INSTALLATION INSTRUCTIONS

SITE REQUIREMENTS

6. WIND PRESSURE ON BUILDINGS

6.1 Flues should not be terminated in a high pressure area.

7. TERMINATIONS

7.1 The most appropriate cowl depends entirely on conditions at

the site. Several may have to be tried before one is found

that gives good all-year performance. In some circumstances

it may not be possible to entirely exclude down draughts

caused by surrounding buildings or trees, so fit an anti-down

draught cowl, preferably of the OH type. A ‘Chinaman’s Hat’

is not sufficient and a GC 1 type cowl must not be fitted.
