Forced Exhaust & Air-Supply Type
Introduction of Gas Fired Balanced Flue Water Heater
1. The outer casing is sealed. The flue, integrated with the outer
casing, has two layers and reaches to the outdoor through wall.
Oxygen enters from outside through the outer layer of the flue, and
the burned gas is emitted to outside through the internal layer of
the flue.
2. Gas fired balanced flue water heater is popular in developed
countries, due to its high safety, multiple functions, convenient
usage and high performance.
3. It is the safest water heater by far. It can work with flue to
form a sealing system which isolates the indoor air and will not
consume indoor air or pollute it. The oxygen needed for combustion
is taken from outdoor, and exhaust gas is emitted to the outside.
In this way, oxygen indoor will not be consumed, and no indoor
anoxia will occur. Therefore, forced exhaust and air-supply water
heater can be installed in the bathroom.
4. In view of the development history of water heater, forced
exhaust and air supply water heater is the tendency and best
choice, and it makes water heater indoor installation become a
reality.
Advantages of Gas Fired Balanced Flue Water Heater
1. It is endowed with good safety, high heating speed, large water
flow, high thermal efficiency, stable temperature, little
incrustation, environment protection and tiny space occupation and
free of control of water flow.
2. Outer casing of forced exhaust and air-supply water heater is
fully sealed and gas is exchanged outside, which will not consume
or pollute indoor air.
Comparison
Flue Type
Not safe enough
The combustion product generated during combustion is emitted
directly to the bathroom, and the air for combustion is taken from
the bathroom too. It is easy to cause CO poisoning and insufficient
oxygen supply, so flue type can’t be installed inside the bathroom.

Not safe enough The combustion product generated during combustion is emitted
directly to the bathroom, and the air for combustion is taken from
the bathroom too. It is easy to cause CO poisoning and insufficient
oxygen supply, so it can’t be installed inside the bathroom.
| Much safer than flue type The combustion product generated during combustion is emitted out
of the bathroom through a flue, but the air for combustion is still
taken from the bathroom, which may cause hypoxia. It is highly
suggested not to install this type of gas water heater inside the
bathroom. The difference between the flue type and forced exhaust
type is that the forced exhaust type has a fan to forcedly blow or
vacuum the combustion product out of the bathroom through a flue,
but the China flue mounted gas water heater is to naturally emit
the combustion product out of the bathroom with a flue (not
included, optional). Therefore the evacuation of the combustion
product of the forced exhaust type is more complete than that of
flue type.
| The safest of all The combustion product generated during combustion is forcedly
emitted out of the bathroom through a flue, meanwhile the air for
combustion is forcedly inhaled from outside through the flue, so it
wouldn’t consume or pollute the air inside. It is the safest and
the only type that can be installed inside the bathroom.

Notes
1. Read and follow the instructions in the user manual provided by
the manufacturer of the gas heater
2. Use forced exhaust and air-supply water heater only after it is
installed and tested by registered gas installer employed by
registered gas contractor.
3. Stop using it immediately if faults or abnormalities are
detected. Notify the appliance dealer for follow-up action
4. If gas leak is detected, turn off the main gas switch
immediately, and notify the appliance dealer. Do not use the gas
water heater until it has been repaired.
Maintenance of Gas Fired Balanced Flue Water Heater
1. Gas exhaust flue must be installed on the outer wall which
connects the air.
2. Gas exhaust sleeve must be firmly linked to the gas water heater
and ensure good air-tightness.
3. Installation must be performed by professional installation
company.
Clearing and Maintenance of Gas Fired Balanced Flue Water Heater
1. Read and follow the instruction for the clean and maintenance of
gas water heater.
2. Ensure the room is in good ventilation.
3. Stop using the gas fired balanced flue water heater when there
is
