5.6. Keep the original packaging for 2 years and then recycle.
5.7. Due to the requirements of the EN303-5 standard, it is recommended mounting double wall piping for the
entire VAP range. This is also mandatory by the pipe manufacturer's directive if we go through the beams or
install gas outlet pipes outside the house. This is because the exhaust working temperatures of the aforesaid
range are between 80 and 150°C. The assembly of this pipe is to avoid condensation and excess dirt on it.
Mandatory: It will be made of a material resistant to the aggressive action of the combustion products, to
condensation and to constant temperatures of 300 °C. The material of the chimney will comply with the local
legislation for its application.
5.8. In cases of humidity in the atmosphere above 60% is highly recommended installing a double-walled pipe of
stainless steel.
5.9. If the boiler is installed in a wooden house, the vertical pipe MUST be installed using double-wall insulation
and special attention should be paid to the area where it goes through the wall, isolated sockets are
mandatory.
5.10. If the boiler is going to be mounted in a French-style fireplace, use a flexible tube of stainless steel for the gas
outlet, fexible braided hoses for the hydraulic conections and a cover plate to avoid the gas reverse.
5.11. Seal the gas out pipe's joints with aluminium belt and silicone of high temperature (300 °C) and fix the pipe
with clamps so that it cannot be removed without tools nor move the heater / boiler.
5.12. Gas output must be located in a ventilated area, not in closed or half-closed areas e.g. garage, corridor, air
space of the house or places where gas may concentrate.
5.13. The external parts of the boiler may reach high temperatures that might burn when touching; it is
recommended to use a non flammable grid to avoid risk of burn for children and old people.
The end of the gas outlet flex should remain higher than the boiler's output. It is mandatory to install at
least two metres in length vertically to create natural current preventing smoke, odors or eventual cut of
electric supply.
The horizontal pipe must not be longer than 1 metre; greater lengths mean ash, condensation or corrosion
may build up in this area.
Faced with cut of electric supplies and unusual weather conditions (storms, strong winds) it is
recommendable to install an uninterruptible power supply (UPS) which we have available as an option. This
apparatus only feeds the exhaust vent.
5.14. Distances from doors, windows, ventilation grids or air input to the house or building:
