Extension Cable and Torch Cable are connected to wrong
sides of RJB. Disconnect air supply and cables and reverse
RJB mounting.
Place Power Supply in Gas Test Mode, verify 24VDC is sup-
plied at gas solenoid in RJB.
If 24VDC (polarity not required) is present, verify pins are
properly installed in 12-pin plug, verify plug is mated com-
pletely until tabs are engaged and/or replace solenoid.
If 24VDC is not present, verify wiring connections made in
Installation step A.2.
