The purpose of this manual is to give the contractor
guidelines for installing the LIFEBREATH Clean Air
Furnace. All national and local codes relating to this
type of equipment must be followed.
Locating The Unit
The Clean Air Furnace is designed to be installed
vertically, (unless it is designated as a Horizontal
unit ”H”), in a conditioned space, where the
surrounding temperature does not fall below
50°F (10°C). Attic installations are not recommended.
Typically the unit is installed in a mechanical area of
the basement, or other partitioned mechanical
room, elsewhere in the home.
A location close to an outside wall is
recommended, as the ventilation supply and
exhaust portion will need to be ducted to the
outside air. Sufficient clearance around the unit is
required for service of the filter, heat recovery
core and components. As a rule this unit should
be installed adjacent to the hot water heater. If
this is not possible, or if the piping layout is
complex, the total head pressure on the pump
should be calculated.
Duct Connections
To accommodate various installations, the Clean
Air Furnace has knockouts for the return air
plenum and ventilation ducts, on both sides of the
cabinet. Special care and attention should be
given to determining which knockouts are to be
removed.
Slide Heat Recovery Core out to remove
ventilation knockouts. Never install ductwork
directly to the cabinet that is smaller than the
opening provided.
INSTALLATION
Option 1 - Ventilation Ports Off Left Side
NOTE: Return plenum opening can be on either side of cabinet and is not dependent on which side the ventilation ports are on.
