The recessed flush mount frames from Infratech have always been a popular choice among architects, interior designers, and engineers working on high-demand commercial and residential properties. These frames are compatible with 33", 39", and 61" heaters and it is recommended to flush mount W-Series or WD-Series heaters. They can be installed with the edges exposed or partially covered by materials like drywall, plaster, stucco, or tongue-and-groove ceilings. These frames are ideal for spaces with lower ceilings or where hanging fixtures is not feasible due to limited height. However, it is important to note that these frames and heaters cannot be mounted on a sloped pitched ceiling. Flush mount applications must always be installed with heaters positioned horizontally on a flat, non-sloped ceiling. Please be advised that a licensed contractor is required for installation.
