A. PLACING BOILER IN OPERATION
1. Start up the Burner/Boiler per the Burner Manual
and the instructions in this manual on starting the
boiler.
2. Prove the correct operation of all controls on the
boiler and burner as outlined below.
3. Check the operation of the ignition and flame
proving controls as described in the Burner Manual.
4. Test the limit and operating controls to assure they
are operating correctly.
5. Inspect and test all low water cutoffs.
6. Test the safety relief valve(s) using the procedure
given by the valve manufacturer on the valve tag.
7. Visually inspect the burner and pilot flames (if
applicable).
B. TO SHUT DOWN THE BOILER
1. Turn off Burner.
2. Open main line power disconnect switch to
boiler/burner.
3. Close fuel shut-off valves.
4. To take boiler out of service if the boiler and system
are not to be used when temperatures are below
freezing:
a) Drain the boiler and system completely and shut
off make-up water supply.
b) Open main line power disconnect switch to
boiler/burner. Remove the fuses or secure the
switch so that the power cannot be turned on
accidentally.
c) Be certain that the boiler and system are refilled
before returning to service. Follow the
Instructions in this manual and the Lighting
Instructions to operate.
d) The system may be filled with a 50% inhibited
propylene glycol solution for protection down to
-35°F. Use only antifreeze solutions specifically
designed for hydronic use.
C. MAINTENANCE – ANNUAL
1. Before the start of each heating season, inspect
and make all necessary adjustments to insure proper
boiler and burner operation. Use the maintenance
and inspection procedures following.
2. Inspect the Venting System
a) Check the chimney or vent to make sure it is
clean and free from cracks or potential leaks.
b) All joints must be tight and sealed.
c) The vent connector must extend into, but not
beyond the inside edge of the chimney or vent.
3. Inspect the Boiler Area
a) The boiler area must be clean and free from
combustible materials, gasoline or any other
flammable liquids or vapors.
b) The combustion air openings and the area
around the boiler must be unobstructed.
4. Inspect boiler flueways and burner for cleanliness. If
cleaning is required, use the following procedure.
a) Turn off all electrical power to the boiler.
b) Remove Jacket Middle Front Panel and Jacket
Top Panels. Remove Front Cleanout Plate and
Cleanout Cover Plates on each flueway. On LCE
boilers, remove the top flue outlet plate and vent
piping as necessary to access the top of the
sections.
c) Brush the boiler tube spaces both horizontally
(through cleanout openings on ends) and
vertically (from top of boiler through cleanout
openings at flueways).
MAINTENANCE
Do not store or allow combustible or flammable
materials near the boiler. Substantial fire or explosion
hazard could result, causing risk of personal injury,
death or property damage.
Do not use this boiler if any part of it has been under
water. Immediately call a qualified service technician
to inspect the boiler. Any part of the control system,
any gas control or any burner or gas component
which has been under water must be replaced.
Should overheating occur or the fuel supply fail to
shut off: Shut off the fuel supply at a location
external to the boiler. Do not turn off or disconnect
the electrical supply to the pump. Immediately call a
qualified service technician to inspect the boiler for
damage and defective components.
WARNING
Before servicing the boiler:
• Turn off all electrical power to the boiler.
• Close the Gas Service Valve and Oil Shut-Off Valve.
• Allow the boiler to cool if it has been operating.
• Label all wires prior to disconnection when
servicing controls. Wiring errors can cause
improper and dangerous operation. Verify proper
operation after servicing.
