Convection Box Installation - Valor BR622 Installer's Manual

6.7 The appliance is supplied with two
fireback spacers extending backwards to
ensure sufficient clearance from the back
of the fireplace when installed without the
spacer kit 617K. If the appliance is being
installed with the spacer kit, reverse the
fireback spacers. This will give the
minimum rear clearance required when
used with the spacer kit (see figure 16).
If the kit is not used do not reverse the
fireback spacers. Never totally remove
the spacers.

This appliance is supplied with a flue
restrictor for use where the flue draught is
excessive. The restrictor must NOT be
fitted where a precast flue or a flue liner is
used. For all other installations the
restrictor should be fitted. There may
however, be certain exceptional
circumstances where fitting the restrictor
causes the fire to fail the spillage test. In
such cases the restrictor will have to be
removed. After removal conduct the
spillage check again.
The restrictor is packed loose with the
appliance and is fixed with three screws
(See figure 17).
