2.Installation of pipes
(a).Connection of the cold water supply pipe:
• The cold water inlet joint is G1/2 pipe thread.
• The water inlet pipe must be connected by using metal tube, or by rigid water pipe.
• The inner diameter of the inlet pipe (including the valve) shouldn’t be less than 8mm.
• The cold water valve should be installed with the water inlet pipe.
• Please ensure that the filter in the cold water inlet is mounted correctly.
Clean the new pipes by flushing with water. Make sure there are no blockages, then
insert the rubber gasket and fix the water inlet joint tightly.
(b).Connection of the hot water supply pipe:
• The hot water outlet joint is G1/2 pipe thread.
• The hot water outlet pipe must be connected by metal tube or by rigid water
pipe or by rubber pipe with sprayer directly.
• The inner diameter of the hot water pipe outlet pipe (including the valve) shouldn’t be
less than 8mm.
(c). After installation, please open the cold water valve to the maximum to test the flow of
water and check whether there is water leakage.
(d). Installation of the gas supply pipe:
• The gas inlet joint has a G1/2 pipe thread. Make sure that the gas inlet pipe joint and
rubber gasket is connected. The special soft rubber tube can be used according to the
technical parameters. Securely fit the pipe with the clip. Note: Gasket must be inserted,
otherwise you will experience a gas leak.
• After the gas inlet joint is connected, open the gas supply valve, and check whether
there is a gas leak at the joint with soapy water.
• Liquified petroleum gas users should use a good quality low pressure adjusting valve
with a flux above 0.6m/h.
3.Installation of exhaust device:
(a) According to the outline dimension of the attached flue pipe, make a hole with the
diameter a little larger then the flue pipe at a suitable position to easily install the flue pipe
horizontally easily.
(b) The installation of the flue is shown in the
Drawing 10. The total height of the exhaust pipe
should be more than 2.3 meters and the
horizontal length must not exceed 3 meters.
There must be a vertical ascending flue pipe and
the hole should not be less than 250mm above
the exhaust pipe cover. The gap between the
flue pipe and the hole should not be filled with
cement, otherwise repairs will be difficult.
(c) Install an exhaust fan not lower than the top of the
water heater.
