TRX Series II - Installation - Startup - Maintenance Instructions
Part 11 - Start-Up
Make sure the calibrated combustion analyzer is set to the
appropriate gas type. Failure to do so could result in serious
personal injury or death.
It is required to use a calibrated combustion analyzer to verify
final adjustment according to the combustion chart (Table 43).
Failure to do so could result in serious personal injury or death.
It is very important that the combustion settings are within the
ranges listed in Table 43. Visually looking at the burner does not
determine combustion quality. Failure to measure combustion
with a calibrated combustion analyzer and set the throttle within
the recommended combustion measurements could result in
property damage, severe personal injury, or death.

Adjusting the Gas Valve at Max Power (100%)
Adjust the gas valve by turning setting screw 4 clockwise to increase
the CO2 level; counterclockwise to reduce the CO2 level (1 turn
adjusts the CO2 level by approximately 0.3%). Wait 1 minute after
each change in setting for the CO2
value to stabilize.
If the value measured corresponds to
the value given in the Table 43, max
adjustment is complete. Otherwise
continue the setting procedure.
ATTENTION!! The Test Function
will automatically deactivate after
30 minutes, or Test Function can be
turned off manually by pressing the
RESET button.
OPERATION 4
CHECKING THE CO2 AT MIN POWER (10%)
From the Burner Test screen, turn the dial to select MIN POWER and
press ENTER to operate the boiler at minimum power.
Wait 1 minute for
the boiler to stabilize
before carrying out the
combustion analyses.
If the CO2 (%) reading
at Min Power is outside
the range indicated
in Table 43, adjust the
gas valve following
the instructions below.
Otherwise proceed directly to OPERATION 5.
NOTE: Min Power calibration must be performed after Max Power
calibration.
NOTE: The CO2 at Min Power (10%) must not be set higher than the
CO2 reading at Max Power (100%); it may be set lower by as much as
0.3%
