PREPARING WALL
Open the box with the backplate in it. Along with the backplate are the expansion
vessel, template and mountings.
Remove the template and fix it to the wall in the chosen location. Make sure it is the
right way up as the same template is used for left and right handed installations. The
template is marked WATER HEATER and BOILER; make sure the letters that are
written right side up show the two appliances as they are to be laid out. Mark the
centres of the two flues at the top of the template. The backplate bolt holes are in
pairs, top and bottom. Mark 3 holes on the top half of the template and 3 holes on
the bottom half of the template. In all cases mark the top hole of the pair.
Remove the template and drill the holes. If plugs (which are supplied) are required
the holes should be drilled with a 10 mm drill. Plug the holes and screw the supplied
screws in until they head is within 10mm of the wall. These will be tightened once
the back plate is put on the wall.
Drill the holes for the flues next. The flue terminals are 125mm diameter so the flue
holes must be larger than this. Do not drill them larger than 150mm.
