2 Product description
This boiler is a low temperature boiler for oil or gas
combustion with modulating boiler water temperature
control.
Your specialist heating company has equipped the
boiler with a suitable burner.
The boiler comprises:
–Control device
–Boiler casing
–Boiler block with thermal insulation
The control device monitors and controls all electrical
boiler components.
The boiler casing prevents energy losses and acts as
sound insulation.
The boiler block transfers the heat generated by the
burner to the heating water. The thermal insulation
prevents energy losses. Fig. 1 Boiler without burner

Operation of the heating system3
3 Operation of the heating system
3.1 Switching on the heating system
Before switching the system on, check
–that the operating pressure is high enough,
–that the fuel supply at the main shut-off valve is open
and
–that the heating system emergency stop switch is
switched on.
zSwitch the boiler water thermostat to "AUT"
(Automatic).
zSwitch the ON/OFF switch to ON (position "I"). This
switches on the entire heating system.
3.2 Switching off the heating system
zSwitch the ON/OFF switch on the control to OFF
(position "0"). This switches the boiler and all its
components OFF (for example the burner).
zClose the main fuel shut-off valve.
3.3 Emergency measures
In the event of an emergency, e. g. a fire, proceed as
follows:
zClose the main fuel shut-off valve.
zIsolate the heating system from the mains power
supply via the heating system emergency stop switch
or a corresponding domestic fuse.

PLEASE NOTE
Operating instructions, e. g. how to set the
temperature, can be found in the Îcontrol
unit documentation.
CAUTION!
SYSTEM DAMAGE
through frost.
The heating system can freeze up, if it has
been shut down.
zLeave the heating system switched ON
as long as possible.
zProtect your heating system against
freezing by draining the heating
system and DHW pipework at the
lowest possible point.

Operating instructions Logano G215 WS oil/gas-fired special boilers • Issue 02/2006
3.4 Check the operating pressure, if necessary top up with heating water and vent the
system
3.4.1 When should you check the operating
pressure?
Recently topped-up heating water loses much of its
volume in the first few days because it releases gases.
This causes air pockets, and the heating system will
start to rumble.
zAfter installing a new heating system, check the
operating pressure daily for the first few days. If
necessary top up with heating water and bleed the
radiators.
zAfter a while the operating pressure will only need to
be checked monthly. If necessary top up with heating
water and bleed the radiators.
3.4.2 Operating pressure, checking
The installer will have set the red needle on the pressure
gauge to the required operating pressure (at least 1 bar
pressure).
zCheck that the pressure gauge needle is within the
green range.
zTop up with heating water if the pressure gauge
needle is below the green range.
3.4.3 Filling the heating system and checking for
leaks
Before commissioning the heating system, check for
leaks to prevent problems during operation. Pressurise
the heating system to 1.3x permissible operating
pressure (observe the safety pressure of the safety
valve).
zShut off the pressure expansion vessel from the
system by closing the cap valve.
zCheck the connections and pipework for leaks.
zOpening the mixing and shut-off valves on the hot
water (primary) side.
zFill the system via an approved filling link.

over pressure during leak testing.
Pressure, control and safety equipment
may be damaged through excessive
pressure.
zWhen you carry out a leak test, make
sure that no pressure, control or safety
equipment is fitted which cannot be
isolated from the boiler water chamber.

3.4.4 Filling the heating system
Filling and refilling of the heating circuit must been
carried out by a method that has been approved by the
Water Regulation Advisory Scheme (WRAS), for the
type of heating appliances, i.e. Domestic (in-house)
Fluid Category 3. Non-Domestic (other than in-house)
Fluid Category 4. Depending on the Fluid Category the
approved method should comprise of the following:
1. Requirements Fluid Category 3 systems (fig see
below)
zControl valve (stop valve) including a double check
valve on the mains cold water supply pipe
zTemporary connection to e removed after filling
(filling loop)
zControl valve (stop valve) on the heating system
pipework
2. Requirements Fluid Category 4 systems (fig see
below)
zControl valve (stop valve) on the mains cold water
supply pipe
zStrainer
zVerifiable Backflow Prevention Device with reduced
pressure Zone(RPZ valve assembly) incorporating a
Type BA air gap
zTundish
zControl valve (stop valve) on the heating system
pipework
zShut off the pressure expansion vessel from the
system by closing the cap valve.
zSlowly fill the heating system. Observe the pressure
gauge whilst filling.
zClose the water tap and the boiler fill & drain valve
once the required operating pressure has been
reached.

3.5 Operating tips
Correct fuel
This heating system requires fuel of the correct type and
grade to ensure its proper operation.
Follow the advice of your installer if you want to convert
your heating system to another type of fuel or use fuel
with a different specification.
Location
3.6 Why is regular maintenance important?
Heating systems should be regularly maintained for the
following reasons:
–to achieve a high level of efficiency and to operate
the system economically (low fuel consumption),
–to achieve a high level of operational reliability,
–to maintain the highest level of environmentally
responsible combustion.
Use the following fuel only:
Company stamp/date/signature
CAUTION!
SYSTEM DAMAGE
through incorrect fuel.
zOnly use the fuel specified.
CAUTION!
BOILER DAMAGE
through contaminated drawn into the boiler
air.
zNever use chlorinated cleaning agents
or halogenated hydrocarbons (as, for
example, contained in spray cans,
solvents or cleaning agents, paints and
adhesives).
zAvoid very dusty atmospheres.
CAUTION!
SYSTEM DAMAGE
through a lack of, or unsatisfactory,
cleaning and maintenance.
zHave your system inspected, cleaned
and maintained annually by your
installer or a service engineer.
zWe recommend you enter into a
contract covering an annual inspection,
and maintenance as required.

Trouble shooting4
4 Trouble shooting
We differentiate between two types of faults
–Burner faults and
–Control unit and heating system faults.
A fault lamp on the burner illuminates if the burner
develops a fault. Generally, such faults can be reset by
pressing the reset button on the burner.
Control device and heating system faults are indicated
on the control device display, subject to the control
device being equipped with a display. For further
information see Îcontrol device documentation.
Correcting burner faults
zPress the burner reset button (Îburner
documentation).

CAUTION!
SYSTEM DAMAGE
through frost.
The heating system can freeze up, if it has
been switched OFF through a fault
shutdown.
zTry to remedy the fault.
zContact your installer immediately if
this is not possible.
