Suburban Furnace Sf-20q

Item 79-1898 | MFR# SF20Q

These trailer heaters from Suburban provide maximum heating performance in a low-profile design. Suburban's SF Series furnaces provide maximum heating performance in a ducted unit, with capacities from 20,000 to 40,000 BTUH. 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.

"Q" stands for QUIET! Suburban Q series furnaces have been redesigned to be significantly quieter. By increasing the efficiency of the furnace blower to deliver more CFM, Suburban engineers were able to lower the motor RPM to deliver the same amount of air but at a substantially lower sound level.

SF-Q Models feature top or side rear gas and electrical connections, with an optional exterior access door for installation and service access. (the optional door is sold separately).

SF-FQ 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.

All SF Models also feature quiet, multi-ported stainless steel burners, sealed forced-draft combustion, automatic direct spark ignition and low amp draw. Cut-out size: 7-1/2" H x 17" W x 20" D.
