Start the Burner 
Initial Air Settings
If your burner was built for a specifi c OEM (Original 
Equipment Manufacturer) application, the “Mfr’s 
Settings” label (see Figure 1) will indicate the application 
and the initial air settings made at Beckett.  Please verify 
those settings using the following procedure.  
If your burner was not built for a specifi ed application, 
the following steps outline the procedure for initially 
setting the damper (these settings may be different from 
settings specifi c to a particular OEM).  
Refer to Figure 10A and 10B for this procedure.
Remove the cover screw (A) then the cover (B) and 
set aside.

plates, enclosures and guards are in place and 
securely fastened.
When available, refer to the appliance 
manufacturer’s instructions and install the burner 
accordingly.
6.  Test Instruments 
The following calibrated test equipment is required 
to properly install the appliance. Whether these are 
included in one kit or are individual test components, 
they should be calibrated and in good working order.
A combustion analyzer capable of measuring 
oxygen (or carbon dioxide), carbon monoxide, stack 
temperature, ambient temperature, and appliance 
effi ciency.  
Electrical multi-meter capable of measuring voltage, 
ohms, amps, and DC micro-ammeter for measuring 
the fl ame signal.  These could be included in one 
meter or separate meters, but should be calibrated 
and accurate.
Calibrated manometers and gauges capable of 
measuring all pressure ranges in the gas supply and 
appliance draft.  This could typically range from a 
few psi to 0.01” W. C. 
Having several manometers or U tubes with the 
correct range can simplify the testing and set up 
procedures.
 
Burner Start Procedure
(Before proceeding, turn off and lock out electrical 
power and close the main leak test cock to shut off 
gas to the burner.)
With the power and main gas supply to the burner 
turned off, make sure gas has not accumulated in 
the boiler or fl ues. 
Check the initial air settings for the input fi ring rate. 
Check the manufacturer’s settings either on the 
nameplate shown in Figure 1 or listed in Table 3
If adjustment is necessary refer to Figures 10A 
& 10B
 and set the damper motor cam so that 
the indicator points to the values shown on the 
nameplate or listed in Table 3.  
With the main gas supply valve closed. Set the 
limit or controller to call for heat then apply power 
to start the burner. Reset the high and low gas 
pressure switches if necessary. 
In order to check the function of each component 
(i.e: fl ame safeguard sequence, airfl ow proving 
switch, ignition transformer, gas valves, safety 
lockout timing, etc.), with the gas supply closed off, 
monitor a complete burner run sequence. Note that 
the fl ame safeguard control will lock out since the 
fuel supply has been closed off. 
If component operation sequence and function is 
correct, reset the fl ame safeguard and initiate a 
new cycle.  Monitor the start-up cycle and manually 
open the main leak test cock as soon as the fl ame 
safeguard powers the safety shutoff valves.  If the 
boiler room is quiet you may be able to hear the valve 
open, if not you can generally place your hand on the 
valve and feel it open.  After you have observed main 
fl ame for a brief time, trip any of the switches in the 
limit string to shut the burner down.  Monitor the fl ame 
and safety shutoff valves to assure that shutdown 
is controlled by the valves and that they operate 
properly.  With this test passed you may safely initiate 
automatic start-ups on subsequent cycles.

Professional Installation 
and Service Required
Incorrect installation and mishandling of start-
up could lead to equipment malfunction and 
result in asphyxiation, explosion or fi re.
This burner must be installed and prepared for start-
up by a qualifi ed service technician who is trained 
and experienced in commercial gas burner system 
installation and operation.
Do not attempt to start the burner unless you are 
fully qualifi ed.
Do not continue with this procedure until all items in 
the ‘Prepare the Burner for Start-up’ section have 
been verifi ed.
Carefully follow the wiring diagrams, control 
instruction sheets, fl ame safeguard sequence 
of operation, test procedures and all appliance 
manufacturer’s directions that pertain to this 
installation.
If any of these items are not clear or are unavailable, 
call Beckett at 1-800-645-2876 for assistance.
