We will no longer be manufacturing this line of products and will be replacing them with the modular line. This change is due to the increased capabilities of the modular line and to forward the greatest cost savings to our customers.

Direct Gas-Fired Heater, ETL Listed, for use in tempering make-up air. Packages are certified to the ANSI Z83.4a-2001/CSA 3.7a-2001 combined safety standard and produce up to 1,000,000 BTU/HR, depending on heating requirements. Units are designed for natural or propane applications and are rated for indoor/outdoor installations in commercial occupancies.

The heaters are intended for indoor or outdoor installations in commercial kitchens, factories, foundries and similar commercial and industrial occupancies where unvented open-flame combustion equipment is permitted. They are intended to be installed and used in accordance with the Standards of the National Fire Protection Association, NFPA No.54 and the National Fuel Gas Code.

A unique feature is the self-adjusting burner profile plates allowing 2-speed and variable-air-volume applications. The plates ensure proper air velocity and pressure drop across the burner for clean combustion. Spring-loaded profile plates react to the momentum of the fresh air stream, therefore, no motors or actuators are needed to drive them, nor do they need to be manually set to a specific position.
