TROUBLESHOOTING GUIDE
(continued)
CAUTION:
DURING TROUBLESHOOTING
PROCEDURES MAKE SURE A SPARE
SAFETY PULL PIN IS INSTALLED IN THE
EXTINGUISHER HANDLE. THE SPARE
SAFETY PULL PIN MUST BE REMOVED
FROM THE HANDLE WHEN
TROUBLESHOOTING IS COMPLETE.
•
If there is still NO gas flow to the stove, verify that
the gas valve is properly plugged into the Gas
Shut Off Assembly control box and the
connection is fully mated. (The gas valve is
normally closed and is energized when power is
supplied to it.)
•
If there is still NO gas flow, unplug the gas valve
and measure for 24 VAC voltage between the
black and white wires. If there is voltage
measured at the connector, replace the gas
valve.
NOTE:
After performing the above steps and there is
24VAC at plug and if the gas flow indicator light is not
lit indicating gas flow, check the bulb indicator light. It
may need to be replaced.
•
If there is NO voltage at the connector that plugs
into the valve, replace the Gas Shutoff Control
box.
•
If voltage exists at the connector but gas is still
not flowing to the stove when connected, then
replace the gas valve.
Problem:
No Shutoff Activation using the
Interconnect Cable
•
Confirm that power is supplied at the wall outlet.
If no power at the wall outlet exist, check the site
condition.
•
Press the “Reset” button on the main CPU and
make sure that the green indicator momentarily
illuminates. If green indicator does not illuminate
then run “Diagnostic Test” on pages 5-6 of this
manual.
•
Plug the Gas Shutoff control box into the wall
outlet and momentarily press the “
Power Reset”
push button. When the switch is pushed it should
supply power to the stove and will enable the
“Valve Reset”
switch on the Gas Shutoff Control
Box. (The “Power Reset” must be pressed before
the “Valve Reset” Switch will work. This is a
safety feature.)
•
Momentarily press the
“Valve Reset”
switch to
open the gas valve to the stove. The gas flow
indicator light will illuminate
•
Verify that the Interconnect cable between the
Main CPU control board and the Gas Shutoff
Control box is plugged into to the correct
connector on both ends of the cable and that the
connectors are fully mated.
•
Perform “Arming the System” procedures on
Page 15. If power/gas to the stove stays on after
a diagnostic test and there are no Diagnostic
Code “beeps” then perform the next step below.
•
Disconnect the interconnect cable from the Gas
Shutoff Control box. Using a small piece of wire,
create a short across the two outside pins of the
white 4 pin socket on the shut-off.
Note- Do not
make contact with either of the two inner
pins
. Activation of the shut-off should occur. If
activation does NOT occur, replace the shutoff.
•
If activation occurs, reset the shutoff, reconnect
the interconnect cable and perform
Arming the
System
on page 15 again.
If power/gas to the
stove stays on after a diagnostic test, and there
are no Diagnostic Code “beeps” then replace the
Main CPU board.
Problem:
No Shutoff Activation using the
Wireless Transmitter/ Receiver
Assembly
•
Check that Wireless Receiver is plugged properly
into the shutoff and that the Wireless Transmitter
is plugged properly into the main CPU.
•
Make sure that the Wireless Tx/Rx are not
installed inside metal cabinets or enclosures that
can impede the wireless signal.
•
Make sure the shutoff is reset and the stove has
power, check that the main CPU has power from
a good 9V battery.
•
Perform “Arming the System” procedures on
Page 15. If power/gas to the stove stays on after
a diagnostic test and there are no Diagnostic
Code “beeps” then perform the next step below.
•
Disconnect the interconnect cable from the Gas
Shutoff Control box. Using a small piece of wire,
create a short across the two outside pins of the
white 4 pin socket on the shut-off.
Note- Do not
make contact with either of the two inner
pins
. Activation of the shut-off should occur. If
activation does NOT occur, replace the shutoff.
