General installation information
Catch pan
It is important a suitably drained catch pan is tted (especially for internal units) where
damage could be caused by discharge from the water heater. Provision must be made for safe
disposal of any leaking water to an external location.
Flued water heaters (internal units)
The chart below highlights the maximum ue length and number of bends. It also shows the
difference between a short and long ue—this is important if changing settings (dip switches).

Mounting the appliance
Refer ‘Connections and Fittings’ for individual appliance weights. The wall or structure on which
these units are to be mounted must be capable of supporting these weights and the associated
pipe work.
Ensure suitable xing screws or bolts are used to secure the units to the walls, in accordance
with NZS 5261 (section 5.0). Wooden plugs shall not be used.
The top bracket has a keyhole slot (circled below) so the appliance can be positioned by
hanging it on one screw while the other screws are secured.
