Big Discount RV

Suburban’s SF Series furnaces provide maximum heating performance in a ducted unit, with capacities from 20,000 to 40,000 BTUH. Yet, at only 7 1/2 inches high, they can be easily installed in areas that might otherwise be left unused. With nine duct connection choices (top, front, side and bottom), as well as models for interior and exterior installation and service, the SF offers almost unlimited design flexibility in mid-size and large RVs.

• SF Models feature top or side rear gas and electrical connections, with an optional exterior access door for installation and service access.
  
• SF-F Models are designed for interior serviceability with a front (inside) gas connection and only a small vent terminal on the coach exterior, permitting installation up to 9 inches from the wall. Since no exterior access door is required, the SF-F is aesthetically appealing and a more economical installation choice.
  
• For design flexibility, all SF Models feature identical cabinet dimensions.
  
• All SF Models also feature quiet, multi-ported stainless steel burners, sealed forced-draft combustion, automatic direct spark ignition and low amp draw.
