Assembly Instructions for Membrane Roof Style Snowguards # 15 & # 115

I. Base Plate (The base plate is the flat piece with the two threaded studs.)

1. A Continuous block is required underneath the membranous roof surface to attach the base plate. This base flange is 10 1/2" long. Mounting this system over insulation alone may crush the insulation and cause the roof to leak.
2. Place the base plate on top of the finished membrane roof. NOTE: The threaded studs on the base plate are not centered. Align the base plate so that the stud closest to the end faces the eaves of the building.
3. Before fastening base plate through membrane to mounting block below, apply a generous amount of acceptable sealer under the flange.
4. Fasten base plate to mounting block using 6 #10 screws.

II. Membranous Flashing of Base Plate

1. Use an acceptable piece of flashing material 18" square.
2. Cut two small holes in membrane flashing to fit tightly over threaded studs.
3. Before installing flashing apply a generous amount of acceptable sealer around threaded rods.
4. Apply flashing over base plate using proper mastics and installation techniques so as to create a water tight patch.
5. The threaded studs are now the only part of the base plate exposed. NOTE: Due to the sealer applied around the studs there may be bleed out at this opening. When the base block is installed and tightened this bleed out will help to create a water tight compression fitting.

III. Installation of snowguard block

1. Install base block over threaded rods. Just like the threaded studs of the base flange, the holes in the base block Slat accept the studs are not centered. Align the base block so that the hole closest to the edge faces the eave.
2. Place one gasket washer over each stud.
3. Place locking nut over gasketed washer and tighten.
4. Insert tubing through the holes in the uprights.
5. Apply a silicone or similar sealant to the couplings ( #85 ) and turn the couplings into each end of the tubing to be joined. NOTE: tubing is not threaded and does not need to be.

Il. End Collars, End Plugs, and Ice Flags (optional )

1. End collars ( #65 ) should be place over each end of each line of tubing. Center the tubing on the snowguards and tighten the set screw on the collar until it no longer slips.
2. End plugs are installed using the same method as the couplings. Set end of plug flush with end of pipe
3. Ice flags ( #95 )should be placed over the top tube so that the long leg rests against the uphill side of both tubes. Use the carriage bolt and nut to hold the ice flag in position.

Snowguard Specifications r Pipe Style Brackets * Above is the recommended layout pattern * Horizontal spacing between brackets is 48" maximum. This may be decreased do to variable conditions. * Snowguard layout should be repeated every 15' up the roof slope. * Tubing is 1" OD aluminum. * Brackets are made of aluminum and are available in other metals. * Three pipe systems are available upon request.

Alpine SnowGuards, Inc. will recommend bracket spacing and layout patterns based upon the information you provide. However, weather conditions and roof construction vary from project to project. The owner or architect must carefully consider factors such as anticipated snowload, roof slope, and orientation, roof construction and the area to be protected, in deciding whether the use of Alpine SnowGuards products would be appropriate. Alpine SnowGuards' assistance in your project design is limited exclusively to providing the specifications of its products. The owner or architect is solely responsible for evaluating the structure to determine its capacity to bear the retained snow loads.
