Okay, so the first thing you want to do is TURN OFF THE EMERGENCY BREAK, so you are sure that the system won't kick in. Personally, I turn off the thermostat, also..

The first thing is to check the pilot flame. If it's white inside, it means that it's not clean, and you are wasting gas because the flame is not the hotest.

If you look at the bottom of the flame, there is a small hole. Just take a straw, and blow air into it. Of course it's going to blow off the flame. This is when you take a match and turn the pilot on again.

If it takes you too long, TURN PILOT THE GAS SWITCH TO OFF, WAIT A COUPLE OF MINUTES, THEN FOLLOW THE CONSTRUCTOR STEPS IN ORDER TO TURN ON THE PILOT AGAIN. BE SURE OF WHAT YOU ARE DOING OR YOU COULD BLOW OUT YOURSELF AND YOUR HOUSE ! I AM IN ANY CASE NOT RESPONSIBLE !

Ok, so now you are supposed to have a nice blue flame like this

Once this is done, you can start to remove the burners

by putting your hand underneath it, pulling toward you,

Lifting the opposite end of it only

pushing everything forward, so the end which is in your hand gets disconnected

and finally removing the burner. I -THINK- the position matter. So remember which one goes to the left, in the middle, and to the right.

Of course do not use anyk kind of permanent marker that could burn. I kept mine in order and did not have to write or mark them whatsoever..

So now if you look inside of it, using a flashlight, you'll see all the dust.

This is when you have to go to the gas station and pay 75c or get a $10 compressed air bottle. I heard that you could also wash them in water. I don't know what would be the result, but if you do so, WAIT UNTIL IT IS TOTALLY DRY before you put it back.

The safest way is to blow air inside I think. So you would put the blower on the top of it, trying to get the dust out through the hole that you can see in the picture above.

Once this is done, just replace the burners, be sure they are locked, be sure that the pilot is ON once again, and if you turn the emergency switch to the ON position, then if you turn on the thermostat, you should see a little switch on the furnace itself, where you removed the door from. If you push it, you should have the gas going in between the burners, and they should light right away (the 3 of them within 2 seconds). If they don't, then you have something called delayed ignition, and this is what create explosions. If you are my friend, call me and I'll come and check it out. If I don't know you, call your gas company !
