Electrical propane shut off valve

Hi I recently added a propane heater on my boat and, as per code, I need to install a second low pressure regulator for propane. I am also installing a second shut off valve and I was wonering if i can run it off the same switch/breaker as the existing one that controls my stove. Or maybe I need to use a different breaker all together!

Using the same one would be easier installation. I was thinking of setting it up in parallel. Any thoughts?

Thank you

Re: Electrical propane shut off valve

I am a bit confused here. You have two separate propane lockers? I was under the impression one solenoid valve per locker and then the regulator and then the leak gauge and then a "T" for two lines all of which needs to be made inside the locker. I am no expert but I believe this is true. Greg

Re: Electrical propane shut off valve

1 if it is a Trident the breaker will trip if you ask it to supply two solenoids.

2 IMHO you need 2 seperate systems as you are likely to be running the heater at different times to the cooker.

Excuse my lack of knowledge but is trident a type of breaker or the way it is wired. And I think I will be running 2 seperate systems. Thank you for your HO!!

Re: Electrical propane shut off valve

You can go from the tanks to a T with the output going next through the regulator. From the reg another T and a solenoid on each line.

I have not seen a dual solenoid installation on any boat.
Most installations I have seen use one solenoid and regulator with a T to the appliances similar to that shown below.

Re: Electrical propane shut off valve

The Trident control panels use a solid state relay to control the solenoid valve. The panel's relay is rated for 1 amp-12vdc and that is what the valve that they sell draws. Two valves gives an 100% overload. I am in agreement with several others-- you only need one valve. the valve (on the high pressure side) will pass all your stove and heater together can use. The regulator is rated for something like 100000 btu/hr and your heater is probably about 10000 but / hr. The stove with oven might be 50000 but /hr.

Re: Electrical propane shut off valve

A Force 10 stove (3 burner) has two 5,000 btu and one 8,000 btu burners. The oven has a 5,000 btu burner. With all on that is 23,000 btu. It would be a pretty large stove to be anywhere near 50,000 btu.

Just wanted to mention that the code now, for a two tank installation, is to have a regulator with two gauges, and two hose connections, so that each tank can be individually leak checked. I have a PR-5412 (scroll down).

All your comments about the second T arrangement I agree with though.

I also have the S1-A leak detector and solenoid valve control.

Which code requires a 2 gauge regulator?
