The expanded Side Wall Vent System Reference Guide brochure includes sizing and specifications on its full line of Side Wall Power Venters and accessories. According to the manufacturer, side wall venting is an affordable option to conventional chimneys and increases living space by eliminating chimney chase. It is ideal for electric to gas/oil conversions, renovations, new construction, or for replacing old chimneys, says the company. Most of the manufacturer’s models include the UC1 universal control, which interlocks with any burner circuit. LED status and diagnostics simplify new installations and service calls. Also available are multiple appliance interlock options.
