Rules: TS 7363 common
The Aksa Kayserigaz Kayseri specification
Aksa's Indoor Installation Design and Application Rules (2019 Rev.01) have been read. The document leaves the calculation values to the TS 7363:2018 standard, and since the text of the standard has not been read, the calculation limits use a common profile, based on TS 7363 general rules. This page and the values in the app will be updated when the standard is uploaded.
Rules from the Aksa document built into the app
- DN15 is not used in welded installations inside a flat (art. 2.10); automatic sizing picks DN20 or larger.
- No tee branch is made at the meter outlet just before the pipe enters the flat (art. 2.9).
- Inlet valves are of the lockable type and unused outlets are sealed and blanked (art. 2.7); the main shut-off valve and the meter valve carry an OPEN-CLOSED sign (art. 2.5).
- Type C or condensing appliances up to 50 kW may be placed outdoors in a ventilated cabinet (art. 2.15).
Values of the common profile
