Read your owners manual to see what inlet pressure is required. You need to also check the diameter of the line to see if it can meet the demand of the generator. There are plenty of discussions on this board that will answer your questions.

If the regulator on your tank is a two stage and reduces the pressure from tank pressure to 11-13 inches of water and the generator is more than 100' from the regulator I think the generator is going to starve for fuel under load. Some of the other experts on this board can help with the technical explanation. With that long pipe run you would be better off tapping off the high pressure side of the tank and installing a high pressure regulator and then installing a low pressure regulator as close as possible to the generator. I hope someone who is more technical will jump in and see if they can correct me and provide good numbers for piping and regulators.

A simple sketch with dimensions and regulator locations would be helpful. You are doing the best thing by getting the manufacturer and the propane supplier involved.

Would a 150 gal LPG tank installed near the generator be accessible for the delivery truck? It would be expensive but you would save laying 250' of pipe.

I do not think I have ever heard of piping liquid propane to a house. Your tank is where the liquid turns to vapor so the devices can burn/consume it. I do not think the regulators normally available work to regulate gas in vapor form.

Correction: last sentence should read ".....gas in liquid form."

 

[oldcodger]

Never seen or heard of such a system. I would like to hear from an LPG installer in your area who would install such a system

OK learn something new each day, but would this be used in a small residential installation?

All propane generators I have seen require 11-13 inches of water pressure and feed the demand regulator on the generator. I have never seen one that required tank pressure.
