Note that in England and Wales the Building Regulations require a terminal guard to be fitted if the terminal is less
than 2m from the level of any ground, balcony, flat roof or place to which any person has access and which
adjoins the wall in which the outlet is situated. A suitable guard is available from Robinson Willey Ltd.
The Part No. of the guard is 994371.
In Scotland, although the Building Standards (Scotland) do not require a terminal guard to be fitted, the fitting of a
guard as detailed above is considered good practice.
Inside:
1. Allow 100mrn (4in) access at each side of the heater and a minimum distance of Il5mm (4.5in)beneath
the heater.
2. Curtains must be 15Omm (6in) clear at the top of the heater and 5Omm (2in) at the sides.
3. A good position for fitting the heater is below a window in order to minimize the effect of high heat losses and
cold draughts usually associated with glazed areas and to utilize wall space not normally occupied.
4. The distance between a shelf fitted above the heater and the top of the heater must not be less than15Omm
(6in). The shelf must not project more than 15Omm (6in.) from the wall.
5. Check the wall thicknesses. Three different sizes of flue are available for wall thicknesses up to 500mrn (20in.)
as shown below:
The standard flue is packed with the heater, the other lengths must be ordered specially (see specification-page 2)
