Ensure the boiler is full of water before firing the burner. Failure to do
so will damage the boiler. Such damage IS NOT covered by warranty,
and could result in property damage, severe personal injury, or
death.
3. Fill condensate trap with water.
4. Verify electrical connections are correct and securely attached.
5. Inspect exhaust vent and intake piping for signs of deterioration
from corrosion, physical damage or sagging. Verify exhaust vent and
intake piping are intact and correctly installed per Venting Section and
local codes.
6. Ensure both boiler power switches are activated before running the
unit.
J. Cascade System - 1000 and 1700 Models
This boiler assembly is shipped factory preset to operate as a common
vented cascaded unit. If the boiler is meant to be used as a common
vented cascaded unit and additional boilers are not to be added to the
system, skip this section.
Programming the Master Boiler:
a. Pick one of the bottom boilers to be the Master Boiler.
b. Make sure there is no demand for heat being supplied to the
boiler.
c. Apply power to the Master Boiler.
d. Enter the system setting program navigation following
instructions in Part 10 of this manual.
e. 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. This establishes the unit as the master in a cascaded
system.
f. Change 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.)
g. Exit the installer menu.
NOTE: The temperature set point of the master must match the
follower boiler set point in order for the system to operate properly.
Additional Connected 1000 and 1700 Follower Boilers:
NOTE: READ THE NOTES BELOW BEFORE PROGRAMMING
FOLLOWER BOILERS
•
If one of the follower boilers has an indirect fired water heater
connected directly 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.
•
Maximum amount of boilers in a cascaded system is eight (8),
equal to four (4) double-stacked units.
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 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: DO NOT select number 8.
NOTE: The top boiler in a 1000 or 1700 assembly is factory preset
to 1.
e. Change "CASCADE MODE" Function 23 to COMMON FLUE on all
boilers EXCEPT the Master Boiler. This is the default setting on the
top boiler in a 1000 or 1700 unit.
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.
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.
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:
