2.9 FLUE CONNECTIONS | FLUE SYSTEM |
| The provision for satisfactory flue termination must be made as described |
| in BS |
| The appliance must be installed so that the flue terminal is exposed to outdoor air. |
| The terminal must not discharge into another room or space such as an |
| outhouse or |
| It is important that the position of the terminal allows a free passage of air |
| across it at all times. |
| The terminal should be located with due regard for the damage or |
| discolouration that might occur on buildings in the vicinity. |
| In cold or humid weather water vapour may condense on leaving the flue |
| terminal. |
| The effect of such “steaming” must be considered. |
| If the terminal is less than 2 metres above a balcony, above ground or above |
| a flat roof to which people have access, then a suitable terminal guard must |
| be fitted. When ordering a terminal guard, quote the appliance model |
| number. |
| A suitable terminal guard is available from: |

| The minimum acceptable spacing from the terminal to obstructions and |
| ventilation openings are specified in FIG. 2.6. |
