PREPARING BACKPLATE
When the backplate is removed from the box the 16L expansion vessel for the
heating circuit may not be fixed into position. Place a foam pad (supplied) on each
side of the expansion vessel to prevent any vibration noise. The vessel should be
installed to the back of the backplate through the bracket and held in with the spring
band. This is attached the same way regardless of left or right handed installation.
The flexible connection should be attached to the vessel and run through the open
hole in the middle upright of the frame. This places the other end of the flexible
connection on the boiler side of the backplate.
Next determine the top of the backplate. The water heater mounts on the panel in
front of the expansion vessel. Stand the panel up so that the water heater will be on
the desired side of the backplate right side up. Near the bottom of the backplate on
the water heater side there is a 20mm blanking gland. Remove the blanking gland
and put the water heater cabling and gland through and tighten down the gland.
The backplate is supplied prewired for ease of installation. However, the external
controls will have to be connected to the controls box. Before hanging the backplate
locate the two off Din plug connection points on the outside of the box.
