INSTALLATION - Page 13
Initial Preparation
Remove the outer carton and locate the fitting kit. Remove
and discard the packing pieces and unpack the boiler hood.
The hood may be fitted now or when the boiler is in situ. Use
the four nuts and set screws provided.
Remove the controls heat shield from its retaining clips.
Remove the four screws retaining the combustion box door
and remove the door.
Slacken the two screws holding the controls to the boiler
base. Remove the two screws retaining the controls to the
combustion box and remove the controls.
The boiler as supplied has the flow and return water
connections at the left hand side of the appliance.
For installations requiring the water connections at the
right hand side proceed as follows:
(This operation is performed most easily with the boiler on its
back).
Lift out the 3 heat exchanger baffles, noting their orientation.
Lift the heat exchanger from the appliance and remove the
side blanking plate.
Transfer the 3 sealing rings from the holes in the left hand
side of the boiler to those in the right.
Rotate the heat exchanger to place the water connections at
the right hand side, return the
heat exchanger to the combustion box.
DO NOT TURN THE HEAT EXCHANGER UPSIDE DOWN
NOTE: The heat exchanger is correctly oriented when the
three water connections line up with the holes in the right
hand side of the combustion box and the thermostat pocket
aligns with the corresponding hole in the door. The unfinned
heat exchanger water tubes face the burner.
Remove the blanking disc from the left hand hole in the
boiler door and the rubber seal from the right hand hole and
swap them over.
Replace the heat exchanger baffles and blanking plate.
