    FVIR power vented problems

    Has anyone run into problems with the power vented water heaters? the gas valves locking out or sensors failing ?
    We have had serveral that lock out as the sensors are sensitve to humidity and temprature , some of the gas valves wont reset after lock out and must be replaced to get the water heater working ,
    I was wondering about power supply how sensitive are these gas walves to power fluctuations , most of the failures seem to be in 1 corner of town

    the state and bradford white power vented models are bolth having premature failures within the firt months of start up. the gas valves are failing and none of the local wholesalers are carring the right parts for repair , we have 8 water heaters that are still waiting for parts 8 months later there still sitting is our shop because we used parts from them to repair installed water heaters .
    there all missing the same parts.
    State has the intelevenet gas contol from white rogers and B&W has a spark ignition from honeywell

    What are the numbers on those

    controls from Honeywell and White Rodgers? I need that in order to help you out with what may be the problem.

    By the way make sure the polarity is correct on all of those units!!!

    BW uses the honeywell spark control. I understand that the spark control is not polarity sensitive, unlike the hot surface controls with most furnaces

    Reverse Polarity

    is a problem on any control system as when the polarity is reversed then the R and C terminals on the secondary of the transformer are reversed and this can cause problems as burner ground, MV/PV and 24 volt ground are the proving circuit for the flame rectification signal to prove flame.

    all of our installs are checke for polaity it was a problem when the first came out everyone got a tester
    the most commem code on the state is first and last light shown and also the ignighter has failed , its usally the gas valve and not the igniter
