Please refer to the installation instructions
supplied with the plume management kits.
1. The terminal must not cause an obstruction nor the discharge a

pluming of the flue gases and any increase in noise levels.
If plume redirection is utilised, the
clearance from any opening must
be increased in the direction of
the plume to 1,500mm.
2. If a terminal is fitted less than 2 metres above a surface to which
people have access, then a guard must be fitted. The terminal guard

Showers
*Subject to conditions.
When a loose head shower with a flexible hose is used over
a bath or shower tray, the hose must be fixed so that the
head cannot fall closer than 25mm (1in) above the top edge
of the spill over level of the relevant bath or shower tray.
Alternatively, the feed pipes to the shower should
incorporate a double check valve assembly or a check valve
and vacuum breaker.
With fixed head showers no provision is necessary.
The use of a thermostatically controlled shower will give
added comfort and safeguard against high hot water
temperatures.
Bidet
The supply of hot and cold water mains direct to a bidet
is permitted provided that the bidet is of the overrim
water feed type. The outlet(s) should be shrouded and
not have any temporary hand held spray attached. No
other anti-syphonage arrangements are necessary.
