2.- Put the appliance in stand-by, shutting down all heating
demands (remove the room thermostat bridge, if any, or
adjust the heating setpoint to off using the
key).
3.- Make sure that the required temperature is higher than the
boiler/water heater temperature;
4.- Access the installer menu (see section 16.15) and set
parameter
2201
to
HIGH.
The MASTER burner will now
work for 20 minutes at maximum output heat;
5.- Wait for two minutes to allow the CO

stabilise before continuing, until you reach the desired value.
8.- Once the correct CO

value as per table 15-8 has been
reached, seal the screw with red paint or a similar system
to discourage tampering.

15.9 - Checking appliance heat input
The appliance has a factory set air/gas mixture ratio. The gas
pressure to the burner is indirectly controlled by the fan. The
only way to check the appliance heat input is to directly use a
gas meter. Proceed as follows:
1. Switch the appliance on by turning the main switch to ON
SDUW³7´LQ¿JXUH
and create a heating demand, bring
the requested temperature to the maximum value via the
key, making sure that the system is able to dissipate
all the heat generated.
2. For the 70T model, set parameter
2010
to
HIGH
. For
all other models, set parameter
2200
to
HIGH
. The
appliance will now work for 20 minutes at maximum input.
