They are intended for use in automatic sprinkler systems designed in accor- dance with standard installation rules (e.g., NFPA 13) for the protection of light hazards up to a maximum cover- age area of 400 ft' (37,2 m2), as compared to the maximum coverage area of 225 ft2 (20,9 m2) for standard coverage sprinklers. The recessed version of the Central Model BV-20 QR ECLH, intended for use in areas with a finished ceiling, uses a two-piece Model ELO Recessed Escutcheon. The Model ELO Recessed Escutcheon provides up to 3/4 inch (19,1 mm) of total adjustment from the flush pendent position. The adjustment provided by these Recessed Escutch- eons reduces the accuracy to which the fixed pipe drops to the sprinklers must be cut. 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 & flow water. WARNING The Model BV-20 QR ECLH Pendent & Rec. Pendent 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 The owner is responsible for maintain- ing their fire protection system and devices in proper operating condition. The installing contractor or sprinkler manufacturer should be contacted relative to any questions. Technical Data Sprinkler Identification Number SIN 04232 Approvals UL & ULC Listed.

The minimum lateral spacing between the BV-20 OR ECLH Pendent and Recessed Pendent Sprinkers to prevent cold soldering, is 8 feet (2,4 m). The Model BV-20 OR Sprinklers can be used with any metalic flush or extended escutcheon, provided the maximum ceiling to top of sprinkler deflector dimension specified in NFPA 13 is maintained. For recessed applications, only the Model ELO Recessed Escutcheon Assemblies may be used. 13 Installation The Model BV-20 OR ELCH 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 3/4 inch NPTsprinkier joint should be obtained with a torque of 10 to 20 ft.lbs. (13,4 to 26,8 Nm). A maximum of 30 ft.!bs. (40,7 Nm) of torque is to be used to install 3/4 inch NPT sprinklers. Higher levels of torque may distort the sprinkler inlet with consequent leakage or impairment of the sprinkler. Do not attempt to compensate for insufficient adjustment in an Escutcheon Plate by under- or over-tightening the Sprinkler. Readjust the position of the sprinkler fitting to suit. Step 1. Pendent sprinklers must be installed only in the pendent position. The deflector is to be parallel to the ceiling, roof, or mounting surface, as applicable. Step 2. After installing the ELO support cup (or other escutch- eon, as applicable) over the sprinkler pipe threads & with pipe thread sealant applied to the pipe threads, hand tighten the sprinkler into the sprinkler fitting. Step 3. Wrench tighten the sprinkler using only the following wrenches: BV-20 OR Pend - W-Type 3 (Ref. Fig. 3) BV-20 OR Rec. Pend - ELO Offset (Ref. Fig. 4) Wrenches are to be applied to the sprinkler wrench flats (Ref. Fig. 2) only. a Care & Maintenance The Model BV-20 OR ECLH Sprinklers must be main- tained and serviced in accordance with the following instructions. NOTES Absence of an escutcheon which is used to cover a clearance hole, may delay the time to operation in a fire situation. Before closing a fire protection system main control valve for maintenance work on the fire protection system it controls, permission to shut down the affected fire protec- tion systems must be obtained from the proper authorities. All personnel who may be affected by this action must be notified. 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 their temperatures 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 replaced. Sprinklers that have been exposed to corrosive products of combustion, but have not operated, should be replaced if they cannot 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. Installation Sec- tion). The owner is responsible for the inspection, testing, and maintenance of their fire protection system and devices in compliance with this document, as well as with the appli- cable standards of the National Fire Protection Association (e.g., NFPA 23), in addition to the standards of any other authorities having jurisdiction. The installing contractor or sprinkler manufacturer should be contacted relative to any questions. It is recommended that automatic sprinkler systems be inspected, tested, and maintained by a qualified Inspection Service.
