Set Air Pressure Switch
WARNING:
SETTING OF THE AIR PRESSURE SWITCH MUST ONLY BE CARRIED OUT AS
PART OF A COMPLETE COMMISSION INCLUDING COMBUSTION TESTS.
See manufacturers information.
To set a pressure switch:
Remove the cover of the air pressure switch -
Note:
THIS EXPOSES LIVE TERMINALS.
With the burner firing as set up previously, turn the setting dial of the pressure switch to the setting indicated in the data
table for the model and burner reference concerned.
The pressure switches are designed to prevent the burner from producing dangerous combustion products under
adverse conditions such as reduced supply voltage and blocked flues.
It is important that the settings indicated in the Data Tables are used and any unexpected operation of the pressure
switches is fully investigated before any attempt to deviate from these settings is made.
5.3.10
Completion
After completing the commission, test fire the heater several times to ensure that it starts reliably and the safety and
automatic controls function correctly. Fill in the commissioning data sheet at the back of this manual with the recorded
settings and results. Ensure all the covers, caps and panels removed during commissioning are securely replaced.
High/Low or Modulating Burners.
Following setting the minimum firing rate a check must be made following the setting of the burner combustion .
The check is made by running the heater on low fire for a minimum of 15 minutes at the full transport air rate and at
typical ambient conditions.
During the test check that the flue gas temperature does not fall below 150°C .Should the flue gas temperature fall
below 150°C then the low fire gas setting must be increased to a value that will achieve 150°C flue gas
temperature,otherwise condensation may form in the heat exchanger and flue causing rapid corrosion and short
operational life.
5.3.11
Hand Over
Hand these instructions to the user (or leave them at the heater), and fully explain the use of the user controls. This is
to include:
Starting and stopping the heater.
Setting and operating the time switch.
Setting and operation of the thermostats (and their position).
What to do if the heater does not operate.
What to do if a gas leak is suspected.
The need for regular servicing.
Any other points regarding the installation that the user may need to know.
WARNING
Following commissioning operations, conversion to a different type of gas or adjusting the burner,
any seal on gas adjusters or limit temperature settings that has been broken must be re-made.
