Question about Heating & Cooling
Propane gas is flowing but, the heater won't ignite.
Larry, based on the description you have a bad heat limit switch or bad thermocouple. If you want to repair yourself, I can email a document that will assist you in troubleshooting the issue. emial me at email@example.com.

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.

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.

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... www.desatech.com Thank you

you have to hold for 30 secs to minute once flame is lit if it is like more gas ignition systems
