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 oor because some gas is
heavier than air and will settle on the oor.
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 re
department.
• Turn o the gas shuto 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 qualied service technician. Force or attempted
repair may result in a re or explosion.
4. Do not use this boiler if any part has been under water.
Immediately call a qualied 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
ecient 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 t your system design and
not require any adjustment at all.
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
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 rst 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.
ENTER MENU CODE
000
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.
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.
