Designed with you in mind; Empire Vent Free Heaters offer convenient, easy to operate controls on the top of the unit. The pushbutton igniter lights the pilot, eliminating the need for matches. Each unit is test fired in the factory and contains an oxygen depletion sensor that shuts off the unit if not enough fresh air is available. Empire Vent Free heaters are whisper quiet and use a state of the art powder coat process that produces a durable, scratch resistant finish.
