The Nectre MK3 is fitted with two thick steel baffle
plates which help 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 may begin to sag a little due to the
excessive heat. This will not affect the way the fire burns,
however it is recommended that you turn the baffle
over to avoid continued sagging.
Eventually the baffle plate(s) will burn through (5+ years)
and if so will need to be replaced.
To remove the baffle plates:
1)
Lower baffle plate (500(w) x 300(d) x 12(h) mm) :-
raise the rear of the baffle plate, slide forward free
from the support lugs, and out through the door
opening.
2)
Upper baffle plate (400(w) x 160(d) x 5(h) mm) :-
slide baffle plate forward, free from the support
lugs and out through the door opening.
Repeat steps 1 to 2 in reverse to replace with the new baffle plates.
This task may be easier with the door removed from the
appliance and laid horizontally on a work-bench.
To replace the door glass:
1)
Two stainless steel strips hold the glass in place.
Remove the four M4 size Phillips head screws from the
stainless steel strips.
2)
Take out the glass, and check if the grey rope beneath
needs replacing. If so replace this rope as well.
3)
Position the new glass on top of the grey rope and re-
fit the stainless steel strips and M4 screws.
4)
Take extra care not to over-tighten the screws,
otherwise the glass will crack when the heater gets
hot and the door expands.
5)
On occasion, the M4 screws will have deteriorated
from the constant heat in the firebox resulting in them
snapping off when trying to loosen them. In this case, a
new hole can be drilled in the door and tapped using a
3.4mm drill bit, and M4 tap
This task may be easier with the door removed from the
appliance and laid horizontally on a work-bench.
1)
Remove any old seal from the door.
2)
Clean out the groove in the door that the seal was
bedded in using a flat-end screw driver or equivalent.
3)
Run a thin bead of clear roof and gutter silicone along
the groove.
4)
Starting at one end, press the new door seal rope into
the groove on the door.
5)
Refit the door if it has been removed and close.
If the door does not close firmly, then the door latch can be
adjusted.
In the front lower right-hand corner of the door opening,
inside the firebox, is a welded tab which the door latch
secures against when the door is closed. Using a large flat-
end screw driver, place it under the base of the tab and
gently lever it out.
Close the door with the door handle to test for any
improvement. If no improvement, repeat process until door
can be closed firmly.
