of the adjustments. After adjusting the screw wait a moment for the combustion levels to stabilize before
attempting to make any further adjustments. Continue this procedure until combustion levels are satisfied.
Reset the Target Temperature to normal operating conditions on the BTC 1 Controller.
To adjust the low fire setting
Observe the Boiler Inlet Temperature. Set the Boiler Target temperature so that it is 10
Inlet Temperature. The boiler will begin to modulate to low-fire as setpoint is being reached. The actual
modulation rate can be shown on the screen as Modulation, this will be shown as a percentage. Low-fire
is achieved at 25%.
The MicoFlame will respond immediately and operate at low fire. When this is achieved locate the low fire
adjustment screw as illustrated in Figure 28. Using a flat screwdriver rotate clockwise to increase CO
levels and counter-clockwise to decrease CO
replace the screw cap back on to the gas valve.
