Just opened the pool yesterday. Filled it up last night, ran it through the main drain all night after adding salt and switched it to the skimmer this morning. This will be the heater's third season. Anyhow, it went through it's normal cycling, with the clicking etc. Faint smell of gas. I got the usual 'woomph' when it lit and then it went out 2-3 seconds later. After three times I got the IF code. The first two seasons, it lit first time, every time. Any ideas this time?
Does the 'woomph' mean gas is getting to the heater?
