I bought a 200,000 BTU pool heater, to be installed outdoors.
The model is Hayward H200FDN.
The size of the pip ``Based up ``Hayward will not be responsible for heaters that soot up due to improper .. natural gas line sizing''.
If I cannot provide this heater with adequate gas flow, I can upgrade most of the piping from 3/4" NPT to 1" NPT, it is roughly a day or work and some money.
To question is, do I need to do it?
So, I thought, I could turn to measurement of the gas pressure right at the inlet of the pool heater. If the gas pressure at the inlet, when the heater is running, is above the recommended value, then I am fine.
I do have a pressure gauge that I could use.
My question is, and here's where I am not sure, what is that "recommended inlet pressure". Is that 0.5 PSIG when the heater is running? Am I reading that right?
thanks
