I have Pentair MasterTemp 250 Liquid Propane version recently installed.
Connected to a standard LP bottle with 30ft (10m) hose thru domestic gas regulator (works good for gas cooktops, water heater etc.)
Here is the regulator specs:
When heater starts I can hear some solenoid clicks inside the gas valve and ignition LED is on. It tries to ignite for 3 times and then stops. At each try I can smell a little bit gas and then nothing.
After three unsuccessful attempts to ignite Fenwall diagnostic LED blinks 3 times (ignition lockout). No other diagnostic LED's were lit (AGS, AFS, SFS, HLS, PS...)
Blower works fine. Gas control switch in ON position. No problems with water pressure as it tries to ignite so I think it's gas pressure/flow related.
User guide is not clear about the gas pressure for LP version but later I found this label somewhere inside:
