3. Install the hood body:

Fix the check valve as shown in Figure 5. Then direct the hanging holes in the back of the hood at the hooks of the 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).

Install the aluminum foil exhaust pipe

Drilling position of the aluminum foil exhaust pipe (public flues do not require drilling)

1. 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.
2. 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.
3. 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 the aluminum foil exhaust pipe without a 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 the public flue outlet or wall hole with scissors.

Then insert the end of the aluminum foil exhaust pipe with a 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.

Figure 4: Exhaust Pipe Components

[Diagram showing exhaust pipe, tape, connection, and check valve components]

Figure 5: Check Valve Assembly

[Diagram showing check valve assembly with buckle and slot]

Note: During installation, straighten the aluminum foil exhaust pipe to avoid noises in a semi-stretched state. Excess part may be cut with a wire cutter.

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.
