Installation
Install only on an external wall, as close as possible to the most frequently used hot tap. Use a heat shield (accessory item part number 9 708 061 400) if the unit is to be installed on a combustible surface. Allow minimum air gap of 10 mm between the flue and the heat shield, (refer figure 2).
Ensure that the flue terminal is clear of any combustible material, and avoid installation in a marine environment.
Install the appliance such that the base of the appliance is not more than 1.3 metres and not less than 0.5 meters from the ground, and allow for easy access to service heater.
Secure heater to wall using two 10g X 5/16 hex head wood screws (Ramset 610041 or similar). Locate head of screw in the key hole of the top mounting bracket.

Hot and Cold water ½" male
Natural gas ¾" female
L.P. gas ½" male
A gas cock must be installed in the gas supply line with provision to disconnect the appliance. Install gate valve or full flow ball valve (fixed mechanism type) in cold water supply.
A non return valve must not be fitted. Example duo valve
We recommend that all hot water pipes be lagged if the runs are long or exposed, and
If installing a pressure limiting valve fit a cold expansion valve between the limiting valve and the appliance. PLV = 500kPa Cold expansion = 700kPa
Refer to AG 601 and AS3500.1 for the relevant pipe size.
NOTE:Service calls for incorrect pipe sizing will NOT be covered under warranty.
Water Filter
If sludge or foreign matter is or may be present in the water supply, it is recommended that a suitable filter be incorporated in the water supply line to the heater. All pipes should be well flushed before connection is made.
A water filter/strainer is installed in the inlet of the brass water valve inside the appliance.
Water Temperature Adjustment
Located inside the water heater, immediately below the gas controls, is a water temperature selector knob.
To increase the water temperature ( decrease water flow ) turn the knob clockwise. To reduce water temperature ( increase water flow ) turn the knob anti clockwise.
