Subject: Reznor 400E
These models are used as heating components in heating, heating/cooling, or makeup air systems and require a separate blower system for air delivery. The furnace has a Reznor® Thermocore® aluminized steel heat exchanger with venturi-design tubes. The die-formed burners are of aluminized steel and include flared ports with a stainless steel insert.
The HX Model does not include finger baffles and is approved for a temperature rise range of 20°F to 75°F.
Standard features include a manual match-lit pilot and a single-stage,24-volt gas valve. Model HX units are wired for field connection to aremote 24-volt thermostat for automatic operation. Each unit is provided with all required limit and safety controls, including an energy cutoff (ECO)and a blocked vent shut-off system.
2. For air inlet temperatures below 40°F or temperature rise less than 40°F, an optional stainless steel heat exchanger is recommended.
3. For temperature rise and pressure drop see tables.
4. Blower must be placed on entering side of furnace.
5. Approved for installation downstream of an air conditioning coil (optional drain flange, stainless steel heat exchanger, and stainless steel burners are recommended).
6. Not approved for residential use.
