CAUTION
Corrosive fluid is contained inside this unit.
These instructions should be thoroughly read
before operation is attempted.
The operator (s) of this instrument should thoroughly familiarize themselves with the
applicable safety precautions before handling or using the FYRITE for gas analysis.
Review Figures 1a,1b, 1c and 1d on this page. Make certain to follow the steps
outlined below and read the fluid handling precautions for your personal safety.
1) Always use protective equipment such as safety goggles, gloves, and protective
clothing as illustrated in Figure 1a.
2) Read the instruction manual thoroughly. When filling the FYRITE with the
applicable fluid charge, use safety equipment and perform the operation in the
vicinity of running tap water (Figure 1b).
3) The FYRITE fluid should always be in the bottom reservoir before and during
sample introduction to the FYRITE. When venting the FYRITE to atmosphere,
hold the instrument in the vertical position and at a location away from your face
(Figure 1c).
4) NEVER vent FYRITE in the inverted position (with the plunger facing downward). This will cause fluid to spill, which is corrosive and contains harmful
elements (Figure 1d).
NOTE: In the event of fluid spill - refer to Section 2.2 (FYRITE Handling
Precautions). For Maintenance - refer to Section 6.0.

The FYRITE employs the well-known “Orsat” method of volumetric analysis involving chemical absorption of a sample gas, such as carbon dioxide or oxygen. The
reagent used to absorb carbon dioxide (CO2) is potassium hydroxide (dyed red), and
chromous chloride (blue) is the absorbent for oxygen (O2). The unique feature of the
FYRITE is that the absorbing fluid is also used as the indicating fluid so that one
vessel takes the place of both measuring burette and absorption pipette.
The body of the FYRITE is molded of clear high-strength plastic, comprises top and
bottom reservoirs and a center tube connecting the two reservoirs. The bottom of the
lower reservoir is sealed off by a synthetic rubber diaphragm that rests on a perforated metal plate. The upper reservoir is covered by a molded plastic cap that
contains a double-seated plunger valve. A spring holds this valve against a carefully
finished seat in the top cap providing a perfect seal which makes the instrument
spill-proof in any position. When the valve is partially depressed, the entire instrument is open to the atmosphere and the instrument is, of course, is no longer spillproof.
The bottom reservoir is filled with the absorbing fluid, which extends about 1/4 inch
into the bore of the center tube when the instrument is held upright. The scale
position, mounted to one side of the center tube, is adjustable.
2.0 FYRITE INSPECTION BEFORE AND DURING TEST
CAUTION
Corrosive fluid is contained inside unit, instructions should be
thoroughly read before operation is attempted.
2.1 Pre-Operational Check
To ensure proper FYRITE operation and reliable results, check the following:
(a) With FYRITE vented and in a vertical position, it should be possible to adjust
scale zero to the top of the fluid column. Refer to FYRITE Operation for proper
setup (Section 3.0 Steps 1 through 5). If this is not possible, add or remove a
small amount of fluid per Section 6.1.

10. This step completes CO2 or O2 FYRITE gas sample analysis. A few points to
remember when reading the FYRITE:
(a) FYRITE accuracy is within ±1/2% CO
or O2 compared to actual value.
2
(b) Always handle FYRITE by fins to ensure body heat is not absorbed by fluid.
(c) A delay in reading of 5 or 10 seconds may decrease accuracy of reading
slightly but longer delays may cause substantial error.
(d) The FYRITE is calibrated to indicate on a “dry” basis for flue gas samples,
which are normally fully saturated with moisture. Failure to artificially
moisten wool packing in Filter Saturator Tube when actual sample is not
fully saturated will cause FYRITE to read slightly low.
Therefore, make certain wool packing in Filter Saturator Tube is sufficiently moistened with water for accurate results on non-flue gases. Avoid
excessive moisture which can be drawn into the Aspirator Bulb and forced
into the FYRITE during sampling.
CAUTION
Never depress plunger valve to vent FYRITE in the inverted
position. This will cause fluid to spill, which is corrosive and
contains poisonous elements. In the event of a spill, read Instructions in Section 2.2 FYRITE fluid handling precautions.
3.1 Determining CO2 and O2 FYRITE Fluid Strength
FYRITE Fluid strength can be conveniently checked immediately after the first
sample reading. Without venting, repeat the absorbing operations (Steps 7 through
9) by inverting FYRITE again and positioning upright until all fluid drains to the
bottom reservoir. Observe scale reading. An increase of more than 1/2% CO

3.2 Operating Precautions to Ensure Maximum Accuracy
Locate top of fluid column (refer to Fig. 11). The surface at the top of the fluid
column (meniscus) in the small, center bore will be dish-shaped as shown in Figure 11. Either the high or low point of this dish-shaped surface may be used to
locate top of fluid column providing the same point is always used both for setting
scale zero and reading percent CO
operation and low point for the other will cause an error.
Best practice is to use high point of this fluid surface just at the small center bore
wall. In setting scale zero or reading percent CO

2
Page 12
3.2.1 Draining Fluid Droplets
For maximum accuracy, it is important to form the habit of following a standard
procedure in this operation and to use the same procedure both before adjusting
scale zero and before reading percent CO2 or O2 .
3.3 FYRITE Temperature
The FYRITE temperature should be at or close to the temperature of the working
environment where the analysis is being made and should not be subject to sudden
temperature changes. If FYRITE is carried from cooler to warmer location or vice
versa, expose FYRITE to new temperature condition to permit uniform temperature
stabilization. Usually 15 or 20 minutes will suffice, except when extreme temperature variations are involved. Temperature stabilization can also be accelerated by
inverting FYRITE frequently.
3.3.1 Temperature of Gas Sample
The gas sample as it enters FYRITE should be cooled (or warmed if sampling cool
gases) to same (ambient) temperature as the FYRITE.
Capacity of Standard Aspirator Bulb and Sampling Assembly (Part # 11-7029) to
cool the gas sample is sufficient if the temperature of gas being sampled does not
exceed 850°F (454°C), even where a large number of consecutive samples are
required if there is an interval of not less than 5 minutes between samples.
FYRITE indicators operate over a wide temperature range. They may be exposed to
ambient temperatures from –30° to 150°F (–34° to 66° C). Gases up to 850° F
(454° C) may be tested with Standard Aspirator Sampling Assembly (11-7029).
Special sampling equipment for high temperatures and unsaturated gas samples are
listed in Section 7.2. FYRITE Sampling Assemblies.

Figure 12. When plunger
valve is depressed, a gas
sample is pumped through
top reservoir with center
bore is sealed off.
Figure 14. Absorption of
gas sample by fluid creates
suction, which causes
diaphragm to flex up and
fluid to rise in center bore
to replace gas absorbed.
Figure 13. When plunger
valve is released, the gas
sample is locked into
FYRITE and the top
reservoir is opened to
center bore so that gas
sample can pass through
absorbing fluid.
Instruction 11-9026Page 9
Page 14
To make a test with the FYRITE, the metal Sampling Tube at one end of Sampling
Assembly Hose is inserted into the gas to be analyzed. The rubber Connector Plug at
the other end of the Rubber Hose is then firmly pressed down on the spring-loaded
Valve of the instrument (See Figure 12). This simultaneously opens a passage into
the Top Reservoir and seals off the center bore.
Next, a sample of the gas is pumped into the Top Reservoir by squeezing the rubber
Aspirator Bulb. At least 18 bulb squeezes are required to assure that the rubber
Sampling Hose and the Top Reservoir of the FYRITE are thoroughly purged of the
previously analyzed sample. During the 18th Aspirator Bulb squeeze and immediately before releasing Bulb, the finger is lifted from the Connector Plug, which
automatically returns the Plunger Valve to upper position against its top seat.
Refer to Figure 13. With the Valve in this position, the final 60 cc of the gas sample
is locked into the FYRITE and the Top Reservoir is opened to the center bore so that
the gas sample can pass to the absorbing fluid. The FYRITE is then inverted, forcing
the gas sample to bubble through the absorbing solution which absorbs either CO
or O2 depending on the type FYRITE in use.
2
Refer to Figure 14. The instrument is then turned and held upright. Absorption of
the CO
at the bottom to flex upward permitting the level of the absorbing fluid to rise in the
or O2 by the absorbing fluid creates a suction, which causes the Diaphragm
2
center tube an amount proportional to the gas absorbed. The scale indication
corresponding to the top of the fluid column is then read as a percentage of gas
absorbed by the FYRITE fluid.
5.0 APPLICATION INFORMATION
FYRITE Analyzers are available for either Carbon Dioxide or Oxygen analysis, and
each of these models is made in the three scale ranges shown in Section 5.3. All six
instruments are similar in appearance and size, but they differ in important construction details, as well as in absorbing fluids.
5.1 FYRITE Absorbing Fluid
FYRITE absorbing fluid is selective in the chemical absorption of carbon dioxide or
oxygen respectively. Therefore, the FYRITE’s accuracy is well within the range
required for industrial and professional applications, and does not depend upon
complicated sequential test procedures. Furthermore, the FYRITE readings are
unaffected by the presence of most background gases in the sample.
The appearance of a dark red fluid floating on top of CO
entirely normal. The darker fluid consists of a small amount of material added to
prevent excessive foaming at the meniscus and improves readability.
5.1.1 FYRITE Refill Fluid (Storage Life, etc.)
FYRITE refill bottles should be stored at room temperature (70° F [21° C]) in the
carton provided, and placed in use within one year.
NOTE: Before opening refill bottle, read the label and make
certain to observe all precautions.

Page 15
FYRITE CO2 refill fluid may develop a white insoluble precipitate upon aging. The
precipitate does not affect fluid performance in any way, but if present, should be
filtered out to prevent adherence to internal surfaces of the FYRITE.
To filter, place a clean piece of thin cloth or netting loosely over the open CO
FYRITE and slowly pour refill contents into top reservoir. Before disposing of cloth,

5.2 FYRITE Operating Temperature Range
The FYRITE indicators operate over a wide temperature range, and may be exposed
to ambient temperatures from –30° to 150° F. (–34° to 66°C). Gases up to 850° F
(454° C) may be tested with standard aspirator sampling equipment (11-7029).
Special sampling equipment to reduce high combustion gas temperatures (2000° F
[1093° C]) to usable FYRITE temperature (ambient) and assemblies with extra large
saturators for dry gas sampling are listed in Section 7.2, FYRITE Sampling Assemblies.
NOTE: Remember, for most accurate results, the FYRITE
must be at temperature equilibrium with its surroundings
(ambient temperature) and the incoming gas sample at the
same temperature as the FYRITE.

5.4 CO2 FYRITE Only Combustion Testing
5.4.1 Percent CO2 Shows Volume of Excess Air (Refer to Figure 15)
For any given fuel, theoretical maximum percent CO
produced when exactly enough air (but no excess air whatsoever) is supplied to burn
all of the fuel. As increasing amounts of excess air are supplied, percentage CO
naturally decreases from theoretical Ultimate CO2 due to the diluting effect of
excess air.
Thus, measuring percent CO

Excess combustion air is heated and carries some of this heat to the flue where it is
wasted. The FYRITE CO

Consult manufacturer of heating equipment for specific recommendations. Generally
accepted values for good combustion practice in residential furnaces and boilers

2
2
These are only guidelines, however, and in all cases recommendations of the equipment or fuel supplier would also include recommendations for allowable smoke (oil
firing) or combustibles (gas firing), which are undesirable combustion by-products.
Testing for smoke, CO, or combustibles is important since in extreme fuel rich
firing, high CO
values also occur (see Figure 16).

2
Deduct temperature of basement or combustion air supplied from measured flue gas
temperature to obtain net flue gas temperature. Use a Bacharach FIRE EFFICIENCY FINDER to calculate combustion efficiency. Instructions for using the
FIRE EFFICIENCY FINDER are printed on the face of this slide rule calculator.
5.5 O2 FYRITE Only Combustion Testing
5.5.1 Percent O2 Shows Volume of Excess Combustion Air (Refer to Fig. 15)
All fuels require some excess air (in addition to air theoretically required to burn the
fuel) to ensure clean, complete combustion. As the amount of this excess air increases, the percentage of O2 in combustion products increase.
5.5.2 Too Much Excess Air Means Inefficient Combustion
Excess combustion air is heated and carries some of this heat to the flue where it is
wasted. The FYRITE O2 analyzer is used when adjusting combustion air to minimum excess air (minimum O
Instruction 11-9026Page 13
) which will permit clean, efficient combustion.
2
Page 18
5.5.3 What is Proper O2 Value?
Proper O
clean combustion with adequate safety margin for variations in fuel, draft, atmo-
content for any fuel fired is the lowest O2 value that will ensure complete,
2
spheric conditions, and mechanical wear. Consult manufacturer of heating equipment or local authorities for specific recommendations. Figure 15 illustrates the
relationship between CO
, excess air and oxygen for gas and oil.
2
For guidance, it should be added that modern boilers are capable of 80% or greater
combustion efficiency. Rough guidelines for setting conventional power burners are
10-15% excess air for natural gas and 15-20% excess air for oil, with little or no
smoke and carbon monoxide formation.
5.5.4 Measuring O
in Addition to CO

A check must also be made for the presence of oxygen, which confirms operation
with excess air. Gaseous fuels should also be checked for presence of carbon monoxide (CO) in the flue gases and adjusted for either “no CO” or to conform to applicable
safety regulations.
5.5.5 Where is Percent CO
For residential and most commercial and industrial combustion units, percent CO
or O2 is measured by analyzing gas sample obtained through a 1/4-inch diameter
or O2 Measured? (Refer to Figure 17)

hole located between the flue outlet (breeching) and any mechanical opening in the
flue such as the barometric draft regulator or draft diverter. Best practice is to
locate sampling hole at least six inches upstream from such flue openings. The
metal FYRITE Sampling Tube should extend at least 2-1/2 inches into the flue
gases.
For larger installations, consult manufacturer of combustion equipment for special
instructions regarding sampling point, special sampling tube required, or advice on
averaging readings.
Residential gas furnaces with built-in draft diverter (gas designed) will require the
FYRITE metal Sampling Tube to be inserted as illustrated in Figure 17 to avoid
dilution of flue gas sample.

5.6 Background Gases Affecting FYRITE Readings
As a rule of thumb, background gases/vapors may be present in concentrations up to
1/2% by volume (5000 ppm) before they present a significant interference problem to
the CO
An exception exists with the action of ammonia on Oxygen FYRITE Fluid. Ammonia
neutralizes the acidic solution of chromous chloride, and therefore use of the O
FYRITE with even trace amounts of ammonia in the backgrounds is not advised
unless suitable filters are used.
Inert gases, even in concentrations approaching 100% by volume, do not interfere
with either the CO
(chemical reaction initiated) or a mechanical nature, with resultant error, but are
also given up by the solution when the sample no longer contains the interfering
substance. They can therefore be compensated for by saturating the FYRITE
solution with samples containing the mechanical interferant as long as the background stays reasonably constant. Usually 3 or 4 tests are sufficient to saturate
FYRITE solution with the mechanical interferant in question.

5.7 General FYRITE Applications
It is only possible to specify a few general rules for such applications. Where possible, sample should be obtained at a point where the gases are well mixed to a
uniform composition. Where this is impossible; it will be necessary to average a
number of measurements taken at different locations to obtain representative
average. Where gases being sampled are not saturated with moisture (many noncombustion applications), it is very important to maintain the wool packing of Filter
Saturator Tube in a moist condition.
NOTE: The FYRITE is calibrated to analyze gases which are
normally saturated with moisture. Failure to moisten wool
packing in filter saturator tube with water will cause FYRITE
to indicate slightly lower than actual gas concentration.
Where special length sampling lines are required, add one more bulb squeeze to the
18 required with standard Sampling Assembly for each additional 3 cubic inches
(50cc) volume of special sampling line.
EXAMPLE: For each 9 ft. of 3/1 6 inch (I.D.) additional
length of sampling line, add one more bulb squeeze.
If it is necessary to trap a sample over water for later analysis, a minimum of 900 cc
of sample will be required. If sample is trapped over water, it is good practice to use
10 to 15% NaCl (table salt) in the water to minimize absorption of CO
water.

Trapping a sample over mercury will eliminate any possible error due to absorption
of CO
or O2.

5.8 Altitude Correction Table
The gas concentration read on the FYRITE is directly dependent upon the mass of
air in the sample. The aspirator bulb used in the FYRITE is a constant-volume
pump, not a constant-mass pump. Altitude, therefore, affects the FYRITE reading
due to the air’s density changing with altitude, thus requiring higher CO
concentrations to reach the same mark on the scale.
Use the following table to find the altitude correction (e.g., add the correction to the
reading to get the correct concentration).

6.0 FYRITE MAINTENANCE
NOTE: With FYRITE vented and in a vertical position, it
should be possible to adjust scale zero to the top of the fluid
column. Refer to FYRITE Operation (Section 3.0) Steps 1
through 4 (for CO2) or Steps 1 through 5 (for O2) for proper
setup. If this is not possible, add or remove a small amount of
fluid as described below.
6.1 Increasing FYRITE Fluid To Proper Level
Refer to Figure 18. Hold FYRITE upright and cover hole in center of Plunger Valve
with finger. Add clean water, a few drops at a time (dripping water faucet is convenient) into space around Plunger Valve. Work Plunger Valve up and down several
times. Repeat process until fluid is at proper level.
Page 18Instruction 11-9026
Page 23
6.1.1 Decreasing FYRITE Fluid to Proper Level
Refer to Figure 19. To remove excess fluid, insert small diameter glass tube into
FYRITE fluid through the small center FYRITE bore (with Top Cap Assembly
removed). Seal open end of glass tube with finger and dip out fluid with glass tube
until FYRITE fluid is at proper level. Avoid unnecessary exposure of O
since it will rapidly absorb O2 and become exhausted.

while exhaling breath. Release rubber connector tip from Plunger Valve while still
exhaling breath. Perform steps outlined below to absorb exhaled breath into
FYRITE fluid.
1. Absorb sample gas into FYRITE by inverting until fluid drains into top reservoir, then turn upright to drain fluid into bottom reservoir. Repeat this step
once more (two complete inversions total).
2Hold FYRITE at 45° angle momentarily to allow fluid droplets to drain into
bottom reservoir.

6.3 Replacing FYRITE Fluid (Refer to Figs 20, 21, and 22)
CAUTION
Because of the corrosive effect of the FYRITE fluid, always
change FYRITE fluid in immediate vicinity of a sink with
running water available as shown in Figure 18.
Instruction 11-9026Page 21
Page 26
Remove 4 screws, metal Top Cap Ring, plastic Top Cap Assembly and Top Gasket.
Drain old fluid from FYRITE and rinse all parts in clean, lukewarm water.
NOTE: FYRITE fluid is corrosive to skin, clothing, some
metals, and painted or lacquered surfaces. Dispose of these
fluids in accordance with Local, State and Federal Laws. If
draining into a porcelain sink is permitted, keep water faucet
turned on while draining and flush for at least 1/2 minute
afterwards.
NOTE: Examine top gasket for warpage, if distorted as shown
in Figure 22, replace gasket with part # 11-0143 before
proceeding.
Drain all parts of excess water. Stand FYRITE Body upright to center replacement
Top Gasket in recess provided in top flange of body.
O2 FYRITE Only: Before adding fluid, flush FYRITE with a stream of O2 - free,
inert gas (Figure 21) or be prompt in reassembling Top Cap to prevent excessive
fluid contact with air.
Uncap FYRITE fluid bottle, invert FYRITE and place over the bottle. Invert both
FYRITE and bottle (Figure 21a) so that FYRITE comes to an upright position and
the fluid is filling the unit. Immediately install plastic Top Cap Assembly and metal
Top Cap Ring without delay.

in place between metal Top Cap Ring and plastic Top Cap. Draw the 4 machine
screws down with light screwdriver force.
Then, going from one screw to the next, draw down 1/4 turn until all are firmly
tightened. Avoid excessive force in tightening which may damage plastic parts.
6.4 Inspection of FYRITE for Fluid Leakage
Gradual loss of fluid, moisture or dried encrustation around Plunger Valve does not
indicate fluid leakage. Gas enters and leaves unit during sampling with considerable velocity and some fluid vapor is carried out during normal sampling. To check
Top Assembly for fluid leakage in upright position, depress Plunger Valve and
release.
Note the scale reading at top of fluid column, and then stand FYRITE upside down
overnight in glass or porcelain test dish (See Figure 23). Then, return FYRITE to
upright position and, after allowing 5 minutes for drainage, depress and release
Plunger Valve. Leakage will be evidenced by lower scale reading. Extreme leakage
will be apparent by presence of fluid in test dish.

Follow the same procedure to check fluid leakage from Bottom Cap Assembly with
FYRITE stood overnight in the upright position.
When leakage is proven, examine plastic and rubber parts for deterioration to
determine replacement parts necessary for repair, or drain instrument and return if
factory service or repair is desired.
6.5 Cleaning FYRITE
Use only soapy lukewarm water if cleaning is required (lukewarm water is usually
sufficient).
NOTE: Use of gasoline, naptha, carbon tetrachloride or any other
organic solvent or oil will destroy plastic and rubber parts.
6.6Replacing FYRITE Plastic and Rubber Parts (Refer to Illustrated
Parts List FYRITE CO
Replace plastic parts when cracked or crazed in location exposed to fluid and rubber
parts when badly swollen, warped or showing other evidence of deterioration.
In replacing Top Gasket, make certain it is properly centered in the recess provided
in top flange of FYRITE Body (See Figure 24). When installing plastic Top Cap
Assembly, be sure that assembly is centered on Top Gasket.
To remove Top Cap Assembly or replace Top Cap, Plunger Valve, or Plunger Tip
Gasket, use the procedure as outlined in Section 6.3.
[Section 7.0 and Fig. 33])
2/O2
When replacing Plunger Tip Gasket, simply depress Plunger Valve against its
spring limit and strip old Tip Gasket from the end of Plunger Valve.
Before assembling new Gasket, wet inside surface of Tip Gasket, then force it over
the end of Plunger Valve (after depressing Plunger Valve against the spring limit).
Make certain that new Tip Gasket is seated uniformly against the mating surface in
plastic Top Cap.
To replace Diaphragm, stand FYRITE upside down, remove 4 screws and metal
Bottom Cap.
Refer to Figure 25a. Remove old Diaphragm and center new replacement with the
lettering facing you, so that after the FYRITE Bottom Cap is installed the letters will
face up into its recess. Center Bottom Cap Assembly in Body Recess and reinstall 4
screws, observing same precautions in tightening as outlined in Section 6.3.
To replace Body, remove the 4 hex head Bezel screws and 4 Bezels. Install Bezels on
new Body.
NOTE: Make certain the rubber bezel gaskets are properly
seated and clamped between bezel and body as shown in
Figure 25.
Defective Check Valves or a leaking Sampling Assembly can result in sample loss, or
sample dilution with resultant loss of accuracy.
To inspect Sampling Assembly, seal hole in the center of rubber Connector Tip
firmly with finger and squeeze Aspirator Bulb (Figure 27). Bulb should remain firm.
If Bulb collapses, check Bulb and Hose to Connector Tip for cracks or other source of
leakage. Replace defective parts. If there are no apparent leaks in the Sampling
Assembly, replace Inlet Check Valve. Small hole end of Inlet Check Valve fits inHose and large hole end fits in the Aspirator Bulb (Figure 26).
Now seal end of metal Sampling Tube with finger, and collapse Aspirator Bulb.
(Figure 28). If the Bulb returns to original shape in less than 15 seconds, inspect
Hose, Filter, Saturator Tube and Metal Sampling Tube for leaks. If none are found,
replace the Outlet Check Valve. Small hole end of Outlet Check Valve fits inAspirator Bulb and large hole end fits in the Hose (Figure 26).
Discard Filter Packing when it becomes dirty or clogged. Push old packing out of,
and new packing into, Filter Saturator Tube with a pencil or small rod (See Section 6.9).
6.8 Storing FYRITE and Refill Fluid
When FYRITE is not used over periods between tests, store it and its Sampling
Assembly in a cool, dry place. Prolonged storage, for example, at high temperatures
reached in an automobile trunk over the Summer is not recommended. When stored
unused over the Summer, it is good practice to drain old fluid and replace with fresh
charge (fluid) when needed in the Fall.
FYRITE Refill Fluid should also be stored in a cool, dry location in the carton
provided. A recommended practice is to accumulate stock only sufficient for one year
requirement and to use oldest stock first. Fluid can be tested for performance
according to Section 6.2.
Use only Bacharach CO

(Refer to Figs 29 thru 32)
Remove the filter tube nipple and bushing (See Figure 29) from each end of the tube.
Use a pencil or similar object to remove packing when it becomes dirty or clogged.
Wrap replacement packing around the hand (See Figure 30). If testing unsaturated
gases (most non-combustion applications), saturate packing in water as shown in
Figure 3, and squeeze out excess moisture.
Insert saturated packing using a pencil or small rod into filter tube (See Figure 32);
then reassemble nipple and bushing.
