Important information

• Before installation, carefully read these Instructions and follow the installation procedures and guidelines of the Occupational Safety and Health Agency (OSHA). It is recommended to use personal protective equipment when moving and working on the roof. Such equipment includes fall protection measures and personal protective equipment such as gloves, safety glasses, safety helmets and safety harnesses, etc. Avoid contact with sharp edges of metal sheets. Metal sheets and PVC products are recyclable. They should be disposed of at a point for separate collection of waste after the end of the product life cycle.
• Installation of the system by following the instructions below guarantees the correct and reliable operation of the STEEL SAXON STEEL Square Gutter System.
• The STEEL SAXON STEEL Square Gutter System must not be installed at a temp. below 0°C.
• The steel material from which the gutter system is made requires thermal elongation of the system components to be taken into account. Properly designed and installed fittings ensure correct compensation of the temperature of long components.
• The system mounting components (gutter hooks, steel clamp) allow the gutters and drain pipes to move freely.
• It is recommended to store the system in its original packaging and in a shaded place until installation.

1. Preparation of the roof structure and installation of hooks

To install the STEEL SGS correctly, cut the rafters to length in the proper manner.

Plan the positioning of the gutter relative to the roof end so that the line marked as its extension is 10–20 mm above the outer edge of the gutter. The above positioning should protect the gutters from the impact of snow sliding down. If it is not possible to follow the above guideline, snow fences must be installed on the roof to reduce the risk of the gutter sustaining damage from snow sliding down.

The recommended hook spacing for the STEEL SGS is up to 50 cm.

2. Determining the correct gutter slope

When positioning the hooks for the STEEL SGS, the correct gutter slope must be taken into account. To this end, the gutter must have a slope towards the discharge funnel of approximately 0.3% (i.e. 3 mm per 1 metre of gutter). To achieve the correct slope, the hook furthest away from the funnel must be installed first, followed by the hook next to the discharge funnel. We recommend using string when determining the installation location for the other hooks.

Correctly installed hooks will prevent the system from leaking at the gutter joints.

3. Determination of the position and preparation of the opening for the drainage funnel

An equally important step in the installation of the STEEL SGS is determining the position of the discharge funnel, which is the lowest point of the system. The hooks must be installed not further than 15 cm from the edge of the discharge funnel and other gutter fittings such as the universal parts, i.e. the connector, the bottom and the corner.

Once the location of the discharge funnel has been determined, a square opening must be cut in the bottom of the gutter, corresponding to the drain pipe dimensions of 80x80 mm. The edges of the opening must be bent according to the direction of water flow.

The discharge funnel must be installed at the location of the cut-out opening, and then the mounting leaves must be bent onto the gutter beads.

4. Gutter connector installation

Remember to apply gasket spray prior to installing the STEEL SGS gutter fittings. Next, properly trim both ends of the gutter so that their edges fit precisely into each other. This will ensure the stability of the entire structure. Then, place a union on the connected ends of the gutter to form a permanent and watertight connection.

1. Fit the connector from the bottom, evenly, so that the gutter radii are firmly in contact with the connector radii.
2. Press the rear parts of the gutters so the back sits correctly. The connector must be flush with the rear of the gutter.
3. Bend the rear ears of the fitting against the gutter bead.
4. Put the clamp onto the front bead of the gutter and bend the leaf on the clamp.
5. If necessary, tighten the fitting to the face board at the mounting hole.

5. Installation of the universal bottom

Universal bottoms must be installed at the ends of the gutters, and attention must be paid to the correct positioning of the gasket. Roofing sealant should be used to improve the system’s tightness.

1. Bend away the upper leaves of the bottom.
2. Insert the lower part first, followed by the upper part.
3. Bend the leaves over the gutter bead.
4. Screw in the bolt in the mounting hole.

6. Installation of (universal) inner corner

Silicone sealant spray should be applied before STEEL gutter pieces are assembled. Next, both ends of the components should be cut accordingly so that one end fits precisely into the other. Then place a union on the joined ends to form a sealed and secure connection.

1. Fit the connector from the bottom, evenly, so that the radii of the gutter and corner are in firm contact.
2. Press the rear parts of the components so that they settle properly in the connector.
3. Bend the rear ears of the fitting over the gutter bead.
4. Put the clamp onto the front bead and bend the leaf over it.
5. If necessary, tighten the fitting to the face board.

7. Installation of the (universal) outer corner

Silicone sealant spray should be applied before STEEL gutter pieces are assembled. Next, both ends of the components should be cut accordingly so that one end fits precisely into the other. Then place a union on the joined ends to form a sealed and secure connection.

1. Fit the connector from the bottom, evenly, so that the radii match.
2. Press the rear parts so they align correctly.
3. Bend the rear ears of the fitting against the bead.
4. Attach the clamp and bend the leaf over it.
5. If necessary, tighten the fitting to the fascia board.

8. Installation of the downpipe

Connect the discharge funnel to the pipe using an elbow joint, or directly to the drain pipe (for eavesless roofs).

To install dowels in the façade, choose dowel length according to insulation thickness. Install clamps on the dowels with a maximum spacing of 1.8 m. If the pipe riser exceeds 4 m, use an additional clamp below the pipe connector.

Place the pipes in the clamps, ensuring enough pressure when screwing to allow free thermal movement.

9. Completion of the installation

To discharge water from the STEEL SGS into the sewerage system, a universal settling tank must be placed in the ground under the drain pipe. Cut an opening in the flap of the tank matching the pipe size and insert it. To drain to the ground, an elbow must be installed at the end of the drain pipe.

10. Overlapping installation

The alternative installation of the universal corner starts with notching the gutters and removing the inner gutter folds. The prepared gutter is pushed into the inner profile of the corner. Then place the gutter connector on the formed joint and follow the correct order of assembly steps:

1. Fit the connector from below, evenly, so that the radii of the gutter and the corner are firmly in contact with the connector.
2. Tighten the rear ends so they align properly.
3. Bend the back ears of the fitting against the gutter and corner.
4. Attach the bracket to the front and bend the leaf.
5. If necessary, tighten the fitting to the end board.
