Example: In a 2 boiler system with an indirect connected to
the follower, the follower address would be 2 (address 1 is not
used).
a. Make sure there is no demand for heat being supplied to the
master boiler
b. Apply power to the follower boiler you are working on.
c. Enter system settings following instructions in Part 10 of this
manual
d. Set cascade address parameter 15 to 1 for the first follower, 2
for the second follower, etc. depending on which boiler you are
programming based on the above notes.
e. Change “CASCADE MODE” parameter to “926 BOILRS”. This makes
the boiler a follower boiler and enables all data to be transferred
between boilers as needed for the system to function to full
capability.
f. Exit the installer menu.
NOTE:
The temperature set point of the follower must match the
master boiler set point in order for the system to operate properly.
Part 10 - Start-Up Procedure
FOR YOUR OWN SAFETY READ BEFORE OPERATING
1. This boiler does not have a pilot. It is equipped with an ignition
device which automatically lights the burner. Do not try to light the
burner by hand.
2. BEFORE OPERATING: Smell all around the boiler area for gas. Be
sure to smell next to the floor because some gas is heavier than air
and will settle on the floor.
3. WHAT TO DO IF YOU SMELL GAS
• Do not try to light any boiler.
• Do not touch any electric switch, do not use any phone in your
building.
• Immediately call your gas supplier from a neighbor’s phone.
Follow the gas suppliers’ instructions.
• If you cannot reach your gas supplier, call the fire department.
• Turn off the gas shutoff valve (located outside the boiler) so
that the handle is crosswise to the gas pipe. If the handle will
not turn by hand, don’t try to force or repair it, call a qualified
service technician. Force or attempted repair may result in a
fire or explosion.
4. Do not use this boiler if any part has been under water. Immediately
call a qualified service technician to inspect the boiler and to replace
any part of the control system and any gas control that has been
damaged.
5. The boiler shall be installed so the gas ignition system components
are protected from water (dripping, spraying, rain, etc.) during boiler
operation and service (circulator replacement, condensate trap,
control replacement, etc.)
Failure to follow these instructions could result in property damage,
serious personal injury, or death.
A. Control Overview
The control is one of the primary safety devices of the boiler. It monitors
the safety sensors of the boiler to assure safe and efficient operation.
The control has many features associated with system design. This
section addresses programming features, including Boiler Settings /
System Settings / Maintenance Settings and System Diagnostics, to
help in customizing your control. It is important to fully understand
control capabilities before customization, as its factory defaults may
already fit your system design and not require any adjustment at all.
C. Operating Instructions
Before operating the unit, it is important to remove the cover and
verify that the gas line and water lines are connected to boiler and
fully purged. If you smell gas, STOP; Follow the safety instructions
listed in the first part of this section. If you do not smell gas, follow
the next steps.
1. Turn down the thermostats before applying power to the boiler.
If 0–10 volt or other inputs are used, make sure that they are set so
there is no call for heat while programming.
2. Turn on the power to the boiler or boilers if a cascade system used.
3. Next, check the boiler settings. Adjustment and factory defaults
are outlined within this section. If a cascade system is used, it is
important that all the boilers have the same boiler settings.
4. Next, check the system settings. Adjustments and factory defaults
are outlined within this section. If a cascade system is used, it is
important that the Master Boiler is programmed with the correct
system settings.
5. Create a demand on the boiler or boilers if a cascade system is
used. The user can monitor system functions when the boilers are
operational.
6. If the boilers fail to start, refer to the troubleshooting section in
the back of this manual.
If you discover any evidence of a gas leak, shut down the boiler at
once. Find the leak source with a bubble test and repair immediately.
Do not start the boiler again until the leak is repaired. Failure to
comply could result in substantial property damage, severe personal
injury, or death.
B. Navigation of the Display
The display includes a two line backlit LCD readout to provide
informative messages about the operation of the boiler. Many
operating parameters can be viewed and adjusted by using the six
buttons on the display. The function of each button is described
below.
RESET
– The RESET button has two functions.
– Resets any lockout error code
– Returns the user to the default display screen.
ENTER
– The ENTER key is used to access parameter programming
mode. To access this mode, hold down the ENTER key for more than
4 seconds. The readout will change to:
One of the zeroes will be blinking. Use the
^ v
arrow keys to change
the blinking digit to the correct value. Use the
< >
arrow keys to
select the next digit to change and again use the
^ v
keys to change
the value. Repeat until the correct code is entered. Press the
ENTER
key to accept the code entered. If the code is correct, the readout
will change to the appropriate screen. If the programming code is
not accepted, the readout will continue to display as shown above.
ENTER
is also used to enable a function for editing. After the user
navigates to the desired function, the user holds down
ENTER
for
one second. When
ENTER
is released, the function value will begin
to blink. The function can now be changed using the
^ v
keys.
After the new value is displayed, the user then presses
ENTER
for
1 second to lock the new value of the function. The value will then
stop blinking.
LEFT AND RIGHT ARROW KEYS
–
< >
are used to navigate between
the default display, status display, analog and cascade displays if
they are enabled. The
< >
keys are also used in programming modes
to change between programmable functions. It is recommended
you use the Menu Maps in the back of this manual and the detailed
menu instructions printed in this section to help in menu navigation.
UP AND DOWN ARROW KEYS
–
^ v
are used to navigate between
the various functions displayed in the menu. After the function is
enabled for editing by pushing the
ENTER
key, the
^ v
keys are used
to adjust the function upward or downward to the desired value.
