the combustion. The values should be in the range listed in

in the Armor Service Manual for possible causes and
corrective actions.

shutoff device by turning the manual shutoff valve to the
OFF position and ensuring that the appliance shuts down
and registers an alarm. Open the manual shutoff valve and
reset the control.
