操作指示
•火焰失效：火焰感應棒除監察正常的燃燒外，當沒有火焰時，感應棒會將火焰失效訊號傳送到主控板，
以停止供氣到燃燒器。
•殘火安全裝置：當水龍頭已經關閉而火焰仍然存在，而在熱交換器內的水溫高達 90℃時，雙金屬安全
裝置會關閉電磁閥停止供氣。
•過度沸騰：當熱水溫度高於 85℃，熱水熱敏電阻訊號將傳送到主控器停止供氣。
•水流量感應裝置：若進入的水流受到阻隔或被中止。水流量感應器會停止傳送磁脈衝訊號到主控器，
並停止供氣。
•熱交換器過熱保護裝置：若熱交換器燒毀或溫度高達 139℃ 時，過熱保護裝置會啟動，停止熱水爐
運作。
•防止過高水壓裝置：若熱水爐內的水壓高於 1900kPa，置於熱水出口的洩壓閥會打開，釋放已累積的
壓力，待水壓降回 1370kPa 的水平才會關閉。
•助燃風扇轉速檢查：風扇的轉速由檢速器所監測；若風扇轉速與要求速度有所偏差，訊號將會傳送到
主控器，而轉速亦會作出相應的調整。
•NS11RM熱水爐可以提供每分鐘11公升流量，升溫 25℃的熱水，適合在不同季節的一般沐
浴使用。您可以在控制面板設定所需的熱水溫度，熱水爐將會自動調控出水溫度。但是在一
些特殊情況下，除通過控制面板設定熱水溫度外，可同時調節熱水流量，以便達到所需溫度。
•在冬季偶有極寒冷的天氣，自來水的溫度可能過低或熱水流量過大，熱水爐的出水溫度可能
低於設定的溫度，您可以調節水龍頭或花灑掣來減少熱水流量，以便獲得適合的水溫。

Important Safety Instructions
Caution
Regarding use
•Do not use the water heater for purpose other than to supply hot water for use in bathroom or kitchen.
This is intended to prevent accidents or damage.
•Do not use water from the water heater for drinking or cooking.
•This appliance is for general domestic use. Be aware that frequent, long-term commercial use will
dramatically shorten the life of the appliance.
Regarding installation
•Do not place or install at outdoor.
•Minimize pipe length and avoid dead legs and stagnant corners in hot water pipework.
•Minimize the distance between hot water outlet and water tap.
•When installing the flue terminal, make sure the flue gas does not discharge directly to the outside
walls, windows, glass, mesh doors or aluminum sashes etc. This could cause material disfiguration or
discolouration.
Regarding use of control
•Keep the control unit out of reach of children. It is intended to
prevent unexpected accidents or damage.
Regarding operation
•If water heater is not used for more than one week, drain away stagnant water pipework before use.
•During water purging, avoid generation of water mist. Use extension pipe to connect water outlet and
drain point.
•Method of water purging: Turn off water heater and fully open the most distant hot water tap from the
water heater for 1 minute.
•To save energy, switch off water heater completely when hot water is not used.
Regarding cleaning and maintenance
•If chlorine-based fungicides, acidic bathroom cleaners or deodorants, or salt touches the appliance or
gas pipe etc, wash them off with ample water straight away. They could cause unforeseen accidents or
damage.
•Do not use solvent or oil-based cleaners to clean the appliance. This could cause discolouration or
disfiguration.
•Do not use other than genuine parts for this appliance. This could cause accidents or damage.
Checking appliance set up
•Is the appliance set up on an even plane?
•Are the air intakes and outlets of coolers, heaters and air-conditioners away from the appliance? These
can interfere with proper combustion.
•Are there any shelves from which things could fall onto the appliance?
•Ensure there is sufficient space for maintenance of water heater.

Operating Instructions
•Flame failure: Apart from monitoring combustion, flame rod will send the flame failure signal to the main
controls when there is no flame for stopping the gas supply to the burner.
•Remaining flame safety device: If the flame remains on the burner after the water tap has been turned
off, and the temperature of the water inside the heat exchanger reaches 90℃ , bi-metal safety device
shuts off the solenoids and stops gas supply.
•Over boiling: If the hot water temperature reaches 85℃ , hot water temperature thermistor will send
signal to the main controls to stop gas supply.
•Water flow sensing device: Should the water flow coming in become restricted or stop, then the water
flow sensor will cease to send a magnetic pulse signal to the main controls for stopping gas supply to
burner.
•Heat exchanger overheat protection device: If the heat exchanger burns out, or the temperature reaches
139℃ , overheat protection device will activate and shut down the water heater.
•Over pressure protection device: If the water pressure inside the water heater is over 1900kPa, the
pressure relief valve located near hot water outlet will open to release the built up pressure until it reduces
to 1370kPa and it will then closed.
•Combustion fan revolution check: The fan revolution speed is continually monitored by a sensor. If the
fan speed deviates from the required speed, a signal is sent to the main controls and the speed will be
adjusted accordingly.
•
NS11RM water heater is capable to deliver 11L/min hot water at 25℃ temperature rise, which is
suitable for usual bathing purpose for all seasons. You can select the desired temperature by setting
temperature on control panel and the water heater will automatically provide hot water at that
temperature. However, under some exceptional situation, in addition to setting temperature on control
panel, you may require to adjust the water flow to attain the desired temperature.
•In winter, there may be occasional extremely cold weather where supply water temperature is exceptionally
low or required water flow is too high, the temperature of hot water may be less than the selected
temperature. You may appropriately reduce the hot water flow by adjusting water faucet or shower tap to
attain the suitable hot water temperature.
•In summer, there may be occasional extremely hot weather where supply water temperature is exceptionally
high or required water flow is too low, the temperature of hot water may be higher than the selected
temperature. You may appropriately increase the hot water flow or mixing with cold water by adjusting
water faucet or shower tap to attain the suitable hot water temperature.

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 device will check the operations of the water heater continuously. If a fault occurs, a fault code will
flash on the display screen of the control. This assists with diagnosing the fault, and may enable you to
overcome a problem without a service call. Please quote the code displayed when enquiring about service.
In some cases, fault code may clear when closing and re-opening the hot water tap. If the fault code does not clear,
turn off power supply and wait for 10 seconds. Then, turn on the water heater again. If the fault code still persist, please
contact Towngas Customer Service Hotline on 2880 6988.
In cold and humid weather, cloudy mist may occasionally vent from the flue terminal. The white smoke is the
condensate of water vapour in flue gases. It is a normal phenomenon.
60min. continuous combustion Close the hot water tap, turn off the ON/OFF button and turn on operation again.
Ignition failure Turn off the ON/OFF button, and then check whether the gas valve is opened and the
gas supply is not interrupted. If gas supply is normal, press ON/OFF button to switch on
water heater. If there is no fault code display when the hot water tap is opened and
closed several times (wait for 10 seconds for each interval), then the unit is operating
normally. If the fault code still persist, contact Service Hotline.
