Maintenance
1) Never use solvents to clean the body of water heater. Please wipe the surface with a soft, damp cloth, then
dry with a soft cloth.
2) If the water flow at the shower is reduced, the shower head may be blocked. Check and clean if necessary.
3) It is necessary for the appliance to be inspected and maintained regularly so that it can be used safely and
efficiently.
Trouble Shooting
The safety devices check operation of the water heater continuously. If a fault occurs, a fault code flashes on the
temperature display . This assists to handle the problem. Please quote the code displayed when enquiring about service.
In general, fault code is cancelled when closing and re-opening hot water tap. If the fault code persists, turn off power
supply and wait for 10 seconds. Then, turn on the water heater again. If the fault code still persists, please contact
Towngas Customer Service Hotline on 2880 6988.
In cold and humid weather, cloudy mist may be occasionally vented from the flue terminal. The white
smoke is the condensate of water vapour in flue gases. It is a normal phenomenon.
