The Suburban SF-42Q Furnace provides maximum heating performance in a ducted unit with a 40,000 BTU/h capacity. Yet at only 7.5" high, it can be easily installed in areas that might otherwise be left unused. With nine duct connection choices (top, front, side, and bottom), the SF-42Q offers almost unlimited design flexibility in mid-size and large RVs.

The SF-42Q Model features top or side rear gas and electrical connections with an exterior access door for installation and service access. For design flexibility, all SF-Q Models have identical cabinet dimensions and feature quiet, multi-ported stainless steel burners, sealed forced-draft combustion, automatic direct spark ignition, and low amp draw.
