4.5 Starting up the water heater
Once the system has been filled,
proceed as follows:
Check that the exhaust flue is free
of obstructions and correctly
connected to the water heater;
Switch on the power supply to the
appliance;
Open the gas isolation valve;
Place switch 1 in the ON position
(see 2.7 “Control Panel”)
, after a
few seconds the circulating pump
will start to run;
Use button 6 to set the D.H.W,
HEAT or D.H.W./HEAT function. The symbols will light up
(fixed light) to indicate that the water heater is working;
The automatic ignition system will then light the burner. This
operation is repeated for 3 times. It may however be necessary
to repeat the operation in order to eliminate all the air from the
gas pipes. To repeat the operation, wait approximately three
minutes before re-attempting to light the water heater. To reset
the water heater Switch off switch
1
(see 2.7 “Control Panel”)
and switch it back on again and repeat the lighting procedure;
With the water heater ignited, if the system still emits noises, the
operations must be repeated until all the air has been removed
from the gas piping;
Check the water pressure in the system. If the pressure has
fallen, introduce water into the appliance until the code
“H2O”
disappears on the display and the pressure gauge reads in
the Green section of the gauge (14.5 psi (1 bar)) on completion;
Check gas pressure at gas valve inlet pressure tap. SEE Fig 2.
Set gas pressure to proper level at the regulator (Refer to
section 2.1 Technical Data). Gas pressure adjustments must be
performed while the appliance is in “Flue Test Function” mode
(maximum firing rate). Do NOT make any adjustments to the
gas valve itself.
Unscrew the plug and insert an analyser in the exhaust
sampling point
PF, SEE Fig. 1, (air intake manifold is missing in
the drawing to provide a clear view of the V screw) to check the
CO2 value. Make sure that the value complies with that reported
in table 1
while the appliance is in “Flue Test Function” mode;
If the CO2 value does not correspond to the specified value,
adjust screw
V (see fig. 1) on the venturi clockwise to reduce the
CO2 value or counter-clockwise to increase it
;
