Correct Indoor Installation
If flexible hose is being used, it MUST be BS3212 of SANS1156 approved hose. The hose MUST
NOT be longer than 2 meters. The hose should NOT be fed directly through a wall or
cupboard, neither should it be behind or above the gas water heater.
We DO NOT recommend using hose for the gas connection. This will restrict the gas flow and
volume and will underperform, as a result. We recommend to use copper, composite stainless-
steel flex pipe.
