Assembly Instructions For Quadrafire Pellet Stove Test Box Kit, 812-3660 (SO)

To use the Test Box, disconnect the power and remove the Control Box. Insert the Test Box in place of the Control Box and reconnect power. This will allow you to independently test all the systems of the stove.


The Test Box is equipped with two test lights and four switches. A push button on the front upper left side of the box will test the two AA batteries located inside the Test Box. When you press the button, both lights should come on. This light is also the T-stat Test Light. On the top of the Test Box is a seven-amp fuse.

NOTE: When performing tests on the Castile Insert, an adapter must be connected to the Test Box (refer to the Castile Insert service manual).
