M. Initial Operation - Boiler Door and Seal
It is important to ensure that the combustion chamber door
is properly sealed and installed BEFORE attempting to start
the boiler. Failure to do so could result in property damage,
severe personal injury, or death.
NOTE: During initial start-up, the sealing rope may burn
off. During this period a burning smell may come from the
boiler. This is normal and will pass when the sealing rope has
completed burning off.
After the boiler has operated for 12 - 16 hours, the door will
have to be closed again to accommodate any burn-off of the
organic starch sealing rope. Retightening the door after 12 -
16 hours will ensure a proper seal.
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:
ENTER MENU CODE
000
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.
C. Operating Instructions
Before operating the unit, it is important to verify that the gas
line and water lines are connected to the 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
is used.
