Chimney:
There must always be a chimney stack with a diameter of at least 15 cm. This is equivalent to
clearing of 175 cm
2
. Remember to ensure that the
draught conditions
are satisfactory and
that smoke does not inconvenience your neighbours.
If your chimney has a regulating damper, the draught can be regulated. Please note that the
damper must never be completely closed. There must always be at least 20 cm² of free passage
through the chimney.
In some cases, it can be an advantage on days when the wind is blowing strongly.
At nominal operation, the stove has been tested with a flue gas flow of 4.6 g/s and with flue gas
temperature of 265°C at a room temperature of 25°C.
Varde stoves are always equipped with a smoke guide plate. This ensures that the smoke
’
s path
to the chimney is as long as possible. This ensures that the smoke
’
s heat is released in your
home rather than in the open air outside. The smoke guide plate lies loosely in the stove
’
s
combustion chamber and you must ensure that the plate is pushed all the way back against the
combustion chamber
’
s rear plate.
New chimney
If you shall install a new chimney, it is recommended to consult your local chimneysweeper, as
there can be specific local circumstances that can have influence on the height or routing of the
chimney. You can find inspiration, and common guideline on www.vardeovne.dk
Is my existing chimney good enough?
The chimney is the motor of the stove, the chimney is driven by heat, so it is important that you
have a well function chimney in order for the stove to work properly.
A modern wood burning stove puts up higher demands for the chimney than older stoves. A
modern stove burns both cleaner and more efficient than older stoves, the higher efficient will
give more heat in your living room for the same amount of firewood. The higher efficiency of a
modern stove also have that effect, that there are used less heat to generate draft your chim-
ney.
It can be a possibility that your old chimney will not be able to build up a sufficient draft to run a
modern clean burning stove, be course of the lesser heat lead into to the chimney.
This may occur with shorter or older brick chimneys, especially without an insulating core.
It is very rare that a steel chimney or modern insulated brick chimney not will be sufficient.
Typical effects of insufficient draft, smoke come out when door is opened and soot on the glass.
If you have a chimney with draft problems, a draft booster could be a solution.
It is recommended that you consult with your local chimneysweeper for more specific advice.
Marking of condensate drain.
A condensate drain has
now been made.
Make an opening using chisel
or similar.
Condensation drain in the flue collar
Your stove is fitted with a cast iron flue collar from Varde Ovne. The flue collar is designed for a
flue pipe (chimney) with an inner diameter of 150 mm.
You can establish a condensate drain yourself, if your steel chimney is to be fitted in the stove
’
s
top outlet:
Make a hole in the bottom of the exterior grate (at the mark) using a small chisel or similar,
thus making the condensate drain yourself, if you need it.
