Verify proper 120VAC power supply to the 6V DC transformer.
•
Verify the control module back-up battery pack and the remote
control batteries are fresh and installed with correct polarity.
•
Verify all connections between the wire harnesses and the
system components are proper and positive.
•
Verify the communication link is established between the remote
control and the Komfort 8K1 control module.

Verify inlet pressure meets the recommended inlet pressure. If
necessary, adjust line pressure regulator.

To isolate remote functionality from the control system when
troubleshooting, turn the ON/OFF/REMOTE selector switch on

Issue
Cause
Solution

with the flame rectification sensor
on the pilot assembly
Verify the pilot flame envelopes the top of the flame sensor and extends
