Sealed Combustion & No Electricity Required!
Williams direct vent wall heater draws outside air to the sealed combustion chamber and vents exhaust gases directly outside. This feature is highly recommended if you grow orchids. No electricity required, so heater will continue to operate normally even during an electrical power outage. Great heating option for greenhouses, garages, rooms in homes, and work shops.

Williams Direct-Vent heaters are designed for quiet operation. Convenient, Piezo pilot ignition - simple push button system lights the pilot without matches. 100% safety shutoff. Compact cabinet takes up little space, projects into room less than 11". (Largest heater is 32" wide x 28" high.) The optional Blower increases air flow and distribution of heat. It can be added at any time. Designed for propane or natural gas. Mounting bracket and venting included. Can be operated with any millivolt thermostat.
