What if the pipe is not
copper? If your existing gas
pipework is made from malleable iron there may be difficulty adjusting it for
length or height unless a thread is available to adapt to. Special equipment,
not normally used for domestic installations, is necessary to cut new threads
onto steel pipework. It cannot be soldered nor can a compression fitting be
used. With regard to gas
pipework, is there anything else that could cause a problem? If original pipework is
emerging from a solid wall or floor it should be inspected to ensure that it
is protected from corrosion. An inspection can usually determine if the
pipework was originally wrapped in an anti-corrosion tape such as Denso. If original gas
pipework was made from lead, regulations now prevent a gas fitter making any
new connection to it. The pipework would have to be replaced. Does the installer have to
do any work other than just connect the cooker? After connection of the
appliance to the gas supply, the gas engineer must undertake two mandatory
gas pressure tests. It is a CORGI requirement that these tests are carried
out every time any new gas appliance is installed or commissioned, to ensure
your safety. The first test is to
prove that there are no gas leaks in the premises, or on components before a
shut-off valve on any gas-burning appliance in the household. The second test is to
prove that the meter gas pressure regulator is operating correctly and that
the addition of a new gas-burning appliance has no detrimental impact on
other gas-burning appliances in the building such as causing a dangerous drop
in pressure. Once the tests are
complete the cooker can be commissioned and demonstrated. What will the installer do
during the tests? One of the tests will
require all other gas using appliances in the premises to be turned off; the
second test will require them to be fully turned on again. The second test
may highlight faults in other appliances such as ignition or combustion
difficulties that were previously unnoticed- everything is geared towards
your safety. What if the installer
finds a problem? The gas engineer should
fully explain the nature of the tests and any faults found should result in
the issue of a notice stating the exact fault and what needs to be done to
remedy it. If a gas engineer is
unable to obtain a correct working pressure for the cooker, it is an
indication that gas pipework, or the meter is undersized for the “load” being
placed upon it or that the meter regulator is faulty. More often than not,
problems are due to additional appliances being installed over the years
without the gas meter or associated pipework
being upgraded to cope with the new demand. |
