assembly to fitting on gas/current sensing control. The
gas flow
must be accurately controlled by a
regulator/flowmeter at the source.
E. Touch Sensor Connections
Connect cord with two friction connectors coming from
gas/current sensing
control to touch sensor leads com-
ing from outlet cable. Polarity is not important for this
connection.
