Notes:
* Additional external pipework and fittings may affect the resistance and must be taken into account on
installation.
** The nominal burner pressure should be 12.5 mbar and will only be obtained if the appliance inlet pressure
is correct at 20 mbar even when the appliance is running at full heat input. The meter should be capable of
passing 3 m∆/h of natural gas plus the requirements of any other gas appliances. See also Section 3.2, page
12.
Conversions: kW to Btu/h = kW x 3412.14, m∆/h to ft∆/h = m∆/h x 35.31, mbar to in wg = mbar x 0.4
