Safety in the kitchen

When we think of a range hood, our first thought is that it's sole purpose is to removecooking odours and excess heat from the top of the cooking surface. The reality is that the range hood, when installed properly, is very effective in both removing any byproducts of natural gas or propane combustion as well as exchanging the stale air in the kitchen with fresh oxygen rich air from the outside.

Although make up systems are not mandatory in all regions some regions have created legislation to ensure make up air systems are installed and it is important for homeowners to consult with local building codes. The installation of a Falmec ducted range hood allows air to be changed efficiently which improves the quality of the environment in which you live.

Even if a make up air system is not required or mandatory in a specific application, simply opening a window to the exterior can effectively assist in this process. This is something to consider in many of todays air tight homes. Another factor to be taken into consideration is the distance between the top of the gas cooking surface and the bottom of the range hood.


General Tips for Installing the Range Hood

Range hood distance from the cook top.

Range hoods need to be correctly positioned in the center above a stove to perform safetly and effectively. The minimum distance between the countertop or burners and the hood must be at least 24" for electrical and 30" for gas burners. For you own safety DO NOT LOWER THE RANGE HOOD LESS THAN 30" FROM A GAS COOKTOP.


Make a level line.

Use the bubble level. Lay it against the wall and evenly position it with the height of the mark. Then apply a horizontal line of masking tape or low-tack painter's tape at the height of the mark; the length of the tape line needs to equal the width of the range hood. This tape should be removable and protects the wall from permanent measurement marks. Now lay the bubble level in place and make a series of marks to the width of the range hood. Use a straight edge along these level marks and draw a pencil line.


Make vertical lines to position the range hood.

Use a straight-edge framing square or a plumb-bob to find the true vertical position of the range hood. Many range hoods have square sides, and this line will set the position of the range hood side edge. Again, use painter's tape in the general location and make your final marks and lines with a pencil.


Locate the studs.

Range hoods are very heavy and must be well-fastened to the wall studs. Do not hang a range hood on the drywall or plaster alone. Use the stud locator to find the studs and make marks for the screws.



Vent Configurations

There are two different types of operation with regards to kitchen range hoods.

1. Externally ducted range hood, which expels kitchen fumes and odours outdoors. This system draws in clean air from outdoors and it allows the kitchen to be properly ventilated. This is the solution recommended by Bossino, due to the fact that it is a more efficient solution and it ensures a healthier environment within the kitchen.



The exhaust hole of the fan is located 15" above the bottom of the hood . The vent opening should be installed min. 85-90" from the floor. Keep the opening as close as possible ot the center above the stove.

Aspiration efficiency is influenced also by the length of the duct, by the number of elbows along the duct route and the diameter of the ducts. The longer the outlet duct is, the larger the diameter of the duct must be. Bossino always recommends the use of ducting with a minimum diameter of 5" to try and use the straightest route leading to the outlet vent, with the shortest run possible.

With regards to the external ducted range hoods, the outlet duct must have a diameter no less than that of the range hoods motor. It is recommended that along the horizontal lengths of the duct there must be a slight upward gradient (approximately 10%) in order to allow the air to flow out of the environment.

2. The ductless or recirculation range hood draws in air impregnated with cooking vapours and cleans it by means of special active carbon filters. This filtered air is then re-circulated back into the kitchen. Such a solution should be chosen only when it is not possible to install a ducted system which vents fumes outdoors. In order to maintain a highly efficient ductless filtering system, it is essential that the greaseproof filters should be periodically washed and the active carbon anti-odour filters be substituted.
Charcoal-filter or recirculated range hoods do not require external vents.



Stainless steel cover ( flue) installation- Vaulted & Drop ceilings

This range hood comes with adjustable cover, that covers ceilings from 8' to 9'. If you have a bulkhead ( drop ceiling) and your ceiling height is less than 8', you most likely will need to cut the cover at your local metal shop, or using angle grinder. To finish it, put a molding around the edge. It you have vaulted ceiling, again you will have to cut the cover on the spot, we do not offer kits that can fill up the gap.


Electrical Connections/Wirings

All Bossino range hoods come standard with plug however some installations require a special electrical connection; it is recommended that a qualified electrician be consulted. In any case, the connection must be carried out in compliance with local building codes and legislation.

All electrical wiring must be properly installed, insulated and grounded. Overly accumulated grease in old duct work should be cleaned out or duct work should be replaced if necessary to avoid the possibility of a grease fire. Check all joints on duct work to insure proper connection and all joints should be properly taped.
