Water heater

The water heater in my Gulf Stream won't light. I've checked and cleaned but no gas.
Does the Surburban SW6D use a module. Where would I find it?
  • YES the SW6D uses a module -----'D' stands for Direct Ignition

    The DC wiring Junction box is located on left front corner of WH Tank (Looking at it from backside---inside RV)

    The module will be mounted on wall etc (some where close by) ---comes loose/not attached---RV Mfg. installs it)

    It will have Red, Blue, Brown, Yellow & Orange wires to/from module
    RED......12V DC from switch thru T-stat to Module
    Blue is 'Fault' light...from module to light on switch
    Brown....DC power to gas valve
    Yellow...Ground

    Orange.....high tension wire to spark electrode


    Check that T-stat isn't tripped....'Push to Reset' Button
    Check for DC to t-stats and from t-stats with switch ON

    DC has to get thru t-stats before module will have power
