I have a Rinnai V53DEP propane external tankless water heater. The manual calls for a disconnect, so I provided one.
My plan is (was?) to have a flexible whip take all the wires (power and remote control) into the unit. However the problem is this goofy plastic hinged grommet doodad thingabob under the unit that has threads that don't quite seem to match 1" PVC.
So now I have to come up with some kind of contraption to adapt the goofy plastic thing to the whip. I've gotten this far:
Any ideas? This feels kludgy and flimsy. Oh yeah, and the valve handles are right next to the conduit. I have a set of knockout presses, and I am very tempted to use them
(editorial rant) Arrrrrrrrghhh ... why can't these jokers just provide a 1/2" knockout? Wouldn't that be easier? Why anyone would DELIBERATELY complicate the design of something? Am I missing something? Or maybe I got some weird offshore model that uses North Korean fittings?
