PRELIMINARY CHECKS
Before starting up the boiler check the following: - gas type and feed pressure; - gas valves closed; - the seals in the pipe fittings; -
gas pipe breather and input pressure; - that the cable complies with the diagram and the phase and neutral wires correspond; - that
the burner shuts down when the boiler thermostat opens; - the seal of the boiler furnace which prevents air from entering; - the
seal on the flue-boiler pipe fitting; - the condition of the flue (sealed, free from blockage, etc ).
If all these conditions are present, start the burner. The control device starts the motor to carry out prewashing of the combustion
chamber. During this prewash period (about 30 seconds) the device checks that air pressure is correct via the air pressure switch. At
the end, it supplies power to the transformer and opens the gas valves. The flame must be lit and stabilize within 3 seconds, which
is the device's safety time limit. Check to ensure the flame is lit before placing any control instrument in the flue. Adjust and check
the gas flow necessary for the boiler at the meter. Adjust the air flow according to the gas flow to obtain correct combustion.
IMPORTANT ADVICE
All adjustable parts must be fixed by the installer after making adjustments. Check flue combustion after each adjustiment. The
CO values must be approx. 9.7 (G20) 9.6 (G25 11.7 (13B) 11.7 (13P) axld the CO must be less than 75 ppm.

SATRONIC DLG 976 CONTROL INFORMATION SYSTEM
The SATRONIC DLG 976 control is a micro-processor control which provides information about the current opera-
tion of the burner and the cause of any faults. The information is available by reading the "flash code" at the red LED
within the lockout reset button as detailed below. By the use of additional monitoring equipment a short history of
recorded faults is also available. There are two types of additional monitoring devices available from Satronic Ltd. The
"satropen" is a small pocket reader designed to give a visual read out of status, flame current and supply voltage.
Computer software is available to allow access to the current information and stored data.
On burner failure the red LED is permanently illuminated for a period of approximately 10 seconds, followed by a
brief "dark phase", then one of the following flash codes will indicate the cause of the fault. This indication will repeate
as long as the lockout reset button is not reset.
