Plumbing Gas Geyser

600kpa maximum water pressure to be supplied to unit
Recommended 3⁄4” water piping. n.b. – 1⁄2” is sufficient where good water pressure is supplied (Advance Geyser).
1/2" water piping (Standard Geyser).
It is recommended that a non-Return valve be installed on the hot water outlet of the unit.
A water shut-off valve must be installed on the cold water inlet, recommended use of conex fittings onto unit.
For solar-boost systems, water of not more than 75 degrees C should enter the unit, no controllers to be connected (Advance geyser).
All filters, including tap filters should be cleaned regularly for optimal performance. An in-line strainer should be fitted

to the cold water supply pipe.

Cold water supply should be as direct from source as possible and balanced pressure where able. This is to eliminate supply pressure reduction on the units when using other non-hot water outlets.
Location for the gas unit must be installed centrally, or as close as possible to the point of maximum hot water demand
