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.
