14 - START-UP
14.8.2 - Check the CO2 content and make
any necessary adjustment on appliance
models 100T to 280T
WARNING! If during this procedure a CO
value of more than 1000 ppm is detected, turn off the
appliance and contact the manufacturer.
1.- If one is not already present, you will have to make a hole
for the combustion analysis, located about 200 mm from the
exhaust gases outlet pipe (see figure 14-9 corresponding to
stopper “F”).
2.- Turn on the appliance and open the link between terminals
“10” and “11”;
3.- Make sure that the temperature demanded is higher than
that of the appliance;
4.- Go into the installer menu (see section 15.9) and set
parameter
2201
to
HIGH.
Now the MASTER burner will
operate at maximum power for 20 minutes;
5.- Wait two or three minutes for the CO2 to stabilise;
6.- Insert the sensor to read the value of CO2 in point “F” shown
in figure 14-9;
7.- Compare the value of CO2 detected with that shown in
table 14-8; make sure you read the value for the type of gas
being used. If the value of CO2 is not as shown in table 14-
8, you must correct it using screw “E” in figure 14-10. Using
a 2.5 mm six-sided spanner (turn the screw clockwise to
reduce the value of CO2 and anticlockwise to increase it),
make small turns, always waiting for the value to stabilise
before continuing with further movements, until you reach
the desired value.
8.- Once you have reached the correct value of CO2 as in table
14-8, seal the screw with red paint or a similar system to
discourage any tampering with it.
9.- Set parameter
2201
to
LOu
. Now the MASTER burner
will operate at minimum power for 20 minutes.
10.- Wait two or three minutes for the CO2 to stabilise;
11.- Compare the reading for the value of CO2 with that shown
in table 14-8, make sure you read the value for the type of
gas being used. The value of CO2 must fall within the values
shown, if that is not the case you must turn of the appliance
and contact the manufacturer.
WARNING! The CO2 reading at minimum power
could be influenced by the chimney draught. This is
deduced when the CO2 value is rather low compared to
the value at high power. In this event it is necessary to
take the CO2 reading by removing the flue gas sensor
from the corresponding burner and inserting the
analyser sensor into the hole
12.- Set parameter
2201
to
OFF
;
13.- Work on the remaining burners, repeating the steps
from point “3” to point “11”, bearing in mind that parameter
2202
acts on burner 2,
2203
on burner 3 and
2204
on burner 4.
14.- Close the combustion analysis hole in figure 12-2, with
a suitable stopper “F” as shown in the manufacturer’s
instructions for the outlet pipe.
WARNING! Once stopper “F” is in position with
the appliance at maximum power, check there are no
leaks of exhaust gases that could cause damage.
14.9 - Check appliance power
The appliance’s air/gas mixture ratio is set at the factory. The
gas pressure at the burner is controlled indirectly by the fan.
The only way to check the appliance’s power is to act directly
on the gas meter. Proceed as follows:
1. Turn on the appliance by moving the general switch (detail
“T” in figure 15-1) to ON and set off a heating request by
taking the temperature requested to the maximum using key
, making sure that the system is capable of dispersing
all the heat generated.
2. For models 60T and 70T, set parameter
2010
to
HIGH
.
For the other models set parameter
2200
to
HIGH
,
now the appliance will operate at maximum power for 20
minutes.
3. Measure the gas flow rate at the meter. The value obtained
must be compared with the value given in section 17 under
the heading “Gas flow rate” with a tolerance of + 0 - 10%.
4. If the gas flow rate is lower, check:
a) That there are no obstructions in the air intake and flue
gas outlet ducts;
b) That the lengths of the air intake and flue gas outlet ducts
correspond with what is shown in section 17;
c) That the air intake filter (detail “11” in figures 3-3, 3-5 and
3-7) is clean;
5. If the gas flow rate falls within this margin, set parameter
2200
to
OFF
. In appliance models 60T and 70T, set
parameter
2010
to
OFF
to return the appliance to normal
operation;
6. If the gas flow rate is higher, repeat the process described
in section 14.9.
14.10 - Minimum water flow rate
The appliance has a system to protect against low water
flow rate. The water flow rate gauge (detail “16” in figure 3-1)
constantly measures the flow rate on each exchanger. If the
flow rate falls below the value of the “Minimum operating water
flow rate” described in section 17, the appliance will turn off
automatically and, after three minutes, if the flow rate does not
go up, the relative error will appear on the display.
14.11 - Check operation of
control thermostat
After starting up the appliance adjust the temperature on the
control thermostat to a lower value than the actual temperature
of the water in the swimming pool: make sure the appliance
has turned off.
14.12 - Check intervention
of safety thermostat
After starting up the appliance adjust the delivery temperature
to the maximum possible value (see section 15.5). Check that
intervention of the safety thermostat turns off the appliance.
