Maximum Amount Of Wood; Controlling Combustion Air - Dovre ROCK 350 Installation Et Mode D'emploi

Maximum amount of wood

To stoke continuously at the rated power, wood must
be added every 45 minutes. If you use a smaller
amount of wood each time, you can add wood more
often. Each stove is designed to work with a specific
maximum amount of wood. If you use a larger quantity
of wood, the heat output increases. This can cause
the hearth to be overloaded and parts can be dam-
aged.
Allowable maximum amount of fuel when using wood
with a moisture content of 15%:
ROCK 7 KW can be filled with a maximum of
l
1.5 kg wood every 45 minutes.
ROCK 9 KW can be filled with a maximum of
l
1.5 kg wood every 45 minutes.
Do not fill the combustion chamber more that one third
full, and never stack wood above the openings for sec-
ondary air.

Controlling combustion air

The appliance has one air slide that regulates both the
primary air and the secondary air inlet. If the air slide is
in position C, the primary and the secondary air inlets
are open. As the air slide is further closed, the primary
air inlet and then the secondary air inlet is closed. If
the air slide is completely closed in position A, a small
air vent remains open to allow for post-combustion
under the baffle plate.

The secondary air inlet regulates the air for the glass
(air wash) (2).
The back wall has permanent vents (3) below the
baffle plate that allow for post-combustion.

Advice
Never burn wood with an open door.
Regularly burn wood with intense roaring fires.
If you burn at a low setting frequently, tar and
creosote may be deposited in the flue. Tar and
creosote are highly combustible substances.
Thicker layers of these substances may catch
fire if the temperature in the flue increases
suddenly. By allowing the fire to burn very
intensely regularly, layers of tar and creosote
will disappear.
Low intensity fires can also cause tar deposits
on the stove window and door.
When the outside temperature is mild, it is
better to burn wood intensely for a few hours
instead of having a low intensity fire for a long
period of time.
Control the air supply using the air vent.
The air inlet not only supplies air to the fire but
to the glass as well, so that it does not quickly
become dirty.
Open the primary air inlet for the time being if the air
supply by the secondary air inlet is inadequate or if
you want to fan the fire.
Topping up with a few logs regularly is better than
adding many logs in one go.
