using a gas hose on a Empire DV-215 ??

Hi Guys….
A couple questions:

1) I’m installing my new heater soon and I bought a two stage auto-changeover regulator for use out at my new dual 20lb tanks setup. Is this OK? Or does the Empire furnace not need this because it has it’s own internal regulator of some sort?

2) This will be my first season with my new 8′ x 12′ skidhouse and I just want to get the basics done to get it out and see what stuff I want to do more fancy for next season. I’d rather not hard pipe the LP from the furnace over to the exterior tanks about 12′ away. Can I just order a gas hose that long off the Internet and string along the inside shanty wall and then pop out at the spot the tanks are hanging? Do you guys install a “cord hatch” or a “hose hatch”? Will a hose go right from a regulator onto a furnace, or will there need to be nipples installed?
Also, I see there are high pressure and low pressure hoses. I’m assuming the Empire is considered low pressure? If long hoses are only available in high pressure, will that matter to the Empire?

Thanks to anyone that’s been through installing their own Empire and the related layouts and hookups.

I make all my propane hose using automotive vacuum hose, black with nylon web inside.

It is very flexible in cold, you will have to make your hose fittings with hose clamps and hose barbs which yo can find at Fleet Farm or local hardware store.

what type of t’s do u use? how long have u use this line? how long do u think it last? I work on cars all the time, and I know those barbs wear into the hose when you have a clamp on them. I would think that there would be a time line with the hose, also the more fittings the more chance for leaks. I would not be againt using the hose but it would help if I had a time line on it’s life.

A couple follow up questions.

If I use a hose, can I run it into the furnace thru the hole in the bottom and connect right to a pipe nipple added? Or do I need to hard pipe to the outside of that same bottom hole and make the hose connection below the furnace? Are the hoses rated to be inside the lower furnace area?

Keep in mind I haven’t run the furnace yet, so I’m not familiar if the whole area inside gets real hot or only certain areas. It seemed odd to me that in the back lower left corner where you mount the wall screw, that the area has exposed wall showing? Is that right? I mounted mine to a plywood board and it seemed odd if it gets hot in there to see bare wood showing at the back of the furnace?

I’d save the hassle and build it with copper and compression fittings and/or flex line, worked well for my LP garage heater.
