4. Open the burner box access panel.
For Sentinel Brood Heaters:
To allow easy access to the pressure tap plug at
the gas control’s outlet, remove the two screws that
hold the valve’s mounting bracket to the top of the
burner box . Rotate the valve as needed for removal
of the pressure taps. See Fig. 34.
-- Regardless of brood heater, if connector (Fig.
33) is occupied by thermostat wiring, remove the
air inlet from the burner box and route the gauge
tube through the inlet to the outlet of the gas
control valve. See Fig. 35.

5. Close and latch the burner box. Open the fuel supply
valves to the brood heater, reconnect the brood
heater’s electrical supply, and start the brood heater.
B. Reading Pressures
1. With the brood heater operating, the pressure
gauges should read the pressures speci
fi
ed on the
dataplate.
2. Do the readings at the inlet and outlet pressure
gauges agree with that speci
fi
ed on the dataplate?
If so, then no further checking or adjustment is
required. Proceed to section D.
3. If the inlet pressures do not agree with that speci
fi
ed
on the dataplate, then the regulator controlling gas
pressure to the brood heater requires adjustment.
4. If the inlet pressure is correct but the burner manifold
pressure does not agree with that speci
fi
ed on the
dataplate, then the pressure regulator internal to
the gas control requires adjustment. Refer to the
following instructions. The burner box will need to be
opened and closed/latched as needed to accurately
set the gas control pressures.
C. Setting the Gas Control
Set the thermostat to its highest setting. The single am-
ber light on the burner box panel will come on, and gas
control will open. If manifold gas pessure is different
than dataplate, adjust the internal pressure regulator
clockwise or counterclockwise. See Fig. 36.
