Exhaust-air mode
The exhaust air is discharged upwards
through a ventilation duct or directly
through the outside wall into the open.
D
Exhaust air should neither be directed
into a smoke or exhaust flue that is
currently used for other purposes, nor into
a shaft that is used for ventilating rooms in
which stoves or fireplaces are also located.
Exhaust air may be discharged in
accordance with official and statutory
regulations only (e.g. national building
regulations).
Local authority regulations must be
observed when discharging air into smoke
or exhaust flues that are not otherwise in
use.
Sufficient air is needed for proper
combustion and exhausting of gases
through the flue (chimney) of fuel burning
equipment to prevent backdrafting. Follow
the heating equipment manufacturers
guideline and safety standards such as
those published by the National Fire
Protection Association (NFPA), the
American Society for Heating, Refrigeration
and Air Conditioning Engineers (ASHRAE),
and the local code authorities.
Note: When assessing the overall
requirement, the combined ventilation
system for the entire household must be
taken into consideration. This rule does not
apply to the use of cooking appliances,
such as hobs and ovens.
All legal requirements concerning the
discharge of exhaust air must be observed.
❑ Due to size and weight of this unit two
installers are recommended.
❑ When cutting or drilling into wall or
ceiling, do not damage electrical wiring
and other hidden utilities.
❑ To properly exhaust air, be sure to duct
air outside – do not vent exhaust air into
spaces within walls, ceilings, attics,
crawl spaces, or garages.
❑ WARNING – TO REDUCE THE RISK
OF FIRE, USE ONLY METAL DUCT
WORK.
❑ Install this hood in accordance with all
requirements specified.
