The hood shall be installed right above the hob. The minimum distance between the bearing surface of
cooking appliance and the lowest part of hood is 650mm (larger space specified in the installation instruction of
gas hob shall be considered. The distance for electric cooker may be reduced appropriately, depending on the
actual situations)
The size of removable baffle (reference: 430mm) can be adjusted according to the actual situations. The
installation pitch of holes is shown in Figure 2. The hood body shall be centered vertically and kept level. Ceiling
hole size is shown in Figure 3.

●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.
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.
Straighten the aluminum foil exhaust pipe and then connect the pipe to the connection of public flue outlet
(straighten the pipe directly to the outdoor if there is no public flue). This can be done directly when the public flue
connection or wall hole is larger than the pipe. Otherwise, there are five types of pipe connection small ends (OD:
140, 150, 160, 170 and 180 respectively) to be chosen from according to the hole size. Then cut the excess part
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.

●Adjust drawing panel
Pull the two brackets of the drawing panel upwards to an appropriate height and then pull out the drawing
panel by holding both sides. Remove the protective film (excluding cold plate materials) on the drawing panel and
insert it along the gap between the main hood panel and the housing. Then adjust it to the proper height.
●Install hood body
Fix the check valve as shown in Figure 5. Then align the hanging holes in the back of hood with the hooks of
hitching feet according to Figure 2 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).
●Install drawing panel
As shown in Figure 1-1, there is certain gap between the drawing panel and the top plate. Push the panel
against the top plate and then fix it to the top plate with ST4×18 screws.
(If installation method in Figure 1-2 is adopted there’s no need to adjust and install the drawing panel)
