1. Set the thermostat to the lowest setting.
The integrated control will close the gas valve and extinguish flame. Following a 15 second delay, the induced draft blower will
be de-energized. After a 120, 150, 180 or 210-second delay period (field selectable delay OFF [90, 120, 150, 180] plus 30-
second ramp down), the circulator blower de-energizes.
2. Remove the burner compartment door and move the furnace gas valve manual control to the OFF position.
3. Close the manual gas shutoff valve external to the furnace.
4. Replace the burner compartment door.

This test is to be used for field test mode only, and it will allow gas valve pressure to be checked at 100% firing rate.
1. If both 'FAULT RECALL' and 'LEARN' push buttons are pressed for greater than 1 second, the display will blank to indicate
the push buttons are pressed. Within 5 seconds, both push buttons should be released. If any push button is not released, the
test mode will not activate. The display will return to normal.
2. Once the push buttons are released, the display will flash "Ft" to indicate the push buttons are released and successful
entry into test mode has been achieved.
3. The control will force a high capacity demand. If a low capacity demand is already being serviced, it will be forced to high
capacity.
4. The display will continue to flash "Ft" until high capacity (100%) is achieved. Once achieved, the display will show "Ft"
without flashing. A 5-minute timer will be started to allow sufficient opportunity for the gas pressure to be tested.
5. If a call for heat is given or removed during the test, the system will still operate until the 5 minute test time is complete.
6. During test mode, if both push buttons are pressed for greater than 1 second, the display will blank to indicate push
buttons are pressed. If both push buttons are released within 5 seconds, the test mode will terminate and the system will
return to normal operation. Otherwise, the test mode will con-
tinue uninterrupted.
7. After completion of the 5-minute timer or test mode termi-
nation, whichever is earlier, the system will return to normal
operation, either continuing an existing heat demand or going
to the idle state.
The line pressure supplied to the gas valve must be within the range
specified below. The supply pressure can be measured at the gas
valve inlet pressure tap or at a hose fitting installed in the gas piping drip leg. The supply pressure must be measured with the burners
operating. To measure the gas supply pressure, use the following procedure.
