Minimizing Condensation

Note: Please reference EFCO's "Understanding Condensation" brochure which can be obtained through your EFCO
representative.
Condensation will form on any surface when unfavorable conditions (interior temperature and relative humidity and
exterior temperature) are present. When the formation of excessive condensation is a concern, it is highly recommend ed that a
design professional is utilized to perform an analysis of the shop drawings to recommend the best possible installation methods.
Please contact your EFCO representative for information on EFCO's Thermal Analysis Services.
Many current installation practices lead to an increase in the possibility of the formation of condensation. Though not all
inclusive, the list of examples below illustrates conditions under which condensation is lik ely to occur:

1. Bridging system thermal break with non-thermally broken metal flashin g or lintels that are exposed to the
exterior

2. System exposure to cold air cavities

3. Interior relative humidity levels not maintained at recommended levels, see EFCO’s “Understanding
Condensation” brochure

4. Inadequate separation between system and surrounding condition at perimeter

5. Product combinations during the shop drawing stage that result in bridging thermal breaks
of one or all products involved

Note: Assembly Instructions are provided as a supplement, and should be used in conjunction with the approved shop drawings.

Section 1: General Notes And Guidelines

HANDLING / STORING / PROTECTING ALUMINUM

The following guidelines are recommended to ensure early acceptance of your
products and workmanship.

A. HANDLE CAREFULLY - Store with adequate separation between

components so the material will not rub together. Store the material off the
ground. Protect materials against weather elements and other
construction trades.

B. KEEP MATERIAL AWAY FROM WATER, MUD, AND SPRAY - Prevent

cement, plaster, and other materials from contacting with and damaging
the finish. Do not allow moisture to be trapped between the finished
surface and the wrapping material.

C. PROTECT MATERIALS AFTER ERECTION - Wrap or erect screens of

plastic sheeting over material. Cement, plaster, terrazzo, and other
alkaline materials are very harmful to the finish and are to be immediately
removed with soap and water. Under no circumstances should these
materials be allowed to dry or permanent staining may occur.

GENERAL GUIDELINES

The following practices are recommended for all installations:

A. REVIEW CONTRACT DOCUMENTS – Become thoroughly familiar with

the project. Check shop drawings, installation instructions, architectural
drawings and shipping lists. The shop drawings take precedence and
include specific details for the project. Shop drawings govern when
conflicting information exists in the assembly and installation instructions.
Note any field verified notes on the shop drawings prior to installing.
EFCO assembly and installation instructions are general in nature and
cover many conditions.

B. INSTALL ALL FRAMING MATERIAL PLUMB, LEVEL, AND TRUE –

Proper alignment and relationships to benchmarks and column
centerlines, as established by the architectural drawings and the general
contractor, must be maintained.

C. ERECTION SEQUENCE - The sequence of erection should be

coordinated with the project general contractor to prevent delays and
minimize the risk of material damage. Note: When preset anchors are
required, coordinate and supervise anchor and insert placement with the
general contractor including insert layout drawings, where required.

Manufacturing, assembly, glazing, and shipment of the preglazed units
must be carefully coordinated with the general contractor to ensure a
continuous and sustained flow of materials to the appropriate areas of the
project to meet the project schedule.

D. PERIMETER CONDITIONS - Verify that all job site conditions and

accompanying substrates receiving the installation are in accordance with
the contract documents. If deviations occur, notification must be given in
writing to the general contractor and differences resolved before
proceeding further with the installation in the area in question.

E. ISOLATION OF ALUMINUM - Prevent all aluminum from coming in direct

contact with masonry or dissimilar materials by means of an appropriate
primer. Typical slab anchors may be set directly onto concrete surfaces in
a block-out pocket at the edge of the slab. The block-out pocket is later
filled in with grout thereby covering the slab anchor. In such cases, a
heavy coat of zinc chromate or bituminous paint must be pre-applied to
the slab anchor.

F. SHIPMENT VERIFICATION - Verify contents of all material shipments

received upon their arrival. Verify quantity and correct finishes. Notify

EFCO immediately of any discrepancies or damage that may have
occurred.

G. SEALANT - All sealant must meet [ASTM C 920, CLASS 50]. For the

purposes of these instructions, sealant is to be defined as the following:
SEALANT - A weather resistant, gunnable liquid filler which when cured
provides a resilient, flexible (± 50% movement capability min.) air and
water seal between similar and dissimilar materials.

All sealant must be compatible with all surfaces on which adhesion is
required, including other sealant surfaces. All frame surfaces should be
clean, dry, dust, and frost free. If a primer is required, it must be applied to
clean surfaces. All perimeter substrates shall be clean and properly
treated to receive sealant. All sealants and primers must be applied
according to the sealant manufacturers instructions and
recommendations.

This system is designed and has been tested to utilize silicone sealants at
all internal joineries, i.e., joint plugs, gasket intersections, etc.

EFCO 2009 Page 3

Series 8700 / 8800 Unitized Curtain Wall Installation Instructions

Section 1: General Notes And Guidelines

It is the responsibility of the glazing contractor to submit a statement from
the sealant manufacturer indicating that glass and glazing materials have
been tested for compatibility and adhesion with glazing sealants, and
interpreting test results relative to material performance, including
recommendations for primers and substrate preparation required to obtain
adhesion. The chemical compatibility of all glazing materials and framing
sealants with each other and with like materials used in glass fabrication
must be established.

Maintain caulk joints as shown in the approved shop drawings. A 1”
minimum joint is required at the head and jamb condition to accommodate
installation, building movements, and thermal expansion and contraction.

H. STRUCTURAL SEALANT JOINTS - The maximum allowable size of the

glass lite is controlled by the width and depth of the structural silicone joint
combined with the specified design wind load (PSF or Pa). The stress on
the structural silicone must not exceed 20 PSI (137 KPa) for a 6:1 safety
factor.
In order to determine the structural silicone sealant contact width or bite
which adheres the glass to the frame, a calculation must be performed on a
job by job basis. The formula which determines the sealant width is based
on using a trapezoidal load distribution rule. This formula is expressed as
follows:

Structural Sealant = 0.5 x Short Span (ft) x Wind load (lb/ft²)
Bite or Contact Width (in) Sealant Design Strength (=20 lb/in²) x 12 in/ft

Example: Lite size is 4’0” x 5’0” and wind load for the project is 60 psf.

Structural Sealant = 0.5 x 4’ x 60 psf

or 120 or .500”

Bite or Contact Width (in) 20 x 12 240

Sealant manufacturers, as a general rule, specify the structural sealant
depth (glue line) to be one half of the contact width for a 2:1 width to height
ratio. The glue line should not exceed 3/8” thickness nor be less than 1/4”
thick. The standard joint size for Series 8000 is 1/2” x 1/4”. Note: Weather
seals must be applied a minimum of four hours after the application of the
SSG sealant joint to allow for proper cure time.

I. SECONDARY SEALANT JOINT DESIGN - The design of the secondary

sealant joint is based on the 50:50 load sharing principal where the I.G. unit
is comprised of two symmetrical lites of glass. The secondary sealant joint
that adheres the two lites of glass together only carries half the wind load
applied to the I.G. unit. Since the load is halved, the secondary sealant
contact width is half that of the SSG joint. Using the example earlier for the
1/2” x 1/4” SSG joint, the secondary sealant contact width for the I.G. unit in
the example is 1/4”.

Edge deletion is required on the coated surface (#2 or #3) for hard or soft
coated glazing products.

Section 3 - Static Starter Sill Preparation and Installation

Projects will be produced by EFCO in one of three ways: 1) As a stock length product whe re all fabrication, assembly, and glazing will be performed by
the customer, or: 2) Prefabricated “knock down” where EFCO fabricates the materials, and the customer performs the assembly, and glazing, or:

3) EFCO will provide a completely fabricated, assembled and glazed product. The materials shown here in the installation instructions may be received
in the field with varying degrees of shop assembly, with some items shop installed, and other items to be field installed. Certain assembly and install ation
procedures shown and described in this document may be performed in the shop or the field at the discretion of the assembler.

1. Preparation of the Static Starter Sill:
a. The static starter sill may have an end dam pre-attached and sealed at the jamb condition. Ensure that the end dam is properly applied and sealed

to the starter sill as described below. This is a critical seal and the joint must be carefully tooled to create a watertight seal. See Figures 1, 2, and 3.

b. The starter sill may have gaskets (WC19 and LC23) pre-applied. The LC23 is cut to the length of the starter sill while the WC19 will be

approximately 6” to 8” longer than the starter sill. Do not cut off excess WC19. The excess gasket will be slid into the adjacent starter sill during
installation.

c. Plug the end of the tubular section of the starter sill at the jambs and corner conditions by recessing backer rod at least 1/4” into the end of the tube.

Fill the voids in the tube and between the thermal struts with sealant and tool smooth. Intermediate splice locations incorporate an int ernal splice
sleeve and will be covered later in this section.

Clean all sealant contact surfaces using an approved solvent or cleaner of all oils and other contaminants. The sealant manufacturer’s
preparation and application instructions should be followed exactly. If sealant primer is required, apply it per the primer/sealant
manufacturer’s instructions.

d. A gutter base anchor (FM01 or FM02) is required at each intermediate vertical and jamb. Two are required at corner mullion conditions. The

anchors are used to transfer wind load reactions from the verticals into the anchoring system. Before installation of the static starter sill, slide the
appropriate number of gutter base anchors into each section of starter sill. See Figures 4 and 5.

e. Slide the gutter base anchors into final position after the starter sill anchor bolts have been applied.

2. Verify that all job site conditions and accompanying substrates receiving the installation are in tolerance and are in accordance with the contract documents.

3. Pre-cleaning the substrates where the caulk joints will be applied later may be advisable prior to setting the starter sill. Final cleaning and sealant primer

application where required should be performed only immediately before caulk joint sealant applicatio n.

4. Use established bench marks to ensure the accuracy of the starter sill location. Precise measurements and coordination with regard to established bench

marks are critical to ensure that the starter sills are installed in the correct location. Improperly installed, or miss-located starter sill s will cause significant
problems for the remainder of the erection process.

5. Starting at the jamb, place the starter sill into the opening hard on the condition in the final position, excluding elevation. Match drill the substrates at the

anchor locations and apply the anchors allowing for shim space under the starter sill. Refer to the approved shop drawi ngs for type, size, and specific anch or
details. Shim the starter sill to the proper elevation height making sure the starter sill is level. The shims used must be full bearing shims. The shims must
fully support the entire load bearing surface of the starter sill at each anchor location. Refer to the project structural calculation package and final approved
shop drawings for detailed information.

6. EFCO recommends minimum of a 1/2” caulk joint between the starter sill and the condition.

7.

When applying anchor bolts to the starter sill, pre-fabricated serrated washers (17D3) must be used. The serrate d wa shers will lock the starter sill into
position when the anchor bolt is tightened. See Figures 7, 8 and 9. After verifying the final position of the starter sill, secure the anchor bolts as required.

8.

Put a temporary shim between the end dam and the condition to protect the end dam during unit installation. The required shim thickness will vary due to
field tolerances and project specific joint size requirements, but a minimum of 1/2” is reco mmended. Remove the shim after unit installation.

5. Starting at the jamb, place the starter sill base into the opening hard on the condition in the final position, excluding elevation. Match drill the substrates at

the anchor locations and apply the anchors allowing for shim space under the starter sill base. Refer to the approved shop drawings for type, size, and
specific anchor details. Shim the starter sill base to the proper elevation height. Ensure that the starter sill base is true, level, and plumb.

6.

When applying anchor bolts to the starter sill base, pre-fabricated serrated washers (17D3) must be used. The serrated washers will lock the starter sill base
into position when the anchor bolt is tightened. See Figures 25, 26 and 27. After verifying the final position of the starter sill, secure the anchor bolts as
required.

7.

Put a temporary shim between the end dam and the condition to protect the end dam during unit installation. The required shim thickness will vary due to
field tolerances and project specific joint size requirements, but a minimum of 1/2” is reco mmended. Remove the shim after unit installation.

Section 7 - Unit Inspection and Preparation for Installation

1. Before installing the units, follow this checklist to ensure they are ready for installation:

a. Inspect the units to ensure that each unit has all external gaskets and screws. The WC19, WC20 and WC21 gaskets will be shop crimped in place.

Verify these gaskets have been crimped securely to the frame. WC16 is a push-in type gasket. Always check for proper crimping and for missing
gaskets.

b. Using an approved solvent or cleaner, clean the vertical and horizontal stack gaskets of all oils and other contaminants (WC19, LC23,

WC21 and WC20).

c. The 17D9 sta ck joint caulk backer is shop applied to the frame. Ensure the 17D9 in intact and properly applied. See Figure 58. The 17D9 will be

shop attached with sealant. Make sure the caulk backer aligns with the notch in the vertical.

d. Mullion plugs are required at the head and sill of the captured system in the ends of the verticals. The mullion plugs will be shop applied and sealed

in place. Check to ensure the mullion plugs have been properly applied.

e. Using an approved solvent or cleaner, clean the sealant contact surfaces of the expansion cavity of the stack sill and 17D9 of all oils and

other contaminants. See Figure 62.

f. Apply a generous amount of sealant in both ends of the cavity approximately 4” long. See Figure 62.
g. Place the HC07 foam backer into one end of the cavity with approximately 4” extending out of the cavity. The HC07 foam backer should be applied

to the jamb where the backer will be exposed after the frame has been set. See Figure 64. The HC07 will be applied at both jambs on the jamb
condition unit on each row. All sequential units will get sealant on both jambs but will only get one HC07. These units will get the HC07 in the jamb
opposing the previous unit.

h. Run a small bead of sealant (1/16” diameter) approximately 3” up from the bottom, in the female jamb interlock cavity only. See Figure 64. Apply

this sealant immediately before setting the unit. Do not apply too much sealant as this will interfere with stacking the frames together.

Section 8 - Setting Units at Static Starter Sills

1. Static starter sills are used with installations that don’t require provisions for vertical movements at the beginning floor of the curtain wall.

2. Units are typically installed from left to right from as seen from the exterior of the building. Install each frame unit in sequence, starting at the left jamb unit.

3. Units are lifted by the splice bars attached at the head of each unit. These bars are also used to align the units when stacked vertically.

4. Ensure the HC07 caulk backer has been inserted into the sill as shown in Figures 62 and 64 on page 31. Note that jamb units will receive HC07 on both
ends of the sill. Subsequent units will require HC07 on the right end only of the unit sill as viewed from the exterior.

5. Lower the jamb unit down into position onto the starter sill. The hook anchors should also be hooked onto the slab anchors. The unit should now be setting
hard on the starter sill. See Figures 66 and 67.

6. Installations utilizing the static starter sill must use a wind load anchor at the first floor above the starter sill as shown in Figures 68 and 69. All consecutive
floor slabs above the wind load anchor will be the typical dead load anchor as shown in “Section 10 - Setting Typical Intermediate Units”.

7. Place a shim pack between the jamb mullion and the condition to prevent the jamb unit from shifting when setting successive units.

1. If the starter sill was properly installed and the unit is square and is setting hard on the starter sill, the unit will be at the proper elevation and will be level and
plumb from side to side.

2. Compare the jamb unit to established bench marks and move the unit side to side to position it laterally to the final required location.

3. Adjust the unit for plumb, parallel to the plane of the wall, by sliding the slab anchor forward or backward until the unit is plumb. See Figure 70.

4. Rotate the serrated washers where the serrations align with the serrations in the anchor and secure the slab anchor’s anchor bolts.

5. Match drill the slab anchors through the hook anchors on both sides of the unit, and install the pinning screw to lock the frame unit into the final position. See
Figure 71.

Section 8 - Setting Units at Static Starter Sills

8. Once the unit is approximately 1/2” above the engagement leg of the starter sill, use clamps to snap the mullions together. Place one clamp at the center of
the mullion at the bottom of the units. Use wood blocks to protect the finished surfaces of the mullions. Tighten the clamp until the mullion halves begin to
snap together. Place another set of wood blocks and a clamp a couple of feet up the unit mullions and tighten it until the mullions snap together. Repeat this
process up the length of the mullion until the mullion halves are snapped together continuously. It may be necessary to work from one clamp to the next
several times, or move the clamps to ensure the mullions are snapped together evenly. See Figure 75.

9. Lower the unit the rest of the way down until it sets hard on the static starter sill.

10. Slide the unit laterally to adjust the mullion width to 3”.

Section 9 - Setting Units at Dynamic Starter Sills

1. Dynamic starter sills are used with installations that require provisions for vertical movements at the beginning floor of the curtain wall.

2. Units are typically installed from left to right as seen from the exterior of the building. Install each frame unit in sequence, starting at the left jamb unit.

3. Units are lifted by the splice bars attached at the head of each unit. These bars are also used to align the units when stacked vertically.

4. Ensure the HC07 caulk backer has been inserted into the sill as shown in Figures 62 and 64 on page 31. Note that jamb units will receive HC07 on both
ends of the sill. Subsequent units will require HC07 on the right end only of the unit sill as viewed from the exterior.

5. Place a temporary 9/16” shim between the unit sill and the back of the gutter at the dynamic starter sill. The shims are used to maintain the correct spacing
at the stack joint area of the starter sill. See Figures 78 and 79.

6. Lower the jamb unit down into position while inserting the anchor bar (FM03 or FM04) and stacking the unit onto the starter sill. The hook anchors should
also be hooked onto the slab anchors. The unit should now be setting hard on the shims. See Figures 79 and 80.

7. Place a shim pack between the jamb mullion and the condition to prevent the jamb unit from shifting when setting adjacent units. See Figures 78 and 79.

8. Compare the jamb unit to established bench marks and move the unit side to side to position it laterally to the required location.

9. Adjust the unit for plumb, parallel to the plane of the wall, by sliding the slab anchor forward or backward until the unit is plumb. See Figure 82.

10. Rotate the serrated washers where the serrations align with the serrations in the anchor and secure the slab anchor’s anchor bolts.

11. Tighten the jack bolts of the mullion anchors just tight enough so that the shims can be removed and the unit stays in the nominal position. See Figure 79 on
page 37. Remove the shims between the sill and the starter sill that were applied in step 5.

12. Set the unit to the required elevation height and level it by turning the jack bolt at each mullion anchor clockwise to raise, or counterclockwise to lower the unit
in to the final position.

13. Match drill the slab anchors through the hook anchors on both sides of the unit, and install the pinning screws to lock the frame unit into the final position.
See Figure 83.

Section 12 - Applying Critical Seals

1. Once the two units are installed, a splice is required at the gutter at the top of the units. Clean the gutter sill sealant contact surfaces using an approved
solvent or cleaner of all oils and other contaminants where the gutter splice will be applied. The sealant manufacturer’s preparation and
application instructions should be followed exactly. If sealant primer is required, apply it per the primer/sealant manufacturer’s instructions.

2. Apply a bed of sealant on the gutter that will cover the area where the gutter splice (HC08 or HC09) will be applied. When creating the bed of sealant, apply
a generous amount of sealant directly on top of the primary seal location as shown in Figure 121.

3. The sealant must go from the front of the gutter up the engagement leg to the WC19 gasket track. See Figure 123 of the following page. The sealant bed
must be wide enough to cover the entire area of the gutter splice (HC08 or HC09). See Figure 122.

4. Lay the gutter splice into the bed of sealant. Press the gutter splice up under the WC19 gasket track. See Figure 123. Smooth the splice down onto the
gutter, forcing out all air bubbles.

5. Apply sealant around the perimeter of the gutter splice. Tool the sealant to ensure a watertight seal at the splice. See Figure 124.

6. Apply sealant in the gap between the two starter sills from the WC19 gasket, across the top of the engagement leg and down the back leg. Tool the sealant
into all voids to ensure a watertight seal. See Figure 124.

1. The typical jamb and starter sill are as shown below in Figures 125 and 126. The line of sealant at the jamb will follow the front edge of the back member.

2. The condition at the head is job specific. Refer to approved shop drawings for sealant details.

3. The caulk joint at the starter sill is located at the exterior part of the starter sill and must return at the jambs to marry with the perimeter caulking of the jambs.
See Figure 129 on the following page.

4. Insert a backer rod into the reveal on the end of the starter sill. Recess the backer rod into the cavity of the reveal at a minimum of 1/4”. Seal off the end of
cavity with sealant and marry it into the end dam sealant. See Figure 127.

5. Special care is needed to ensure that the end dam is properly sealed and marries into the perimeter sealant correctly at the jamb to sill condition. Place a
piece of backer rod between the end dam and the jamb. The backer rod will run from the front face of the end dam to the engagement leg. Run a bead
sealant between the end dam and the jamb. Tool the sealant to create a water tight seal between the end dam and the frame. See Figures 128 & 129.

6. Place backer rod and run perimeter sealant at the sill and jamb. See Figure 129. Ensure that the sealants all marry together to create a water tight seal.

7. At jamb conditions of the unit stack joint, an end dam is pre-installed. Special care is needed to ensure the end dam is properly sealed and marries into the
perimeter sealant correctly. See Figures 131 - 132.

8. Place a piece of backer rod between the end dam and the jamb. The backer rod will run from the front face of the end dam to the engagement leg. Run a
bead sealant between the end dam and the jamb. Tool the sealant to create a water tight seal between the end dam and the frame. See Figure 13 0.

9. Insert a piece of backer rod between the end dam and the condition and seal over the top of backer rod and down the front of the end dam. See Figure 131.
Marry the two sealant lines together across the top of the end dam.

10. Insert backer rod around the rest of the perimeter and run perimeter sealant at the jamb. Ensure that the sealants all marry together to create a water tight
seal. See Figure 132.

Section 14 - Deglaze / Re-glaze Procedures - Captured System

1. The captured system units are structural silicone glazed to the frame. The deglaze and re-glaze procedure must be performed from a swing stage or man lift
from the exterior of the building. Follow the sealant manufacture’s sealant application instruction for deglazing and re-gla zing. Wh en deglazing an opening
or openings at a captured unit, follow these instructions:

a. Remove the wedge gaskets from the perimeter of the day-lite opening of the lite to be deglazed.
b. Remove the glazing beads, setting blocks, and side blocks from around the opening.
c. Using tool s, such as automotive deglazing tools, cut though the glazing sealant removing glazing, old gasket and sealant from the opening. Some

areas may be accessible from the interior.

d. Cut away the sealant from the substrate, leaving a thin film (approximately 1/32” thick) of sealant on the frame. Do not damage the surface finish of

the substrate. Alternatively, if the remaining sealant exhibits adhesive failure, completely remove all sealant, but take care not to damage the
substrate finish.

e. Remove all remaining gasket pieces or sealant residue from inside the gasket reglets.

Note:

It may be necessary to remove
gasket and or bead from lites
above or below the deglazing area.

Section 14 - Deglaze / Re-glaze Procedures - Captured System

2. When re-glazing an opening or openings at a captured unit, follow these instructions:
a. Using an approved solvent or cleaner, clean the glazing surfaces of all oils and other contaminants. The sealant manufacturer’s

preparation and application instructions should be followed exactly. Fresh sealant will adhere to cured sealant without primer. Primer may be

necessary if the sealant has been completely removed.
b. Replace WC18 preset spacer gasket with new gasket around the entire opening. Ensure the gaskets are firmly butted together in the corners.
c. Run a bead of sealant around the WC18 gasket as shown below. The joint must be filled with sealant in excess so that it will fill all voids between the

glazing and the WC18 gasket when the glazing is put in place. Tool the sealant into a beveled shape as shown b elow prior to setting the glazing.

Ensure no voids or air bubbles are present in the sealant. The glazing must be set within 10 minutes or before the sealant begins to skin over.

Note:
Only silicone sealants which have been
developed and tested specifically for
structural glazing applications should
be used for re-glazing purposes.

3. When re-glazing an opening or openings at a captured unit follow these instructions:
a. Carefully insert new setting blocks in the locations as noted in the approved shop drawings.
b. Clean the new glass or panel and set it in place, centered in the opening, setting on the setting blocks. Do not contaminate the sealant contact

surfaces of the glazing during handling. Press the glazing firmly against the spacer gaskets. Avoid sliding the glazing around on the spacers, as this

can force sealant into visible areas seen from the interior. See Figures 137 and 139.
c. Apply temporary retainers with wedge gaskets (WC22) at quarter points of the D.L.O. on all four sides of the opening. See Figures 137 and 139.
d. Tool the sealant around the perimeter of the glazing, packing the sealant into the joint, to ensure any voids or air bubbles in the sealant are

eliminated. Carefully relocate the glazing retainers to expose inaccessible areas behind the retainer, and tool the sealant at those areas. Pay

particular attention at the corners of the glazing. See Figure 138 and 140.
e. Inspect the weep system in the cover and glazing pocket and confirm the weeps slots and holes are intact and unobstructed.
f. Remove and replace the temporary retainers with a glazing bead and gasket (WC22) jon one side of the glazing at a time. Replace one side, and

then replace the opposing side next. Replace the remaining sides last. If the exterior gaskets were damaged whe n they were removed, replace

them with new gaskets. See Figure 138 and 140.
