5.3
Commissioning the Burner - GAS HEATERS
Follow section 5.1.1 to 5.1.2.2 for preliminary checks.
Note: Ecoflam
High/Low
and
Modulating
burners have extra specific requirements. Follow the manufacturers
instructions using the setting data provided in these instructions in section 2.
It is important when setting the minimum firing rate to check on site that the flue temperature does not fall below 150°C
when running for prolongued periods of low fire. The minimum firing rate must be increased above the minimum stated
in the data tables to ensure this situation. Failure to take acount of flue temperature will cause the combustion products
to condense. This will cause water leakage problems and heat exchanger life problems.
5.3.1
Preparation of the Burner
Ensure the burner head, air damper and pressure switch settings are adjusted in accordance with the Data Tables for
the correct burner (see burner reference letter on the data plate).
5.3.2
Carry Out A Dry Run
To prove the safe operation of the controls allow the burner to cycle without gas turned on.
With the gas service cock still in the off position, turn on the electric supply to the heater and observe the burner
operation as it goes through the cycle of events.
5.3.3
Switching On
Operate the external controls to turn on the heater (Heat ON position). If the lockout reset button on the burner control
box is illuminated, press in to reset.
Note:
The burner plug and socket may be used to turn the burner off and on during commissioning.
After a short delay the combustion air fan should run. (see Section 2 for full sequence times).
After the purge period, the electric ignition will turn on (this can usually be heard as a crackling sound at the burner),
followed quickly by the start gas valve (Main Gas Valve for models 15 to 30) opening.
The control box will now go to lockout as no flame will be present.
If the control box goes to lockout after 5 seconds of the purge period, this may be due to the air pressure switch being
set too high, (turn it's adjustment down slightly), or the burner fan not being connected correctly (see Burner
Manufacturers Instructions and reset the lockout button).
Before continuing with the commission carry out the gas valve proving tests described in the Burner Manufacturers
Instructions.
