INSTALLATION OF GUTTERS

THE BRETT MARTIN CAST IRON STYLE GUTTER SYSTEMS ARE SPECIALLY COATED VERSIONS OF THE EXISTING RANGES AND FOLLOW THE USUAL INSTALLATION PROCEDURES AS STANDARD PVCU SYSTEMS.

GUTTER INSTALLATION

Brett Martin Rainwater gutters can be efficiently installed if the following procedures are followed. Rainwater systems are supported by the outlet joint/union bracket and external angles as well as the gutter support brackets, all of which must be fixed, wherever possible to the fascia or support bracket. Alternatively the rainwater system can be securely held by rise and fall brackets, to ensure troublefree lifetime service.

INSTALLATION SEQUENCE

Position the gutter outlet vertically above the drain inlet or gully from which the rainwater will be conveyed to the underground drainage system.
Fix the outlet in position on the fascia allowing for whatever fall, if any, is required.
Fix the gutter support bracket furthest from the outlet at a position on the fascia which will produce a run of gutter either horizontal or to the desired fall.
Stretch a line taut between the fixed outlet and support bracket, establishing a straight gutter line.
Fix the remainder of the fittings to the fascia following this line, a joint bracket being positioned at each junction of two gutter sections.
Where, due to the absence of a fascia or the design of the building support fittings cannot be fixed, the rafter top bracket and side bracket provide alternatives.
Rise and fall brackets driven into the wall will support the gutter system where there is no fascia and rafter brackets are impractical. Position these against alternate sides of joint brackets, running outlets or angles along the installation to prevent excessive thermal movement in any one direction.

GUTTERING SUPPORT SPACING

Gutter support spacing should normally NOT EXCEED 900mm. Roofs with a pitch exceeding 35° and/or with SMOOTH SURFACES and/or are subject to HEAVY SNOW LOADING, support spacing should NOT EXCEED 600mm. Various gutter angles incorporate fixing positions which can be drilled for fixing. If the angle is fixed to the fascia board, adjacent support brackets should be no more than 900mm away. If the angle is not fixed the brackets should be no more than 150mm away.
