Check the entire fuel like to the tank. They tend to break, plug up, etc. which causes a lot of problems. The strainer in the bottom also plugs up. Rick

The fuel is drawn from the tank by vacuum. If there is any kind of dirt in the fuel or tank, it will clog up that tube and not fire up. Also there is a foam filter at the rear that could be dirty. There is also a reset button by the filter that needs to be reset every time it runs out of fuel.

If you brought the heater to my shop with the great (no lie!) description of the problem we would immediately grab a flashlight, shine into the tank and look for water droplets rolling on the bottom of the than. (Keep in mind that a layer of water can be on bottom & not show up with the light)

The next thing would be to use soapy water and try to find a crack in or around the plastic cover and move all the way to the nozzle looking for an air leak. 3.4 at the gauge doesn't mean the air is going all the way to the nozzle.

Next, remove the top cover. Does the heater run fine once removed? If so, replace the worn out nozzle. That heater has some age on it and DESA recommended annual replacement.

The filter is more of a strainer than a filter. It is hollow.

There is a sensor inside that tells the heater that the flame is lit...if it doesn't "see" the flame it will shut down...this may be caused by the filter in the rear being clogged and it is not allowing the pump to produce enough pressure to ensure a good flame or the pump inside may have sucked up some debris and is now not producing the proper pressure required. Another possibility is that there may be enough dust on the sensor itself to cause it to not "see" the flame...if you take the cover off you can find this sensor...it will have 2 wires coming off of it and it looks like a photocell...it should be located just in front of the jet where the fuel comes out...a word of caution...the ignitor(and the spark plug looking thing) have very high voltage on them(around 5000Volts) so I would avoid touching these parts while in operation.
