Operation; Maintenance; Important Recommendations - Baxi P-30 Serie Betriebs-, Reiniguns- Und Wartungsanleitung Für Den Benutzer

GB
The P-30 boiler which you have chosen for your
installation is basically made up from cast iron
sections and so is a product of unbeatable quality
that will provide you with the level of comfort that
you expect from individual central heating.
In this information we offer you the main features
of the boiler as well as the operations that are
necessary for its correct performance and proper

maintenance.

Operation

Checks and operations to be followed at the
beginning and end of every heating season, as
well as during the boiler's service.
Operations prior to the fi rst lighting
- Check that the installation fl ow and return cocks,
if there are any, are open.
- Check that the installation is full of water and that
the fi xed pointer in the hydrometer or combined
temp./altitude gauge has been placed by the
installer in the position which corresponds to
the static head of the installation. 1 bar = 10
metres.
- Check the pump for correct operation. To do this,
remove the turn and bleed control plug (10) with
a screwdriver and look at the shaft*.
* After long periods of non-use, the pump may have
become jammed. In this case, press a screwdriver
into the slot on the shaft-end and at the same time,
turn it.
- Bleed the air from the installation and radiators.
- In installations with a closed expansion vessel,
top up with water (if necessary) until the mobile
pointer in the hydrometer or combined temp./
altitude gauge is slightly above the fi xed one.
Where an open expansion vessel has been
installed, refi ll until the mobile pointer levels off
with the fi xed one.
First lighting with solid fuels
- Check that the damper (11) in the smokehood
(12) is open; Otherwise, open it by turning
the handle (13). Get the end of the handle
(13) to point at the letter "A" (open) on the
smokehood.
- Open the ashpit door (8) by turning its handle
(14).
- Lower the front section grille (15) hinged on
the built-in section brackets (16) and leave it in
inverted position.
- Put a suffi cient amount of small fi rewood or coal
on the grate bars (17) so as to aid lighting up.
While doing this, keep the charging door (7) and
the observation window (18) closed.
- Turn on the switch (1) to put the circulating pump
into operation.
- Following the fi rst combustion, put the grille (15)
back in position and close the ashpit door (8).
- Open the charging door (7) and fill the
combustion chamber to an appropriate level
with the fuel you have decided to use. Close
the door and check that there are no leaks of
fl ue gases.
- Adjustment of the automatic temperature
regulator (6) must have been done by the
installer. However, if it should be adjusted now,
follow the relevant instructions enclosed.
- Bleed all the radiators and ensure that they all reach
the required operating temperature in accordance
with that selected on the regulator (6).
First lighting with fl uid fuels
- Check that the damper (11) in the smokehood
(12) is open; Otherwise, open it by turning
the handle (13). Get the end of the handle
(13) to point at the letter "A" (open) on the
smokehood.
- Turn on the main switch for the power supply to
reach the control panel (19).
- Turn on the switch (1) to put the system pump
into operation.
- Turn on the switch (2) on the control fascia to put
the burner into operation and check its running
against the instructions that are delivered with
it.
- Set the control thermostat (3) on the control
fascia to the desired temperature. It is
recommended that it should at least be 60°C.
- If the installation has an ambient thermostat, set
its dial in the position selected for the previous
one.
- Bleed all the radiators and ensure that they all
reach the required operating temperature in
accordance with that selected on the control
thermostat (3).
Cleaning
The cleaner the boiler is kept the lower will fuel
consumption be. For every millimetre of soot on
the interior surfaces, consumption increases by
approximately 3%.
To aid operating and cleaning the boiler, a set of
stoking tools is supplied with it, comprising:
20 - Shovel.
21 - Scraper.
22 - Slice Bar.
23 - Flue Brush with handle.
The shovel (20) is used both to charge the boiler
with solid fuels and to remove the nonburned
residues from the ashpan.
The scraper (21) is used to drag the ash and
clinker which may have dropped onto the base
of the boiler to a more accessible location for
collection and removal.
The slice bar (22) aids cleaning the grate bars
in such a way that the nonburned residues may
drop into the ashpan. If necessary, it can be used
to poke the solid fuels.
The brush (23) is used to clean the fl ues and the
interior surfaces of the boiler walls
Use of solid fuels
Before charging:
- Open the ashpit door (8) through its handle (14),
lower the front section grille (15) as described
in point 8 of the "First lighting with solid fuels"
section and use the slice bar (22) to remove the
nonburned residues from the grate bars, which
will drop into the ashpan (24).
- Put the front section grille (15) back in position,
withdraw the ashpan (24) and, with the aid of
the shovel (20), empty it. Put an empty ashpan
in its place and close the ashpit door.
At regular intervals* carry out the following
operations:
- Open the charging door (7) and, with the aid of
the brush (23), clean the smoke fl ues (25).
* The frequency of this regular cleaning procedure
will depend on how much the boiler works and the
type of fuel used.
- Loosen the wing nut (26) to detach the cleaning
cover from the smoke hood (12) and remove the
soot inside it.
- Insert the brush (23) between the charging and
ashpit openings on the front section and clean
the interior surfaces of the sections that make
up the combustion chamber.
Use of fl uid fuels
At regular intervals carry out the following
operations:
- Turn off the main switch to isolate the system.
- Close the fuel inlet cocks to the burner.
- Open the burner door (9) loosening the locking
screw (27) and protect the burner so that it does
not get dirty.
- Open the charging door (7), lift the baffl e plate
(28) and remove it for cleaning.
- Insert the brush (23) between the charging and
burner openings on the front section and clean
the interior surfaces of the sections that make
up the combustion chamber.
- Loosen the wing nut (26) to detach the cleaning
cover from the smoke hood (12) and remove the
soot inside it.
* The frequency of this regular cleaning procedure
will depend on how much the boiler works and the
type of fuel used.
Maintenance
- At the end of each heating season or before
a long period of non-use, the boiler should
be thoroughly cleaned without letting the soot
harden.
- Check, at least once a year, the correct running
of all control and safety devices.
- Carry out, at least once a year, the operations
contained in the instructions which come with
the burner.
- Clean the chimney at least once a year.

Important recommendations

- In case of long periods of non-use, the
installation must not be emptied.
- Water should be added to the system only when
absolutely necessary.
This operation should be done when the
boiler is cold.
- Frequent adding of water can form lime deposits
on the boiler, causing serious damage, and at
the same time reducing effi ciency.
- If the installation is located in an area with risk
of freezing, some anti-freeze product should be
added to the water in proportion to the minimum
outside temperature of the place.
How to solve some malfunctions which may
arise after long periods of non-use.
- The radiator or panel circuit does not warm up,
even when the temperature of the water in the
boiler is correct. Check that:
- The circulating pump is rotating correctly;
otherwise, proceed as indicated under
"OPERATION".
- The valves on each radiator are open and
their spindles (headworks) are not jammed.
- The burner does not light up. Check that:
- The control (3) and ambient thermostats are
set to the right temperature.
- The installation fuses are the correct ones
and the main switch is ON.
- Voltage is reaching the control panel.
- The safety limit thermostat (4) has been
activated. To reset it, unscrew the protection
plug and press the lug inside.
If after these checks no positive result is obtained,
report it to your installer.
