1. REPLACEMENT OF BAFFLE PLATE
The 6mm thick steel baffle plate helps to retain the heat in
the firebox by lengthening the path of the flame as well as
protect the top plate of the heater.
Over time, the baffle will begin to sag a little due to the
excessive heat. This will not affect the way the fire burns.
Eventually the baffle will burn through (5+ years) and if so
will need to be replaced.
To remove the baffle:
i) Lift the baffle plate and slide forward until the rear
edge is clear of the brick retainer.
ii) Lower the rear of the baffle plate until the front edge
of the baffle plate has cleared the support lugs.
iii) With the baffle plate clear of the brick retainer and
support lugs, it can be removed through the door
opening.
iv) Repeat steps i) to iii) in reverse to replace with the
new baffle.
Note: 100mm strip welded to baffle plate faces down and
locates between the two support lugs.
2. Replacement of firebox side shields
The heater comes with two 8 mm thick sacrificial shields
fitted to the sides of the firebox to protect the walls of the
firebox.
Lugs on the shields allow them to hang over the angled cut-
out on the sides of the firebox along the top.
To remove the shields, raise until the support hooks are clear
of the triangular cut-out on the side of the heater and
remove.
To fit new side shields, simply hang them on the diagonal
edge of the triangular cut-out on each side of the firebox.
The side shields come as a left and a right, they are not
interchangeable.
