STARTING UP AND REGULATION WITH METHA-

NE GAS

1) If not already done at the moment of connecting the burner to

the gas pipeline, it is indispensable to carry out a purge of the air

contained in the pipeline. As a precaution, special care should be

taken and doors and windows should be opened. Open the pipe

union on the pipeline situated near the burner and then open

a little the gas cut-off cock (or cocks). When the characteristic

odour of gas can be smelled, close the cut-off cock. Wait until

the gas present in the room has dispersed, and then reconnect

the burner to the gas pipeline. Subsequently, re-open the gas

cut-off cock.

2) Check that there is water in the boiler and that the system’s

gate valves are open.

3) Check, with absolute certainty that the discharge of combustion

products can take place freely (boiler and chimney lock-gates

should be open).

4) Make sure that the voltage of the electric line to which the burner

is to be connected, corresponds to that required by the burner

and that the electrical connections (motor or principle line) have

been prepared to match the voltage rating available. Also check

that all the electrical connections carried out on the spot are in

accordance with our electric wiring diagram.

5) Make sure that the combustion head is long enough to enter

the furnace to the extent specified by the boiler manufacturer.

6) Remove the protection cover from the disk carrying the air and

gas flow regulator screws and slacken the screws that block

the regulator screws.

7) Check that the air regulator device on the combustion head is in

correct position for the fuel throughput required (the air passage

between the diffusor disk and the head must be small for low

throughput and relatively wide when throughput is higher). See

“Combustion head airflow regulation” heading.

8) Fit a pressure gauge with suitable full scale (where the pressure

level envisaged allows, a liquid manometer is preferable; do not

use pointer gauges for low pressures) to the pressure outlet

port on the gas pressurestat.

9) Open, as far as considered necessary, the flow regulator

incorporated in the pilot flame valve(s). Also check that the

combustion airflow control shutter is sufficiently open; if neces

-

sary, alter the position by acting on the regulator screws on the

regulator disk.

10) With the burner panel switch on “O” and the master switch in

‘make’, that the fan motor rotates in the correct direction. If

necessary, reverse two phases of the motor power supply line

to change the direction.

11) Now switch the panel switch to “I” and turn the modulation

switches to MIN (minimum) and MAN (manual). With the

control system receiving electrical power, the programmer

will  cause  the  burner  to  start  up  as  described  under  the

foregoing heading “Description of natural gas operation”.

During pre-purge time, check for operation of the air pressu-

restat, the contacts of which should change from a pressure-

zero ‘make’ to a pressure-positive ‘make’. In the event that the 

pressure is sufficient and the pressurestat fails to respond, 

neither the ignition transformer nor the pilot flame gas valves 

will operate so the burner will shut down in lockout.   

Note that lockouts during this first ignition sequence should be 

considered normal since the fuel supply line will still contain air 

which must be purged before a stable flame can be obtained. 

Press the “reset” button to re-start.

UV Cell 

If  flame  detection  is  carried  out  with  the  UV  cell, 

the following should be taken into consideration. 

Even the slightest greasiness will compromise the passage 

of the ultraviolet rays through the UV photoelectric cell bulb, 

thus preventing the sensitive internal element from receiving 

the quantity of radiation necessary for it to function properly. 

Should the bulb be fouled by light oil, fuel oil, etc., it is in-

dispensable to clean it thoroughly. It should be pointed out 

that even by simply touching the bulb with the fingers, it is 

possible to leave a slight greasiness which could compromise 

the working of the UV photoelectric cell. The UV cell does 

not “see” daylight or light from an ordinary lamp. It is pos-

sible to verify its sensibility with a flame (or cigarette lighter 

or a candle) or with the electric spark that occurs between 

electrodes in an ordinary ignition transformer. 

To ensure that the UV cell works properly, its current value 

should be sufficiently stable so as not to fall below the minimum 

value required for the specific control box. It may be necessary 

to search experimentally for the best position by sliding  (axial or 

rotation movement) the body that contains the photoelectric cell 

in respect to the fastening clamp. An inspection can be carried 

out by inserting a microammeter, with an adequate scale, in 

series to one of the two UV photoelectric cell connection wires. 

It is obviously necessary to respect the polarity (+ e -). The 

minimum cell current value, to ensure the correct operation of 

the control box, is shiwn on the wirung diagram.

12) As soon as the burner is ignited at low flame (main flame valve

open and modulator on minimum) make a visual inspection

of the strength and appearance of the flame, making any

corrections required (adjust the gas or air regulator screws on

the modulating disk). The next step is to take a meter reading

of the volume of gas put through the burner (see the “Meter

Reading” section). If necessary, a further correction in the

gas flow may be made as described above. Once fuel and

air flow are satisfactorily regulated, a check must be made on

combustion characteristics, using the appropriate instruments.

If the air/gas ratio is correct the level of carbon dioxide (CO2)

per unit of fuel put through should be approximately - in the

case of natural gas - 8% at minimum burner output, rising to

an optimum 10% at maximum output. We recommend that

the value of 10% should not be exceeded, as operation in too

limited an excess of air can give rise to unacceptable carbon

monoxide (CO) levels (due to variations in atmospheric pres-

sure, or dust deposits in the air lines). It is essential to verify,

using the appropriate instrument, that the percentage of CO

in flue gases does not exceed the maximum permissible level

of 0,1%.
