† Prohibited area below electricity meter or fuse box extends to ground level.
Horizontal Obstructions
The appliance must be in an accessible location. Sufficient clearances
shall allow access to, and removal of, all serviceable components.
A minimum horizontal clearance of 600mm between a building structure
and obstruction facing the terminal.
For correct operation of Rinnai external continuous flow water heaters
such a building structure MUST 'obstruct' the full front cover height of the
appliance (appliance dimensions, refer to "Dimensions" section), or extend
vertically above and below the front cover as shown a side.
There MUST be NO partial obstructions to the front cover of the appliance or any other parts of
the appliance casing. This will avoid the appliance failing to operate under windy conditions.
