Abstract
Abstract This invention relates to improvements in heaters and more particularly to fireplace insert heaters. The invention relates to a cabinet for such heaters which provides a removable panel which is slidable relative to remaining portions of the heater to enable access to a flue connection for a firebox of the heater to thus enable the heater to be readily installed or removed from an in situ flue installation. The invention provides a removeable portion of a wall of the cabinet which when removed facilitates access to and connection and disconnection of the flue.
