However, the fuel bed material may be prone to causing
problems with incomplete combustion of the gas and
potential generation of carbon monoxide, or sooting as
described by the manufacturer. In that case, the warranty
would not apply and the plumber/gasfitter would have to
resolve the problem.
The gas entry point for this appliance was shown in one
drawing to be at the lower right corner near the base, yet in
the very next drawing it appears to penetrate the top right
hand panel.
PRESSURE TEST POINTS:
Interestingly the manufacturer has called up the
requirements of AS/NZS 5601 – 2013 in reference to
pressure test points required and their location.
As previously, Victoria and NSW had not adopted AS/NZS
5601- 2010 and in that edition of the Standard there was
the requirement for the gasfitter who is either laying a new
gas fitting line or is installing an appliance to fit a test point
on the gas fitting line prior to any gas appliance where one is
not normally available.
I cannot be sure how many plumbers/gasfitters are aware
of some of the latest requirements for the location of test
points or have looked at the following two clauses that
introduce some new requirements
Clause 2.4.10 Pressure test points:
“Adequate pressure test points shall be provided to
ensure all parts of the gas installation can be safely tested
and commissioned.
Clause 5.11.4 states that pressure test points shall be
accessible and provided at, or adjacent to, the:
∫ Outlet of gas pressure regulators installed in the gas
pipework;
∫ Inlet and outlet of pressure raising devices installed in the
gas pipework;
∫ Outlet of the venting device of a double block and vent
safety shut-off system;
∫ Inlet of the gas appliance if no appropriate test point is
incorporated in the gas appliance.
Where a permanent pressure gauge is fitted, a provision
to fit an alternative test point shall be provided.
Where pressures exceed 7kPa, pressure test points shall
be of the self-sealing type.
