tion wire and proper grounding and wiring. Turn power back on. Repeat Step 3. If there is still no spark after several attempts the igniter may be misaligned;

5.Check to see if igniter is grounded out by pulling the spark wire and doing a continuity check between the igniter and burner. If the igniter is grounded out, it must be realigned. Remove the burner. Loosen the igniter nut, locate the igniter in the center of the burner head and tighten igniter nut. Confirm it is centered and reinstall burner head;

6.If you have spark, turn off unit;

7.Turn on power. Unit will pre-purge 40-45 seconds and move onto ignition trial. You will hear a click

from pilot gas valve (you will not hear the spark- ing);

8.The pilot may not light at first trial; leave the unit running until you have pilot. If you still do not see pilot over 90 seconds; turn off the unit; repeat steps 6-8;

9.Check pilot manifold pressure, Location (4). Compare the reading to the value listed in the tables;

10.Check pilot flame; 8 distinct circular blue flames around the center of the pilot;

11.Replace the cap for pilot manifold adjustment screw; do not over-tighten.
