1. General Description
The bird guard consists of a heavy guage wire mesh“box”designed to mount on top of a wide range of chimney pots and to insulated chimneys. All fittings and“jubileeclip” clamp band are made of stainless steel for corrosion resistance and long life.
An alternative flat fixing kit is available for mounting the guard on chimneys without pots.
Models are supplied in 25mm mesh for wood / coal fires and 12 mm mesh suitable for gas / log effect fires to comply with BS 5871 pt.3.
Also available fitted with a stainless steel rain cap.
2. Health & Safety
Cut edges of stainless steel can be sharp. Leather gloves are recommended when handling and fixing the bird guard.
Access to chimney terminals will involve the use of ladders and / or scaffolding. Attention is drawn to safety rules and codes of practice in the use of ladders and access equipment (Download the PDF from the HSE here). Work involving gas fires & flues must only be carried out by a Gas Safe Registered installer.
3. Tools required
6mm screw driver, sheet metal snips, light hammer.
The base of the guard can be shaped to fit either round or square pots. The guard is supplied with 4 downward pointing stainless steel lugs approximately 225mm long. Bend these outwards and downwards over the top-most rim, bead or louvre of the pot as appropriate. Fit the jubilee clip immediately below the rim, bead or louvre to clamp the lugs firmly against the side of the pot. Then bend the lugs outwards at right angles to the pot and snip off all but 20mm of the projecting portion of the lugs.
With a light hammer, tap these projecting lug ends upwards and inwards against the outside of the jubilee clip. Gently tighten the jubilee clip, but do not over tighten as this may damage the thread.
The guard is now firmly secured in position.
Bishop & Marcone pots – insert the lugs down the insideof the upper crown / cone top and secure just below the louvre slots as above(Marconemodels are supplied with longer lugs). Use a similar technique when fitting to a factory made insulated chimney.
If flat fixing lugs are supplied, these should be screwed and plugged to the masonry with the stainless steel screws provided. Use either the inner or outer holes as appropriate. A bead of silicone mastic between the bottom edge of the mesh and the masonry will reduce rain ingress.
