every boiler in the system has its individual safety controls
intact and operational, even if the firing of the boiler is under
control of the master boiler.
In the event that the system sensor fails, all boilers in the
system will ignite simultaneously when there is a demand, and
each boiler will individually regulate firing rates to maintain
the master set point temperature (tank set point + installer
#4) at the individual supply sensors built into the boiler. If
this should happen, the master boiler will display an E03 fault
code, indicating that the supply sensor has failed.
L. Cascade System Programming
1. If the boiler is used alone, skip this section.
2. Programming the Master Boiler:
a. Make sure there is no demand for heat being supplied
to the boiler.
b. Apply power to the boiler.
c. Enter the system setting program navigation following
instructions in Part 10 of this manual.
d. Verify that cascade address function 15 is set to 0. This
makes the master boiler address 0. NOTE: The Master
Boiler MUST be addressed as 0.
e. Change Cascade Mode function 23 to ALL 926 if cascade
system IS NOT common vented. If cascade system IS
common vented, set Function 23 to the total number of
boilers in the system (4 BOILERS for a four boiler system,
6 BOILERS for a six boiler system, etc.)
f. Exit the installer menu.
3. Programming Follower Boilers:
NOTE: READ THE NOTES BELOW BEFORE
PROGRAMMING FOLLOWER BOILERS
•
The boiler addressed as 1 will share its alarm output
with the master boiler.
•
If one of the follower boilers has an indirect fired water
heater connected to it, the address of this boiler must
be 2 or greater.
•
It is recommended but not necessary to address boilers
in the order that they are wired.
•
No two boilers can have the same address.
•
It is not required to use all consecutive address
numbers. Example: In a 2 boiler system with an indirect
connected to the follower, the follower address would
be 2 (address 1 is not used).
•
Maximum amount of boilers in a cascaded system is
eight (8).
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. This establishes the boiler as a follower in a cascaded
system and enables data to be transferred as needed for
the system to function at full capability.
NOTE: ONLY select number 8 IF you are using a Vision 3 panel
for cascade operations instead of a master boiler.
e. Change "CASCADE MODE" Function 23 to parameter
to "ALL 926" if the cascade system is not to be common
vented. If the cascade system IS to be common vented, set
Function 23 to "COMMON FLUE".
f. Exit the installer menu.
Part 9 - 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.
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.
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.
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.
