10 maintenance and service
Kelvinator gas continuous flow hot water system
Preventative maintenance can maximise the lifetime of this
system. It's therefore recommended to have this system
checked and serviced every 3 years. All servicing and repairs
must be completed by a licensed technician. Please call
the service centre (numbers located in the warranty section
of this manual) for servicing and spare parts for your gas
continuous flow hot water system.
warning
Turn off the electrical power supply and close the manual
gas control valve and the manual water control valve before
servicing.
caution
Before servicing or performing any maintenance on the
hot water system, first ensure that the water heater is
disconnected from the power supply to protect it from
being damaged due to air in the system.
• Clean the cold-water inlet filter.
(Refer to the diagram below right)
• Be sure that all openings for combustion air are free from
blockage. If blocked, remove the obstruction.
• Check that the opening for exhaust is not blocked. If
blocked, shut off the water heater’s combustion. Wait
until the system has completely cooled before removing
the obstruction. DO NOT touch while the system is
running – extremely high temperature can cause
severe burns.
• Check the gas pressure.
• Keep the area around the system clear. Remove any
combustible materials, gasoline or any flammable
vapours and liquids.
Water heater draining and filter cleaning
1. Close the manual gas shut off valve.
2. Turn off the power supply to the system.
3. Close the manual water shut off valve.
4. Open all hot water taps in the house (bathroom, kitchen,
laundry room, etc.). When the residual water flow has
ceased, close all hot water taps.
5. Have a bucket or pan to catch the water from the water
heater’s drain plugs. Unscrew the drain plugs to drain all
the water out of the water heater.
6. Wait a few minutes to ensure all water has
completely drained.
7. Clean the filter: Check the water filter located within the
cold inlet. With a tiny brush, clean the water filter of any
debris which may have accumulated and reinsert the filter
back into the cold water inlet.
8. Securely screw the drain plugs back into place.
Hand- tighten only.
When it is safe to use the gas continuous flow water
heater again:
• Ensure that power is switched off to the water heater
or that it is unplugged.
• Make sure all hot water taps are closed and the drain
plugs are securely attached.
• Purge the water line of debris.
• Turn on the manual water control valve located on the
water supply line.
• Open all the hot water taps to verify water flows to the
taps. Close hot water taps.
• Turn on the manual gas control valve located on the gas
supply line and check for leaks.
• Turn on the power supply to the system.
