installation planning
3.1.1 ventilation openings
It is recommended to provide air circulation within the enclosure by installing ventilation grilles (minimum openings
of 40 sq. inches (0.03 sq. meters) at both fl oor and ceiling levels of the enclosure). These grilles must not restrict
the fl ow of heat by more than 25%. Do not install into any area having a height less than 8 ft (2.4m) (ceiling of
enclosure to appliance bottom, excluding hearth height).
DIP
LOOP
OR
Insulating the intake liner is recommended in colder climates to prevent condensation from occurring.
It is recommended that a dip or loop is put into the duct creating a cold air trap in order to prevent cold air from
fl owing into the room when the appliance is not being operated (see illustration below).
The NZ7000 and NZ8000 take outside air directly into the appliance through the opening on the left side.
The fresh air inlet duct and hood must be installed lower than the fi rebox. Secure and seal the intake liner to the
collar using 3 sheet metal screws, and high temperature sealant.
The duct inlet must be located so they cannot be
blocked (i.e. snowdrifts). 12" (30.5cm) above grade
is recommended. Make a 4 ½" (114mm) inch
hole to suit in an outside wall of the house. From
outside, place the fresh air hood into the hole,
open side down. Seal with caulking and secure.
3.2 outside combustion air
It is recommended to install outside air to the appliance as this will help to prevent any smoke entering the living
space in homes that experience negative pressures. Check with local authorities having jurisdiction in your area,
as installing outside air to the appliance may be mandatory.
