Operation
Air and Gas Adjustment
for LE Models
The low emission burner can be best
described as a fuel staged, multi-radial
injection type. Two air/gas ratio electro
servo actuators control the fuel supplied to
this burner. A radial blade type fan supplies
the air. A direct-coupled reversing actuator
modulates the air which in turn regulates
the fuel input. No mechanical linkage is
utilized with this system. As a safety device,
a thermocouple is placed in the small partial
premix area of the burner to monitor
temperature. It is used in conjunction with a
temperature limit that should be set
between 600° and 700°F.
Commissioning/Start Up
for LE Models
WARNING
Commissioning/Start Up by a non-
Fulton authorized person will void the
product warranty.
Before commissioning the boiler, verify with
authorized personnel that the gas lines
have been purged.
SIEMENS LMV LINKAGELESS BURNER
MANAGEMENT SYSTEM
(If Equipped)
The Siemens LMV system is a fully
packaged burner management system,
linkageless control and first out annunciator.
When operating the Siemens LMV
systems, all changes are made through the
Siemens AZL display. The left and right
arrow keys are used for scrolling through
the menu and changing
parameters. Enter accepts the menu and
parameter changes.
It is possible to return to the main menu at

• Read the diagnostic feedback on the AZL
display, address the fault if possible.
• Press escape on the AZL once.
• Press enter on the AZL to reset the
control. The red light should go out.
If the fault persists contact Fulton.
If the boiler has a dual fuel burner, the
burner setup procedures on the following

LMV Control
for LE Models
The following procedure must be
repeated for each fuel the boiler is
equipped to operate on.
PRE-IGNITION STEPS
1. Verify the main burner switch is in the
OFF position. If the boiler has dual fuels,
verify the fuel selector switch is turned to
the correct fuel.
2. Supply power to the boiler. The AZL will
display "system test" and then move to
the main menu.
3. Select PWLogin, press Enter. Select
AccessServ. Press Enter. (This type of
step will be shown as PWLogin >
AccessServ for the remainder of this
section. Enter the service passwords
using the arrow key. The password is
case sensitive. The case of a letter can
be changed by pressing the other arrow
key. (For example, if you used the right
controller
arrow key to get to the letter A, press the
left arrow key to get a). After you have
pressed Enter on the last character of
the password, press Enter once more
to accept the password. If you do not
have the password, contact your Fulton
Authorized Representative to perform
the changes.

Select RatioControl. Press Enter. Select
ProgramStop. Press Enter. Change
the Program Stop to 44 Interv1 by using
the arrow keys. Confirm the change by
pressing Enter. This will set the burner
management system to a 'pilot hold'
setting.
Verify that the current value "curr" changes
to 44 Interv 1.
IMPORTANT
When commissioning this boiler, firing rate
must remain at low fire during first
4 hours of operation. The output may then
be increased 7% to 10% per hour, until a
firing rate of 75% is reached. The 75% firing
rate should be maintained for 3 to 4 hours.
