1, part 2g
(models up to 400 kW output)
The CE Declaration and CE Certificates are
available and can be downloaded from our
website www.baxi.es
Note:
The manufacturer responsability concerning the
CE marking is subject to be used the BAXI burners
showed in the CE Certificates or any other burner
of the market with the CE marking and with a
firing rate suitable to the working conditions and
technical features explained in this manual.
Notes relating to the burners
Boilers with an output lower than 400 kW
(CPA 55-BTH to CPA 380-BTH models), are
delivered without burner because according to
the Comission Regulation Nº813/2013, they
are a product intended for replacing the existing
CPA boilers in the market. However, the boiler
are ready for assembling the BAXI burners
recommended in Table 1. For the use with other
burners, the following remarks must be taken
into account:
-
Burners must be according to EN
267 (with oil) or EN 676 (with Gas) and the
EEC Directives (Electromagnetic Compatibility
2004/108/EEC, Low Voltage 2006/95/EEC,
Machinery 2006/42/EEC) and Gas 2009/142/
EEC)
-
The boiler has a burner plate in the door
with the dimensions showed in fig.28
-
The burner must have an useful
working field suitable for the combustion chamber
overpressure showed in Table 1.
-
The height above sea level where the
boiler is installed must be taken into account as
well, due to a decrease of the air density and
consequently a lower quantity of the required
oxygen for the combustion.
Technical specifications and
dimensions
In Table 1 is summarized the main technical
parameters for the range an in the Fig.1 is
showed the general dimensions for the boilers and
details about hydraulic connexions and chimney
connection
Installation
When installing the boiler, the following MUST
be observed:
– The installation position must be in the form of a
fireproof base which must be smooth and level
and capable of supporting the weight of the
boiler when full of water. Dimensions for boiler
bases are shown in Fig. 2.
– The boiler plantroom and the ventilation
provision must comply with the requirements
contained in the Regulations for Central Heating
Systems.
– The chimney shall be constructed in accordance
with current standards and should take into
account the requirements of local regulations on
chimney heights. Guidance on chimney sizing
is given in the graph Fig. 3.
– When fitting approved chimneys, the
manufacturer’s specifications must be observed.
Chimney Selection Graph. Fig. 3
Example: Find out the inside diameter of a
chimney for a CPA 540-BTH and 15 m
high.
According to the graph: Diameter = 36 cm.
In any case, the recommendations of the chimney
manufacturer, must be taken into account.
Assembly
Once the boiler has been set into place, follow
the operations described below:
1 – Open the boiler door and remove the
protective cardboard from the insulating fibre
on it. Remove all the material contained in the
combustion chamber (control panel, boiler
body insulation, cleaning brush and door
clamps).
2 – Fit the clamps (1) with their backnuts (2) in
the door. See Fig. 5.
3 – Check that the opening direction of the door
is the one required. On the other hand, if you
want to reverse it, proceed as follows:
3.1 – Make sure the door is correctly fastened
with the clamps (1) and hinge tie-rods
(3).
3.2 – Transfer the M4 bolts (4), which locked
the hinges on the side where the
clamps were initially, to the opposite
side (5) where the clamps will remain
permanently. See Figs 6 and 7.
3.3 – Exchange, diagonally, each clamp (1) for
a hinge tie-rod (3), keeping in each case
the respective backnuts. See Fig. 8.
3.4 – Tighten the two backnuts (6) on the
hinge side.
3.5 – Remove the door switch (7) and install
it on the opposite side.
4 –
IMPORTANT
The door will be adjusted in this mounting
position so as to prevent flue gases from
leaking.
(This adjustement should be made before
fitting the door casing panel and the burner).
To adjust the door, for making sure that it is
gas-tight, proceed as follows:
Likewise, loosen the backnut (2) on the side
of the door clamps. Fig. 25.
Tighten the two hinge tie-rods (3) in parallel
with the two clamps (1) until the whole outline
of the door sinks about 2 to 3 mm in the
sealing strip.
5 – Place the pocket (9) for the thermostat and
thermometer bulbs in the socket (10) of the
heating flow pipe (11).
In models with basic control panel (one or
two stage operation), place the check valve
(12) of the combined temp./altitude gauge in
the socket (13) of the return pipe (14). In both
cases put teflon or something similar on the
thread to ensure water tightness. See Fig. 9.
6 – Make the flow (11) and return (14) connections
from the boiler to the heating installation.
7 – Make the safety and drain connections (15)
in accordance with the type of installation:
7.1 – Sealed System Installation. Fig. 10
Where the hydraulic installation is to
be sealed and pressurised, a safety
valve (16) must be connected to the
upper tapping (17) adjacent to the flow
connection. Under no circumstances
must the setting of the safety valve
exceed 5 bar or the maximum pressure
allowed by the expansion vessel. The
discharge pipe should be connected via
a funnel (18) to the drain.
A tapping is provided for connection
of an expansion vessel (19) via a tube
(20) to the underside of the boiler body.
An automatic air vent (21) should be
installed to bleed the air in the tube (20).
7.2 – Open Vented Installation. Fig. 11
Where the hydraulic installation is to be
open vented, the vent pipe (22) should
be connected to the upper tapping (17)
and the cold feed pipe (23) must be
connected to the connection (20) at the
base of the boiler body.
8 – Fill the installation with water and test for
water tightness, checking that there are no
leaks. Drain/flush the installation to remove
debris and then refill.
Main features
The CPA-BTH boiler is a heat generator with
reverse flame and efficiency in excess of 93%
(nett).
The main material used in the construction of this
boiler is steel sheet. The material, methods of
welding, method of construction and dimensions
according to the existing regulations in the EEC.
Key features of the CPA-BTH boiler are the top
located Flow and Return connections and the
reversibility of the combustion chamber door,
which can be easily adapted for left or right hand
opening according to the needs of the installation.
From model CPA 70-BTH, boilers are fitted
with an explosion relief gate situated in the
smokehood. All models feature a door opening
safety switch.
The boiler flue tubes are fitted with spiral-type
turbulators with the leading part manufactured
from stainless steel (except CPA 55, 70 y 100-
BTH), which provide the necessary resistance
to the passage of the products of combustion to
achieve high operating efficiency.
The boiler body is insulated with a 70 mm-thick
insulating blanket. The boiler is suitable for oil
or gas firing, depending on the jet burner that is
used. These burners must be according to the
EC Directives and prepared for the local supply
conditions and technical features of the boiler,
described in this manual.
Delivery
CPA-BTH boilers are delivered in three packages:
Package 1
Boiler body with the turbulators fitted in the
bank of tubes.
Inside the combustion chamber is the
insulating blanket for the boiler body, the door
clamps with backnuts and cleaning brush.
Package 2
Outer casing; inside the packing is a plastic
bag containing the screws for assembly, the
bands for fixing the insulating blanket and the
inspection window with gasket, the thermostat
pocket and the grommets.
In models with basic control panel (one or
two stage operation),the panel is delivered
with the casing package, including its fixing
screws.
Package 3
KSF digital control panel with models ordered
with this panel.
