TROUBLESHOOTING ELECTRICAL PROBLEMS

NOTE: When 120 VAC is applied to terminals L1 and L2 of the SS2 terminal strip, the SS2 may start up and run for 1 to 10

minutes. Do not initiate a call for heat with the appliance until the SS2 is finished with it’s post purge time cycle.

The following guide is intended to be used if a problem occurs during
the use of the SS2 side wall vent system. At several steps through-
out the guide you will be required to measure 115 Volts with a volt-
meter, (See Diagram L).

Extreme caution must be exercised to prevent injury. If you are
unable to determine the defective part with the use of this guide, call
your Tjernlund distributor or Tjernlund Products direct at
1-800-255-4208 for further assistance.
