Gas Pressure Setting Procedure; 201Fa, 263Fa, 263Faii - Rinnai RHFE-551FA Service Manual

Gas Pressure Setting Procedure

1. Turn off the gas and the power supply.
2. Hold both ends of the bottom cover (undercover
assembly) and pull toward you to remove the
cover. Cover snaps in place.
3. Remove the 7 screws that hold the front panel
and the louver assembly to remove panel from
the unit. Pull the panel out at the bottom about 4
inches (100 mm) and lift up over clips that hold it
in place at the unit's top.
4. Remove two test point screws (1/8 NPT tap) with
3/16 Allen wrench and attach the manometer to
both test ports. Both ports must be used in order
to measure the differential pressure. Ensure that
the manometer is properly calibrated.
5. Turn on the gas and power supply to the
appliance. With the unit in the Off position, press
the SW1 switch at the top of PC board until it
beeps.
