Q-FLEX VELTANIUM GUIDELINES
HOT WATER APPLICATION
■ Short pipe length after connection to water meter before going in ground. ■ Connection to an externally located water heater for the above exceptions, the following must be ensured. ■ The length of pipe installed above ground shall be kept to an absolute minimum not exceeding 2 metres. Below ground installation should always be preferred. ■ All pipe and connections must be adequately protected from corrosion, frost and excessive temperature. ■ The system components must be protected from any mechanical and physical damages. Consideration shall be given to the type and level of damage which is likely to occur during the long term operation of the system, e.g. UV-radiation, etc.
CORROSION PROTECTION
All joints in ground, except for Veltanium Plus brass fitting joints with Veltanium Plus PEX-A pipes, must be protected against corrosion using a recognized corrosion-protec tion system, such as the petrolatum system or equivalent. When using an alternative Corrosion Protection System. ■ Ensure chemical compatibility with Veltanium Plus pipes and fittings. outer PE-layer to the aluminium layer. ■ Only use systems which are suitable for the application and ground conditions and include an approved cavity filler/putty that can be applied to profile the joint, allowing smooth application. When using Veltanium Plus pipe ensure there is no adverse e ect on the adhesion of the The corrosion protection system shall cover a minimum of 150 mm of the pipe on each side of the joint. Ensure mechanical protection is provided to avoid any damage to the corrosion protection tape e.g. by backfill material. The Building Codes of Australia and New Zealand both stipulate that service penetrations must not reduce the fire resistance level/rating of the building element they penetrate. In Australia, the verification requirements for service penetrations are specified in the National Construction Code (NCC) Vol. 1 under Specification
