Not really. For a desired BTU, you need a specific supply rate and that is
porportional to the length of the supply run and the size of the pipe. Our
pool heater gas line was installed incorrectly by the previous owners. It's
a 250,000 BTU heater and the length of the run to it is about 50 feet, but
it's 3/4 " pipe and can only supply enough natural gas to burn 160,000 BTU.
We had to get a new gas meter and line put in to supply the required amount.
