4.27. When fitting stoves in brickwork chimneys a perfect seal between the flexible and the rigid pipe must be
achieved. Similarly, the insulation to be placed at the contact areas between the pipe and possibly
inflammable zones must be taken into account. The tube end may be left inside the chimney itself, taking
into account its opening.
Once installation is complete, we must seal the chimney from the inside of the house.
Stainless steel hose clamp.
T of 90° with outlet.
Wooden ground.
Non flammable floor protection.
Isolated stainless steel flexible tube.
Rigid flexible pole adapter.
Minimum 200mm.
It must exceed roof height by 1 metre.
If the tube over 8 m in length, the next larger
size will be used.
4.28. Installing a fitted stove in a brickwork chimney can be done using flexible piping in its entirety, as indicated in
drawing 11. We must take special care when sealing the chimney and gas venting to avoid gas blowing back
during storms.
Stainless steel hose clamp.
T of 90° with outlet.
Wooden ground.
Non flammable floor protection.
Stainless steel flexible tube.
Rigid flexible pole adapter.
Anti blow-back seal.
Minimum 200mm.
It must exceed roof height by 1 metre.
If the tube over 8 m in length, the next larger
size will be used.
When installing a flexible tube for gas outlet, be careful that this is not in contact or close to the circuit board
or combustible material.
Reduction of the air intake pipe section and gas output section is strictly forbidden.
Ignore section 4.22 in case of airtight installation.
It must be installed in a room with positive atmospheric pressure (minimum 5 pascals). Never make it
work in depression (airtight rooms or without the due air renovations).
