5.1 Side Vent Grille
One side vent grille is supplied with the boiler and can be fitted
at the rear of the left or right hand side casing. The grille is fitted
on the opposite side to any pipework connections.
If required, fit the grille, using plastic pegs at the top and bottom,
see diagram 5.1, prior to fixing the side casing. The plastic pegs
are a tight fit, so they are best pushed home with a flat faced tool.
Discard the grille if water connections are made on both sides
of the boiler or if the boiler is screened by fixtures.
5.2 Side Casings
Fit each side casing by locating the lugs into the appropriate
slots in the boiler plinth, see diagram 5.2, depending on the
required casing height, see diagram 1.2.
Secure the side casings to the casing brackets at the front and
top.
