I have two stand-up type wall heaters that are fairly old. Recently, they have have started to have some flash outs when the thermostat tells them to kick in. By that, I mean that the gas ignition process causes a very temporary and quick flame to expand out past the "enclosed" lighting area.
What could be causing this. I had someone tell me that the recent cold weather could be causing a slight downdraft but thought it might also be something else.
Thanks,
Bill
