DJUSTMENT
In this chapter,you will find instructions on how to adjust,start,and stop the burner system. Become familiar with burnercontrol methods before attempting to make adjustments..
Danger:
d
The Winnoxburners,described herein,aredesigned to mix fuel with air and burn theresulting mixture.All fuel burning devices arecapable of producing fires and explosions ifimproperly applied,installed,adjusted,controlled,or maintained.
Do not bypass any safety feature;fire or explosioncould result.
Never try to light a burner if it shows signs ofdamage or malfunction.
Adjustment steps:
1.
Reset the system
2.
Set low fire air
3.
Ignite the burner

.Set low firegas
5
.Set high firegas
6.
Verify settings
Step 1:Reset the system
Reset procedure:
1.
Set the low gas pressureswitch to 20% below the Maingas inlet pressure range as specified in the appropriatedata sheet.
2
.Set the high gas pressureswitch to 20% above the Main
gas inlet pressure range as specified in the appropriatedata sheet.
3.
Close all the burner gas valves,manual and automatic.
4.
Try to ignite the burner;be sure the flame monitoringsystem indicates a flame failure.

5.
Activate the pressureswitches and other limit interlocks.Be sure the switches fail as intended in the event of apower failure.
Danger
d
If simulated limits or simulated flame failuresdonot shut down the fuel system within therequired failureresponse time,immediatelycorrect the problem beforeproceeding.
6.
If the burner is firing into a duct or chamber with acirculating fan,start the fan to produce afull process airflow past the burner.
7.
Adjust main gas inlet pressure to the ratio regulatorwithin the range specified in the appropriate data sheet.
Warning:
w
Gas inlet pressures must stay within the specifiedrange.Pressure above the specified range can
damage the ratio regulator.
Warning:
w
Pressurebelow the specified range can impair theability of the ratio regulator to control the gasflow.
Operating the system outside the specified rangecan cause excess fuel consumption and thepossible accumulation of unburned fuel in thechamber.
In extreme cases,this accumulation of unburnedfuel may cause fires or explosions.

Low fire air adjustment procedure:
1.
Start combustion air blower.
2.
Drive control motor to lowfire position.
3.
Measure air differential pressure between tap (C ) andcombustion chamber.
Note:
n
The pressure tap is in the open position when the screw insidethe tap is unscrewed approximately 1/2 turn.Do not removescrew.Be sure to tighten pressure tap screwclockwise to theclosed position after pressure measurements have been taken.
4.
Set low fire air.
a.
Loosen the set screw1on burner side of coupling 2.
Note:
n
There is a slot in the end of the BV shaft that is parallel tothe air damper.This slot is used for visual indication of the BVposition.The BV is closed when the shaft slot is perpendicularto the direction of air flow through the BV.
b.Rotate air BV shaft to fully closed position.(Holes
in BV damper will supply low fire air.)
Note
n
When firing into a positive chamber pressure,rotate the airBVfrom closed position in the direction of actuator travel toobtain a minimum 0.3w.c.(0,8 mbar)air differentialpressure.

High fireair adjustment is not required if burner is firing intoa neutral pressurechamber and a 90° travel control motor isused.
It may be necessary to limit control motor stroke to less than90° if firing into a large positive or negative chamber.
Contact your Eclipse Combustion representative for furtherinformation.
5.
Verify high fire air
a.
Drive control motor to high fire,full open.
b.
Compare the high fire air differential pressurebetween tap (C) and the combustion chamber to theappropriate data sheet chart Air ∆P vs.Input.Ifhigh fire air is insufficient,refer to Section 5,Troubleshooting and Maintenance,in this document.

These are guidelines only.The customer should make thefinal determination on maintenance intervals and tasks tobe performed while considering the working environment.
Inspect the flame sensing devices for good condition andcleanliness.
Check for proper air/gas pressures (Refer to the WinnoxData Sheets, Series 111).
Test all the system alarms for proper response signals.Check and clean igniter electrodes.Check the air control valvefor smooth,trouble free
operation and adjustment.Check for the proper operation of ventilating equipment.Test the interlock sequence on all safety equipment.
Manuallyforce each interlock to intentionally fail while atthe same time noting if related equipment closes or stopsas specified bythe manufacturer.Test the flame safeguardby manually shutting off the gas to the burner.
Test the manual gas shut off cocks for proper operation.Clean and/or replace the combustion air blower filter.Inspect and clean the combustion air blower rotor.

1.
Leak test the safety shut-off valvesfor tightness of closure.
2.
Test the pressureswitch settings bychecking the switchmovements against pressure settings and comparing thesewith the actual impulse pressure.
3.
Visually check igniter cable and connectors.
4.
Inspect impulse piping for leaks.
5.
Be sure the following components are not damaged ordistorted:
the burner nozzle.
the igniter.
the flame sensors.
the combustion tube or block.

The nozzle can be inspected without removing the burnerfrom the chamber wall or entering the chamber.Perform thefollowing:
a.
Shut the burner off and manually close the main gas
shut off cocks.
b.
Allow the chamber temperature to cool down to 250°F
(121°C).
c.
Disconnect the gas piping at a union or the gas inlet
flange 1provided on the burner.
d.
Removethe four bolts 2.
Caution:
c
Do not attempt to removerearcover byremoving the innercircle bolts5.Internal burner parts will be damaged.
e.
Removethe rear cover 3from the burner housing 4.
f.
Toreassemble,follow this sequence in the reverse
order.
Note:
n
The combustor can be inspected only byremoving the burnerfrom the chamber wall or entering the chamber.

Gas cocks are used tomanually shut off the gassupply on both sides of themain gas shut-off valve train.
Solenoid valves are used toautomatically shut off the gassupply on a bypass gas systemor on small capacity burners.
Apressureregulator reducesgas pressure to a stable,usablepressure.
A ratio regulator is used to controlthe air/gas ratio.The ratioregulator is a sealed unit thatadjusts the gas flowin ratio withthe air flow.To do this,it measuresthe air pressure with a pressuresensing line,the impulse line.Thisimpulse line is connected betweenthe top of the ratio regulator andthe burner body.
