Overview and Application

The document provides technical specifications, installation guidelines, and product features for the DEVOREX roof drainage system, designed for rainwater management on residential, administrative, and light industrial buildings. The system complies with EN 12056-3 standards and must be designed by authorized professionals considering local building codes.

Design and Calculation Parameters

• Rainfall intensity used for calculations: 80 liters per hour per square meter (80 l/(m²·h)).
• Effective roof rainfall area calculation formula: S = (W + H/2) × L, where W, H, and L are roof dimensions.
• Running outlet must be positioned at least 10 meters from the slope start.
• Flow rates vary with slope and position of outlet, e.g., at 8 mm/m slope in the middle of the roof, flow rate is 4.4 l/sec for 200 m² area.

Product Features and Advantages

• Available in multiple saturated colors (White RAL 9010, Grey RAL 7038, Brown RAL 8019, Beige RAL 1015, Terracotta RAL 8023, Bordeaux RAL 3009) with no need for painting.
• Invisible gutter brackets provide a modern, hidden fixing system.
• State-of-the-art UV protection ensures durability of PVC components.
• Corrosion resistance extends product lifetime and reduces maintenance costs.
• Reliable installation system allows secure fixation and thermal compensation for watertightness.
• 2-in-1 design combines two gutter styles for flexibility and aesthetics.

Installation Guidelines

1. Storage: Gutters and pipes must be stored above ground on wooden pallets or beams with supports every 50 cm, avoiding twisting or bending. Outdoor storage requires a minimum 5° slope for drainage.
2. Do not cover system elements with foils that prevent air circulation.
3. Operating temperature range: -35°C to +65°C.
4. Handling: Avoid sliding pipes and gutters over each other to prevent surface damage.
5. Bracket fixing: Attach gutter fascia brackets to fascia board using 5x30 mm screws or M6x50 bolts; maximum spacing between brackets is 50 cm; maintain 5-10 cm distance between brackets and other gutter elements.
6. Gutter installation: Slide gutter edges under retaining clips, hang front edge on bracket clips without fixing to allow movement during installation; glue connecting elements with PVC-U glue at edges.
7. Thermal expansion: Adjust gutter unions according to outside temperature during installation.
8. Pipe brackets: Install at max 150 cm apart or 75 cm from pipe ends; secure brackets after placing pipes.
9. Special fixings: Use bracket adaptors for tile or bitumen roofing; for roof ribs, use side or top rafter brackets with M6x50 bolts for slope adjustment.
10. Warning: In heavy snowfall areas, avoid bracket adaptors or rafter brackets; fix gutters directly to fascia board.

Safety and Additional Recommendations

• In regions prone to snow and ice, install ice/snow protection fixtures to prevent falling hazards.
• Ensure all pipes and fittings are glued with PVC-U glue for watertight connections.
• Use appropriate screws (M6) compatible with mounting surfaces for downspout end fittings.

Components and Accessories

The system includes a variety of components such as gutters (3 m lengths), gutter unions, stopends (right and left), angles (90° interior and exterior), running outlets (Ø100), rainpipes (Ø100), pipe connectors, brackets (fascia, rafter, adaptor for tile and bitumen roofing), bends (67.5° and 87.5°), ending bends, reducers (Ø100/Ø80), and fastening hardware (M6x50 bolts and nuts).
