Emptying the Ash Pan
Important: Be aware that embers in the ash can remain hot for up to 24 hours after the re in
the stove has gone out!
The ash pan is most easily emptied by pulling a waste bag over the pan, turning the pan upside
down, and then carefully pulling it up and out of the bag again.
Cleaning the Combustion Chamber
In order to extend the service lifetime of the wood-burning stove, it should be thoroughly servi-
ced once a year. First remove ash and soot from the combustion chamber. In Figure E you can
see which plates are found inside the combustion chamber. Carefully remove the vermiculite
plates, one after the other, in the following sequence:
1. Smoke deector (top plate)
2. Rear plate
3. Left corner plate
4. Right corner plate
5. Left side plate
6. Right side plate
After cleaning, the vermiculite plates are carefully reinserted in reverse order, starting with the
right side plate.
Over time, the combustion chamber’s effective yet porous insulation can become worn and
damaged. A crack in the back plate can cause secondary air to become incorrectly distributed
in the combustion chamber, and it should therefore be replaced. Cracks in the other plates will
not affect the efciency of the wood-burning stove. They should, however, be replaced when
worn down to half of their original thickness.
Automatics
The spring in the automatism should be controlled at least once every second year.
WIKING Miro 1-4 (Drawing G1): Lift the top plate off the stove. Remove the two screws (1)
in the top of both side plates. Open the door to the wood section and remove the screw (2) in
both sides (applies only to WIKING Miro 3-4). Remove both side plates. Remove the rear plate
of the stove. On a cold stove, the starting point of the feeler is controlled. The starting point
on a cold stove is about 10
0
above horizontal. It should feel easy going and bouncy when you
push it, no matter if the stove is cold or hot. Mount the rear plate, the side plates and the top
plate again.
WIKING Miro 5-6 (Drawing G2): Lift the top plate off the stove. Lift the front (1) of the heat
storage compartment up and forward, unhooking it from the four guide pins (2). Loosen the
two screws (4) at the top in all sides of the heat storage compartment. Remove the bottom
plate (3) in the heat storage compartment by lifting it up and forward. Remove the screw (5) in
both sides of the heat storage compartment. Open the door to the wood section and remove
the screw (6) in both sides. Remove both side plates. Remove the rear plate of the stove.
On a cold stove, the starting point of the feeler is controlled. The starting point on a cold stove
is about 10
0
above horizontal. It should feel easy going and bouncy when you push it, no matter
if the stove is cold or hot. Re-mount the rear plate, the side plates, the bottom plate in the heat
storage compartment, the front of the heat storage compartment and the top plate.
WIKING Miro 4/WIKING Miro 6 with soapstone cover (Drawing G3): Remove the rear plate
of the stove. On a cold stove, the starting point of the feeler is controlled. The starting point on
a cold stove is about 10
0
above horizontal. It should feel easy going and bouncy when you push
it, no matter if the stove is cold or hot. Remount the rear plate.
