Lime / Scale Build-up
If you receive Error Code “LC”, refer to the procedure, Flushing the Heat Exchanger. Refer to the section on Water Quality to see if your water needs to be treated or conditioned. (When checking maintenance code history, “00” is substituted for “LC”.)
Snow Accumulation
Keep the area around flue terminal free of snow and ice. The appliance will not function properly if the intake air or exhaust is impeded (blocked or partially blocked) by obstructions.
