FAULT FINDING Continued.....

Burner Fails To Establish Main Flame.

 Check:

The gas valves are operating correctly.

The combustion air is set correctly.

There is sufficient gas.

The control box is not faulty.

Incorrect Rotation Of Burner Motor

Motor rotates clockwise viewed from the shaft end. If the burner motor rotation is incorrect, the single

phase motor should be renewed. On three phase motors, interchange any two phases. In normal

circumstances, this will correct the rotation.
