How to Flush Mount an Infratech W-Series WD-Series Heater

Our flush mounting option has long been a favorite among the interior designers and architects who develop today’s most sought-after commercial and residential properties. A flush mounted Infratech heater can provide warmth without disrupting the décor of the space – the flush mount frame can be installed with the edges exposed, or can be covered by a drywall, plaster, stucco, or tongue-in-groove wood ceiling treatment. It is also easy to install and operate.
