Why does my unit make noises?
This can be a result of a blockage in the flue, incorrect vent sizing, incorrect vent length, and/or incorrect gas pressure/gas type. If all of these match the requirements in the installation manual and there is still a rumbling sound, please call Technical Service at 866-766-7489.
