Burner start procedure 

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 (shutter & band) for 
input fi ring rate. Check the manufacturer’s settings 
either on the nameplate shown in Figure 1 or 
listed in Table 2. If adjustment is necessary refer to 
Figure 11 and loosen the adjustment screws then 
twist the shutter and/or air band until the indicators 
point to the values shown on the nameplate or 
listed in Table 2.  
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.

Clock the meter for CFH and calculate the 
input fi ring rate. Compare the calculated rate to 
the specifi ed input for the boiler found on the 
specifi cation sheets and on the rating plates for 
the burner and boiler. Do not exceed the specifi ed 
maximum input for the boiler. 
Attach a manometer to the manifold test port, clock 
the meter, and adjust the regulated pressure until the 
specifi ed input level is achieved. Refer to Table 2.
Be sure to set the breech or furnace pressure to the 
correct value, since this will have an effect on the 
manifold pressure.

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.
