8. PREPARING APPLIANCE FOR INSTALLATION
1.
Detach the burner unit from the hotbox
by removing two screws (See figure 12).
Lift the burner unit clear.
2.
Fit the two “U” section seals to the
bottom edges of the hotbox side flanges
(See figure 13).
3.
It is important that the grommet
supplied in the loose parts pack is fitted
to the hole in the rear of the hotbox.
4.
For concealed connection only: Pierce
the grommet to allow the pipe to pass
through it. The grommet should envelop
the pipe. If the hole is larger than the pipe, seal it with tape.
Do not pierce the grommet unless the supply pipe is to
pass through it
.
5.
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 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 two screws (See figure 14).
