Special  Instructions.

1.  Review Manufacturers Instructions.


Items to Check & Initial Completion:

1. ___ Test and inspect burner (with or without firing) at rated pressure for
       leaks.
2. ___ Timed trial for ignition for pilots and burners should be in accordance
       with the instructions in the programmer timer.
3. ___ Check operation of automatic controls and combustion flame safeguards for
       normal operation. There should be no presence of oil discharge, ignition
       or flame.
4. ___ Check pre-ignition purging capability of burner, combustion chamber,
       boiler passes, and breaching. Stack dampers should be fully open during
       purge and light off period.
5. ___ Check delivery of fuel in relation to its response to the ignition system.
       Examine electrodes for carbon buildup, discoloration, distortion, and
       burning of parts, clean and adjust as necessary for proper operation.
6. ___ Check ignition transformer to supply dependable arc, adjust and regulate
       as required for clearance and air gap.
7. ___ Clean and adjust draft regulator and air shutter on a natural draft burner
       to ensure excess air quantities are minimum for complete combustion.  Test
       with flue gas analyzer.
8. ___ On mechanical draft burners clean and check power driven fan blower.
9. ___ Check out forced draft fan, clean fan and fan housing, check bearings,
       pulleys and or couplings and adjust belt tension if required replace worn
       belts and lubricate pivot points on linkages as necessary.
10.___ Check and clean filters, water separators, primary and secondary
       strainers.
11.___ Clean, check operation, and adjust controls and safeties.
12.___ Burners designed to change firing rates automatically should be checked
       for adequate proportioning changes in fuel and air rates.
13.___ Check oil level sight glass to see that burner maintains proper oil level
       (within 1/3") at rated output.
14.___ Check to ensure that power cannot feed back and energize ignition devices
       or feed valves after a control shuts off burner.
15.___ Clean or replace nozzles or cups, and check for tight shutoff  of fuel.
16.___ Check stacks for smoke or haze and adjust burner accordingly.
17.    Take flue gas readings to determine the boiler efficiency.  Use the
manufacturer's instructions if available  If they are not, use the attached table
as a guide for the performance criteria.  If efficiency is low, check baffling
and passes for short circuiting, and boiler for air infiltration.  Adjust dampers
and controls to optimize efficiency.  Tests should be run at the following load
points.

    a.___ 100%, 70%, and 40% of rated full load for boilers having metering
          controls or modulation capacity at these load points.
    b.___ At the high and low fire rates on boilers equipped with OFF/LOW
          FIRE/HIGH FIRE control.
    c.___ At the single firing load point on boilers equipped with OFF/ON
          controls only.

Performance Criteria for Oil Burners

1. ___ Combustibles should be zero or negligible percent in flue gas.
2. ___ Output (steam flow or water flow) where meters are available should
       correspond to combustion level not less than 100% of rated capacity at
       rated load.
3. ___ Boiler section outlet flue gas temperature is not more than 30oF (17oC)
       higher than rated.  When expected gas temperature is not known, the
       manufacturer should be contacted for typical conditions for the type
       boiler being tested.
4. ___ Boiler section outlet flue gas temperature should not be more than 150oF
       to 180oF (84oC to 100oC) higher than the corresponding saturated steam
       temperature for water tube boilers and 100oF to 125oF (56oC to 70oC) for
       firetube boilers.
5. ___ Excess air should be within 5 percent of manufacturer's expected
       performance level.
6. ___ Feedwater temperature, burner atomizing pressure, fuel oil viscosity at
       the burner, draft loss and combustion appearance should be in accordance
       with manufacturer's data or be close to industry standards.
