external temperature sensor is connected (see section
13.1.4), ensure that the calculated temperature (see
section 16.14, parameter
1012
, or parameter
1107
for appliances from 115T to 280T) is higher than the

15.7 - Checking the supply gas
pressure and any adjustments
The gas supply pressure must correspond with the value
that is given in the table in section 18. To check it, proceed
as follows:
1.- close the gas supply isolation valve;
2.- access the inner components of the appliance by
following the procedure in section 17.2;
ORRVHQSUHVVXUHSOXJ³'´VHH¿JXUH
4.- connect to a manometer with a resolution of at least 0.1
mbar. For models from 140T to 280T you can use any
one of the valves;
5.- open the gas supply isolation valve;
6.- make sure the pressure does not exceed 45 mbar;
SRVLWLRQWKHPDLQVZLWFKWR21SDUW³7´LQ¿JXUH
and generate a heating demand by pressing the
key until the maximum value. Make sure the room
thermostat is being called and the system is ready to
dissipate the heat generated;
8.- Set parameter
2200
to
HIGH
(in the 60T and 70T
models, use parameter
2010
). The burners will now
work at maximum output heat for 20 minutes;

that the gas supply pressure does not drop below 10
mbar. If the pressure is lower, do not attempt to adjust
the appliance; you must rectify the supply pipework to

be adjusted as part of either the conversion procedure
detailed in section 15.4/15.5 or the adjustment
procedure detailed in section 15.8.
After having made sure the gas pressure is correct:
1.- Reset parameter
2200
to
OFF
(in the 70T model use
parameter
2010
).
2.- close the gas supply isolation valve;
3.- disconnect the manometer and close pressure plug “D”
again;
