SD3000 Construction Choosing A Location For The Kiln SECTION 2 SD3000 CONSTRUCTION Choosing A Location For The Kiln Some considerations should be made when choosing a location for your SolarDry Kiln: Build the kiln so the collector faces within 5 degrees of due south if building in Northern latitudes.
SD3000 Construction Sill Plate Construction After the concrete slab has had sufficient time to cure, you may begin construction of the kiln chamber. Sill Plate Construction Refer to Drawing #2. Chalk a line 4" from each edge of the slab. Check the marked lines for squareness. NOTE: If the lines show the slab is not square, make adjustments at this time.
SD3000 Construction End Wall #2 Construction Install the three studs that make up the lead-in for the interior wall. Be sure the middle lead-in board is aligned with the inside face of the wall. Install nailers between the vertical studs for mounting plywood sheathing. Box in the area near the short end of the wall as shown for the air intake hole.
SD3000 Construction Front Wall Construction Front Wall Construction Refer to Drawing #6. Refer to the material table and cut lumber as shown. Build the front wall as shown. Install the end studs using 16D nails. Cut the top plate from 2x6 lumber and install. Square the frame and mark the stud loca- tions on the sill plate and top plate.
SD3000 Construction Back Wall Installation 2.10 Back Wall Installation Refer to Drawing #9. Cut spacers from 1/2" plywood and secure to the end wall studs. Install 6 pieces of drip edge to the back side of the door header. Position the drip edge so it points out to the rear of the wall (See detail).
SD3000 Construction Interior Sheathing/Insulation Installation 2.12 Interior Sheathing/Insulation Installation Refer to Drawing #11. Remove all wall bracing from the interior of the kiln chamber. Install 4" x 16" kraft-faced fiberglass insulation in the walls between each stud. Place the insulation so the paper face is toward the interior of the kiln to create a vapor barrier. Install the interior plywood using 7D nails.
SD3000 Construction Fan Shelf Construction 2.15 Fan Shelf Construction Refer to Drawing #14. Refer to the material table and cut lumber as shown. Build the fan shelf as shown. Install outside plates to interior kiln walls using 16D nails. The bottoms of the plates should align with the bottom angle of the support wall (see detail).
SD3000 Construction Lower Rafter Installation Install insulation between the studs of each door so the paper will face the interior of the kiln (see detail). Install the interior 1/4" plywood with 7D nails. Apply caulk between all plywood joints. Mark the doors to identify which is the interior side and set the doors aside to be installed later.
SD3000 Construction Loading Door Installation 2.21 Loading Door Installation Refer to Drawing #20. Install 36" hinges to back wall as shown. The top set of hinges should be 2" from the top of the door opening. The bottom set of hinges should be 10" from the bottom of the door opening.
SD3000 Construction Screen Installation 2.23 Screen Installation Refer to Drawing #22. Install the door screen to the bottom of the rafters. Cover the entire area between the mid- dle support wall and front wall (18’ - 6" x 11’ - 6"). Use staples to secure the screen to the rafters.
SD3000 Construction Electrical Installation 2.25 Electrical Installation DANGER! Hazardous voltage will cause severe shock, burns, or death. Disconnect and lock out all power to the equipment before connecting wires. Make sure all electrical installation is performed by a qualified electrician in accor- dance with applicable electrical codes.
SD3000 Construction Inner Plastic Installation 2.27 Inner Plastic Installation NOTE: Close all doors to the kiln before installing plastic. Refer to Drawing #26. Install one of the 20’ x 24’ plastic sheets over the kiln as shown. Position the plastic so it hangs evenly over each side of the kiln.
SD3000 Construction Intake/Exhaust Hardware Installation Finally, stretch the plastic down over the notched 2x2 spacers at the bottom of the kiln and secure to the front wall with furring strips 1" down from the notched 2x2 spacers. The inner and outer layers of plastic should form a channel where moisture can drain out. 2.29 Intake/Exhaust Hardware Installation Refer to Drawing #28.
Pre-Drying Procedures SECTION 3 OPERATION ® Your Wood-Mizer SolarDry™ Kiln is the simplest, most energy efficient dry kiln avail- able. It will give you many years of service with very little maintenance. The following steps are necessary to maintain the expected levels of less than 1% drying defects.
Page 20
Operation Pre-Drying Procedures Other common air-drying defects such as checking, honeycomb, splits, and warp can be controlled by using proper air-drying procedures. (See recommended reading list in Sec- tion 6.) Sort and sticker the lumber. Sort the lumber to be dried according to thickness and species. While it is best to load the kiln with the same thickness and species, it is not always possible.
Operation Drying Procedures Drying Procedures Load the kiln. Open the loading doors. Load the lumber into the kiln. Leave a minimum air space of 12 inches between the load and the back wall of kiln chamber. Block the air spaces between wood stacks with plywood, crushed newspaper, or plastic so that all air flow is directed through the stickered lumber.

Operation Drying Procedures After the kiln warms up, turn the circulating fans on at the main switch. Intake damper. Adjust the intake damper so the wood dries slow enough to avoid degrade. Thicker stock will require a lower maximum drying rate than thinner stock. Different species also will require different maximum drying rates.
Operation Solar Kiln Maintenance Solar Kiln Maintenance 1. Replace the collector cover at the first sign of age cracking, approximately every 2-4 years. It is advisable to keep a spare cover around at all times in case of emergency. 2. Small tears or holes in the collector plastic can be repaired with silicone caulk and a small piece of kiln plastic.
