6-10 during operation. The probable cause in this case is an intermittent failure of an ignition m odule. When the unit is opened up for troubleshooting, th e m odule cools down enough to operate correctly, but when the unit is again closed up and placed back into service, the module heats up and fails. PROBLEMS RELATED TO THE GAS VALVE If the prob[...]

6-11 If popping is consistent during all hours of operati on, the most likely cause is an insufficient air supply. Check for “negative pressure” conditions in the kitchen area. If air is flowing into the kitchen area, this indicates that more air is be ing exhausted than is being replenished, and the burners may be starved for air. If the rethe[...]
