31 Multi Pass Oil Boilers
If the optional plug-in electronic programmer is not
fitted, it is recommended that the boiler should be
connected to a switched mains power supply from an
external timer or control system. Refer to Section 8 for
a typical control system wiring diagrams.
1 Lift off the boiler case top panel, if it has not
already been removed.
2 Carefully uncoil the two thermostat capillaries and
fit the two thermostat phials into the pocket
previously fitted on either the left or right
connection on top of the boiler. Ensure that the
phials are fully inserted and take care not to
damage or kink the capillaries.
3 Remove the wiring cover and open the cable
clamp. Route the supply cable through the hole in
the rear panel (using the grommet supplied) up to
the control panel, pass it through the cable clamp
and connect to the boiler terminal block (refer to
Fig. 35 or 36) as follows:-
Brown to mains live (terminal 1)
Blue to mains neutral (terminal 2)
Green/Yellow to mains earth (terminal 4)
If the plug-in programmer is not fitted, ensure that the
RED wire link, between terminals 1 and 9 on the 12-
way boiler terminal block is fitted, (not 140/160 or
160/200).
Note: Ensure that the route and length of the cable
is such that the boiler front cover plate can be
easily removed without disconnecting the supply
cable from the terminal block.
4 If the optional plug-in electronic programmer is to
be fitted, follow the fitting instructions given in
Section 4.8 at this point.
5 Secure the cable in the cable clamp.
6 Place the wiring cover in position over the terminal
block, taking care not to trap any wires and secure
in position with the two M4 screws provided.
7 Ensure that all external wiring is adequately
supported.
Do not switch on the electricity supply at this stage.
4 - BOILER INSTALLATION
Note: Not applicable to 140/160 or 160/200 models.
Important: Ensure the electrical supply to the boiler
has been isolated before fitting the programmer.
Remove the screws holding the back of the control
panel in place and move it back enough to allow
access to the rear of the timer aperture.
1 From underneath the control panel, remove the
screw securing the bracket behind the timer
aperture. Withdraw and discard the bracket.
2 Remove the blanking piece from the timer aperture,
in the control panel fascia, by firmly pressing on
the Grant logo (in the centre of the black square)
until it is detached from the rear of the fascia.
Remove the blanking piece from the panel and
discard.
3 Check that the wiring harness supplied with the
programmer is correctly connected to it as
follows:-
Brown wire to Mains Line (L) terminal of
programmer
Blue wire to Mains Neutral (N) terminal of
programmer
Red wire to Heating On terminal of programmer
Brown wire to Water On terminal of programmer
Yellow wire to Water Off terminal of programmer
4 Connect the programmer to the boiler wiring by
connecting the 6-way plug and socket, ensure the
plug is pushed firmly into the socket.
5 Carefully fit the programmer into the aperture and
gently push fully home.
6 Connect the control system wiring to the 12-way
boiler terminal block. Refer to Section 8 for details
of typical system control wiring diagrams.
Important: Disconnect and remove the RED wire
link between terminals 1 and 9 on the 12-way
boiler terminal block.
7 Replace the back of control panel and complete the
electrical connection procedure from paragraph 2
of Section 4.7.
Refer to the User's Operating manual provided with
the boiler for the operation and setting of the
programmer.
