ChamFlex® Fire Retardant Hose Assemblies Installation Instructions
ChamFlex® Fire Retardant Hose Assemblies
Installation Instructions
A) All applications should be checked to ensure that the proper hose assembly lengths are being installed:

Hose assemblies should not be installed in a “stretched” (taut) fashion. Some expansion and contraction of the
hose assembly can occur due to temperature variation, system pressures, and system cycling (see Figure #1).

All hose assemblies should be routed properly to avoid contact with other surfaces that could possibly cause
“chafing” (abrasion of the wire braided reinforcement).

The use of elbows and adapters should be considered to relieve hose “strain” (see Figure #2). Do not use any
plastic fittings or adapters.
Hose assemblies should not be “bent” past the minimum bend radius requirements listed in the chart below.
Hose assemblies showing evidence of “kinking” (being bent beyond the recommended bend radius) should not
be installed (see Figure #3).

B) All hose assemblies should be installed in the following fashion so that no “twisting” occurs:

Solid male pipe thread (NPT) ends should be installed first unless they are being connected to a “swivel” female
(NPT). The entire hose assembly must rotate during the tightening of this connection in order to avoid hose tube
damage.

The flared adapter on the “union” (female swivel) end should be removed with the male pipe (NPT) end of the
adapter connected to the appropriate port first.
CAUTION: Thread sealant or thread tape should not be used on “flared” connections. Additional thread sealant or
thread tape should not be applied to male pipe thread (NPT) ends where factory installed thread sealant is already
present.

The last step is to reconnect the flared swivel female coupling to the flared end of the adapter in a manner that
ensures that the hose assembly is not twisted (see Figure #4).

Model AM Flo-Setter Balance and Commissioning Valve
Description: Bell & Gossett Model AM Flo-Setter Balance & Commissioning Valves are precision engineered valves used in heating and cooling systems for the distribution of flow in various sections of the system. The dynamic balancing and commissioning valve ensures easy and reliable balancing of the system, regardless of any fluctuations in the differential pressure of the system. The Bell & Gossett Circuit Sentry Flo-Setter limits the maximum flow in the system and can be sued in both variable and
constant flow systems. The clear scale on the lockable handle ensures that flow setting is simple and user friendly while the integral P/T ports allow verification of pressure.
Installation Instructions:
Circuit Sentry Flo-Setter Balance & Commissioning valves are uni-directional valves and can be installed in most altitudes; however, they should be installed in a position
to facilitate the ease of balancing the system. Be sure to install the Circuit Sentry Flo-Setter with the arrow pointing in the direction of flow.
Circuit Balance valves with NPT Connections:
Apply pipe compound conservatively to male connecting fittings only. Check connection for leaks.
CAUTION: The use of Teflon® impregnated pipe compound and Teflon® tape on threads provides lubricity. Care should be taken to prevent over tightening of the
valves which may damage the Circuit Sentry Flo-Setter.
CAUTION: Do not use pipe dope where thread sealant is pre-applied when connecting valves to ChamFlex/All Metal SS Braided Hose Assemblies.
Operation Instructions:
How to use Bell & Gossett Circuit Sentry Flo-Setter Balance & Commissioning Valves for Pre-Set Flow Balancing:
The Circuit Sentry Flo-Setter Balance & Commissioning Valve is easily set, and the pre-setting is read on the scale. The flow rate of the valve can be determined from the
flow rate graphs for the valve dimension in question. See the flow rate graphs of the valve in the FLOW CURVE BOOK (G10092) or Submittal (A-609.22 or A-611) for
further information about the adjustment setting. Select the appropriate size Circuit Sentry Flo-Setter Balance & Commissioning Valve (normally line size) for the required
GPM.
Please note: The scale is for the adjustment of flow. If you want to close the branch line, use an isolation ball valve in conjunction with the Circuit Sentry Flo-Setter.
The handle can be locked after adjustment. Remove the B&G logo cap and tighten with 5mm hexagonal key.
How to use Bell & Gossett Circuit Sentry Flo-Setter to Proportional Balance System:
The system is easily balanced by adjusting the pump according to the required differential pressure across the critical valve. When the differential pressure is available the
system will automatically be balanced.
How to use Bell & Gossett Circuit Sentry Flo-Setter Balance & Commissioning valves as Flow Meters:
The flow through the valve can be identified by measuring the differential pressure
p across the valve. If the measured differential pressure is above the minimum
p, the flow is the one stated on the graph for the valve. If the measured differential pressure is below the minimum
p, the flow can be found by using the formula below.
Q = Cv x
P

Operate the Valve:
WARNING:

Burn hazard. Water temperature higher than 110oF (38oC) can be dangerous. Take all necessary precautions to prevent water or steam leakage.

Hot water leakage can occur from readout valves during probe insertion and during hookup of readout kit. Follow the safety instructions supplied
with readout probes and readout kits.
Caution: Avoid pipe strain. This can cause breakage and water loss over time.
1.
Ensure that the valve is fully open.
2.
Using Bell & Gossett Model RP250-B Readout Probes, attach a Bell & Gossett differential pressure readout kit to the readout valves on the desired
valve.
3.
Measure the pressure differential across the readout valves (P/T ports) in the valve body, or in the valve body and through the valve handle. Confirm that the valve obtained is greater that the minimum value indicated in the valve submittal. If it is not, then investigate the causes and if
necessary, report to the designer.
4.
Adjust the flow setting dial to the specified design flow rate. Lock the dial-in position and record settings.
5.
Repeat the process for all valves on the branch.
6.
Measure the flow rate indicated at the flow measurement device on the branch. Confirm that the value recorded is equal to the sum of the flows
that are set at downstream valves. If it is not, then investigate the cause and if necessary, report to the designer. When a flow measurement device
is not present on the branch, measure the differential pressure across the value and verify the minimum differential pressure listed in the submittal
to achieve desired flow rate.
7.
Repeat this procedures until all valves in the system have been set and their summated flows checked against upstream flow measurement devices
or differential pressure verification.
8.
Measure the differential pressure across the valve on the system index terminal (usually the most remote terminal from the pump). Adjust the
pump speed until the pressure differential across this valve is equal to the minimum valve indicated in the submittal.
9.
Determine the pressure differential at the sensor location. Set the pump speed to control such that the value indicated at the sensor is maintained
constant under all conditions.
10. Measure and record the total flow rate, pressure differential, and energy consumption at the pump.
11. Run all two port valves to their closed positions. Measure and record the total flow rate, pressure differential, and energy consumption at the
pump. Calculated and report the overall energy saving that is achieved between full load and minimum load operation.

Installation Instructions:
1.
The valve should be installed on the return side of the coil with the union end on the upstream side and other end on the
(except on the bypass line).
downstream side
How to use Bell & Gossett Circuit Setter Balance Valves for Pre-Set Flow Balancing: All Circuit Setter Balance Valves within a common zone,
circuit or system, with a common pump, are brought into balance with each other by establishing a common BALANCE GOVERNING HEAD LOSS
as noted.
CAUTION: Hot insulated surfaces can cause burns to the skin. Do not touch hot surfaces. Failure to follow these instructions could result in moderate personal injury.
1.
Identify a zone within a given circuit or circuit within a given system with the highest head loss.
2.
Establish the value of the head loss in feet of water.
3.
Establish the corresponding required GPM.
4.
Select the appropriate size Circuit Setter Balance Valve (normally line size) for the required GPM.
5.
Using Side #1 of the V91483 Circuit Setter Balance Valve Calculator, set the degree of closure hairline in the red section of the Calculator of the 0o
setting for the appropriate size Circuit Setter and read the head loss opposite the require CPM. The setting for this Circuit Setter will remain 0o.
6.
7.
Add the head loss in Step “5” to the head loss in Step “2” to establish the Balancing Governing Head Loss for the zone or circuit.
Subtract the required head loss for each zone circuit from the Balance Governing Head Loss in Step “6” to establish the head loss difference for
each zone or circuit which is to be brought into balance with Step “6”.
8.
The head loss difference in Step “7” and the required GPM in Step “3” are lined up in the white section of Side #1 of the
Calculator and the
degree of closure for the specific Circuit Setter Balance Valve is shown under the degree of closure hairline in the red section of the Calculator for
the appropriate size Circuit Setter.
9.
Adjust the Circuit Setter by turning the red knob by hand on sizes 1/2” through 1”, or by placing a wrench on the wrench flats provided on sizes 1
1/4” through 2 1/2” to the set position determined by the preceding procedure.
WARNING: It is possible, depending on the age or condition of the stem seal, for some liquid to escape during Circuit Setter adjustment. Do not have
eyes or face on a level with the sides of the Circuit Setter. Failure to follow this warning could result in serious personal injury.
NOTES:

Head loss in Steps “6” and “2” are a fixed head requirement the zone, circuit or system pump, as required, must overcome.

Refer to the G95872 prewired tag packaged with the Circuit Setter Balance Valve and fill in the appropriate information. Attach the tag to the Circuit Setter for future reference.
How to use Bell & Gossett Circuit Setters to Proportional Balance a System:
1.
2.
Open fully all Circuit Setters on a single pump system.
If more than one branch circuit is used, start the balance procedure by reading all of the flows to the units in a branch. Each unit (coil) should have
its own Circuit Setter for flow balancing. Using Bell & Gossett RP-250B readout probes, sequentially attach a Bell & Gossett differential pressure
readout kit to the readout valves on each Circuit Setter Balance Valve.
WARNING: Hot water leakage can occur from readout valve during probe insertion and during hookup of readout kit. Follow the instruction manual supplied with the readout probes and readout kit for safe use. Failure to follow this instruction could result in
serious personal injury and/or property damage.
3.
Using Side-2 of the Bell & Gossett Circuit Setter Balance Valve Calculator, with the top hairline set on zero for the size Circuit Setter being read,
read the flow corresponding to the pressure drop read with the read out kit.
4.
Calculate the ratio of the actual flow to the design flow for each unit in the branch. This is the proportional flow rate. (Actual flow divide by design flow.)
Select the Circuit Setter with the lowest proportional flow rater. This Circuit Setter is left in the full open position. Every other Circuit Setter in the
branch is then reset to the same proportional flow rate.
5.
WARNING: To ensure proper installation this product must be installed in conformance with
applicable building codes. Use of proper torque wrench is required.

Manual Circuit Setter Cont.
6.
If there are additional branches, repeat the steps in 3, 4 and 5 above for each branch.
7.
After all branches have been proportionally balanced, measure the full open flows on the Circuit Setters installed on the risers. Calculate the
proportional ration of each riser Circuit Setter and select the one with the lowest proportional ratio. This Circuit Setter is left fully open and the
other riser Circuit Setters are adjusted to this same ratio as described in (5).
8.
Adjust pump flow so that circuits are receiving their design flow. This can be accomplished by adjusting a Circuit Setter Balance Valve installed on
the pump discharge or by changing the pump impeller size.
IMPORTANT: Of a high degree of throttling of flow at pump discharge is required Bell & Gossett recommends that the pump impeller be sized to
produce design flow. This will reduce electrical energy consumption.
How to use Bell & Gossett Circuit Setter Balance Valves as Flow Meters:
1.
2.
Energize the zone, circuit and/or system pump(s) as applicable.
Using Bell & Gossett Model PR-250B Readout Probes, sequentially attach a Bell &Gossett differential pressure readout kit to the read out valves on
each Circuit Setter Balance Valves.
WARNING: Hot water leakage can occur from readout valve during probe insertion and during hookup of readout kit. Follow the instruction manual a
supplied with readout probes and readout kit for safe use. Failure to follow this instruction could result in serious personal injury and/or property
damage.
3.
Read the differential pressure across the orifice of the Circuit Setter Balance Valve.
4.
Using Side #2 of the Circuit Setter Balance Valve Calculator, set the hairline over the degree of closure as indicated by the part of the red plastic
knob or indicator plate parallel to the degree of closure noted on the calibration plate, and read actual GPM flowing through the Circuit Setter opposite the gauge reading head loss noted in the white section of Side #2.
NOTE: If the system contains a liquid with a specific gravity and/or viscosity higher or lower than that of water, apply the appropriate correction factor
noted in these instructions to obtain the actual GPM for the system liquid.
How to Bell & Gossett Circuit Setter Balance Valves as an Isolation Valve:
1.
Move the adjustment knob or stem until the position indicator aligns with the closed position on the calibration plate.
2.
Close the isolation valve on the other side of the equipment to be serviced.
3.
Open the drain valve to drain the system between the Circuit Setter and the second isolation valve.
WARNING: Check for proper sealing when using as an isolation valve. If the sea is not sealing properly, liquid will continue to flow from the drain
valves. In this case, Circuit Setter must be isolated from the system and replaced. Failure to follow these instructions could result in serious personal
injury or death and proper damage.
How to use the Memory Stop feature:
1.
Make the final degree of closure setting.
2.
Loosen the memory stop locking screw in the slot on the top of the red knob.
3.
Slide the memory stop screw in the slot (counter-clockwise for 1/2” - 1” sizes and clockwise for 1 1/4” - 2 1/2” sizes) until the screw stops.
4.
Tighten the memory stop screw.

Ball Valve
Installation Instructions:
1.
Ensure the pipeline is free of dirt of debris. Flush system if necessary. Foreign matter can damage valve or degrade performance.
2.
Thoroughly clean pipe threads and apply thread dope to the male thread only. PTFE thread sealant is recommended for most applications. (Installer is responsible for selecting a sealant compatible with fluid).
CAUTION: The use of “Teflon” impregnated pipe compound and “Teflon” tape on pipe threads provides lubricity. Care should be
taken to prevent over-tightening which may damage the valve body. Failure to follow these instructions can result in moderate personal injury and/or property damage.
CAUTION: Do not use pipe dope where thread sealant is pre-applied when connecting valves to ChamFlex/All Metal SS Braided
Hose Assemblies.
3.
Apply torque to the valve at wrenching flats nearest the end being assembled. Do not apply torque through the full length of the
valve body as this may compromise the integrity of the body to end piece seal. Care should taken not to over tighten as this as this
can cause distortion of the valve body and effect valve performance. Pipe wrenches should not be used on the valve as they can
crush the body distorting the NPT thread.
4.
A tight leak free joint can be obtained on valves 2” and under by rotating the valve 2 to 3 turns relative to the pipe, larger valves
should be turned 1 1/2 to 2 turns. (Basic Dimensions, American National Standards Taper Pipe Threads, NPT ANSI B1.20.1-1983.)
5.
After installation operate the valve through several full open to close cycles. Check tightness of stem packing.
6.
For valves with NPT side taps assembly is the same as end connections. Tighten the mating part 2 to 3 turns past hand tight while
holding the valve securely. The valve should be secured at the wrenching flats only. Applying a radical load on the main part of the
body can distort it.
Operation Instructions:
The valve is opened by turning counterclockwise one quarter turn and close by turning clockwise. Valve state is indicated by the lever. A
closed valve’s lever is at 90o to the valve axis. When the valve is open the lever lies along axis.
CAUTION: Hot insulated surfaces can cause burns to the skin. Do not touch hot surfaces. Failure to follow these instructions could
result in moderate personal injury.
WARNING: To ensure proper installation this product must be installed in conformance with
applicable building codes. Use of proper torque wrench is required.

Y-Strainer Combination Valve
Description: Y-strainer valves are of brass construction with an integrated ball valve, strainer, blow-down valve and union with tailpiece.
Installation Instructions:
1.
The valves must be installed on the supply side of the coil with filed end on the upstream side and other end on the downstream side.
2.
When installing the Y-strainer valves space around the units must be provided to move the valve handle to the shutoff position and to move the
strainer from the strainer body for cleaning.
3.
The Y-strainer must be installed with the strainer chamber down to prevent air binding and also to allow accumulated dirt to be blown down from
the strainer.
Operation Instructions:
Y-strainer can be used to isolate hydronic equipment for repairs and/or drain the system. To close the Y-strainer ball valve move the handle a quarter of
a turn until the handle is perpendicular to the valve and piping.
If Y-strainer pressure drop becomes excessive, accumulated dirt should be blown down through the blow-down line (if installed) to a drain. If a blowdown line is not installed see the service instructions for removing and cleaning the strainer. The Y-strainer have construction with an integrated ball
valve will function as a service valve.
Service Instructions:
If excessive pressure drop is measured across the Y-strainer the internal strainer has collected dirt/debris and needs to be cleaned. Install blow-down
line (hose), then open blow-down valve. If blowing down the strainer has not solved the pressure drop problem, the Y-strainer must be disassembled
and strainer cleaned.
WARNING: Failure to use proper hose connection to the blow-down valve may result in serious personal injury and property damage.
To clean the strainer, isolated the Y-strainer by shutting off the ball valve on upstream and downstream of the Y-strainer. Allow the system to cool
down to 100oF (38oC) or less.
WARNING: Hot fluid and/or fluids under pressure are a safety hazard. Do not service the strainer while it is hot or under pressure. Failure to follow
these instructions could result in serious personal injury or death and property damage.
Using the appropriate size wrench remove the brass cap on the Y portion of the strainer. Grab and remove the strainer. Clean the strainer in water to
remove collected debris. Reinstall the strainer and the strainer cap. Pressurize the system and check for strainer cap leaks. If noted, slightly tighten nut
until leakage stops.
Periodically inspect the Y-strainer for signs of corrosion or leakage. If corrosion or leakage is noted the Y-strainer must be replaced.
WARNING: Corrosion or leakage is indication that the Y-strainer Combination Valve must be replaced. Failure to follow these instructions could
result in serious personal injury or death and property damage.
WARNING: To ensure proper installation this product must be installed in conformance with
applicable building codes. Use of proper torque wrench is required.
