● Gas inlet
(1) Before connecting the gas supply, check the rating plate on the right side of the right front
cover to be sure that the heater is rated for the same gas to which it will be connected.
(2) All such pipe shall be either new or previously used for no other purpose than conveying gas;
and must be in good condition and free from internal obstructions. Burred ends shall be reamed
to the full bore of the pipe. All fittings used shall be of malleable iron, yellow brass, or approved
plastic fittings. And flexible tube is not allowed.
(3) When your connections are made, check for gas leaks at all joints (this includes all existing
piping). Apply soapy water to all gas fittings and gas valve. Soap bubbles are a sign of a leak.
NOTE: No substance other than air, carbon dioxide or nitrogen can be introduced into the gas
piping.
NOTE: If you have a leak, shut off the gas. After verifying the leak, tighten appropriate fittings to
stop leak. Turn the gas on and check again with a soapy solution. Never test for gas leaks using a
match or flame.
● Cold water inlet
(1) When facing the heater, the cold water inlet is on your right and the hot water outlet is on
your left. Although water piping throughout your structure may be other than copper, we
recommend that copper piping be used for at least 0.92 m before and after the heater (follow
local codes). Keep water inlet pipe to no less than 1/2" diameter to allow the full flow capacity.
(2) Remember that water pressure must be sufficient to activate the heater when drawing hot
water from the top floor.If the hot and cold connections to the heater are reversed, the heater
will not function. 1/2''Copper or brass fittings work best when connected to the connectors. The
flexible type connectors will make instillation easier and seals to the water valve by means of a
union connection with a washer type gasket at the joint. No pipe dope or thread tape is to be
used at this joint. Be certain there are no loose particles or dirt in the piping. (Fig. 10)
(3) Water pressure must be sufficient to activate the water heater, the maximum pressure for the
appliance is 10bar,even with the effects of water dilation, the water pressure in the appliance
shall not exceed this value.
● Hot water outlet
Use a flexible or rigid pipe to connect with the sprayer without valve. If a valve or switch is
connected to the sprayer, the outlet pipe shall not use heat and pressure unendurable material
such as plastics, aluminum pipes, so as to avoid the pipe from breaking and scalding the user.
