BOILER START-UP
WARNING

has accumulated, when unit is full of vapor, or
when combustion chamber is very hot.

Boiler Start-Up Information
• Have a qualified service technician perform the startup
procedures. Refer to boiler Installation, Operation &
Maintenance Manual for full details.
• Instruments are the only reliable method to determine
proper combustion adjustments. An improperly
adjusted burner causes soot and high fuel bills due to
incomplete combustion of fuel oil. This may require
excessive boiler maintenance, service costs, and in
some instances, house cleaning or redecorating.
• ¼” NPT plug is provided in burner swing door to take
draft readings in combustion chamber.
• Chimney vent only, does not apply to direct vent
boilers. ¼” diameter hole is required in the flue pipe
between boiler and barometric damper to take draft,
CO
2
, smoke and temperature readings.
• Adjust air shutter on oil burner to obtain “trace”
of smoke. Measure CO
2
at this point. Increase air
adjustment to lower CO
2
by one-half (1/2) percent to
one (1) percent.
• Verify zero (0) smoke and correct draft is obtained for
installed unit. Reference boiler Installation, Operation
& Maintenance Manual for correct draft settings. If
proper draft can not be maintained, changes and/or
modifications may be required in venting or chimney.
Restarting after Ignition Failure (Lockout
)
Riello Oil Burners:
• Lockout is indicated by red reset button illuminating on
oil burner primary control. Press and release red reset
button ONCE to reset the control. If there is call for
heat burner will start.
• Burner goes into lockout second time, or fails to
operate after reset button is pushed, contact qualified
service technician to service boiler.
