build-up on the fire box window. Moreover, when moist wood
is burned, the resultant water vapour can condense in the flue
pipe or chimney, which can lead to a build up of shiny soot
on the chimney or chimney creosote. Chimney creosote can
cause unpleasant odours and damage brick chimneys, while
shiny soot poses a fire hazard (chimney fire). In addition, if
the wood has a high moisture content, the combustion tem-
perature decreases, which prevents complete combustion of
all the wood components and causes considerable environ-
mental pollution.
You can use a wood moisture meter to determine the residual
moisture content of your firewood.

23. Storing and Drying Wood

Wood needs time to dry. If stored properly, it will air-dry in
approx. 2 to 3 years.
Saw, split, and store the wood ready for use; this ensures rapid
drying because smaller pieces of wood dry better than larger,
uncut logs.
Stack and store your wood logs in a ventilated location that is
as sunny as possible, ideally facing south, and ensure that the
wood is protected from rain.
Leave a hand's width between the individual piles of wood so
that air can flow between them and carry away any escaping
moisture..
Do not cover your wood stacks with plastic sheeting or tarpau-
lins; otherwise the moisture cannot escape.
Do not stack fresh wood in a cellar or basement, since it will rot
rather than dry due to the lack of airflow.
Only store already dried wood in dry and well-ventilated cellar
or basement rooms.

24. Cleaning and Maintenance

24.1 Steel Cladding

Hase stoves are coated with a heat-resistant open pore lacquer
that provides only limited corrosion protection; accordingly, a
rust film may develop in some cases.
Do not use any detergents containing acid (e.g. citrus or vi-
negar cleaners) to clean the steel parts. The steel parts can
be adequately cleaned by wiping them down with a slightly
moistened cloth.
Avoid using excessive water to clean the floor/floorplate. Any
water that spills from kettles, boilers, or dishes should be im-
mediately mopped up.
Do not install the Luno in „damp rooms", e.g. conservatories
or winter gardens. Do not temporarily store the stove in an
unheated building shell or garage.
NOTE!
Treat areas covered in a rust film with the ori-
ginal Hase Stove Lacquer Spray. Be sure and
follow the instructions on the spray can. Your
authorised Hase dealer carries the stove lacquer
spray and can give you tips on using it.

24.2 Flue Gas Paths

The stove and flue pipes should be inspected for sediment and
deposits at the end of each year's heating period (even more
often if required, e.g. after the chimney has been cleaned),
and then cleaned if necessary.
To clean the flue gas paths, open the fire box and lift out the
upper heat-resisting slab and the vermiculite baffle plates lo-
cated on top of it. Any soot or dust sediment/deposits can
be brushed off and vacuumed away. Then re-insert the heat-
resisting slab and the baffle plates (see Installation and Main-
tenance Instructions).
NOTE!
Use a flexible pipe brush to clean the flue pipe
at the cleaning port located on the flue pipe.

24.3 Ceramic Glass Panels and Windows

When the stove is properly operated, the secondary air forms
an air curtain at the pane, which minimises the formation of
soot on the glass.
If ash particles get on the ceramic glass panels, we recom-
mend a tried and true environmentally-friendly cleaning me-
thod as an alternative to conventional glass cleaners:
Ball some up paper towels or newspaper, moisten the ball, dip
it into the cold wood ash, rub the panel with it and then wipe
the glass with a clean, dry ball of paper.

24.4 Fire Box Lining

The heat-resisting slabs in the fire box of your Luno stove are
made of Vermiculite. Vermiculite is a fire-resistant mineralogi-
cal granulate material with excellent insulating properties. The
density of the slabs arises from the optimal balance between
mechanical stability and insulation properties. The relatively
soft surface is subject to natural wear and tear, depending on
use. The heat-resisting slabs have to be replaced if parts break
off and the back wall of the fire box, located behind the slabs,
becomes visible. Tears or cracks in the heat-resisting slabs do
not impair the functioning of your stove.
