It may be necessary to go back and forth between HI Fire and LOW Fire several times (and making
adjustments ONLY at LOW Fire), before CO
2
at both are within acceptable levels. Be sure to put the
cap screw back onto the gas valve adjustment port when done.
23.
Once the CO
2
and manifold pressure measurements for both MIN and MAX Fire are acceptable per
Table D, set DIP switches 6 and 7 to the OFF position for Nominal Fire (normal operation). The FT is
now operating in it’s normal mode.
24.
Write in the correct Conversion Date and the Technicians Name to the included gas conversion sticker.
See Figure F. Then apply that sticker adjacent to the rating plate.
25.
Remove your combustion Analyzer from the combustion test port and be sure to thread the test port plug
back into position.
26.
Re-connect outdoor reset if it was disconnected previously in this conversion and put the Front Panel
