Propane Appliances and 20# tanks

[Yonderosa]

For convenience and portability I'd like to use 20# propane tanks to supply a gas range at my mini-cabin.

The range I plan to buy is the Estate 20" Freestanding Gas Range http://www.estateappliances.com/shopping/Specs.asp?Model=TGP200VDQ&Appliance=10200&BaseModel=TGP200VDQ&SpecModelNo=TGP200VDQ

My plan, subject to better advice is to run a flexible pipe from the appliance to the wall where it will connect to hard pipe with a shutoff valve where it will exit the cabin and then be connected to the tank with a rubber supply line. 

Does this sound plausible and safe?

Do I need a pressure regulator?

Many thanks in advance!

First, any coses or inspections to be concerned with. If so, that will guide your installation.

You absolutely need a pressure regulator between the tank and the appliance. If you use a single tank the regulator could be mounted direct as in a gas grill. the flexible line should connect to black iron pipe. The black iron pipe takes the gas from there into the cabin. Inside there must be a gas approved shut off valve on the iron pipe stub. From there a flexible metal gas line would connect to the range.

While you're at it consider installing a tee and stub you can use if you ever want to add something.

Now, with that said I'd advise you to consider 40# tanks at a minimum. Much less hauling to and from the refill station. Also, if allowed or if not in a code zone consider using an automatic transfer regulator. They are common in the RV trade. That will allow uninterrupted service. When tank #1 is empty the regulator switches over to #2. You can refill #1 and then bring it back. I have four tanks I rotate to save on the number of trips to the refiller.
Here's a link to an RV dealer I've been happy with for years.

Not a very good picture...

MANY Thanks Don!  Exactly the insights I was looking for.

Just curious - does this require type of gas range require any electric?  The cost to run electric is still prohibitive and we're looking for cooking options.  This might be a possibility if it doesn't require any electric.  The link didn't connect so I couldn't get to the web page to look at any specs.

 Also make sure your regulator is large enough to handle your appliance! Too small and it will freeze up. BBQ grill regs. are too small for most stoves with ovens.
One other thing to remember is what you will haul the tanks in. It is illegal as well as very dangerous to haul them in an enclosed space (car trunk, Van, SUV) or laying down in the bed of a truck. The blow off valve HAS to be upright and always in the vapor space at the top of the tank.
I do agree with MD about the larger bottles but just as a guide line as to how heavy you will be lifting propane weighs about 4.29 pounds to the gallon not counting the tank and the weights they list are net weight in liquid not the tank too.
The best place for advice will be an actual propane distributor and not Lowes or Home Depot.

Some of the small ranges have no electrical needs at all. Some use electric ignition.

Virtually all gas ranges are set up for natural gas so you must convert them to LP. It is not difficult and the range installation instructions will include directions---no new parts usually required outside of the tank mounted regulator.

That's right on, RW. Ours came with a small bag of propane orifices taped to the back of the range.

Thanks for all of the insights.  VERY helpful.  I ordered the range http://www.sears.com/shc/s/p_10153_12605_02270702000P?mv=rr from the Sears in a nearby town.  With any luck I'll be making scones next month.
