Product Description
The Reliable Model HL22 is an Early Suppression Fast
Response (ESFR) Sprinkler with a nominal K-Factor of 22.4 (320
metric). This sprinkler is designed to respond quickly to growing
fires with a high volume of water discharge to “suppress” rather
than “control” fires.
FM Global classifies the Model HL22 as a quick-response
sprinkler, storage and non-storage, when the sprinkler is used
in accordance with FM Global Property Loss Prevention Data
Sheets.
The Model HL22 sprinkler utilizes a levered fusible alloy solder
link in either 165 °F (74 °C) or 212 °F (100 °C) temperature
ratings. Model HL22 sprinklers are UL Listed for compliance
with UL 1767 and have successfully completed high clearance
tests for rack storage.
Application and Installation
The HL22 ESFR sprinkler is intended for installation in
accordance with NFPA 13 and Factory Mutual (FM) Loss
Prevention Data Sheets 2-0 and 8-9, as well as the requirements
of any Authorities Having Jurisdiction. See Table 1 for information
on NFPA and FM Global design criteria for the Model HL22
sprinkler.
Installation Criteria
The following general guidelines are provided for information
only. NFPA and, where applicable, FM Global standards shall be
consulted for complete design and installation criteria.
Sprinkler Position: Pendent, align frame arms with the
pipe. Deflectors should be parallel with the ceiling or roof.
System Type: Wet Pipe Systems Only.
Maximum area of coverage: 100 ft2(9.3 m2), greater
coverage area are allowable in some cases.
Minimum area of coverage: 64 ft2(5.8 m2).
Model HL22 Sprinkler
Maximum slope ceiling: 2/12 pitch (9.5°).
Maximum spacing: 12 ft (3.7 m) for building heights up
to 30 ft (9.1 m) and 10 ft (3.1 m) for building heights greater
than 30 ft (9.1 m), except where otherwise permitted.
Minimum spacing: 8 ft (2.4 m).
Deflector distance from walls: At least 4" (102 mm) from
walls, and no more than one-half the allowable distance
permitted between sprinklers.
Deflector to Top of Storage: At least 36" (914 mm).
Deflector to ceiling Distance: 6-18" (152-457 mm)
per NFPA 13; 6-14" (152-356 mm) when using UL Listed
Special Application criteria for ceilings up to 48 ft (14.6 m).
Center Line of Thermal Sensing Element To Ceiling
Distance (FM Only): Max. 17" (425 mm); Min. 2" (50 mm)
with smooth ceilings; Min. 4" (100 mm) with non-smooth
ceilings.

Listings and Approvals
1. Listed by Underwriters Laboratories, Inc. and UL certified
for Canada (cULus).
2. FM Approved as a quick-response, storage and non-
storage, sprinkler (FM).

Specific Application Listing
In addition to design criteria permitted by NFPA 13, the Model
HL22 also has the following Specific Application Listing from UL:
Sprinkler: Model HL22 in 212 °F (100 °C) only
Maximum Ceiling Height: 48 ft (14.6 m)
Maximum Storage Height: 43 ft (13.1 m)
Minimum Aisle Width: 8 ft (2.44 m)
Permitted Commodities: Class I - IV commodities, encap-
sulated or nonencapsulated, and Cartoned Group A Unex-
panded plastics. Permitted Storage Arrangements: Single-
and double-row rack storage (no open top containers or
solid shelves) and palletized and solid pile storage (no open
top containers or solid shelves).
Minimum System Operating Pressure: 55 psi (3.79 bar).
Installation and Obstruction Criteria: Same as for
K25.2 ESFR sprinklers, but with a maximum deflector to
ceiling distance of 14" (356 mm)
Maintenance
The HL22 Sprinkler should be inspected and the sprinkler
system 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 that has been painted (other than factory
applied) or damaged in any way. A stock of spare sprinklers
should be maintained to allow quick replacement of damaged
or operated sprinklers. Prior to installation, sprinklers should be
maintained in the original cartons and packaging until used. This
will minimize the potential for damage to sprinklers that would
cause improper operation or non-operation.
