Thermocore aluminized steel heat exchanger with venturi-design tubes
80% thermal efficiency
Aluminized steel heat exchangers (when inlet air temperature is below 40°F or temperature rise is less than 40°F, optional stainless steel heat exchanger is recommended)
Aluminized steel burners with stainless steel insert
120-volt supply voltage
BENEFITS
Eight sizes are available from 250,000 through 800,000 BTUH input.
Each furnace includes an integral power vent system which provides metered combustion air, dilutes flue products, and eliminates the need for vent caps.
The weatherized, aluminized steel cabinets are mounted on 12 gauge zinc grip rails designed for setting directly on a roof or slab surface.
Note: A separate blower system, such as Reznor model RBL, is required for air delivery
