We just installed a BIS 1.0 fireplace and are loving the heat.
Both fans run well, but they are remarkably noisy. I looked at replacements but the parts guy said they wouldn’t be any quieter.
Has anyone tried to retrofit a squirrel cage fan in a unit like this? Or any suggestions for making the fans less noisy?
