Horizontal Sidewall & Recessed Horizontal Sidewall
Glass Bulb Automatic Sprinkler
General
Description
The Central Model BVR, 5.4 K-factor
Residential Horizontal Sidewall &
Recessed Horizontal Sidewall Sprinklers
are decorative glass bulb sprinklers
designed for use in residential occupan-
cies such as homes, apartments,
dormitories, and hotels.
They are to be used in wet pipe residential
sprinkler systems for one- and two-family
dwellings and mobile homes per NFPA
13D; wet pipe residential sprinkler
systems for residential occupancies up to
and including four stories in height per
NFPA 13R; or, wet pipe sprinkler systems
for the residential portions of any occu-
pancy per NFPA 13.
The recessed version of the Model BVR
Residential Horizontal Sidewall Sprinkler is
obtained by utilizing the Model BVR
Horizontal Sidewall Sprinkler in combina-
tion with the Model BV Res./QR Re-
cessed Escutcheon Assembly. The
recessed version of the Central Model
BVR using a Model BV Res./QR Re-
cessed Escutcheon provides up to 3/8
inch (9,5 mm) of total adjustment from the
flush Horizontal Sidewall position.
Operation: The glass bulb contains a fluid
which expands when exposed to heat.
When the rated temperature is reached,
the fluid expands sufficiently to shatter the
glass bulb, which then allows the sprinkler
to activate and flow water.
WARNING
The BVR Residential Horizontal
Sidewall Sprinklers described herein
must be installed and maintained in
compliance with this document, as well
as with the applicable standards of the
National Fire Protection Association, in
addition to the standards of any other
authorities having jurisdiction. Failure
to do so may impair the integrity of
these devices.
Because of the above cited stipulations
and the varied nature of residential
type architecture, there will be some
compartment designs which cannot be

Design
Criteria (Cont.) Installation
The Central Model BVR Horizontal
Sidewall Sprinklers must be installed in
accordance with the following instructions:
NOTES
Do not install any bulb type sprinkler if the
bulb is cracked or there is a loss of liquid
from the bulb. With the sprinkler held
horizontally, a small air bubble with an
approximate diameter of 1/16 inch should
be present.
A leak tight 1/2 inch NPT sprinkler joint
should be obtained with a torque of 7 to 14
ft.lbs. (9,5 to 19,0 Nm). A maximum of 21
ft.lbs. (28,5 Nm) of torque is to be used to
install 1/2 inch NPT sprinklers. Higher
levels of torque may distort the sprinkler
inlet with consequent leakage or impair-
ment of the sprinkler.
Step 1. The sprinkler must only be
installed in the sidewall position with the
centerline of the sprinkler parallel to the
ceiling and perpendicular to the wall. The
top of the deflector is to be positioned
towards the ceiling.
Step 2. After installing the BV Res./QR
Recessed Support Cup (or other accept-
able escutcheon, as applicable) over the
sprinkler pipe threads and with pipe thread
sealant applied to the pipe threads, hand
TIA 99-1 (Tentative Interim Ammendment)
with an effective date of May 22, 2000
states that the minimum required
discharge from each of the "design
sprinklers" for systems designed to NFPA
13 must be calculated based on delivering
a minimum design density of 0.1 gpm/sq.
ft. for each of the listed coverage areas
shown in Table 1, Table 2, or Table 3.
Consult the authority having jurisdiction
regarding the application of this TIA to the
currently adopted NFPA 13.
Model BVR Residential Horizontal
Sidewall and Recessed Horizontal
Sidewall Sprinklers must be installed using
the obstruction and minimum distance
between sprinkler criteria for extended
coverage sidewall sprinklers found the
current edition of NFPA 13.
NOTES
Residential Fire Sprinkler Systems
should only be designed and installed
by those competent and completely
familiar with automatic sprinkler
system design, installation procedures,
and techniques.
The sprinkler must be secured in
position by firmly fastening the
sprinkler system piping to the
structure. If the sprinkler is not
properly secured in position, reaction
forces resulting from sprinkler
operation could alter its orientation and
its water distribution pattern. The
sprinkler escutcheon cannot be used
to hold the sprinkler in position.
Several criteria may apply to the
installation and usage of each
sprinkler. Consequently, it is
recommended that the sprinkler
system designer review and develop a
working understanding of the
complete list of criteria prior to
initiating the design of the sprinkler
system.
Questions concerning sprinkler
installation and usage criteria, which
are not covered by the following
instructions, should be submitted to
Central Sprinkler. Include sketches and
technical details as appropriate.
In some instances, the requirements of
this document may concern
specifications which are more
stringent and which take precedence
over those specified in NFPA 13, NFPA
13D, NFPA 13R, or by the authority
having jurisdiction.
tighten the sprinkler into the sprinkler
fitting.
Step 3. Wrench tighten the sprinkler using
only a BV Sprinkler Wrench (1099). The
wrench recess of the BV Sprinkler Wrench
is to be applied to the sprinkler wrench
flats (Ref Figure 3).
Step 4. For Recessed Sidewall Sprinkler
Applications, a Protective Cap is available
which helps to prevent damage to the
sprinkler during ceiling/wall installation
and/or during application of the finish
coating of the ceiling/wall. Place the
Protective Cap over the Recessed
Support Cup and push it sideways until it
bottoms out against the sprinkler deflector.
NOTE
As long as the Protective Cap remains in
place, the system is considered to be "Out
of Service"
Step 5. After the ceiling/wall has been
completed , remove and discard the
Protective Cap. If the Sprinkler has been
damaged, replace the entire Sprinkler
assembly. Do not attempt to modify or
repair a damaged sprinkler.
Step 6. Push the outer ring of the
Recessed Escutcheon over the Re-
cessed Support Cup. If the Recessed
Escutcheon cannot be engaged with the
Support Cup or the Recessed Escutcheon
cannot be engaged sufficiently to contact
the wall, the Sprinkler Fitting must be
repositioned.

replaced. Sprinklers that have been
exposed to corrosive products of
combustion, but have not operated,
should be completely cleaned by
wiping the sprinkler with a cloth or by
brushing it with a soft bristle brush.
Care must be exercised to avoid
damage - before, during, and after
installation. Sprinklers damaged by
dropping, striking, wrench twist/
slippage, or the like, must be re-
placed. Also, replace any sprinkler
that has a cracked bulb or that has
lost liquid from its bulb (Ref. Installa-
tion Section).
The Central Model BVR Horizontal
Sidewall Sprinklers must only be
replaced with sidewall sprinklers which
are listed for residential fire protection
service and which have the same
nominal K-factor, the same coverage
area, and the same or lower flow ratings
(as indicated under "Design Criteria").
When remodeling, such as by adding
false beams or light fixtures or changing
the location of compartment walls, first
verify that the new construction will not
violate the installation requirements
stated under WARNINGS. Alter the new
construction and/or the sprinkler system
to suit the requirements of this docu-
ment.
The owner is responsible for the
inspection, testing, and maintenance
of their fire protection system and

The Central Model BVR Horizontal
Sidewall Sprinklers must be maintained
and serviced in accordance with the
following instructions:
NOTES
Wet pipe sprinkler systems must be
maintained at a minimum tempera-
ture of 40 ° F/4 ° C to prevent freezing
and bursting of the pipe and/or
sprinklers.
Automatic sprinklers are not to be
tested with a heat source. Operation
of the heat responsive element (bulb)
can result.
Absence of an Escutcheon Plate may
delay the time to sprinkler operation
in a fire situation.
Before closing a fire protection
system main control valve for
maintenance work on the fire
protection system which it controls,
permission to shut down the affected
fire protection system must be
obtained from the proper authorities
and all personnel who may be
affected by this action must be
notified.
Do NOT enclose sprinklers within
drapes, curtains, or valances.
Do NOT hang anything from the
sprinklers.
Do NOT cleanse the sprinklers with
soap and water, detergents, ammo-
nia, cleaning fluids, or other chemi-
cals. Remove dust, lint, cobwebs,
cocoons, insects, and larvae by
gently brushing with a feather duster
or gently vacuuming with a soft
bristle (i.e., dusting) brush attach-
ment.
Exercise suitable safety precautions
in the use and storage of highly
flammable materials. The rapid rate
of fire development and spread of
which can be caused by such
materials can reduce the ability of
the sprinkler system to aid in the
control of a fire in which they are
involved.
Sprinklers which are found to be
leaking or exhibiting visible signs of
corrosion must be replaced.
Automatic sprinklers must never be
shipped or stored where its tempera-
ture will exceed 100°F/38°C and they
must never be painted, plated, coated,
or otherwise altered after leaving the
factory. Modified sprinklers must be
