Installation
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.
