Multi Pass Oil Boilers
Kitchen models for short periods - Set the On/Off to
OFF.
To restart, simply set the switch to ON.
Kitchen models for long periods: Set the On/Off
switch to OFF and switch off the electricity supply to
the boiler. If required, the fuel supply valve may be
closed and the water and electricity supplies turned off
at the mains.
To restart, refer to the full lighting instructions above.
Boiler House models for short periods - Switch off
the electricity supply to the boiler.
To restart, switch on the electricity supply to the boiler.
Boiler House models for long periods - Switch off
the electricity supply to the boiler. If required the fuel
supply valve may be closed and the water and
electricity supplies turned off at the mains.
To restart, refer to the full lighting instructions given
in Section 1.3.
1 Check that the boiler On/Off switch is ON.
2 Check that the programmer (if fitted) is working
and is in an 'on' period.
3 Check that all thermostats are set to the desired
setting and are calling for heat.
4 Check if the burner 'Lock-out' reset button is lit. If it
is, press it to start the burner. If the burner fails to light
and goes to 'Lock-out' again, check that you have
sufficient fuel in the storage tank and that the fuel
supply valve is open.
5 Ensure that a fuse has not blown or that the
electricity supply has not failed.
6 Check to see if the safety thermostat has operated
(see Section 1.7).
If the burner still fails to light after carrying out these
checks then a fault exists. Switch off the electricity
supply to the boiler and contact your Service engineer.
Multi Pass boilers will operate on either Class C2 Kerosene
or Class D Gas Oil to BS 2869:1998. Your Installer will
have informed you of the type of fuel your boiler has been
set to use and he will have marked this on the boiler data
label. You should always quote the type of fuel you
require when ordering from your supplier.
Note: Balanced flue models (flue terminal through
the wall) must only be used with Kerosene, unless the
flue terminal is more than 2.0 m above ground level.
Do not wait until the fuel runs out before you order
some more. Sludge in the bottom of the tank may be
drawn into the fuel lines. If it is possible, switch off the
boiler when the new supply is delivered and leave the
fuel to settle for an hour before restarting the boiler.
1 Boiler thermostat - This control allows the
temperature of the water leaving the boiler to heat
the radiators and domestic hot water to be adjusted.
Note: If you have a cylinder thermostat on your hot
water cylinder, this will control the temperature of
your domestic hot water. The boiler thermostat
setting must be equal to or above the cylinder
thermostat setting to enable the cylinder thermostat
to control the domestic hot water system.
The boiler thermostat has an operating range of 65
to 85°C. The following settings are recommended:-
a
Heating and hot water in Winter 85°C
b Hot water only in Summer 65°C
2 Burner Lock-out reset button - If there is a
burner malfunction, a built-in safety circuit
switches the burner off and the Lock-out reset
button will light. Usually such malfunctions are
short lived and pressing the reset button will
restore normal operation.
If the burner continually goes to 'Lock-out' a fault
exists or the fuel supply is low. If you have sufficient
fuel, you will need to call your Service engineer.
3 Safety thermostat - Your boiler is fitted with a
safety overheat thermostat which will automatically
switch off the boiler in the case of a control
malfunction causing overheating.
If your boiler goes off and you try to light it but
nothing happens and the 'Lock-out' reset button on
the burner is not lit, the overheat thermostat has
probably operated. The boiler will not light until
the thermostat is reset. To reset, unscrew the small
plastic cap (see Fig. 23 or 24), press the button
then replace the cap.
If this condition continually repeats, contact your
Service engineer.
4 Programmer (if fitted) - Refer to the instructions
supplied with the Programmer.
