Warning
1.The air must not be discharged into a flue that is used for exhausting fumes from appliances burning gas or
other fuels,the discharge of air must fulfill the requirements of local regulations.
2.Note that when installing the metal expansion pipe, the pipe shall match with the hole in size. Overlarge hole is
prohibited, as it will result in loose pipe and accidental drops.
3.There shall be adequate ventilation of the room when the range hood is used at the same time as appliances
burning gas or other fuels.
4.If the flue aperture is less than air duct aperture, it will influence the fume suction effect and the too long air
duct will influence the fume suction effect, too.
5.This product is only for daily use and please do not use it under special environment (e.g. outdoor); nor can it
be used to exhaust hazardous or explosive substance or gas. Before assembly, the product shall be placed

2. Install hitching foot: according to the size of the hitching foot, drill four 60-70mm-deep holes on the wall
accordingly with an 10mm-diameter drill bit (overlarge holes are prohibited). Press the expansion pipe into
the holes, and then reliably fix the hitching foot with 4 accompanying ST4×60 wood screws. Drill a hole with
diameter of 10mm and depth of 50-55mm at the position 72mm above the four holes and insert the M6 metal
expansion pipe into the hole. (As shown in Figure 3)
3. Install the hood body: fix the check valve as shown in Figure 5. Then direct the hanging holes in the back of
hood at the hooks of hitching foot according to Figure 3, and press them together. Shake the body to check if
it's hung securely. After the body is mounted, install the hitching foot stopper and gaskets to the M6 metal
expansion pipe, and then tighten the nuts (to prevent accidental decoupling of the body under external force).
●Drilling position of the aluminum foil exhaust pipe (public flues do not require drilling)
a. Aluminum foil exhaust pipe and hob facing the window: Remove one of the glasses and install a plywood with
ventilation holes or punch directly on the glass.
b. Hob away from the window: Install the aluminum foil exhaust pipe through the window that is close to the hob
and connected outside; or install it by punching on the wall that is close to the hob and connected outside.

The exhaust wall hole diameter shall be close to that of the exhaust pipe, which shall not be too small. Otherwise, it
will cause poor exhaust efficiency, more noises and lower airflow, etc. The connection between the pipe and the
hole or the public flue must be sealed tightly to ensure that, the pipe and the check valve or public flue are
connected securely. The blades at the check valve connection or public flue connection must be flexible.
Figure 4
Note: During installation, straighten the aluminum foil
exhaust pipe to avoid noises in semi-stretched state.
Excess part may be cut with a wire cutter.
c. Drill hole through the wall: Determine the location of the aluminum foil exhaust pipe against the wall and draw
the drilling range (i.e. a circle slightly larger than the pipe OD). Then use a long drill bit to drill through the wall. Pay
attention to the wall structure and material, so as not to destroy other parts of the wall.
●Link the aluminum foil exhaust pipe
Insert the end of aluminum foil exhaust pipe without fixed strip to the pipe connection and stick with tapes, then
straighten the aluminum foil exhaust pipe and connect it to the public flue outlet (If there is no public flue, please
straighten the aluminum foil exhaust pipe to the outdoors). This can be done directly when the public flue outlet or
wall hole is larger than the aluminum foil exhaust pipe. Otherwise, there are five types of pipe small ends(OD: 140,
150, 160, 170 and 180 respectively) to be chosen from according to the hole size. Then cut the excess part smaller
than public flue outlet or wall hole with scissors.
Then insert the end of the aluminum foil exhaust pipe with fixed strip in the outer ring of the check valve connection
and seal with exhaust pipe tapes. At last, put four snaps of the check valve connection in corresponding slots, and
rotate them clockwise to fix the exhaust pipe to the check valve.
