Turn ON the Hot Water Heater
Warning!
Before operating the hot water heater, make sure to read and follow the below instructions, all labels on the water
heater, and the “Important Notes” contained in this user manual.
ONSEN hot water heaters do not have a pilot. The hot water heater is equipped with ignition device which
automatically lights up the burner. Do not try to light the burner by hand.
Before operating, smell around the appliance to determine if there is a gas leak. Be sure to also note any
smell coming from ground level because some gases are heavier than air and will settle on the ground.
If you smell gas,
o
Do NOT try to light any appliance.
o
Do NOT touch any electrical switch.
o
Do NOT use a phone within the vicinity of the heater.
o
At a safe distance from the heater, immediately call your plumber or gas supplier for advice.
o
Do NOT return to your home until being authorised to do so by the plumber or gas supplier.
Do NOT use this appliance if the internals have been wet or submerged in water. Call a qualified service
technician to inspect the appliance for damage.
The temperature setting and the delivered water temperature could be different due to the heat dissipated
through pipes and / or seasonal change. It is sound practice to occasionally measure the actual output
water temperature, particularly in systems where a temperature control valve is installed.
Reduce water delivery flow if the flow exceeds the water heater specification to avoid a hot water shortage.
Increase water delivery flow if the temperature of the delivered water is higher than the set temperature
setting, this might due to higher water supply temperature.
ONSEN hot water heater will stop working if the hot water delivery volume is lower than 2.5Lpm.
After an installation or a gas cylinder change, allow for a fluctuation with water delivery temperature until
the air in the gas pipe is purged.
If any water outlet is turned on before the hot water heater is powered on, the hot water heater will not
function and it will be in safety protection mode. Please turn off the water outlet and power on the water
heater again.
CLOSE mechanical service valve at gas line if the water heater is subjected to overheating fire, flood,
physical damage, or if the gas supply fails to shut off.
Do NOT turn on the water heater unless the heater has uninterrupted water supply.
Do NOT turn on the water heater unless the heater has uninterrupted gas supply.
Water temperatures above 50°C can cause severe burns; such scalding may result in death – see Figure 31.
Safety MUST be considered while setting the hot water delivery temperature. Table 3 shows that a person
will receive a second degree burn in 3 seconds of exposure and a third degree burn in 5 seconds of
exposure to water of 60°C. A maximum temperature of 50°C at the water outlet will ensure the most safety
for users.
Children, disabled and elderly are at most risk of being scalded.
Test delivery water temperature before showering or taking bath.
