Monitor 2400 Heater
I finally got a look inside a Monitor 2400. Mine kept on giving me an E-14 readout. The prepurge came on, I had ignition, but when the heater kicked into high, I got flame out and the heater would shut down and lockout.
I found that the fuel line had a water-ice blockage somewhere in the inlet line. Once this was cleared up the heater would run and run.
The front cover is removed by taking out two screw on the side(s) lower. Then by removing three screw on both sides and one screw right in the middle of the louver assembly comes out.
The combustion pot is the same, the flame rod is the same, the solenoid pump is the same exceot that it plugs directly into the computer board. The air proving switch is the same. The fuel sump is smaller and doesn't have an adjustment for the float. The float is plastic and pivots in a plastic holder. The float looks just like one used in a garden tractor. At one end of the float is a piece of metal. This metal piece contacts a magnet should the fuel level get too high in the sump. It is reset by using a lever attached to a button for the user. The combustion blower is the same I couldn't see the damper but there isn't the omlnous click when the heater clicks into high heat.
