I just pulled out my defective but old H20 propane
heater and replacing with a electric/propane model of same dimensions.[SW6DE]. What a bear pulling it out with all the sillycone they put around it and around the frame too. Took a long time to get it out. I hope the new one lasts a long time BUT I am thinking instead of riveting it back in is to use the threaded inserts and Butyl tape in place of the DAP. My logic is the tape will stay soft and some what pliable and the inserts will allow me to use a 6-32 or 10-24 bolt. The current rivet holes are enlarged just a tad from the original and maybe it would not allow the proper spread tension with a new rivet? I took the seat off and attacked it from the backside otherwise I would still be out there. Casita
used rivets into the sides of the frame insert to hold to the main body. [not knocking their construction techniques but added additional time to get those freed up].
Any rate has anyone used the B tape for that purpose? I do have the DAP 600% expansion sealer I could use and go back to the original installation style. Just hope this one lasts 17 years too.
