CIRCULATED HOT WATER FLOW AND RETURN SYSTEM
A CG20-60 model continuous flow water heater can be installed as part of a circulated hot water flow and
return system in a building.
Notes:
the preset outlet temperature setting of the water heater must be set to at least 60°C.
Water should not be circulated from a water heater with a temperature setting of less than 60°C.
the preset outlet temperature setting of the water heater should be set to 70°C if the water temperature
decreases by more than 5°C through a circulated hot water flow and return system due to heat loss in
the ring main.
temperature controllers should not be installed with this water heater as part of a circulated hot water
flow and return system.
WARNING
This water heater is only intended to be operated by persons who have the experience or the knowledge and
the capabilities to do so. This water heater is not intended to be operated by persons with reduced physical,
sensory or mental capabilities i.e. the infirm, or by children. Children should be supervised to ensure they do
not interfere with the water heater.
The water heater uses 240 Volt AC electrical power for operation of the control systems and the combustion
fan. The removal of the front panel will expose 240 V wiring. It must only be removed by a qualified person.
The power lead from the water heater must be plugged into a weatherproof electrical outlet. Take care not to
touch the power plug with wet hands.
SAFETY
This water heater is supplied with temperature sensors, a
FlameSafe™ protection system and a pressure
relief valve. These devices must not be tampered with or removed. The water heater must not be operated
unless each of these devices is fitted and is in working order.
If the power supply cord or plug is damaged, it must be replaced by a qualified person in order to avoid a
hazard. The power supply cord and plug must be replaced with a genuine replacement part available from
Aquamax. Phone Aquamax Service to arrange for an inspection.
Warning: For continued safety of this water heater it must be installed, operated and maintained in
accordance with the Owner‟s Guide and Installation Instructions.
The Aquamax warranty may not cover faults if relief valves or other safety devices are tampered with
or if the installation is not in accordance with these instructions.
Do not store flammable or combustible materials near
the water heater. Flammable liquids (such as petrol),
newspapers and similar articles must be kept well away
from the water heater and the flue terminal.
Do not use aerosols, stain removers and household
chemicals near the water heater whilst it is working. Gases
from some aerosol sprays, stain removers and household
chemicals become corrosive when drawn into a flame.
Do not store swimming pool chemicals, household
cleaners, etc., near the water heater.
Do not place anything on top of the water heater or in
contact with the flue terminal. Ensure the flue terminal is not
obstructed in any way at any time.
Do not use Propane / Butane gas mixtures in a Propane model. A Propane model is designed to operate
on Propane only. The use of Propane / Butane mixture, such as automotive LPG fuel, in a Propane
model is unsafe and can cause damage to the water heater.
