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-FQ is aesthetically appealing and a more economical installation choice. For design flexibility, all SF-Q Models feature identical cabinet dimensions and feature quiet, multi-ported stainless steel burners, sealed forced-draft combustion, automatic direct spark ignition and low amp draw.
