SOURCE: Nexgrill patio heater won't stay lit

I called Nexgrill technical support at 1-800-913-8999. They are sending me a new thermo couple to keep the valve open when ignited - so the patio heater will stay on. I needed to give them the serial number (inside the propane tank door) and fax them a copy of the receipt.

Hope this helps.

Your thermocoupler seems at fault. The thermocoupler is that probe that sits in the pilot flame. It controls the main fuel valve. Make sure that probe is in the pilot flame, better at the tip of the flame and hold the button down for a minute or so after lighting the pilot. If pilot extinguishes, the coupler is faulty. If pilot stays on the heater should fire up when you let up on the pilot button.. Good luck

BE VERY CAREFUL sticking matches in any propane appliance! With the gas OFF see if you can physically see the spark when you push the ignitor, if yes, the problem may be the regulator or bottle pressure the only test i am aware of for the regulator is replacement.

Go to www.grainger.com and look for a "power pile generator" this is a millivolt thermocouple that may be just what you need to make your heater work again

Check the tip over senser,,, it is a plastic senser located under the screen, usually near the knob. It has 2 wires running to it, jumper them together and try it,, then order a new senser from the manufature.
Good Luck

If you're using a 20lb propane tank (Gas Grill Tank), that may be the problem. Turn off the propane tank at the tank valve and disconnect it from the tank. Wait 5 minutes and reattach the heater hose to the tank. Turn the propane tank valve on very,very slowly until it's all the way open. Try lighting your heater now. If the pilot flame height returned to normal, that was the problem.

FYI - The Thermocouple has nothing to do with the length of the pilot flame. It's a safety feature that stops the gas if the pilot flame goes out for any reason.

Hope that solves your problem. Please let me know.

Is there a trick to starting the Pyrox 400? Turned the fan on and press on low then repeatedly press the ignition pilot light, start to smell of gas after a minute. Won't start Help please


Is the ignition sparking? When you press and hold down the buttons, the ignition should be sparking at the centre electrode. At the same time when you hold the buttons down, the gas valve is manually held open to release the gas. The spark is then supposed to ignite the gas. Hold the knobs down for about 3 to 5 seconds after ignition and the gas valve will stay on. If it lights but the flame wont stay on, it could be anything from a partially blocked aeration port to a worn knob. When you push down on the knob, it is supposed to press down on an electromagnetic lock which keeps the gas valve open when the flame is burning. When the knob or shaft isn't pushing down enough, it doesn't keep the gas valve locked and the flame will go out as soon as you let the knob go.

Kozy world propane wall heater pilot will not light


This can be caused by several things:

1. The inline gas valve running to the the heater is OFF. Turn the valve ON.

2. The gas control knob on the heater is not exactly in the PILOT position. Unless the knob bottoms
out and you feel strong pressure (other than spring pressure) pushing back at you. It's not exactly
in the PILOT Position. Once the pilot lights, hold the control knob in for 30 seconds to 60 seconds
to allow the Thermocouple to full heat.

3. The pilot is dirty and needs to be cleaned, as do the burners.*

4. The LP Gas Tank is empty or to low to maintain te proper gas pressure.

* Here is a link to a demonstration on how to properly clean the pilot & burners.

My coleman 5033-700 does not have a ignite button, so how do i light it?


Turn the knob to the light position, light the heater with one of those long bic lighters or a match, turn the knob back to the run position. Takes a little while for the catalytic mat to fully light up.

We have a gas wall heater product number 4690011 and we do not know how to start it;


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.

Napoleon PTH10PSS Infra-Red Patio Heater


If you have a piezo ignition, then all you will hear is one click when you turn the knob. If I am guessing correctly, when you push in the knob and turn it, the gas flows to the pilot assembly, when you turn the knob far enough it will clilck and that sends the spark to the pilot assembly to light the pilot. Try turning the knob slowly before you get to the click, that will allow more gas to flow to the pilot. If this does not work, then you may have a blockage in the pilot.
