 Use adapter kit #0151K00000S to measure gas
pressure on White-Rodgers 36J54 gas valves.
Only small variations in gas pressure should be made by
adjusting the gas valve pressure regulator. The manifold
pressure must be measured with the burners operating. To
measure and adjust the manifold pressure, use the following
procedure.

2. If installing a communicating fossil fuel system, make
sure the 1,2,R,C terminal is either removed or there are
no wires connected. If utilizing an accessory module to
control a non-communicating heat pump, disconnect the
RJ12 jack from the furnace.
3. Provide power to the furnace.

4. Provide a thermostat W call and allow furnace to begin
its ignition sequence.
5. Remove thermostat W call and allow furnace to enter idol
state (7 segment display IdL).
6. Provide the thermostat W call again. The furnace will now
operate in low stage for greater than 5 minutes (assuming
the target run time has been set to something greater than
10 minutes).
7. When test is complete, remove the W (heat) call to the
furnace. The system will shut down.
