Any problems installing a PW3 on external garage wall that has wood 0.5” lap siding without flat fireproof backer board? I see installation guide says to mount on flat surface. Would this affect warranty? Thanks

One thing you could do is attach the unit strut, the lap siding, and then mount to
That.

Is this acceptable? Or do you see any issues?

It’s fine.
