Product Description

The Reliable Model G4 XLO-QR ECLH/ECOH Concealed

sprinkler is an Extended Coverage Sprinkler for use in Light

Hazard and Ordinary Hazard occupancies with a coverage

area of up to 400 square feet (37.2 m2) per sprinkler.

The use of extended coverage sprinklers can provide lower

installation costs by requiring fewer sprinklers, less piping and

reduced labor. The larger K-factor 11.2 (160 metric) provides

for reduced pressures to achieve the required flow compared

with smaller K-factor sprinklers.

The G4 XLO-QR ECLH/ECOH can eliminate the need for

precise cutting of drop nipples. The Thread-on/Thread-off cov-

er plate assembly provides up to 1/2” (13 mm) of adjustment

to allow the cover to fit accurately against the ceiling. The fire

protection system need not be shut down when adjusting or

removing the Thread-on/Thread-off cover plate assembly.

G4XLO-QR ECLH/ECOH sprinklers are to be installed ac-

cording to the design criteria shown in this Bulletin, NFPA 13,

and all other local codes and ordinances. Flows and pres-

sures, as shown in the Flow Requirements chart on page 2

of this Bulletin, must be selected based on the spacing and

hazard classifications.

The following criteria also apply:

• Minimum sprinkler spacing is 9 ft (2.75 m).

• Sprinklers have a minimum flow requirement for each

spacing as shown in the Flow Requirements chart on

page 2.

• Sprinklers are only to be used in systems hydraulically

designed per NFPA 13.

• Deflector to commodity clearance shall be a minimum

of 18 inches (457 mm).

• Sprinklers shall be installed in unobstructed construc-

tion as defined in NFPA 13.

• Sprinklers can be installed under a sloping ceiling not

exceeding 2 inches (50.8 mm) of rise in 12 inches

Installation

Do not install the MODEL G4

XLO-QR ECLH/ECOH in ceilings

which have positive pressure in

the space above. After installa-

tion, inspect all sprinklers to en-

sure that both the gap between

the cover plate and ceiling and

the 4 drive slots in the cup are

open and free from any air flow

impediment.

After a 25

8” (67 mm) diam-

eter hole is cut in the ceiling,

Maintenance

Model G4XLO-QR ECLH/ECOH sprinklers should be in-

spected and maintained in accordance with NFPA 25. Do

not clean sprinklers with soap and water, ammonia or any

other cleaning fluids. Remove dust by using a soft brush

or gentle vacuuming. Replace any sprinkler or cover plate

assembly, which has been painted (other than factory ap-

plied) or damaged in any way. A stock of spare sprinklers

should be maintained to allow quick replacement of dam-

aged or operated sprinklers. Prior to installation, sprin-

klers should be maintained in their original cartons and

packaging until used to minimize the potential for damage

to sprinklers that would cause improper operation or non-

operation. Once operated automatic sprinklers and cover

plates cannot be reassembled and reused. New sprin-

klers of the same size, type and temperature rating must

be installed. A cabinet of replacement sprinklers should

be provided for this purpose.

XLO EC Wrench

the sprinkler is to be installed with the Model XLO EC

Wrench. When installing a sprinkler, the wrench is first

positioned into the sprinkler/cup assembly until two

wrench tangs fully engage drive slots in the top of the

cup. The sprinkler is then tightened into the pipe fitting.

When inserting or removing the wrench from the sprin-

kler/cup assembly care should be taken to prevent dam-

age to the sprinkler. DO NOT WRENCH ON ANY OTHER

PART OF THE SPRINKLER/CUP ASSEMBLY.

A protective cap is provided to protect the drop down

deflector from damage which could occur during con-

struction before the cover plate is installed. The cap is

factory installed inside the sprinkler cup. Remove the

cap to install the sprinkler, then replace the cap until the

cover plate is installed.

THE MODEL G4 XLO-QR ECLH/ECOH SPRINKLER

MUST BE INSTALLED ONLY WITH A 135°F RATED

COVER PLATE WHICH HAS BEEN LISTED WITH THE

SPRINKLER.
