Gutter systems

CORRECT POSITIONING
OF THE RUNNING OUTLET

When choosing a gutter system to install, first make sure that gutters and down pipes can receive all the water from the roof surface of your building. You can verify the roof drainage capacity by calculating the so-called Effective Roof Surface which the gutter system should drain.Calculate the Effective Roof Surface with the formula below: ERS = (A+B/2) x C A – horizontal distance from the corner to the roof ridge (m) B – roof heigh [m] C – roof length [m]

INSTALLATION BASICS

A correct installation of a PVC gutter sy stemguarantees its durabilityand reliable operation for years, even in harsh weather conditions. In
comparison to traditional roof drainage solutions, the main advantageof our gutter system can compensate for thermal variation in the length of individual components. This is achieved thanks to a correct design of gutter and pipe fittings. This compensation is enabled by the sliding joints between the guttersand the fittings equipped with flexible gaskets, whereas the down pipes feature an installation clearance at the socket joints of pipe fittings. The roof and wall fasteners of the gutter system, such as the gutter hangers and clamping rings act as structural supports that stabilize the system and enable compensation for thermal length variation.

PREPARING THE EPDM GASKETS FOR INSTALLATION

Wet the EPDM gaskets of all gutter system components (on the drop outlets, the universal corners, the gutter joints and the end caps). This will facilitate sealed snap-on connections. Verify that all EPDM gaskets are held snugly in their grooves when joining the components together.

CORRECT POSITIONING OF GUTTERS UNDER THE EAVES

A correct installation must protect the gutters from impact by the snow sliding down the roof. The upper edge of gutter flanging should not go over the roofing edge, as shown in the figure above

POSITIONING THE DROP OUTLETS

The first step of the gutter system installation process is to locate the drop outlet which is the lowest component in the gutter line.

INSTALLING THE GUTTER HANGERS

Fasten the gutter hangers directly to the fascia board of the roof. The maximum spacing of the gutter hangers is 40 cm. Install the gutter line with a downgrade of 2 mm in height per 1 m of length towards the drop outlet.

SETTING THE CORRECT GUTTER DOWNGRADE

First, fasten the gutter hanger furthest from the drop outlet position along the roof edge, then fasten the drop outlet. Use a tightly tensioned string to set the correct gutter line downgrade between the two fastened components. Proceed with fastening the components directly to the fascia board along the string’s line.

TRIMMING THE GUTTERS AND DOWN PIPES TO SIZE

Trim the gutters to size by cutting square to the gutter centreline with a fine tooth saw

CONNECTING THE GUTTER TO THE DROP OUTLET

Slide the gutter end under the inner flanging of the drop outlet. Snap the gutter end snugly within the inner flanging at its connection marks

INSTALLING THE GUTTER JOINTS

Insert the gutter under the inner flanging of the gutter joint until the gutter snaps into the front flanging. Next, slide the gutter under the holding paws, down to the connection marks.

INSTALLING THE END CAP

The end cap is designed to be mounted on either end of a gutter. Mount the end cap snugly on the entire end edge of the gutter.

INSTALLING THE DOWN PIPES UNDER THE EAVES

Push fit the down pipes with the fastened drop outlets, elbows and down pipe joints. If the eaves go more than 10 cm in front of the wall, make a down pipe offset by trimming a straight down pipe section to size. Install the elbow, the trimmed down pipe section, another elbow and the down pipe running down the wall. Leave a 10 mm clearance to compensate for the thermal length variation of the pipe.

INSTALLING THE DOWN PIPE CLAMPING RINGS

Fasten the down pipe clamping rings to the wall with the hook bolts and plugs in the wall holes. Use the stabilising façade flanges if the hook bolts feel loose in the wall. The maximum spacing of the down pipe clamping rings is 2-2.5 m.

INSTALLING THE DOWN PIPE JOINTS

Push fit the down pipe joints between the down pipes. The arrow marks on the components must match the running direction of drained water. Leave a 10 mm clearance in each down pipe connection socket to compensate for thermal length variation
