stretch the seal when measuring. Remove the

8.2 The flue restrictor.
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 125mm flue liner is used. For flue
liners greater than 125mm and 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 flat with the appliance
and will require bending prior to fixing. Bend
