MAINTENANCE AND SERVICING
2.1.
REPLACING THE FIRE BRICKS
The firebox needs fire bricks to increase the thermal mass and
guarantee the longevity of the steel firebox. Over time the
firebricks may become cracked and crumble away. At this
point they should be replaced.
To replace the firebricks:
1)
Remove the firebox side shields.
2)
Remove the brick retainer.
3)
Remove bricks and ash from the fire box.
4)
Replace with new bricks and reposition the brick retainer
over the bricks.
5)
Refit the side shields.
2.2.
REPLACING THE FIREBOX SIDE SHIELDS
The heater comes with two 8mm 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 cutout
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.
2.3.
REPLACING THE BAFFLE PLATE
The baffle plate helps to retain the heat in the firebox by
lengthening the path of the flame before it goes up the flue.
Over time, the baffle plate will begin to sag a little due to the
excessive heat. This will not affect the way the fire burns.
Eventually the baffle plate will burn through (5+ years) and
must be replaced.
To remove the baffle plate:
1)
Slide the baffle plate forward until the rear edge is clear
of the brick retainer.
2)
Lowering the rear of the baffle will allow the front to slide
past the front support pins.
3)
Once the baffle has cleared the front support pins, it can
be removed from the firebox.
4)
Repeat steps 1) to 3) in reverse to fit the new baffle plate.
2.4.
ADJUSTING THE DOOR
If the door does not close firmly, the latch can be adjusted.
The latch is fastened onto the door with two removable
washers. Use a socket wrench to undo the M12 nut, then
remove one of the washers directly beneath the nut. Securely
fasten latch assembly again.
Close the door with the door handle to test for any
improvement. If no improvement, remove second washer.
2.5.
CHECK CREOSOTE BUILD UP
Over time creosote and ash can build up in the bottom of the
heater. If not checked and cleaned annually it can result in a
blockage stopping the flames and smoke from exiting up the
flue when the by-pass damper is closed.
The plate in the bottom of the oven can be lifted from the
front where there is a raised edge. With a dust pan brush, go
through the square access hole and brush along the sides and
rear of the heater bringing any creosote build-up into the
centre so can be removed with the dust pan.
