Oven stops heating, gets quiet...
The most common problems are prevented by maintenance cleanings. The most often area that is overlooked is the Circulation Fan Motor. This motor is exposed on the back of the oven. If the motor ventilation grill is not regularly cleaned, the heat of the oven WILL cause the motor to enter a state of thermal protection. This problem often shows itself when you least want it to occur, during peak hours. As the oven demand increases, so do the BTU/Hr, causing more heat to travel down the motor shaft and to be delivered directly to the motor. In normal situations, the motors internal fan cools this heat and the motor can function normally. When clogged, the motor will overheat, shutting the entire combustion system down. Please keep your oven operating reliably and clean the motor ventilation grill on a monthly basis.
What type of Manometer should I use to measure gas pressure?
Instrumentation has come a long way. Technology gets smaller, batteries last longer. We now have gauges and digital meters with knobs, buttons and multiple taps... they all pale in comparison to a basic, $30 Dwyer 1213-15 water manometer. We measure gas pressure in Inches of Water Column. This instrument is essentially a column of water. What could be more accurate than that? This is the tool used during EDGE Oven in manufacturing, this is the recommended gas measurement tool of EDGE Ovens, this is the, tool we swear by.
