety valves. The
transmitter cannot turn on the main burner or the fan.
