Maximum Heating Performance in a Low-Profile Design. A ducted unit that is only 7 1/2 inches high, the Suburban SF Series furnace offers almost unlimited design flexibility in mid-size and large RVs. With nine duct connection choices (top, front, side, and bottom), it can be easily installed in areas that might otherwise be left unused. The SF Model features top or side rear gas and electrical connections, with an optional exterior access door for installation and service access. Cabinet size: H: 7.5”, W: 17”, D: 20”, WT: 32#. Voltage: 12VDC, Amp Draw: 7.0A. SF Series furnaces, with side (4” round) or bottom (4” x 14”) duct options, are easy to install and make an ideal replacement for obsolete competitive furnaces. All SF Models also feature quiet, multi-ported stainless steel burners, sealed forced-draft combustion, automatic direct spark ignition, and low amp draw.
