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.
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.
