A FRIEND ASKED ME TO CHECK HIS TRINITY TI200 BOILER. IT IS A NEW INSTALL (BY OTHER) AND THEY CANNOT FIX. I CHECKED IT AND IT WILL RUN FOR A WHILE THEN DISPLAY AN ER6 CODE. I CHECKED COMBUSTION WITH ANALYZER OK, 8.5% CO2 @240 MAXING VALVE . THERE IS 24V BETWEEN F1 AND B WHICH TELLS ME A LIMIT HASNT TRIPPED. CHECKED VENTING AND PIPING AS PER MANUAL OK. FLAME SENSOR HAS GOOD SIGINAL WHEN IM CHECKING IT. THE ONLY THING I CAN THINK OF IS A BAD IGNITION MODULE. I HAVE TRIED TO RESERCH THIS BOILER AS MUCH AS POSSIBLE BUT HAVE NO PREVIOUS EXPERIENCE WITH THE TRINITY. ANY INSIGHT/INFO. OR THOUGHTS WOULD BE GREATLY APPRECIATED. I DONT LIKE TO GUESS AT ANSWERS.

    Check these things. Gas pressure, 7"is best and can not drop below 6" under full fire, even with all other gas units running. Clean the flame sensor. Make sure the condensate is draining out of the heat exchanger ok. Otherwise, it seems like the Fenwal is defective. Would not be the first time.

    THANKS DAVE I DID CLEAN THE FLAME SENSOR AND CHECKED CONDESATE DRAIN. I WILL CHECK THE GAS PRESSURE UPON RETURN DID NOT HAVE SMALL ENOUGH FITTING FOR THE TAP. IM GOING BACK ON MONDAY AND WILL CALL TECH SUPPORT, BUT I FEEL A LITTLE BETTER ABOUT REPLACING THE FENWAL HEARING IT MAY HAVE HAD PROBLEMS. IF YOU THINK OF ANYTHING ELSE PLEASE LET ME KNOW. OTHERWISE WHEN I GET IT FIXED I'LL LET YOU KNOW WHAT THE PROBLEM WAS. THANKS AGAIN FOR THE REPLY.........
