The levelling screw lock nuts should be
accessible below the shrouds. If necessary, loosen the
knurled screws securing the shrouds, raise the shrouds
and resecure them. To prevent scratching the hearth, fit
the two plastic caps (Supplied in the accessory pack)
over the heads of the levelling screws. See figure 13.

Place the fire centrally on the hearth making
sure that the spigot lines up with the spigot hole in the
closure plate. Gently slide the appliance into place. The
spigot must enter the closure plate to a depth of at least
25mm.

Level the fire by loosening the lock nuts and
turning the levelling screws in the feet up or down as
required while they bear on the hearth. When the fire is
level and square to the wall, retighten the lock nuts.
Loosen the knurled screws securing the feet shrouds and
lower the shrouds until they cover the levelling screws.

The position of the wall fixing holes in relation to the
closure plate spigot hole are shown in fig.14.

using the dimensions as shown in fig. 14. The positions
can alternatively be marked by placing the fire in
position and marking the wall through the upper holes
