propane regulator
« on: February 03, 2013, 09:06:43 PM »
i am wanting to change out my propane tank connector to the new style and also wanting to put in a new regulator. i found 1 at my local tractor supply but i wanted to make sure this one would work. here are the specs for it.


Brand: Mr. Heater
Type: Non-Adjustable Low Pressure Regulator
Inlet Size: 1/4 in. FPT
Outlet Size: 3/8 in. FPT
Minimum Outlet Pressure: 1/2 PSI
Maximum Outlet Pressure: 1/2 PSI
Outlet Pressure (WC): 11 in. WC to 13 in. WC
BTU/Hr.: 200,000 BTU/Hr.


i know that i need 11in WC but this one goes up to 13in WC. just wondering if that would make a difference. its $19 at my local store..

I'd use a 2 stage RV type regulator.

I replace the POL fitting with an ACME and kept my horizontal (vent pointed down) 2 stage regulator. I have read that you should use a pigtail between the cylinder and the regulator, attaching the regulator securely to something (too much stress on the ACME connector).

An 11"wc regulator is wide open at 9" and closes at 14".

If it were me, I would go to an RV dealer and get the proper RV regulator like this one.

Agreed.  I would really stick with an RV purpose-built 2-stage regulator even though the one you found may work just fine.

It would appear that Marshall is no longer making RV regulators, which is what most of the regulators I've seen in service.  Check out PPL's page on regulators for options.  Cavagna looks like who is picking up the slack.  I've never had any experience nor heard of them before.

I changed out my standard two-stage regulator for an automatic change-over version and love it.  Others will say say stick with a manual set up.  Just make sure you get the appropriate type for RV use, and use the double density gas thread sealing tape (typically in a yellow case) for any connections.

the one on the pup is a single stage regulator, i assume its factory. there is no pigtail just the nut that goes to the propane tank. then the soft hose that runs to the hard line.

 Our 2000 came with a single stage regulator from the factory. I think the 2002 model year on up pups are required to be fitted with a 2 stage.

One single stage? or 2 single stage (1 high and one low)?

     A single stage high and a single stage low.     
                 

The newer models use a single stage high and a 2 stage low.

Why 2 stage?

"With a single-stage regulation, the regulator functions under extreme variations of inset pressure caused by changes in the outside temperature. As a result of these variations in inlet pressure, minor variation in outlet pressure are possible. Two-stage regulation results in a consistent inlet pressure to the second-stage, thereby minimizing minor outlet pressure variations from the second-stage regulator.

Additionally, moisture caused by water in the LP gas or condensation can result in ice forming at the orifice. This can  result in a gas stoppage. The possibility of freeze up is greatly reduced with two-stage LP gas regulation."


As time progresses the 'code' changes and RV makers follow the newest code, from single to separate two stage to a one piece 'RV' 2 stage regulator.

The vent points down.
