Waterproofing tankless water heater install
I am installing a Girard tankless water heater in my tt. The new water heater is 13x13, while the old Atwood 6 gallon had a wider clearance. This will leave several inches open on either side of the new unit that must be closed up prior to water heater installation to prevent water damage. What is the best way to patch this? I have a '16 jayflight slx 28bhsw with aluminum siding. Was considering purchasing a small piece of siding, cutting it to fit, sealing it and fastening to the existing siding and studs framing the water heater. Thoughts? Any method your can think of that will allow me to patch this without a special order of siding? Entire patch will be behind water heater door so aesthetics aren't a concern. Sheet metal with butyl tape?
