Our "sparker" will not turn off

First locate where to light pilot. You can do this by following thin aluminum colored tubing from control valve to inside heater.In general on top of your gas control valve is a knob. Turn indicator of this knob to pilot and depress knob. This will start gas flow to pilot at end of thin tube. Hold this knob in the depressed position and light pilot. DO NOT release knob for 30 -45 seconds. Then release knob and pilot will remain lit. Then turn knob to on position. If pilot will not stay lit you may need a new thermo coupler, which senses heat from flame to keep pilot gas flow open.
Good luck

Hi, follow what I say and it is very easy. The knob that says off, on, and pilot, is where you need to start. You don't want to turn it off now, as its been off for awhile now. Turn the knob slowly pushing down on it until you fill it go down. The knob will go down believe me. When this happens, keep holding it down as this is what starts the gas to the pilot which is back under the burner, under it. Just take a flash light and you can follow the aluminum tubing back and where it stops is where you light it with something long with a match in it or a small rolled up paper. Keep the knob down the whole time you are lighting it. When it lights, keep the knob pushed down for about another minute. Then slowly release the knob and the pilot should stay on. Once you have it on, turn the knob to on, not off. If you turn it the wrong way, it will go off and you will need to start over again. Once it stays on by itself, turn your thermostat up for heat and the burner will light and come on. Just remember that the pilot where you light it is where the tubing goes back under it, as the pilot gas goes through it. You will need a light. Look at the knob with a good light and it will tell you which way to turn it. In the pilot position, the knob will press down to let the pilot gas in, and you can reach back and light it. Then turn knob on. Pilot should stay light. Turn on thermostat and it will fire up. Let me know how it goes. You may have to try a couple of times.

Remember if you smell gas, turn unit manual gas valve off and open a near by window, wait until smell is gone then proceed with these directions,turn manual gas valve back on, turn thermostat down.1.) turn combination gas valve knob to the pilot position and press down knob, if unit has a striker button, push striker while holding down knob until pilot lights, keep knob held down in the pilot position for 20 seconds then let up on knob and turn to the on position, turn thermostat up, main burners should light.

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.

I can try and help. Get a working flash light. If you know where the gas valve is, good I will take you from there. On the gas valve you will find a 1/4" diameter aluminum tube and a 1/16" diameter copper wire both screwed into the valve. Follow the larger of the two tubes toward the heat chamber. The tube will enter inside the chamber and you may have to unscrew a cover to get to the pilot. The tube goes to the pilot assembly. If you have button that snaps when you push it in, that is the pilot starter. Look thru a small viewing port and snap the button. You should see a blue spark. This is where your pilot assembly is.If there is no spark, your sparker is broke. You will have to use a ling match or gas grill starter to light the pilot. OK so if you have good spark, turn the gas valve knob to Off. Now turn it to Pilot and depress the knob into the gas valve. It should go in about 1/2". As you hold the knob in, snap the sparker button a few times and continue to hold the knob in. Look in the little window for a flame. Continue to hold in the knob for about 30 seconds after the flame lights. Now let the knob out and check that the flame is still lit. If it is, turn the knob to the On position. You should be OK from there. If you had to use a match, prior to putting the knob to the on position, replace any screws or plates you had to remove to get to the pilot. Good luck!

instruction on a metal plate inside the fp bottom door
the knob will have pilot/ on/off marked on it on gas valve, you have to line the pilot word up with the white mark on valve then knob can press all the way in, now press it in hit the res or black sparker button and you should get pilot falme in a few tries, once you see flame keep the button in on valve for 30 secs then release turn it to ON and turn youe switch on

Sounds like you have checked most things. A pilot will go out if it is dirty, if the gas valve is not holding or if the senser is dirty or bad. Remove the pilot and clean out the small orifice inside. Check all electrical connections, clean the sensor, and make sure the gas valve holds 24 volts on the PV side.

Most of these have a switch behind each knob that triggers the spark.

OFTEN during cleaning, mositure gets into the switch causing the problem.

If you suspect this, try using a hair drier to dry out behind the knob if you can;t remove and investigate if this could be the cause.

make sure knob on gas valve(inside heater)is turned to on position.3/4" should be fine as long as heater is not larger than than 175,000 btu
