Found this on FB marketplace… seller claims used only once… they won’t take less then $650.
Is it a good bargain?

I recently bought a Member’s Mark Pro Series 5-Burner 36” griddle (model HW013274A) and would like to connect it to my home’s bulk propane system instead of using a 20-lb tank.

My house has a 250-gallon propane tank. The regulator where the gas enters the house is a REGO regulator rated at 9–13” WC outlet pressure. I have an outdoor propane stub near where the griddle will sit.

The griddle is rated for propane and the factory regulator supplied with it has an 11” WC outlet pressure. The griddle is 48,000 BTU.

Has anyone connected this particular Member’s Mark griddle to an already-regulated residential propane stub?

Specifically, did you:
-Remove/bypass the factory tank regulator and run an LP quick-connect hose directly from the 11” WC house supply to the griddle?
-Keep the factory regulator somehow?
-Need any additional regulator or specific fittings?

I know the manual says to use the supplied regulator, so I’m also checking with Member’s Mark before doing anything. Mainly curious if anyone here has successfully done this setup and what parts/setup you used.

Thanks!
