5.1 Installation Tula direct vent stove

The door of the Tula direct vent stove is self-locking. To ensure
that the self-locking mechanism functions perfectly, use the
spirit level to precisely align the Tula in a horizontal position.
The stove can be aligned by means of four levelling feet (see
Assembly and Maintenance Instructions).
Please make sure that there is suffi cient ventilation in the
room where the Tula will be installed. For rooms with a cubic
volume of more than 50 m³, an hourly air exchange ratio of
1.5 is required. With smaller rooms, the air change rate needs
to be higher
CAUTION!
The negative pressure in the room where the
stove is installed is not permitted to exceed the
value of 8 Pascal (the ventilation system desi-
gner specifi es the air pressure in Pascal units).
We recommend setting the ventilation system
to a maximum negative pressure of 4 Pascal.
CAUTION!
Simultaneous operation of the stove and
exhaust hoods can cause negative pressure
above the permitted value of 8 Pa to build up
in the room where the stove is installed, which
can lead to problems such as fl ue gas escaping
from the stove.
NOTE!
To ensure that air is not drawn out of the room
where the stove is installed, we recommend
using a window contact switch to lock exhaust
hoods that guide the air to the outside.

6. The Chimney Tula Standard
The Tula Standard has to be connected to a suitable chimney
with a minimum effective chimney height of 4.50 m. It can be
connected to a chimney to which other fi replaces are already
connected. The chimney cross section should correspond to
the fl ue pipe cross section. If the effective chimney height is
too low and/or the chimney cross section is too large or too
small, the draught capability of your stove can be impaired.
The Tula Standard requires a 13 Pa output pressure (chimney
draft). At higher output pressures, the stove emissions
increase, which puts a high load on the stove and can lead to
damage. The Tula Standard stove has a maximum permissible
output pressure of 35 Pa. To limit the output pressure, a
butterfl y valve (fi g. 4) or output pressure limiter can be used.
6.1 The Chimney Tula direct vent stove
The Tula direct vent stove needs its own separate chimney.
The draught capability of your stove can be impaired by a
chimney cross section that is too large or too small and/or an
effective chimney height of less than 5.5 m. The „effective
chimney height" is the distance between the fl ue gas intake in
the chimney and the top of the chimney pot. After a soot fi re
in the chimney, the impermeability (air-tightness) of the fl ue
gas paths has to be checked.
We recommend connection to a multi-leaf chimney with a
cross-section having a maximum diameter of 150 mm and a
minimum „effective chimney height" of 5.5 m.
If these specifi cations cannot be met, we advise you to
check the suitability of the chimney by means of a chimney
calculation..

Flue Pipe Connection

CAUTION!
The fl ue pipe must be well sealed at the
chimney entrance and cannot project into the
inner cavity of the chimney; otherwise the fl ue
venting will be impaired (fi g. 3).

7.1 Flue Pipe Connection Tula Standard

The Tula Standard has to be connected to the chimney with a
fl ue pipe with an inside diameter of 15 cm. Please ensure that
all pipe pieces are tightly fi t at the connection junctions. We
recommend using elbow pipes with cleaning hatches.

7.2 Flue Pipe Connection Tula direct vent stove

The Tula direct vent stove has to be connected to the chimney
with a fl ue pipe having an inside diameter of 15 cm. The fl ue
pipe has to be sealed at the fl ue pipe connection piece with
Hase Sealing Paste. The fl ue pipe connection to the chimney
has to be gas proof and sealed with a suitable sealing cord
and heat-resistant silicone (see Fig. 12).
