12.0) TROUBLESHOOTING
A) SPARK ELECTRODE INSPECTION
1. Inspect the spark electrode for possible cracks in the
ceramic insulator. Replace if necessary.
2. Check for proper electrode spark gap. This should
measure 1/8". Re-bend to correct gap or replace
electrode if necessary.
3. Check that the electrode ground rod is located to
center of the burner port as shown in illustration. If
electrode is misaligned, loosen the screws and nuts
holding the electrode and reposition to correct location.
Re-tighten screws and nuts.
B) TROUBLESHOOTING CHART
TROUBLE
Brooder is not
glowing red...
Brooder will not
attain the desired
temperature...
Flames flaring up,
outside of emitter
surface...
POSSIBLE CAUSE
The supply gas pressure is too low.
Improper size of gas piping.
The orifice is clogged.
Incorrect orifice size.
There is insufficient heat in the building
for heat loss (i.e., not enough brooders).
The thermostat sensing bulb is
incorrectly placed.
The thermostat is out of calibration.
The gas pressure is too high.
Incorrect orifice size.
Incorrect type of gas supplied to the
brooder.
Not enough combustion air.
Check the manifold gas pressure and
adjust if necessary.
If you are not sure of the performance,
use the NFPA 54 gas pipe sizing table in
these instructions.
Clean the orifice.
See the instructions for correct orifice
size and replace if necessary.
Conduct heat loss and add brooders or
other source of heat as necessary.
Reposition as necessary for proper
operation. NOTE: The sensing bulb
should be shielded from direct radiation
to prevent short cycling of the brooder.
Recalibrate (if possible) or replace.
Check the manifold gas pressure and
adjust if necessary.
See instructions for correct orifice size
and replace if necessary.
Check the nameplate to identify the
correct type of gas the brooder is
equipped to operate using.
Clean the inside of the burner with a wire
brush and blow out with compressed air.
