GUTTER SYSTEM BRYZA PVC INSTALLATION

CORRECT INSTALLATION A GUARANTEE OF RELIABILITY

When choosing a gutter system, calculate the so-called Effective Roof Surface using the following formula: ERS = (A+B/2) x C A - horizontal distance from the corner to the roof ridge (m) B - roof height (m) C - roof length (m) 0°C Minimum installation temperature

GENERAL ASSEMBLY RULES

Correct installation of a PVC gutter system is a guarantee of its long-term durability and reliability, even in difficult weather conditions. In comparison with traditional solutions, the main advantage of the construction is the ability to compensate for thermal changes in the length of its individual elements. This is achieved thanks to the appropriate design of gutter and pipe joints. In gutters, it is implemented through a slidable connection with gutter joints equipped with flexible gaskets, and in downpipes, through assembly slack at the connections with pipe joints. Moreover, elements that fasten the gutter system to the roof and building walls, such as gutter hangers and down pipe clamping rings, not only stabilize the system but also allow compensation for variations in its length. If gutters are fitted to gutter strips made of galvanised metal sheet, they must be painted or coated. The gutters under the eaves should be installed below the line which is an extension of the roof surface, so that they are not subjected to sliding snow loads.

CORRECT LOCATION OF GUTTERS UNDER EAVES

Correct installation must protect gutters against the impact of snow slid­ing down a roof. The upper edge of gutter flanging should not protrude over the extension of the roof surface, which is represented in the pic­ture.

CUTTING GUTTERS AND DOWN PIPES

Cut the gutter into suitable length, at the right angle, with a fine-toothed saw.

INSTALLATION OF HANGERS

PVC hangers with straight or twisted fascia boards, as well as straight or twisted steel hangers are mounted directly to the laths or rafters. The distance between the hangers should be 40–50 cm. In order to drain water properly, gutters should have a decline in the direction of the drop outlet of min. 2 mm per 1 m.

6

INSTALLATION OF HOOKS AND CLAMPING RINGS

The first step in the system installation process is to locate an outlet drop, i.e. the lowest element of the system roof section.

7

DETERMINING OF GUTTER DECLINE

At first, mount the hanger located farthest from the drop outlet, and then the hanger next to the drop outlet. Extend two strings between the hangers and establish the correct decline of the gutter. PVC hang­ers are mounted directly to the face board.

8

INSTALLATION OF GUTTERS IN HANGERS

In PVC and metal hangers, the installation process should begin with putting the pipe flanging into the front nose of the hanger and then forcing in the internal part of the gutter under the rear nose.

9

INSTALLATION OF DROP OUTLET

A corner, drop outlet and gutter joint should be mounted together by inserting onto the front gutter flanging and latching on the rear gutter flanging. Gutter ends should be situated around 5 mm in front of the limiters.

10

INSTALLATION OF END CAP

Installation of the end cap should start from inserting it into the front gutter flanging and latching it on the rear gutter flanging. Pay attention to the correct position of the gaskets.

11

INSTALLATION OF CLAMPING RINGS

Clamping rings are fixed to a wall using clamp hooks of correct length. If neces­sary, an additional supporting façade flange is used. Clamping rings on down pipes should be spaced at least every 2–2.5 m.

12

INSTALLATION OF GUTTER JOINT

A corner, drop outlet and gutter joint should be mounted together by inserting onto the front gutter flanging and latching on the rear gutter flanging. Gutter ends should be situated around 5 mm in front of the limiters. While connecting, pay attention to a correct position of gas­kets located in drop outlets, joints and corners, as well as to the limit­ers located on internal surfaces of these elements. We also recommend mounting additional gutter hangers on the gutter-gutter joint and gut­ter-drop outlet connections.

13

INSTALLATION OF DOWN PIPES

Connect down pipes with drop outlets, elbows and gutter joints using the push-fit system. In case the eaves protrude over 10 cm beyond the wall, the set-off should be extended by a section of a down pipe. Mount the elements in the following order: pipe elbow, pipe, pipe elbow and down pipe. Leave a 10 mm clearance to compensate for thermal expansion of the pipe.

14

INSTALLATION OF DOWN PIPE JOINTS

Connect down pipes using the push-fit system. Leave a 10 mm clear­ance in a joint socket to compensate for thermal expansion of the pipe.

15

RAINWATER RECLAIMER

We recommend that a reclaimer should be installed in locations not subjected to serious pollution (e.g. tree leaves). In case the reclaimer cleaning is necessary, it should be flushed several times with pressur­ised water.

16

INSTALLATION OF CLEAN-OUT

A clean-out should be mounted on the lower down pipe section when a gutter system is to be connected to a sewer system. Each clean-out comes with a strainer collecting impurities from a gutter. The whole is closed with a tight lid. The passage between a 110 mm diameter clean-out and a 90 mm diameter pipe may be connected us­ing a reduction adapter.

17

INSTALLATION OF SEDIMENT TRAP

A sediment trap should be installed in the ground. It must be flushed with the final soil layer. In order to provide the necessary stability, pour concrete on an excavation bottom and connect the sewage system piping. After the final soil level is established, pour another layer of concrete around the sediment trap. Next, connect a down pipe.
