1. Preliminary Checks
a. Sample probe must be inserted sufficiently, and ensure sampling is correct when CO2/O2 readings are measured (refer to Fig.1 for probe position and insertion).
b. Appliance must be operating in service mode at 100% for high fire and 1% for low fire when CO2/O2 values are measured (Fig.2 / 3). Heating circuit should have all  circulation pumps operating, providing sufficient flow through the appliance.

a. Touch simultaneously on the and soft keys for 3 seconds to access the functions for the installer. Reference
b. Menthe in alter access code “054* by using the and . keys to select a digit location and the and  soft keys to change the digit. Touch the soft key to enter the access code.
c. Touch the soft key to highlight the Manual Operation icon then touch the soft key.
d. Touch the soft key while the FAN ‘con is highlighted to manually fire the burner and power the CH circulator(s).
e. Touch the soft key to adjust ch.% firing rate from 1% to 100%. Hold down the soft key to rapidly increase the firing rate.
Once the combustion level is set at high fire (100%), manually place the boiler into low fire (1%) mode by touching the soft key to adjust firing rate down.c. Ensure appliance gas valve reference tube is correctly installed and connected with no kinks or splits (Fig.4).
d. Replace fiber washers with the new ones provided (hardware box) (Fig.4).
e. Ensure gas pipe connections are tight and leak free. See Section 10.5 on page 62 from installation guide.
f. Check the incoming gas pressure at the unit (fig.5) is in accordance with table 2 with all gas appliances in operation and standby.

| Minimum| Maximum
---|---|---
Natural Gas| 5 in w.c.| 13 in w.c.
Propane (LP)| 8 in w.c.| 12 in w.c.

Table 2 – Gas Pressure (inches water column)
g. If CO2 is below specified tolerance (as per table 1) record High fire CO2/O2 in Table 4 – Section 1A & 1B, then follow section 2 and 3 to adjust High and Low fire Combustion.

2. High Fire Adjustment (Throttle)
a. Operate boiler to High Fire 100% in service mode (Fig.6).
b. Alter High Fire adjuster (throttle) (fig.7) in ¼ incremental steps until CO2 is within specified tolerance (as per table 3).
c. Wait for stable combustion reading between each adjustment.

Table 3 – High Fire Adjuster (Throttle)
d. If CO2 levels have reached the limit or high fire adjustment screw (throttle) is fully open, record High fire CO2/O2 in Table 4 – Section 2A).
if no stop can be felt remove gas valve and ensure butterfly valve is open all the way (no white seen) (fig.8).e. Operate appliance to Low fire 1% (fig.9).
f. If CO2 at low fire is below specified tolerance (as per table 1) move to section 3. Low Fire Adjustment.
g. If combustion is within tolerance (as per Table 1) Record Low Fire CO2/O2 in Table 4 – Section 2B and do not adjust low fire Adjuster (offset).

3. Low Fire Adjustment (Offset)
a. Operate appliance at low fire 1% in service mode (Fig.9).
b. Ensure the boiler is at low fire under a stable operating condition whilst monitoring CO2/O2 values.
c. If low fire CO2/O2 values are still below tolerance, record Low Fire CO2/O2 in Table 4 – Section 2B

Table 4 – Low Fire Adjuster (Offset)

Using “T40” torques key/bit (fig 10), unscrew, and remove cap of the gas valve low fire adjustment (offset) (Fig.11).
d. Adjust low fire screw (offset) clockwise in small 1/10 the of a turn adjustments until the CO2 measurement is within the tolerance band but no greater than 1% CO2 increase than the combustion reading after throttle adjustment at low fire (Fig.12). Refer to result recorded in Table 4 – Section 2B.

1% CO2 = 1.8% less O2 on Natural Gas
1% CO2 = 1.5% less O2 on Propane

Valve responds slowly so make smalt 1/10 adjustment to the low fire adjustment screw (offset) and wait for stable combustion reading before repeating.

CO2 measurement should be increased no greater than 1% via low fire adjustment screw (offset) adjustment from previous reading at low fire Refer to result recorded in  Table 2 – Combustion Results summary (column 2-Low fire.)
e. Record Low Fire CO2/O2 in Table 3 – section 3.B.
f. If minimum CO2/O2 is still below allowed specification tolerance contact triangle tube technical support. Tel: (856) 228 8881
g. Operate appliance to High Fire 100% (Fig.6) Record High Fire CO2/O2 in Table 3 – 3.A).
h. Table 2 – Combustion Results summary should be submitted to Triangle Tube technical support

Serial Number:
Date of Installation:

CO2 measurement should be increased no greater than 1% via offset adjustment from previous reading at low fire (column 2. After Throttle Adjustment)
