1. If P1 CO2 level is off:

BLoosen yellow painted philips screw (1) and cover should rotate down (2) revealing a recessed brass slotted screw. Fig. 42.

B Turning the slotted screw counter clockwise will raise P1 CO2 levels and clockwise will lower P1 CO2 levels. Adjustments to the slotted screw will also change P2 CO2 levels.

BAfter bringing the P1 CO2 readings in range, press

the button to enter the P2 mode. Verify CO2 readings in P2 mode.

B. Measuring CO2 (Cover Installed):

BOpen all hot water taps to achieve a flow rate of at least 4 gallons per minute. (1 tub and 2 sinks should be sufficient).

B Record the CO2 reading in P1 below. (Analyzer reading may take several minutes to stabilize).

BPress the ‘ ’ button until P2 appears. Unit will ramp down to low fire and the water flow should decrease.

C. Adjusting CO2 (cover removed):

Note: when making adjustments with the front cover off, CO2 values will be 0.3 - 0.5% lower than with the front cover on. Adjust values accordingly to make target num- bers in Table 10 when cover is secured.

Compare your readings to those found in Table 10. If CO2 readings are off, make adjustments as outlined below.

Note: P1 adjustment will change the P2 reading. Con- firm the P1 value BEFORE adjusting the P2 level.

2. If P2 CO2 level is off:

BRemove yellow painted #40 Torx cover from the front of the gas valve. (Fig. 43) A plastic #40 Torx screw will be revealed.

B Turning the plastic #40 Torx screw counter clockwise will lower P2 CO2 levels and clockwise will raise P2 CO2 levels.

Note: These screw adjustment are very sensitive and may take several minutes to stabilize.
