Just want to run this by you to get good information. I've got a very small cabin for weekends. I want to install a couple of small propane radiant heaters and this tankless water heater. At least initially I'll be running them off of a 100# propane tank with plans to eventually converting to a 250 gallon propane tank. My question is about what is acceptable for the gas lines. The water heater will be about 10 ft from the small propane tank which is outdoors. The water heater will be mounted in the garage and vented outside about 6 ft above the enclosure (vented) where the tank is to be located.
The tankless WH comes with a 3/4 gas line connection. My intention was to run 1/2 soft copper from the regulator to all the appliances with appropriate shut off valves. This is the type of set up and plumbing I've seen "normally" on propane systems. What's making me question this is the 3/4" connection. I don't get involved in gas or propane plumbing very often so don't know the rules or code for what type or size piping is allowed by code. My #1 concern is always SAFETY, especially with gas.
