Product Description

Reliable Model G Series sprinklers are standard-response

standard spray automatic sprinklers using a solder capsule

thermal element. The solder is captured in the cylinder of the

capsule by a stainless steel ball. When the solder melts, the ball

moves into the cylinder allowing the thermal element to fall away

from the sprinkler. When this occurs, the compressed strut and

lever spring free from the sprinkler. System pressure then clears

the waterway of all operating parts allowing the deflector to

evenly distribute water.

Pendent and horizontal sidewall sprinklers may be installed

exposed or surface mounted using escutcheons such as the

Reliable Models B, C, or HB (reference Technical Bulletin 204).

When installed recessed, the Model G Series sprinklers are

specically listed with and may only be installed with listed

Reliable escutcheons. Refer to the technical information on the

following pages for specic listings for recessed installations and

Figures 6 and 7 for dimensional information.

Maintenance

Reliable Model G series sprinklers should be inspected and the

sprinkler system maintained in accordance with NFPA 25, as well

as the requirements of any authorities having jurisdiction.

Prior to installation, sprinklers should remain in the original

cartons and packaging until used. This will minimize the potential

for damage to sprinklers that could cause improper operation or

non-operation.

Do not clean sprinklers with soap and water, ammonia liquid or

any other cleaning fluids. Remove dust by gentle vacuuming

without touching the sprinkler.

Replace any sprinkler which has been painted (other than factory

applied). A stock of spare sprinklers should be maintained to

allow quick replacement of damaged or operated sprinklers.

Failure to properly maintain sprinklers may result in inadvertent

operation or non-operation during a re event.

Installation

Model G Series sprinklers must be installed in accordance with

NFPA 13 and the requirements of all applicable authorities having

jurisdiction

Model G Series sprinklers must be installed with the Reliable

sprinkler installation wrench identied in this Bulletin. Any other

wrench may damage the sprinkler. A leak tight sprinkler joint

can be obtained with a torque of 8 to 18 lb-ft (11 - 24 N.m) for

1/2” sprinklers and a torque of 14-20 lb-ft (19 - 27 N.m) for 3/4”

sprinklers after applying appropriate thread sealant.

Do not tighten sprinklers over the maximum recommended

installation torque. Exceeding the maximum recommended

installation torque may cause leakage or impairment of the

sprinkler.
