6.3 Underfloor heating system (plastic pipes)
When connecting or using an underfloor heating system, designed with plastic pipes, or
plastic pipes are used elsewhere in the installation,one should ensure that the plastic
pipes used comply with the DIN 4726/4729 standard. It is set out in this standard that
the pipes may not have oxygen permeability higher than 0.1 g/m³.d at 40°C. If the system
does not comply with this DIN standard, the underfloor heating component will have to
be separated from the central heating appliance by means of a plate exchanger.
No recourse can be made to the terms of the warranty in the event of failure
to observe the regulations pertaining to plastic underfloor heating pipes.
6.4 Gas connection
The appliance pipe is fitted with an internal thread, into which the tail piece of the gas tap
can be screwed.
United Kingdom:
The gas supply must comply to the current Gas Safety, Installation & Use Regulations.
Ireland:
- Irish standard 813
- Domestic gas installations
The connection to the appliance must include a suitable method of disconnection and a
gas control cock must be installed adjacent to the appliance for isolation purposes. The
nominal inlet working gas pressure measured at the appliance should be 20 mbar for Nat
gas (G20).
Make sure that the gas pipe work does not contain dirt, particularly with new
pipes.
When the boiler has to be converted from natural gas to LPG, ATAG provides special
kits for this purpose. Special instructions are supplied with the kit.
Always check the installation of all of the parts through which gas flows
(using leak-search spray)
