EN 50379 REGULATED INSTRUCTIONS
EN 50379 Section 4 .3 .2 “Instructions” defines a number of specific points that must be included in the relevant instruction manuals .
The paragraph numbering below relates to that section of EN 50379 .
a) The C165 is compliant the EN 50379 Part 2 and Part 3 .
b) The C165 is intended to be used with the following fuels:
Natural gas, Propane, Butane, Light oil (28/35 sec), Wood pellets, Town Gas, Coke Gas, Bio Oil, Bio Gas
c) The C165 is designed for use with either non-rechargeable alkaline AA cells or rechargeable NiMH AA cells . Four cells are needed . Types
cannot be mixed . Under no circumstances should any attempt be made to recharge alkaline cells .
The battery charger supplied with the C165 is rated for indoor use only . Its voltage input must be in the range 100 – 240V AC at 50 – 60Hz
with a current capability of 0 .3 A . The chargers output voltage is 9V DC at a maximum of 0 .66A .
The charger has no user serviceable components .
Only a correctly specified and rated charger must be used with the C165 .
d) The C165 is not designed for continuous use and is not suitable for use as a fixed safety alarm .
e) An explanation of all the symbols used on the analyzer’s display is given in Display Parameters Pg . 8 of this manual .
f) The recommended minimum time required to perform one complete measurement cycle and achieve correct indication of the measured
values in EN 50379 Part 2 is 110 seconds . This is based on the T90 times defined in the standard, always assuming that parameters being
measured have reached stability . This time is the summation of the times for a draught test (10 secs) and a combustion test (90 secs) plus
the time to move the hose connection from the pressure input to the water trap (10 secs)
g) The recommended minimum time required to perform one checking procedure in EN 50379 Part 3 is 110 seconds as described in section f)
above .
h) Some commonly occurring materials, vapor or gases may affect the operation of the C165 in the long or the short term though in normal
use UEi is not aware of any specific issues that have affected the product . The following list is included to satisfy the stated requirements
of EN 50379: Solvents, Cleaning fluids, Polishes, Paints, Petrochemicals, Corrosive gases
i) The C165 is fitted with an electrochemical CO sensor and an infra-red CO
2
sensor which have an expected life of more than 5 years . The
calibration of these sensors must be confirmed on an annual basis . The batteries have an expected operational life of more than 500 re-
charge cycles .
j) The C165 is designed to operate at ambient temperatures in the range 32°F to 113°F with relative humidity of 10% to 90% non-condens-
ing . While it is recommended that the analyzer is given the protection of a carry case during transportation it is not required for normal
operation .
k) The C165 has an initial start-up delay following switch on of between 90 and 60 seconds dependent on ambient temperature . There is no
additional delay after battery replacement .
l) Most sensors used in combustion analyzers give a zero output when they fail, and it is widely recommended that analyzers are regularly
checked (also known as a bump test) using either a can of test gas or a known source of combustion products .
The C165 must have its calibration checked on an annual basis and be issued with a Certificate of Calibration .
The sensor within the C165 can only be replaced by UEi Test Instruments .
The water trap should be checked on a regular basis while the analyzer is in use (every few minutes) as the amount of condensate gener-
ated varies with the fuel type, atmospheric conditions and the appliances operating characteristics .
The particle filter should be checked at least on a daily basis when using ‘clean’ fuels and more often when using liquid or solid fuels .
Detailed instructions regarding the changing of the filter and the emptying of the water trap are given in “Before Using the Analyzer” Pg . 7
of this manual .
m)
WARNING!
When using a C165 to test an appliance a full visual inspection of the appliance, in accordance with its manufacturer’s instructions, must
also be carried out .
