Installation Instructions for Lay-In Diffusers (-6 Border)
This section applies to all Greenheck diffuser models that are available in a -6 Lay-In Border Frame style.
A. Locate the lay-in location in which the diffuser will be
installed. This could be a plaster frame used in a hard
surface ceiling, or a standard T-Bar grid system.
B. Turn the diffuser on its side and push it up through
the opening diagonally. Take care not to impact any
side of the diffuser to avoid scratching or damaging
the diffuser – see Figure 1.
C. Once the diffuser is above the ceiling opening, lay
the product into the plaster frame or T-Bar grid – see
Figure 2.
D. Attach ductwork to the neck of the diffuser if using
flexible duct. This can be done from an adjacent
ceiling grid if T-Bar application is used – see Figure 3.

Baffle Installation for Cone Diffusers
This section applies to the accessory installation of baffles for Greenheck models XG-5700 and XG-5800 only.
Baffles are used to block air from being distributed through one side of a diffuser. Multiple baffles can be used on the
same diffuser to reach the desired direction of airflow.
A. Place the diffuser face up on a flat surface. Locate
the plastic latches on each leg of the inner core. Twist
the latches and remove the core from the backpan –
see Figure 4.

same diffuser to reach the desired direction of airflow.
A. Place the diffuser face up on a flat surface. Locate the plastic latches on each leg of the inner plaque face. Twist
the latches and remove the plaque face from the backpan – see Figure 8.
B. Place the plaque face with legs facing upwards. Locate the Blank-Off and two S-clips provided with the Blank-Off.
Install the S-clips onto the Blank-Off – see Figure 9.

Our Commitment
General Maintenance
Diffusers are basically maintenance free. Most Greenheck diffuser models have removable faces to allow for cleaning
of dust buildup within the duct or on the internal damper when included. The face of most diffusers can be cleaned
with water and mild detergent if dirt and dust begin to build up.
