How far is the heater from the meter. When I installed mine, I had to purge air from the new line to get the heater to fire. My line is corrugated stainless, 1" diameter, 115' long at 2psi. Opening the purge port on the heater valve, it took somewhere between 15 and 30 seconds before I smelled gas. Closed purge port, waited a few minutes for any residual gas to go away, then it lit almost immediately.
