DELAYED IGNITION
Check the following items:
• Check for proper electrode setting.
• Check the insulators for cracks or for a conducting coat of
soot or oil. Cracks sometimes occur under the electrode
bracket, causing a short circuit.
• Check to see that the air shutter isn’t too wide open.
Figure 19 Recommended Electrode Settings.
NOTE: Above 4.00 GPH, it may be advisable to increase
dimension C by 1/8” to insure smooth starting. When using
double adapters: (1) Twin ignition is the safest and is
recommended with settings same as above. (2) With single
ignition, use the same A and B dimensions as above, but add
1/4” to dimension C. Locate the electrode gap on a line midway
between the two nozzles.
FURNACE ROOM ODORS
In the case of furnace room odor, check these
items:
• Check the draft over the fire and make sure
it is at least .02 inches of water column. If
it’s lower than that, check for obstructions
in the flues, or for poor chimney draft.
• Check to be sure that the unit is not being
over fired.
• Check to see that there is not too much air through the
burner.
• Delayed ignition also can be a cause of odors.
