Installation

Concrete Slab

The first step in unit installation is to pour a concrete slab capable of holding the unit weight as a base. The slab should have a proper gravel drainage bed.

Concrete Slab and Unit Footprint

Service and Access Clearance

The slab should be positioned to allow 3 feet of clearance on the control end of the unit and 2 feet of clearance on the other three sides. Housing size 50 requires 3 feet of clearance on both ends because of filters access. Note that the concrete forms a 1 foot wide apron on all four sides of the unit unless a 42 in. extension is added to the control end of the unit.

Clearance to combustibles is defined as the

minimum distance required

between the heater and adjacent combustible surfaces to ensure the adjacent surface’s temperature does not exceed 90 degrees above the ambient temperature.

Burner/Blower Section

Use a crane and a spreader bar hooked to the factory lifting lugs (shown below) to lift and center the unit onto the filter stand section. The sections should be caulked together.

Install Ductwork

This table shows the duct sizes and straight lengths recommended for optimal performance (AMCA Publication 201-90). Using duct sizes less than recommended will affect fan performance. Good duct installation practices should be followed for the remaining ductwork.
