water inlet at the bottom of the appliance. See page 12, diagram1.

How the Challenger Water Heater Works
By turning on the hot tap the water will flow through the water heater
turning the water heater on. As the water circulates through the water
heater the water is heated.
By turning off the hot tap the water stops circulating through the water
heater, and the water heater turns off automatically.
The built in automatic safety features within t he water heater ensure that
the gas is turned off immediately the flame is extinguished.
Information about your Challenger LPG
Water Heater
• The Challenger LPG continuous flow water heater provides an
energy efficient method of heating water.
• For Challenger LPG Water Heater installations, please refer to the
New Zealand Gas Safety Regulations or consult with your
registered gas worker or installer.
• Challenger Water Heaters operate on low pressure LPG. They
require a low pressure gas regulator and can be used with a
portable LPG gas cylinder.
• The Challenger 5,6,7,8,10,12 & 16 litre models do not require a
power point (240 volt) and can be installed internally with a flue
system to vent the emissions to the outside. Internal installation
must comply with current New Zealand Gas Safety Installation
Standards & Regulations. The 5,6,7,8,10,12 & 16 litre models can
be installed externally provided the unit has adequate shelter to
prevent water from entering the unit and damaging the electronics
within the water heater.
