Tpi 3320ex33/afaex33 4 Inch Surface Mount Frame Wall Heater

Product Description

The TPI 3320ex33/afaex33 is a 4-inch surface mounting frame designed for field installation on the 3320 Series Commercial Fan Forced Wall Heater. This frame provides a clean, finished appearance when a wall heater is surface-mounted rather than recessed, closing the gap between the heater housing and the wall surface. It is a field-installed accessory, meaning it is added during or after unit installation rather than pre-configured at the factory. HVAC technicians and commercial electricians working on wall heater installations in commercial settings are the primary installers of this frame. ETL listed for both Canada and the United States. Manufactured in the USA.

This surface mount frame is applicable to commercial environments where the 3320 Series Fan Forced Wall Heater is installed directly onto a wall surface without a recessed rough-in. Typical install scenarios include retrofit applications, hard-wall construction where wall cavity access is limited, or new commercial builds where a surface-mount configuration is specified. The frame is sized at 4 inches to match the heater profile and delivers a professional, finished look at the wall interface.
