Complete, low-profile ducted furnace with direct spark ignition, designed for interior serviceability with no exterior access door required.
The Suburban Mfg 2555A (SF-25FQ) is a complete 25,000 BTU/h furnace built for mid-size and large RVs. At only 7-1/2" tall, it's a low-profile ducted unit that fits into spaces that might otherwise go unused, while still delivering maximum heating performance. It's designed for interior serviceability, connecting to the gas line from the front (inside) of the unit, with only a small vent terminal on the exterior of the coach - no exterior access door is required, making for a more economical, aesthetically clean installation, permitted up to 9" from the wall.
With up to nine duct connection choices (top, front, side, and bottom), the SF-25FQ offers considerable design flexibility during installation. It features quiet, multi-ported stainless steel burners, sealed forced-draft combustion, automatic direct spark ignition, and a low amp draw for efficient 12V DC operation.
This is the complete furnace unit, including the burner assembly, ignition system, and blower - not just the outer cabinet/housing. If only the cabinet/shell is needed as a standalone replacement part, Suburban's part #103141 is the cabinet-only option for the SF-25FQ, SF-30FQ, and SF-35FQ models.
