General Instructions
The Model TN-17 Nozzle is to be ori-
ented horizontally with the plane
created by its two frame arms paral-
lel with the ceiling or parallel with the
finished grade, in the case of a non-flat
ceiling.
Step 1.
Ensure all piping components
are properly assembled as shown in
Figure 3 prior to installing the Model
TN-17 Nozzle.
Step 2.
With pipe-thread sealant
applied to the nozzle threads, hand-
tighten the Model TN-17 Nozzle into
the Reducer.
Step 3.
The Model TN-17 Nozzle must
be tightened using only the W-Type 21
Sprinkler Wrench as shown in Figure 2.
Fully engage the nozzle wrench flats as

A leak-tight 3/4 in. NPT or ISO 7-R
3/4 sprinkler joint should be obtained
by applying a minimum-to-maximum
torque of 20 to 30 ft-lb (26,8 to 40,2
N
∙
m). Higher levels of torque can
distort the nozzle inlet with consequent
leakage or impairment of the nozzle.
Ensure the markings on the deflector
face towards the ceiling.
