9. The inlet valve should be installed at the inlet of
the water heater; a gas shut-off valve should be
installed at the inlet of the water heater.
10. The outlet of the exhaust pipe must be outside
the house.
11. Users of liquefied petroleum gas should use
qualified gas pressure reducing valves and hoses
to ensure the normal operation and safe use of
the water heater. Users who use piped gas must
ask the gas company or the corresponding
management department to connect the gas
pipe.
12. The power socket must be grounded reliably.
Otherwise, the water heater should be grounded
reliably.
Typical Installation
1. Determine the installation location and
determine the installation height. The height of
the water heater's operation display panel and
the human eye level are appropriate.
2. When installing the water heater, keep it vertical
and do not tilt.
3. As shown on the right, first install the mounting
hole on the wall. The upper mounting hole is
fixed by the expansion screw, and the lower
mounting hole is inserted into the plastic plug.
Hang the water heater, place the washer and nut
on top, and tighten the nut. Screw on the self-
tapping screws below.
Precautions for installation of exhaust pipe:
1. The exhaust pipe must be installed when the
water heater is used.
2. The elbow and the straight pipe are combined
into a smoke exhaust pipe. One elbow is
equivalent to 6 ft. But the total length of elbows
and straight pipe must not exceed 25 ft (7.5m).
The total length of elbows and straight pipe must not
exceed 25 ft (7.5m).
3. The installation of gas water heater pipe should
be outward and downward the slope of 3° is
such that when the outdoor temperature is too
low, the condensed water does not flow back
into the interior of the water heater.
The flue duct should have a slope of 3° outward and
downward
4. When the flue passes through a wall made of
combustible materials, it must be covered with
an insulating flame retardant material greater
than 1 inch thick.
5. The flue should not be hidden in the ceiling as
much as possible. If it is unavoidable, it needs to
be wrapped with flame-retardant insulation
material, covering a thickness of 1 inch or more.
The distance from the flue to the combustible
item should be greater than 1 ft.
6. The gap between the flue and the round hole in
the wall through which it passes cannot be
permanently filled with cement to facilitate
maintenance.
7. The exhaust vents shall not be installed in the
ventilation of the building and on the common
flue.
