build-up on the fi re box window. Moreover, when moist wood
is burned, the resultant water vapour can condense in the fl ue
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 fi re hazard (chimney fi re). In addition,
if the wood has a high moisture content, the combustion
temperature decreases, which prevents complete combu-
stion of all the wood components and causes considerable
environmental pollution.
You can use a wood moisture meter to determine the residual
moisture content of your fi rewood.

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 fl ow 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 airfl ow.
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 fi lm may develop in some cases.
Do not use any detergents containing acid (e.g. citrus or
vinegar 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 fl oor/fl oorplate. Any
water that spills from kettles, boilers, or dishes should be
immediately mopped up.
Do not install the Tula 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 fi lm with the
original 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 fl ue 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 fl ue gas paths, open the fi re box and lift out the
upper heat-resisting slab and the vermiculite baffl e plates
located 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 baffl e plates (see Installation and
Maintenance Instructions).
NOTE!
Use a fl exible pipe brush to clean the fl ue pipe
at the cleaning port located on the fl ue 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
method 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 fi re box of your Tula stove are
made of Vermiculite. Vermiculite is a fi re-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 fi re box, located behind the slabs,
becomes visible. Tears or cracks in the heat-resisting slabs do
not impair the functioning of your stove.
