Installation
Contact your local gas dealers or gas management department for a qualified engineer to install
the gas water heater (users are recommended not to install by themselves). The installer should
be called on to install and adjust the appliance, where appropriate.
This product is prohibited to use this gas water heater when flue pipe has not been installed
correctly according to instructions.
■Installation Requirements
• The flue of the gas water heater should be installed through an external wall, the heater cannot
be installed in outdoors. (Fig.3)

8
• The gas water heater installed in a suitably ventiled room , in accordance with the regulations
in force.. It is not allowed to install in the bedroom, underground, bathroom or any other places
with poor ventilation. (For B
23‐53 type)
• The flue of the heater cannot be connected to a common flue (Fig. 4).(Except for type B33)
• Please don’t install the heater in places where special chemicals are used, such as the laundries
or factories etc., otherwise it may cause rusting, shorten the lifetime of the heater, or prevent
normal working. (Fig. 5)
• Don’t install the heater above the gas stoves or other heat sources. (Fig. 6)
• The gas water heater should be kept away from the combustible materials with the distance
shown in Fig. 7 at least.
• When the installation parts' materials are combustible or flammable should be used frame‐
proof board to isolate, heat‐resistant plate and wall gap should be greater than 10mm,and the
size of heat plate should be larger than water heater shell for 10mm. (Fig. 8)
• The electric wires and electric equipment are not allowed to be placed on the top of the gas
water heater. The horizontal distance between the gas water heater and other electric
equipment should be more than 400mm.
• The power socket must have a reliable ground wire to improve safety. In order to reduce the
number of times of plugging, it is better to use a socket with a switch. Whenever the water
heater finishes working, please switch it off to avoid being electrified in a long term. The power
supply socket should not be installed in the moist environment.
• The socket should be installed at the side of the product, and never be installed below the
machine or the place with splashes, near the heat source, in exposure to sun and rain, or the
place where it is not easy tocontrol.
• The installation place of socket must be far away from the spraying space, so as to avoid

spraying the socket during shower.
■Installation Method
1. Installation of Gas Water Heater
Drill holes in the wall according to Fig. 9, put an expansion bolt into the upper hole and plastic
gasket into the lower hole, mount the water heater vertically on the upper bolt without
inclination and tighten the lower holes with expansion bolts.
2. Installation of water and gas pipes (Fig. 10)
• It can be used when the flue system can ensure that the provided gas pressure can reach the
lowest requirement. If gas water heater reaches the rated heat input, the gas pressure must
reach the rated heat input in the technologic parameterform.

10
• Gas inlet
(1) Before connecting the gas supply, check the rating plate on the left 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.
(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 thepiping. (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.

3. Installation of the flue:
The water heaters can be installed with the below types of flue pipes:
Type C83* (*only G20)
(1) The flue pipe shall be installed in accordance with the applicable regulations and instructions
of the professional installer. Once the pipe connection is complete, it must be checked and
ensured that it is properly sealed. Do not refit without permission.
(2) Depending on the actual installation environment of end users, adapters may be needed for
