The Sloan GEM • 2
®
is a piston type Flushometer which incorporates many of
the same quality features found in Sloan Diaphragm Flushometers. The GEM •
2 provides outstanding water saving capabilities by precisely metering every
flush. Additionally, the GEM • 2 incorporates a filtered by-pass which ensures
consistent flushing even undersevere water conditions.
TheGEM•2Flushometeris designedforeasyinstallationandmaintenanceand
comes complete with an ADA compliant metal oscillating Non-Hold-Open lever
actuator, Bak-Chek
®
control stop, adjustable tailpiece, vacuum breaker flush
connection, spudcoupling,and wall andspud flanges.
The following instructions will serve as a guide when installing the Sloan GEM •
2 Flushometer. As always, good safety practices and care are recommended
when installing your new Flushometer. If further assistance is required, contact

PRIOR TO INSTALLATION
Prior to installing the Sloan GEM •2 Flushometer, install the items listed below
as illustratedin Figure 1.
• Closet/urinal fixture
• Drain line
• Water supplyline
Important:
• ALL PLUMBING IS TO BE INSTALLED IN ACCORDANCE WITH
APPLICABLE CODES ANDREGULATIONS.
• WATER SUPPLY LINES MUST BE SIZED TO PROVIDE AN ADEQUATE
VOLUME OF WATER FOR EACH FIXTURE.
• FLUSH ALLWATERLINES PRIOR TO MAKING CONNECTIONS.
TheSloanGEM •2
®
isdesignedto operatewith10 to100psi(69 to689 kPa)of
water pressure. THE MINIMUM PRESSURE REQUIRED TO THE VALVE IS
DETERMINED BY THE TYPE OF FIXTURE SELECTED. Consult fixture
manufacturer forminimum pressurerequirements.
Most Low Consumption water closets (1.6 gallon/6 liter) require a minimum
flowing pressureof 25 psi (172kPa).
Protect the Chrome or Special finish of this Flushometer — DO NOT USE
TOOTHED TOOLS TO INSTALL OR SERVICE THE VALVE. Also, see “Care
and Cleaning” section of thismanual.
IMPORTANT: WITH THE EXCEPTION OFCONTROL STOPINLET, DONOT
USE PIPE SEALANT OR PLUMBING GREASE ON ANY VALVE
COMPONENT OR COUPLING!
TOOLS REQUIRED FOR INSTALLATION
• Slotted screwdriver
• Sloan A-50“Super-Wrench™” or smooth jawed spud wrench
INSTALLATION
Step 1 - Control Stop Installation (Figure 2)

For Sweat Solder applications, refer to the following instructions and
Figure 3:
A. Measure distance fromfinishedwall tocenterlineof Fixture Spud. Cutwater
supply pipe 1-1/4" (32 mm) shorter than this measurement. Chamfer O.D.
and I.D. of water supply pipe.
B. SlideThreadedAdapterontowatersupplypipeuntilendofpiperestsagainst
shoulder of Adapter. Sweat solder Adapter towater supply pipe.
C. Determinelengthof CoveringTubeby measuringdistancefrom finishedwall

to this length.
D. SlideCoveringTubeontowatersupplypipe.SlideWallFlangeoverCovering

Control Stop to the water supply line with the
outlet positioned as required.
Step 2 - Install Vacuum Breaker Flush Connection (Figure 4)
Slide the Spud Coupling, Nylon Slip Gasket, Rubber Gasket and Spud Flange
over the Vacuum BreakerTube and insert tube into Fixture Spud. Hand tighten
Spud Coupling onto Fixture Spud.
On valves furnished less vacuum breaker (xyv variation), connect flush tube to
the bottom of thevalve using the Slip Gasketsupplied.
Step 3 - Install Flushometer

Important Note: Use a
Sloan A-50 “Super-
Wrench™” or smooth jawed
spud wrench to secure all
couplings. This will eliminate damage to chrome or special finish that normally
occurs whenslip-joint pliers, pipe wrenches or other “toothed” tools are used.
Step 4 - Install Handle (Figure 6)
Install HandleAssemblyto ValveBody and tighten securely.
Step 5 - Flush Out Supply Line (Figure 7)
Shut off Control Stop and remove Flushometer Cover. Lift out the Piston
Assembly. Install Flushometer Cover wrench tight andopen Control Stop. Turn
on water supply to flush line of any debris orsediment.

Important: The Sloan GEM•2
®
Flushometer isengineered for quiet operation.
Excessivewaterflowcreatesnoise, whiletoolittlewaterflow maynotsatisfy the
needs of the fixture. Proper adjustment is madewhen:
1. Theplumbingfixture iscleansedafter eachflushwithoutsplashingwaterout
from the lip.
2. A quiet flushing cycle isachieved.
After adjustment: Wrench Tighten Control Stop to EliminateVandalism.
CAREANDCLEANINGOFCHROMEANDSPECIALFINISHES
DO NOT useabrasiveor chemical cleanerstoclean Flushometers asthey may
dull the luster and attack the chrome or special decorative finishes. Use ONLY
soap and water, then wipe drywith clean cloth or towel.
Whilecleaningthe bathroomtile, theFlushometer should beprotectedfromany
splattering of cleaner. Acidsand cleaning fluids can discolor or remove chrome
plating.

I. Flushometer does not function.
A. ControlStopor MainValveisClosed.Open ControlStopor MainValve.
B. Handle Assembly is worn. Install Sloan Handle Repair Kit (G-50-A) or
replace handle.
C. Relief Valve is worn andsticking inUP position. Replace Piston.
II. Insufficient volume of water to adequately siphon fixture.
A. Control Stopnot open enough. Adjust Control Stop fordesired delivery
of water.
B. Urinal Piston Parts inside a Closet Flushometer. Replace Piston Parts
with proper Closet Piston.
C. Low Consumption Flushometer installed on a non-Low Consumption
fixture. Replacewith proper Piston Kit.
D. Inadequate volume or pressure at supply. Increase water pressure or
supply (flow)to Flushometer.Consult Factory for assistance.
III. Length of flush is too short (Short Flushing) or Flushometer
closes off immediately.
A. Piston Assembly is nothand-tight. Screwthe assembly hand-tight.
B. Enlarged By-passorifice from corrosionor damage. Install NEWInside
Piston Kitto correct problemand update Flushometer.
C. Urinal Piston in Closet Flushometer. ReplacePistonwith proper Closet
Piston.
D. Low Consumption Piston installed in non-Low Consumption fixture.
Replace Piston with properCloset Piston.
E. Handle Assembly is worn.Install Handle Repair Kit G-50-A.
IV. Length of flushistoolong(Long Flushing)or failstocloseoff.
A. Piston is not seating properly or By-pass orifice is clogged because of
foreign material, or By-pass orifice is closed by an invisible gelatinous
film from “over-treated” water.
Disassemble the working parts and wash thoroughly. NOTE: SIZE OF
THE ORIFICE INTHE BY-PASS ISOF UTMOST IMPORTANCE FOR
THEPROPERMETERINGOF WATERINTO THEUPPERCHAMBER
OF THE FLUSHOMETER. DO NOT ENLARGE OR DAMAGE THIS
ORIFICE. REPLACE PISTON IF CLEANING DOES NOT CORRECT
PROBLEM.
B. Line pressure has dropped and is not sufficient to force Relief Valveto
seat. Shut off all control stops until pressure has been restored, then
open them again.
C. 3.5 gpf Closet Piston hasbeen used ina 1 or 1.5 gpfUrinal or ona 1.6
