CONNECTIONS - PLUMBING
All Plumbing Connections should be made in accordance with appropriate
Local Authority Regulations.
Flush out pipes before connecting unit to ensure that no foreign matter blocks
the valve seating.
Use Line strainers where required by Local Authority.
It is recommended that Connections should be made with compression fittings
– under no circumstances should any connections in the installation be welded,
brazed or soldered. Provided flare annealing and the use of hammer type
flaring tools are not used, crox or flare connections may be used.

PRIzE SIzES
For best results, choose the most suitable pipe size for each application. Allow
for the cold water piping to the water heater to be the same size or larger than
the hot water line from the water heater.
INLET/OUTLET CONNECTION
On the cold water inlet connection, carefully follow the installation diagram
(See Page 8 and 9). Always provide a union connection at the inlet and outlet on
the water heater to allow for disconnection of the water heater.
VENT PIPE
The vent pipe must not become blocked or obstructed. It should be checked
regularly to ensure it remains clear. The vent pipe may be extended downwardly
a distance not exceeding 1 metre, in the event of accidental discharge of hot
water through the vent pipe whilst checking the relief valve. To prevent the
possibility of collapsing the tank by creating a vacuum, a 3mm hole should be
drilled into the top of the elbow attached to the vent pipe. The vent pipe should
discharge at a visible point where water flow will not cause damage to property
or injury to persons.
Note: Thermostats above 80ºC will cause normal wafting steam which will condense
and drip from the vent pipe. (See Installation in ‘Confined Spaces’, Page 10)
