TABLE 3c: RIELLO BURNER CONFIGURATION AND SETUP DATA

XII Service and Maintenance

The following procedure should be performed on an annual basis:

1) Turn off electrical power and oil supply to the boiler.

2) Clean the boiler as follows:

a) Remove vent connector and piping.

b) Remove barometric draft regulator.

c) Remove top jacket panel to gain access to boiler ue collector.

d) Unscrew four wing nuts and remove canopy retaining carriage bolts, lift off the canopy and ceramic ber sealing

e) Unplug the burner, disconnect the oil lines (if the pump is hard piped), and remove the two 5/16” bolts securing the

strips.

burner door. Open the burner swing door.

25

f) Thoroughly brush boiler ueways from the top and diagonally between casting pin rows. Be careful when brushing the

rear passage not to damage the rear target wall insulation.

g) Vacuum soot and debris from combustion chamber.

h) Check condition of rear target wall insulation, combustion chamber liner, and burner door insulation; replace if required.

i) Check burner head for signs of deterioration. Clean the head of any deposits.

j) Close burner door, reinstall 5/16” bolts, reconnect fuel oil and electrical lines.

k) Installation of boiler canopy, jacket top panel barometric draft regulator and breeching piping is done in reverse order
of removal. Make sure canopy is sealed tight to the casting; replace ceramic ber sealing strips as needed. All vent piping
joints must be ue gas leak free and secured with sheet metal screws.

IMPORTANT

• CLEAN THE BOILER EVEN IF THERE ARE NO SIGNIFICANT SOOT DEPOSITS. FAILURE TO
REMOVE ALL SULFUR AND ASH DEPOSITS ANNUALLY CAN CAUSE SEVERE CORROSION
DAMAGE.

• WHEN CLEANING THE REAR FLUE PASSAGE, BE CAREFUL NOT TO PUSH THE BRUSH TOO FAR
BEYOND THE BOTTOM OF THE PINS. DOING SO MAY DAMAGE THE TARGET WALL.

3) Inspect the vent system:

a) Make sure that the vent system is free of obstructions and soot.

b) Make sure that all vent system supports are intact.

c) Inspect joints for signs of condensate or ue gas leakage.

d) Inspect venting components for corrosion or other deterioration. Replace any defective vent system components.

4) Service the oil burner:

a) Replace oil nozzle with identical make and model (see Table 3).

b) Inspect the electrodes. Replace if they are deteriorated. Make sure that the electrode position is set according to the
burner manufacturer’s instructions.

c) Remove and clean fuel pump strainer.

d) Remove any accumulations of dust, hair, etc. from the air shutter, blower wheel, and other air handling parts of the

burner.

5) Replace the fuel oil line lter element and gaskets.

6) Inspect all oil piping and ttings for kinks and leaks. Repair any found.

7) Inspect the hydronic piping, tankless coil gasket, and boiler plugs for water leaks. Repair any leaks found immediately.

8) Verify operation of relief valve by manually lifting lever; replace relief valve immediately if valve fails to relieve pressure.

9) Open fuel line shut-off valve(s) and restore electrical power to the boiler.

10) Fire the boiler and check it out using the procedure outlined in “Start-up and Checkout” . This must include checking the
burner adjustments using instruments. Check for proper operation of all controls.

WARNING

WATER LEAKS CAN CAUSE SEVERE CORROSION DAMAGE TO THE BOILER OR

OTHER SYSTEM COMPONENTS. REPAIR ANY LEAKS FOUND IMMEDIATELY.
