I can help with part of this problem. The thermocouple is a sensor right next to the pilot flame. When heated by the pilot flame, it generates a small voltage. This voltage opens a small valve and feeds gas to the pilot. If the pilot light should go out, the thermocouple stops generating voltage. This causes the gas valve supplying gas to the pilot to shut off. I oversimplied the way it works. If this does not make sense. Google how a thermocouple works.

Have Cozy heater model# CDV251A .Have spark , gas/but it will not light?


Be sure the control knob is set directly on the Pilot position. When you depress the knob, if it doesn't go all the way in (Bottoms out), release the knob and turn it a hair one way or the other, until you reach the point that it will bottom out when you push it in. If that doesn't solve the problem remove the front cover to expose the pilot assembly and blow out the pilot with compressed canned air (like you clean a computer with) and blow out the pilot tip. Any other dust or lint you see, clean that out too. Reassemble the cover and try lighting the pilot again.

in front of the burner it is next to a copper tube(black if it has been burned)! it angles a little towards the copper tube! u turn the knob on gas valve to pilot then hold down and light hold for one minute then turn it to the on position (u might have to push down slightly as u turn the knob) make sure u have thermostat to the lowest setting before u light the pilot so it won't turn on while u have your face too close to the heater then turn your thermostat up to desired temperature when it is on the the on position! Good Luck!!

This sounds like the connection for your thermocouple has lost a good connection.

Need to light pilot cozy brand gas wall heater


Is there a "Pilot" marking on the knob? Try moving the knob 1/2 way between on and off and depress the knob. If you are in the correct location, the knob should depress in about 3/8 of an inch. Once you find the location where you can depress the knob, there should be a red sparker button that you can snap to light the pilot. Depress the pilot knob and snap the button a few times. There may be a small viewing port at the pilot. It may be covered by a small metal shield held on by a thumb screw. You can remove the shield to view the flame. OK so now you can depress the pilot knob, snap the sparker, look for the flame while still holding down the pilot knob and count to 30. Slowly release the pilot knob and check to see if the pilot is still on. Once it stays lit, rotate the knob to the "ON" position.

Open the lower panel. You will see a valve with a knob marked On Pilot and Off. This is the gas valve. Turn the knob to Pilot. Push in on the knob and if you are in the correct setting, the knob will depress about 1/2" into the valve. Now look for a red button and snap it in much like a gas grill starter. Keep the knob depressed and look into the small viewing port to see if you started the pilot. Hold the knob for 30 seconds then let it out. You should see a blue flame. If you don't , try it again and hold the knob in longer this time. Once you get the pilot to lite, rotate the knob to the On position. If for some reason you can't get the pilot to stay on, you may need to replace the thermocouple. If the pilot won't light at all, you may need to get into the pilot Assembly with a long match or grill lighter and light the pilot.

Is there an air filter for my ''Cozy'' Counter Flow Wall Furnace


Cozy most generally doesn't provide a place for a filter in its wall furnaces. I have seen people secure a typical house filter to the outside grill where to return air enters. It's cheesy but works.

On the gas valve, look for a marking that indicates "Pilot". If there is no such marking, you do not have a pilot and the system is electronic ignition. Ok so if you find the pilot position, you will be able to turn a know to that position and depress the knob into the gas valve. At the same time you are depressing the knob, look for a red button that snaps when you depress it. This is a Pizo starter. If you do not have this button, look for a viewing port where you can insert a long match. Once you have the knob depressed and the viewing port open if needed) you should be able to light the pilot with the snapper or match. Before you release the knob on the gas valve, sing "Yankee Doodle". This will give the flame enough time to heat up a probe to the proper temperature and the flame should stay on. Button up any port you opened and then turn the gas valve knob to the "On" position.

On top of the gas valve you will see a knob. Turn the knob to the position that says pilot. It's on the side of valve. Press the knob down with one hand and take your long lighter stick it by the pilot tube looks like a small aluminum tube should light pretty quickly hold for 30 seconds release the button you have been holding down. Now turn the knob to the on position. Make sure the thermostat is turned off so the flame don't fire up as soon as you turn knob. If you are uncomfortable gas your gas company and they should come out for free.
