I have an SBN 1000 
Continually getting Flame Loss While Running on lower heat exchanger only.
Been cleaned and practically rebuilt.
New gas valve,  New blower, New igniter,New Flame sensor.  Checked all grounds and gas pressures ?
I'm baffled ?
Thanks

    I would start here.
    It's odd Lochinvar doesn't want Hi and Lo fire tests. Maybe it's because I only see boilers up to 400K input.
    Is the display able to capture the flame loss? Does it say blower RPM, percentage input, flame rectification, etc., at the time of the flame loss?
