The P-10 boiler that you have chosen for your installation is
basically made up from cast-iron sections and so it is a product
of unbeatable quality that will provide you with the convenience
of individual central heating for many years. You will obtain
the level of comfort that you expect from its use.
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.
We are at your disposal through your Installer to solve any
problem that might arise.

Operation
Checks and operations to follow at the beginning and end of
each heating season, and also while using the boiler.
Operations prior to the first lighting
1 - Check that the installation flow and return cocks, if there
are any, are open.
2 - Check that the installation is full of water and that the fixed
pointer on the altitude or combined temp./altitude gauge
has been placed by the Installer in the position which
corresponds to the static head of the system.
(See figure)
3 - 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.
4 - Bleed the air from the installation and radiators.
5 - In installations with a sealed expansion vessel, top up with
water (if necessary) until the mobile pointer on the altitude
or combined temp./altitude gauge is slightly above the fixed
one. Where an open expansion vessel has been installed,
refill until the mobile pointer levels with the fixed one.
First lighting with solid fuels
6 - 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.
7 - Open the ashpit door (8) by turning its handle (14) .
8 - Lower the front section grille (15) hinged on the built-in
section brackets (16) and leave it upside down.
9 - Put a sufficient amount of straw or paper, kindling or coal
on the grate bars (17) so as to aid lighting up.
While doing this, keep the firedoor (7) and its observation
window (18) closed. The latter will be kept open only when
using fuel with an excessive content of volatile material
requiring a secondary supply of air for burning.

10 - Switch on the system circulating pump.
11 - Following the initial combustion, put the grille
(15) back in
its original position and close the ashpit door (8) .
12 - Open the firedoor and stoke with the chosen fuel, loading
it so as not to smother the fire, to an appropriate level.
Close the firedoor and check that there no leaks of flue
gases.
13 - Adjustment of the automatic damper regulator (6) will have
been done by the Installer. Nevertheless, if you have to
set it, proceed according to the instructions that come with
it.
14 - Bleed all the radiators and ensure that they reach the
required operating temperature in accordance with that
selected on the damper regulator
(6) .
First lighting with fluid fuels
6 - 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.
7 - Turn ON the main switch for the power supply to reach
the control panel (19) .
8 - Turn ON the switch (1) on the control panel to start up the
system pump.
9 - Turn ON the switch (2) on the control panel to start up the
burner and check its running against the instructions that
come with it.
10 - Set the control thermostat (3) on the control panel to the
required temperature. A minimum temperature of 60 ºC
is recommended.
Where an ambient thermostat has been installed, set its
dial in the position corresponding to the chosen indoor
temperature.
11 - Bleed all the radiators and ensure that they 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 thickness of soot adhering to its interior
surfaces, consumption increases by approximately 3%.
To aid operating and cleaning the boiler, a set of tools is
supplied, comprising:
20 - Shovel
21 - Scraper
22 - Slice bar
23 - Flue brush & handle
The shovel (20) is used in stoking the boiler, for putting solid
fuel in the combustion chamber, as well as for gathering and
withdrawing cinders from the ash-pan.
The scraper
(21) permits drawing ashes and slag which might
have fallen on the base of the boiler, from the back to a more
accessible place for gathering and withdrawing.
The slice bar
(22) eases cleaning of the grates in such a way
that with its help the cinders which have remained on the surface
can fall onto the ash-pan. It can also be used –if necessary–
for stirring up the solid fuel.
The flue brush
(23) is used for cleaning the flues and the interior
walls of the boiler.
Using solid fuels
Before each stoking proceed to:
1 - Open the ashpit door
(8) using 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 cinders from the grate bars, which will drop into
the ash-pan
(24) .
2 - Put the front section grille (15) back in position, withdraw
the ash-pan (24) and, with the aid of the shovel (20) , empty
it. Replace the empty ash-pan and close the ashpit door.
