Tecnogas TNP HD ZEUS 1, Manual

INSTALLATION
1) Exhaust Ventilation 

Under this vented installation, the cooker hood’s air outlet will be connected
to the wall and reach the outdoor through a ducting. The cooking fumes and air 
in the kitchen will draw into the cooker hood and cleaned by the grease filters 
and then directed outside. The anti-backflow vent cap is needed for 
this operation mode. The anti-backflow vent cap will be fixed at the end 
of the ducting which is outside the kitchen at the opening on the wall. This vent cap
is to block the vented fumes and air flow back into the ducting and the vent cap 
will be closed once the cooker hood turns off. Diagrams below are some examples 
of exhaust ventilation

 (The cooker hood can be installed in different ceiling type)

2) Installation Instruction    

3) Installation Notes

Before installation, it is very important and needed to read and understand 

the stated safety notes, instructions and related information in this manual. 

This is to ensure the appliance could be installed appropriately and the user would 

use it in a proper method in order to avoid any unnecessary injury and damages. 

To avoid the risk of fumes suffocation, the cooker hood should be installed according 

to the stated instructions and notes in this manual. Next, the range hood has to install 

in accordance to the local building guides and regulations therefore please seek

approval from the building management or inspector if necessary before installation.   

4) Venting requirements

1. Do not vent the cooking fumes and air into attic, ceiling and any enclosed area.

2. Make sure the ducting is clean inside for efficient ventilation.

3. The recommended distance between the top surface of cooking hob 

   and the bottom part of the cooker hood is between 650mm to 750mm (can be 

   adjusted according to different cooking way). 

4. Make sure the mounting height is appropriate as the range hood could be 

   badly damage and in fire hazard if the range hood mounted too low. 

  If the range hood mounted too high, its performance and efficiency will be decreased. 

5. Both the size of the ducting and the size of air chamber outlet should be consistent.

6. Do not make the ducting turns 90oC more than 2 times as each turn will reduce 

   the airflow efficiency.

7. Make sure the ducting has a length of at least of 24 inches (61cm) before a 90 C

   turn and between 2 different 90oC turn in the same ducting. This is to allow the 

  drawn in fumes and air have enough room to push through the ducting smoothly. 

8. Minimize the length of the adopted ducting and the 90oC bents so the range hood

  could work at its best. Always make sure the total ducting does not go beyond

9. Please ensure the vent system is completely sealed, if not please use the silver tape

   or duct tape to seal it to ensure proper ventilation. 

10. Use silicon, plaster and etc. to seal the exterior wall opening or roof opening

    around the cap. 

11. If turns are needed in the installation, please make sure make it as far as possible 

    from the air chamber outlet.

12. If the ducting is directed into a central vent flue of a building or house, 

    the ducting outlet must be adjusted to the flow direction of the vent flue.
