Tankless Water heater distance from propane tank

[George Schnellman]

I can't seem to find a requirement for a minimum distance between a propane tankless water hater and the propane source. ANSI Z21.10.3 gives distances from windows, vents, etc. No mention of hte tank.

ANy thoughts?

Ten feet would be the minimum.

If the cost of propane gas in SC is the as high as it is in NC you client is going to be shocked as to how much the heater will cost to operate. It runs about $5/hr in NC.
