Adjustable grilles should be used to balance the flow rates into and out of various rooms. The
grilles should not be adjusted after balancing the unit.
Grilles or diffusers should be positioned high on the wall or in the ceiling. Kitchen exhaust should
never be connected to the range hood. They should be installed at least 4 ft (1.2 m) horizontally
away from the stove.
Field supplied balancing dampers should be installed external to the unit to balance the amount
of stale air being exhausted with the amount of fresh air being brought into the house. Refer to
airflow balancing section.
The Lifebreath Kitchen Grille includes a
removable grease filter. Most building codes
require that kitchen grilles are equipped
with washable filters.
