sprinkler waterway must be located 4-1/2 to 12-1/2
inches (114,3 to 317,5 mm) below the ceiling (Ref. Figure
2).
Only the Institutional Escutcheons shown in Figure 3 can
be utilized with the StarMax S102, and only a maximum
of three Spacers (#1752) can be utilized with Style B1 or
D Institutional Escutcheons when horizontal adjustment is
desired.
NOTES
The Sprinkler Body must not extend beyond the Institu-
tional Escutcheon (Ref. Figure 5). Otherwise the tamper
resistant design of the StarMax will be compromised.
Consequently, a maximum of three Spacers can only be
utilized with the Style B1 or D Institutional Escutcheons.
#1752 Spacers cannot to be utilized with the Style E
Institutional Escutcheons.
Integrity of the tamper resistant design of the Institutional
Escutcheon is dependent on the piping installation de-
sign. When installed properly, the Institutional Escutch-
eon is held fast to the mounting surface by the tightening
of the sprinkler assembly into the sprinkler fitting. In order
to accomplish a proper installation, the sprinkler fitting
must be properly located with respect to distance from
the face of the sprinkler fitting to the face of the mounting
surface (Ref. Figure 3); the sprinkler fitting being rigidly
secured and held immobile; and, the centerline of the
sprinkler fitting being perpendicular to the mounting sur-
face to assure that the escutcheon sits squarely against
the mounting surface around the entire perimeter of the
Institutional Escutcheon. Figure 2 illustrates a typical in-
stallation that can be utilized to help adjust the location
of the sprinkler fitting; to help assure immobility of the
sprinkler fitting; and, to help maintain perpendicularity of
the sprinkler fitting to the mounting surface.
