    My Cozy Challenger floor furnace has a good pilot and thermostat but it won't ignite unless I tap the valve, then it starts fine.

SOURCE: Pool Heater

You can light the pilot with a B.B.Q. lighter.

Nottoohandy. Backwash you filter, make sure it's really clean. If that doesn't work it could be the pressure switch. You can by-pass the switch with a piece of wire to see if it fires up. If it does, it's the switch. There is a picture of the switch in the manual.

SOURCE: warm morning propane heater. new thermal couple.

There are basically three things that can go wrong with the Warm Morning .
Sensor shut off. There is a sensor button on the back of the unit with a wire going from it to the thermocouple. This sensor turns the heater off if the flue is blocked, however it will also shut the heater off if the wire contacts are dirty, or if the sensor has gone bad.
You can test this by bypassing the sensor. Disconnect the two wires from the sensor and reconnect them directly together. If the pilot stays on, your problem is here. Try cleaning the wire contacts first.
Pilot orifice. If the pilot flame is small and doesnt look healthy, the pilot orifice may need cleaning. The hole is very small and can get dirty. Disconnect the silver tube and clean with electrical parts cleaner. Never try to clean the hole with an object like a pin, you may damage it. You may have to slide out the burner unit to get at the silver tube. (Always shut off gas before disconnecting lines and after you reassemble, spray joints with soapywater and look for small bubbles which may indicate a gas leak. Dont use parts cleaner around an open flame.)

Thermocouple can go bad but this is not as common as the first two problems.

SOURCE: 150,000 BTU propane Reddy Heater shuts off after ignition

Is there a frost line on your LP tank, if so you may need to replace the tank with a larger tank or refill your tank. This can happen if the tank your using is too low or too small (use 100 lb tank or greater). If there is no frost line it may be an issue with the thermocouple. The manufacturer offers a service manual and owner's manuals on there site. This should assist you... Thank you

Boiler won't ignite for hot water unless heating is on.

If this is in a RV the propane monitoring valve may require more gas flow to turn on than the water heater requires. A central heating system requires substantial gas flow so when the monitoring valve opens to fire the central heating, there is enough gas flow to also fire the water heater.

Napoleon Fireplace propane Pilot won't light main burner even though gas flows in?

  • I'm going to assume your fireplace has a pilot light.
  • Follow the little holes in the burner that lead to the pilot light.
  • Make sure the pilot flame is pointing directly at the closest burner hole. (adjust if necessary).
  • Often, you will need to sprinkle a layer of "glowing embers" in this area. The embers will help the gas travel to the pilot light and ignite.
  • Always start your propane appliance on "High" never "Low". Cold propane likes to drop to the bottom of the firebox and accumulate until it reaches the pilot (this is called delayed ignition). Keeping it on "high" will help the fuel travel over to the pilot without buildup.

Portable patio heater is a DCS Phoenix Professional Patio Heater Model PHF8-DWBZ-L. Burner ignites and operates for a few minutes. Then teh flame is reduced to a short yellow flame. Regulator is covered...

The regulator covered with frost is the problem. It freezes the gas and the gas line up. But, usually this only occurs when it has been exposed to subfreezing (in the teens) temperature for a long period of time. The quick fix, is to soak a bath towel in hot water, ring it out and quickly wrap it around the regulator. Once it thaws, the gas will start flowing again and you can light the burner. Generally, once it's flowing and being used, it won't freeze up again, right a way. Most propane companies add ethanol to the propane in the winter, to help keep it from freezing in the lines and the regulator.

Hope this helped answer you question and provided, at least a quick fix solution.
