VAC to 24 VAC for operation of the the ignition control.
Without 24 VAC from the transformer, the red diagnostic
light will not be on and the ignition control will not
function.

Gas Pressure Checks
Ŷ The following explains a typical procedure to be
followed in checking gas pressures.
Ŷ The gas pressures will vary depending upon fuel type.
Consult the dataplate on the brood heater or page 4 in
WKLVPDQXDOIRUVSHFL¿FSUHVVXUHVWREHXVHGLQFRQMXQF -
tion with this procedure.
Gas pressure measured at the inlet to the gas valve is
Inlet Pressure and gas pressure measured at the outlet of
the gas valve is Burner Manifold Pressure.
A. Preparation
1. Obtain two pressure gauges capable of reading up to
9 kPa in. W.C.
2. Disconnect the heater from the electrical supply and
close the fuel supply valve to the brood heater inlet.
