wet conditions.
Minimum clearance around the windows and doors must be maintained - refer to AS/NZS 5601.
In areas where water pipes are prone to freezing, drain lines must be insulated, must not exceed 300
mm in length and are to discharge into a tundish through an air gap of between 75 mm and 150 mm.

The water heater should be located as close as possible to the most frequently used hot water outlet.
