Duct Drains
Drains are used to provide a point at which low points in the duct system can be
drained. Condensation and low lying water left over from duct cleaning can be
drained easily with the installation of the ball valve drain. Drains are designed to
aid in duct cleaning and can be used to drain grease into an approved grease
collection reservoir. Drains can be hard piped to an approved grease collection
reservoir, remove the cap and connect to the 1-1/2” NPT threads. See Fig. 4. for
details.
Grease Manifold Tee
The grease manifold tee is used to provide access for cleanout to comply with
NFPA 96 requirements. It is equipped with an internal blank that acts as a grease
dam and gasket. The access port is then closed with a cleanout cap or tee cap.
The location of the access port in the tee is dependent on the orientation of the tee
in the final installation. Access port location is coded as Position 1, 2, 3, 4 see
Fig. 5. Access ports are never located where grease can build up and fall out
once the cleanout cap is removed.
