is running, the flue gas CO
2
should be measured, refer to section 6.1,
and compared to the values stated in Performance Data, section 2.2. If
the measured value does not correspond to the Performance Data, then
follow section 9.3.1 below or contact: Halstead Glen Dimplex service

GAS VALVE REPLACEMENT INSTRUCTIONS
The Eden VBX 18 and 30 are category II
2H3P
appliances.
The appliances are supplied for use on Natural Gas (G20) at a supply
pressure of 20 mbar or Propane (G31) at a supply pressure of 37 mbar
but can be converted from NG to Propane or vice versa, using specific
conversion kits. They are certified to comply with the requirements of
EN 483 for use in GB and IE only.
It is the law that all gas appliances are installed and
maintained by a competent person such as a Corgi
registered installer, in accordance with the rules in force.
It is in your own interest, and that of safety, to ensure that
the law is complied with. Failure to do so could lead to
prosecution.
The following instructions are intended for guidance and
in no way override any Statutory Requirements.
a)
The combustion values at minimum gas rate and maximum gas rate
must be checked using a suitably calibrated Flue Gas analyser.
Compliance with BS7967-2, BS7967-3 and BS7967-4 is required.
b)
Do not attempt to adjust the gas valve unless you have a suitable
Flue Gas analyser that is checked and within calibration.
Compliance with BS7967-2, BS7967-3 and BS7967-4 is required.
