Product Overview
The Re-Verber-Ray UH-SS Series is the stainless steel version of the company's UH Series gas-fired, separated combustion, induced draft unit heater, built for washdown, humid, and corrosive-environment jobs in shops, barns, and industrial spaces. It uses a stainless steel cabinet and louvers in place of the standard black powder-coat finish where corrosion resistance matters. Each unit is fitted with individual in-shot burners, a swept-wing impeller with finger-proof fan guards for quiet operation, and stainless steel louvers with incrementally adjustable winglets to direct airflow where it is needed. Operational indicator lights help spot issues at a glance, and integrated mounting brackets keep installation straightforward.
The unit runs on natural gas or propane and ships in three input sizes, 60, 100, and 250 MBH, sized to the space it is heating: the 60 MBH size suits smaller shops and barns, the 100 MBH size covers mid-size spaces, and the 250 MBH size serves larger industrial or agricultural buildings that need more heat.
The line covers three models: UH-60-SS (28" W x 17" D x 17" H, 4" vent), UH-100-SS (40" W x 20" D x 21" H, 4" vent), and UH-250-SS (40" W x 20" D x 30" H, 6" vent). Propane conversion kits are matched by size: CKP-56-4 for the UH-60-SS, CKP-53-4 for the UH-100-SS, and CKP-53-1.55-9 for the UH-250-SS.
The UH-SS Series is separated combustion out of the box and can be field-converted to power-vented with no additional parts. Gas connections and venting should be installed and serviced by a qualified technician in accordance with local code. It is backed by Re-Verber-Ray's UH Series limited warranty, covering components, heat exchangers, and burners.
