I respectfully believe these two steps are unnecessary: > Set thermostat to Minimum (not miximum as manual dictates).

The mini-poof you mention is from allowing the combustion chamber to fill with too much gas before you spark the igniter...thus when you do spark it, you get a little explosion ... the flame does not liught and you now need to get all those combustion gases out of there before anything will light/burn. > > Push in the air pump about 15 times (without going all the way in to > "click" the spark) > > Hold in the botton that actually lets the gas in and PUMP THE AIR CONTROL 5 > MORE TIMES KEEPING THE GAS BUTTON PUSHED IN THEN PUSH THE ACTUATOR (SPARK) > IN UNTIL THE FLAME LIGHTS. A maximum of 20 seconds). > I NEVER use my pump....haven't used it in 5 years. It's ok to use it, but not necessarily in the way described above. The sparker (whatever) should be pushed in five times (five sparks) or so AT THE SAME TIME that you push in the gas button...not after a delay. It's just like a cigarette lighter...push in the button and propane starts to come out.... that's when you spark it to ignite the flame.. If you delay, you fill the combustion chamber up with propane ... driving out O2 and flooding the system so all you get is a "poof" explosion. After the "poof," the combustion chamber fills with exhaust gasses without enough O2 for any subsequent combustion. At this point, pump 100 times or so, use compressed air or drive around to clear out the exhaust gasses in combustion chamber. If my fridge does not start in the first five sparks right after pushing in the button, or if i hold it in too long by accident before sparking and get the "poof," i know it is not going to start then and there without extraordinay efforts. So, instead of wasting time, I then either turn it on AC seting for an hour or so (convection air currents clear out the chamber) or drive with it on DC for a little bit, and then try. I have never had it NOT start after doing either of these) steve
