IMPORTANT: All Avonni Window and Door units must be installed per the installation instructions. If units are not installed in a manner that conforms to the manufacturer’s installation instructions, the warranties will be null and void.

Please read entire installation instructions carefully and thoroughly before starting.

These instructions apply to both 2-panel and 4-panel doors.

Inspect for Damage:

Carefully inspect the unit for shipping or handling damage. Shipping damage may include scratched or broken glass, damaged sash, broken jambs or cladding. If the unit does not meet the specifications ordered or has any shipping damage, do not install the unit and contact your local A&H Windows distributor. All shipping locks and packaging must be removed from the unit prior to installation.

Installation of Unit:

  1. Check rough opening to ensure that opening is level, plumb and square

Verify that width and height dimensions are correct. Rough opening should be 1/2″ wider than overall frame width and 3/4″ greater than overall frame height. Sill plate should be flat and level. Make sure opening is dry, clean and free of dirt and debris.

NOTE: Flashing and/or an appropriate method of sealing shall be designed as a part of an overall weather-restrictive barrier system. It is not the responsibility of the window manufacturer to design or recommend a flashing system appropriate for each job condition. For flashing instructions, follow all local building codes applicable to the construction applications. Avonni strongly recommends the use of a sill pan.

  1. Next, apply two continuous beads of polyurethane sealant across the width of the sill, approximately 1/2″ – 1″ in from the interior and exterior edges of the rough opening. The sealant should extend 6 inches up each side of the frame members. One additional bead should be applied along the inside down-turned leg of the sill pan.

This will create a seal between the sill pan and the sill. Set the sill pan in place and make sure that it is fully seated in the sealant, especially the front lip.

  1. Once in place, apply a bead of sealant just above the back corner of the sill pan. The bead should be continuous and extend across the entire length of the sill pan. A continuous bead should then be applied near the exterior edge of the sill pan. Complete the sealant application by applying a bead along the top lip of the sill pan end to seal between the pan and the rough framing.
  2. Apply a continuous nominal bead of sealant along the backside of the nailing flange along the backside of the nailing flange along both side jambs and head. Run additional sealant across the 45º joint where the flanges meet.

Make sure the butyl pad is in good condition and properly adhering.

  1. Insert and center the door in the rough opening. When doing so, tilt the door back so that the sill can be set into the opening and onto the sealant; and do not scrape it off the sill pan.
  2. With the door set into the rough opening, check to make sure it is centered. Tack the door in place with one 1-1/2″ screw (or equivalent) in the top nailing flange within 3″-6″ of each corner.

Make sure that the sill is straight, flat and level. Use a tape measure to measure the diagonal dimensions of the frame to ensure the frame is square. This measure should be double-checked by using a framing square.

Shim at the top of the side jambs as required. Use a level or straight edge to ensure the jambs are straight. Also check frame width across head, center and sill. IMPORTANT: Proper shimming is required to ensure the unit will perform properly.

  1. Place a shim behind each keeper slot of the strike plate on the lock side jamb (2-panel door only). Place #8 x 3″ screw (provided) into each hole at both ends of each keeper slot. #8 x 7/8″ screws are inserted into the remaining screw holes in the strike plate. It is recommended that the holes be pre-drilled into the framing. Make sure that the door is fully seated in the opening before inserting screws.
  2. Use a 1/8″ drill bit to pre-drill into the header through the holes in both halves of the head track. Insert 3″ steel screws. Do not over-tighten. Check to make sure frame head is level. The active panel(s) will have to be opened completely to expose the empty holes in the head track. When unlocking without the use of the handle set, use a standard screwdriver to activate the lock. The door will not lock unless the active panel(s) is (are) closed completely.
  3. Adjust door panel and striker bar to ensure proper operation and locking. Complete the fastening of the door to the structure using stainless steel screws (or equivalent) and securing the nailing flange to the sheathing. Fasteners should be spaced every 12″ to 14″.
  4. If required, attach a support block made from pressure-treated or decay-resistant wood (not provided) underneath the exterior lip of the sill.
  5. With the unit completely secured to the structure, apply a bead of sealant at the edge of the head jamb nailing flange where it meets the sheathing. Also, apply similar beads of sealant between the edge of the side jamb nailing flange and the flashing material. Toll the sealant into the joint to ensure the joint is filled.
  6. Apply a layer of flashing over the side jamb-nailing flange.

The length of the flashing should equal the height of the rough openings + (2x width of the flashing material) -1″. Install the flashing so that the edge contacts the inside corner of the nailing flange. The top of the flashing should extend only 8-1/2″ above the top edge of the door-frame; Make sure that the side flashing overlaps and covers the ends of the sill flashing. Repeat for opposite side.

  1. The length of the head flashing should equal width of rough openings + (2x width of the flashing material) + 2″. Extend 1″ beyond edge of each side flashing. Attach top edge of flashing to the wall.
  2. Complete installation by applying sealant around the perimeter of the unit after the exterior wall finish has been applied.

Removing the Operating Panel:

  1. Remove the interior head stop (located at the head jamb). Gently pull downward, starting from one end and release from kerf fastener.
  2. Remove the bumper stop block from the stationary side of the head jamb.
  3. The head track is installed in two pieces (four pieces on the 4-panel door). Begin by removing the stationary side head track by removing screws. With the operating panel completely closed, remove this piece of head track. Take care to note from which side each head track piece was removed. It is important to replace each track piece to the same location from where it was removed.
  4. Slide the operating panel into the open position so that it is against the stationary side jamb.

CAUTION: Take care to support the top of the operating panel so it does not fall. Remove the screws from the operating side head track. Then, while moving the operating panel towards the closed position, slide the head track back through the plow at the top of the operating panel.

F or 4-panel door:

Operator side head track can be pulled straight down after removing screws. Do not have to slide over top of the panel.

  1. Slide the operating panel into the closed position and remove the remaining head track piece from the head jamb.

CAUTION: Take care to support the top of the operating panel so it does not fall.

  1. With both tracks removed, tilt the top of the panel towards the interior and carefully lift it off the roller track.

CAUTION: Lift with care. Panels are very heavy. Use two people to remove panel. 7. Set the panel down carefully so as not to damage the panel extension at the exterior side of the panel bottom.

Installing the Operational Panel:

  1. Remove the interior head stop (located at the head jamb); gently pull downward starting from one end and release from kerf fastener.
  2. Remove the bumper stop block from the stationary side of the head jamb.

For 4-panel door: Repeat opposite side.

  1. Remove the stationary and operating sides of the head tracks from the head jamb by removing the screws. Take note from where each track piece was removed so they can be replaced in the same correct position later.
  2. Set the bottom of the operating panel onto the sill making sure that the rollers are properly aligned and setting on the roller track.

CAUTION: Lift with care. Panels are very heavy. Use two people to install panel.

  1. Once the rollers are on track, tilt the panel into place and hold it in position. Carefully slide the panel a few inches to ensure the rollers are tracking properly.

CAUTION: Take care to support the top of the operating panel so it does not fall. The panel should roll easily.

If it does not, reposition until rollers are on the track.

  1. Slide the operating panel into the closed position. Slide the operating side head track through the plow at the top of the panel while slowly moving the panel into the open position. Pull the head track piece over the panel and position against the side jamb.

Again, make sure that the correct track piece is inserted and screw into place.

Be careful not to pinch the bulb weather-strip between the head track and slide jamb.

For 4-panel door: Slide the panel into the closed position and engage the operating panel interlock with

the stationary panel interlocks. While holding the active panel in place, insert the stationary side head track into the plow and secure into place with screws.

  1. With the operating panel in the closed position, place the stationary side head track into the head jamb. Secure the stationary side head track with screws. F or 4-panel door:

Slide the operating panel into the open position and place the operating side head track into the head jamb. Screw the track into place. Repeat steps 6 and 7 to install the second operating panel.

  1. Re-apply the head stop onto the exposed kerf fastener. Re-apply the bumper stop block.

Panel height adjustment: The height of the operating panel can be adjusted by accessing the height adjustment screw on each roller. To access the screw, remove the cap from both holes at the bottom of the panel on the interior side.

Insert a large slotted or Philips screwdriver into the screw and turn counter-clockwise to adjust the panel upward. Adjust the rollers as needed to ensure a proper fit between the panel and frame.

For 4-panel doors:

Adjust the rollers on the second active panel as on the first. The panels should be set to the same height and must be parallel with one another.

Strike bar adjustment: The strike bar can be adjusted via the slotted holes in the base plate. By slightly loosening the screws, the bar can be adjusted up or down to achieve correct alignment with the lock mechanism. Do not over-tighten.
