TROUBLE
POSSIBLE CAUSE
SOLUTIONS
Brooder is not
glowing red…
The supply gas pressure is too
low.
Improper size of gas piping.
The orifice is clogged.
Incorrect orifice size.
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.
Brooder will
not attain the
desired
temperature…
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.
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.
Flames flaring
up, outside of
emitter
surface…
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.
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.
