For what ever reasons our fire did not come on . It has been working ok but as weather has been good have not used it on gas since last May. So removed mico window and blew air to dislodge any thing which could be there. Still would not ignite, have good spark, gas in all other appliances and so far cannot tell whether gas is coming into the fire. My local guy cannot fit me in till next May (he is that busy)) . So presume it could be burner problem but at moment pondering how to get to it without taking fire out. Please do not mention safety as in a previous life I was registered with Corgy. Would appreciate any help, thank you.
