Weishaupt Commercial Burner

WayneMech Member Posts: 53
I was called to work on a Weishaupt W-FM commercial burner, fit to an 50's vintage steamer. Although I have read the manual (more than once), it makes little sense. No disrespect to our European friends, but it may have to do with Germans writing tech manuals in English. Calls to the rep have not helped, and the customer has placed their faith in me. Does anyone have any experience with these burners?

    I dealt with these. Excellent burners. I agree, manuals are written in german english, as usual.

    The problem is that the pressure setting is too high (4 lbs!), and I cannot seem to adjust it. They are VERY unhappy with the fuel bills, noise, and discomfort.

    Pressure for what? Oil, gas, steam?

    It is full modulation, electronic, set up trough burner controller, you will probably need pressure transducer for steam pressure reading, so burner can modulate. it should come in burner package. Same principle as Q series industrial combustion burner with siemens control. But weishaupt is simpler. For steam pressures below 1 psi you need different transducer, must be specified prior ordering.

    Sorry, Steamhead, I am referring to the steam pressure. Everything else is ok, I just cannot get the steam pressure down.
