BEARING INSTALLATION AND MAINTENANCE

NOTE: To prevent premature failure – please ensure greasing instructions below are applied. As well,

tighten bearing set screws, collars, and wheel lugs every four to six months.

ENGINEERING – BALL & ROLLER BEARINGS LUBRICATION

For bearings that are equipped with a hydraulic grease fitting threaded into the housing for ease of lubrication, the proper amount of lubricant in the bearing is important. Both excessive and inadequate lubrication may cause failure.

The bearings should be re-lubricated while they are rotating (if it is safe to do so); the grease should be pumped in slowly until a slight bead forms around the seals. The bead in addition to acting as an indicator of adequate relubrication provides additional protection against the entry of foreign matter and helps flush out contaminates in the bearing.

By the time the slight bead is formed, it will be noticed that the bearing temperature will rise. It is not uncommon for the temperature to rise as much as 30 degrees Fahrenheit after re-lubrication. If necessary to re-lubricate while the bearing is idle, refer to the recommended re-lubrication grease chart tables on the following page for various sizes of the bearings.

Lubricant-Standard Bearings:

All bearing units are pre-lubricated at the factory with a lithium soap grease which is compatible with multi-purpose grease readily available from local suppliers. The lubricant selected for factory lubrication uses a highly refined mineral oil with a high viscosity index, thickened with lithium soap to conform to NLGI grade 2 consistency. A suitable additive package is added to protect the highly polished rolling contact surfaces from corrosion and oxidation of the lubricant. The lubricant is satisfactory for an operating temperature range of –30 F to +250 F.

Select standard industrial grade greases that conform to the following specification for optimum bearing performance:

General Duty Ball & Roller;

58-75 SUS @ 210 F

450-750 SUS @ 100 F

Premium Duty Ball & Roller;

68-75 SUS @ 210 F

600-750 SUS @ 100 F

Heavy Duty Roller Bearing;

82 SUS @ 210 F

886 SUS @ 100 F

NOTE: For heavy loaded roller bearing applications, grease with EP additives are often recommended for optimum performance.

Frequency of re-lubrication depends upon operating conditions. The bearing operating temperature is the best index for determining a re-lubrication schedule. The following chart gives the frequency of re-lubrication based upon continuous operation for various operating temperatures and can be used as a satisfactory guide for determining when bearings should be re-lubricated.

TENSIONING V-BELT DRIVES

1. Ideal tension is the lowest tension at which the belt will not slip under peak load conditions.

2. Check tension frequently during the first 24-48 hours of operation.

3. Over-tensioning shortens the belt and bearing life.

4. Keep belts free from foreign material that may cause slip.

5. Make V-drive inspection on a periodic basis. Tension when slipping. Never apply belt dressing as this will damage the belt and cause early failure.

Check and tighten belt tension. The following procedure is recommended for tightening belts: a) Measure span “X” shown in Figure A. b) At the center of span length “X”, apply a force perpendicular to the span and large enough to deflect belt

1/64” for each inch of span length. Example- the required deflection for a 40” span would be 40/64” or

5/8”. c) Compare the force applied with the values given in Table III. If force is between the minimum and maximum range shown, the drive tension should be satisfactory. A force below the minimum value indicates an under tightened belt and force that exceeds the maximum value indicates an over tightened belt.

4. Check the piping for leaks. A quick way to do this is to turn off main shut-off valve “A” and pilot valve “B”, then turn on the gas pressure to the gas supply line and observe the meter test dial. There should be no movement of the dial hand for at least five minutes on a half foot dial (proportionally longer on larger dials).

All other gas appliances must, of course, be completely shut off during this test. If a leak is detected it should be located with a soap suds test and corrected. If air or inert gas (do not use oxygen) under pressure is used for leak detection, do not subject the main and pilot valves or regulators to pressure readings exceeding ½ PSI

(disconnect piping to prevent damage during high pressure leak testing).

5. Purge the gas supply line up to the main and pilot manual valves. Do not purge into the combustion chamber.

6. Make sure that the main and pilot manual gas valves are closed and that the burner line switch is off.

7. The pilot gas pressure regulator is set for 3 ½ ” W.C. outlet pressure which is suitable for natural gas and average draft conditions. If propane gas is to be used, adjust the regulator to its minimum outlet pressure setting.

8. Firmly push in the flame safeguard manual reset button “C” and the Model F400 motor manual overload reset.

9. Check that the blower motor rotates freely.

10. Turn line switch on momentarily and check for proper blower wheel rotation.

11. Open pilot manual valve “B”.

12. Trial for pilot ignition. Turn switch to winter operation. If power vented, burner will be powered when air switch contacts close. Flame safeguard is powered, motor relay 3K pulls in. As motor reaches operating speed, the blower interlock switch “makes” to initiate a 30 second prepurge period. After prepurge, the load relay 1K pulls in to energize the pilot solenoid and ignition transformer and the pilot should light.

13. If the pilot fails to light during the 15 second trial, it is probably due to air in the pilot line. Wait one minute and push flame safeguard reset button to restart, (400 motor will continue to run during the safety lockout. F400 motor will stop approximately 15 seconds after solenoid valve closes).

14. Observe the pilot flame. If it is weak, screw in the pilot regulator adjustment. If it is excessively rich and large or floating from the pilot tip, back off the regulator adjustment. Set the pilot to a stable blue flame which burns firmly within the pilot tip. Check flame current with a DC volt meter. It should show a steady 15-17 volts

(Fireye) or 3-5 VDC (Honeywell). Operate air shutter throughout range to check pilot stability. Adjust pilot regulator slowly to obtain highest reading possible, try several relights.

15. Set the shutter to match the intended input, i.e. full open for maximum, closed for minimum or partially open for mid-range.

16. Slowly open main manual valve until the main flame ignites. Continue to open valve, adjusting air shutter if necessary, if the manual valve is fully opened before input is reached, screw in regulator adjustment. Set regulator to desired manifold pressure, marked on the rating plate.

NOTE: Do not screw the adjusting nut in past the point where no further increase in manifold pressure is noted.

If the specified pressure cannot be reached, check for proper inlet pressure at the inlet of the main manual valve with the burner running.

17. Readjust the main air shutter to provide a quiet soft flame-blue at the burner nozzle with well defined orange tips for natural gas or with well defined yellow tips for propane.

18. The primary air adjustment which affects the flame length, has been set wide open for average conditions.

Decrease the primary air if a longer, softer flame is desired.

19. Cycle the burner on and off several times to check its operation.

20. Check the operation of the limit and operating controls.

21. Check the flue gas temperature ahead of the diverter. It should be above 300

°F . Excessive flue temperatures will result in low efficiencies. Low flue temperatures may cause excessive condensation. Reset gas input if necessary to adjust stack temperature, (on/off operation only).

13

22. Make the final setting of the air shutter by checking the flue gases with an “Orsat” or other similar combustion testing instrument. There should be no carbon monoxide and the carbon dioxide content should be within limits prescribed by the local gas company. Make sure that the main air shutter is locked securely in place.

23. Recheck pilot to make sure that its operation has not deteriorated because of main shutter adjustment. If necessary, readjust pressure regulator.

24. Modulation operation: see wiring diagram and modulating instruction sheets supplied with this unit for correct set up.

25. If linkage between Butterfly valve and Burner (gravity unit only) and venter fan if power vented needs to be adjusted from factory setting, (see below).

GIDM LINKAGE SET-UP WITH POWER VENTS

1. Install a manometer on suction at test port in pop-up door.

a) Ensure there is a negative pressure at that point on low fire through to high fire.

- .50 to - 75” W.C. low fire and -.01 to -.10 on high fire.

2. To increase exhaust move drive rod toward damper pin (decrease the distance between drive rod and center pin).

3. To increase combustion air move drive rod towards center pin (decrease the distance between drive rod and center pin).

4. To ensure a negative pressure throughout full modulation range, you may have to speed up exhaust and or burner damper to match gas flow to the burner.

Move drive rod closer to the drive pin on the butterfly valve, (this will reduce the movement of the burner damper).

5. Adjust low and high fire on the stop screws on the butterfly valve.

NOTE: The motor is allowed to over run with the spring linkage set the travel on the Penn Johnson motor to ensure it does not go to far or damage to the motor could occur.

GP TYPE C FORCED DRAFT BURNER C-6.2 TO C-12.9

INITIAL START UP

1. Make sure burner power switch is off and manual main and pilot valves are closed.

2. Make proper settings on limit controls.

3. Have on hand CO and CO

2

tester, stock thermometer, 0” to 30”W.C. gas pressure gauge, u- tube manometer and

D.C. volt meter.

4. Turn on burner power switch momentarily to check blower rotation.

5. Check gas tightness of main and pilot safety shut off valves (if used) by connecting a pressure gauge to the

pressure tap located between the safety shut-off valve and the test firing valve. When the test firing valves are

closed and the manual shut-off valves are opened, no pressure rise should show on the pressure gauge.

6. The air damper has been factory set approximately during test firing if need to adjust see linkage set up sheet provided with unit. Turn on the burner switch, while the main and pilot gas firing valves are closed. After the prepurge the ignition transformer and solenoid valves will be energized. Observe the ignition spark for proper location and firmness. After the trial for ignition time, the ignition transformer and solenoid valve are deenergized and the burner will lock out.

7. Open the pilot test firing valve and turn on the burner switch, while the manual main shut-off valve stays closed.

After the prepurge, the ignition transformer and the pilot solenoid valve are energized. Observe the pilot flame and if necessary, adjust the pilot pressure regulator to obtain a stable flame with the highest steady flame signal.

For flame signal readings, see attached flame safeguard manual. With the main manual shut-off valve still closed, the flame safeguard will lock out after approximately 10 seconds, only with high/low and modulating burners which use an interrupted pilot. Repeat the ignition cycle a few times to ensure a fast ignition and stable pilot flame.

8. Open the main manual shut-off valve and set the high/low limit switch and the modulating controller so that after establishing a main flame, the burner will travel to high fire. Start the burner. In high fire, check the manifold pressure with the required pressure for the firing rate, (see suggested inspection list) and if necessary, adjust pressure regulator. Readjust the air damper if fire looks to lean or too rich.

9. Take a gas meter reading and readjust manifold gas pressure if necessary. Take a CO

2

CO

2

should be between 8-1/2 and 9-1/2 % and O of .04%. Readjust air damper accordingly.

2

or O

2

and a CO reading.

should not be more than 5%, both with a maximum CO reading

10. With high/low and modulating burners, mark the high air damper position and set the high/low limit control or modulating control so that the burner travels to low position. Visually adjust the input adjuster on the main gas shut-off valve actuator if low fire is too rich or too lean. Take gas meter reading and readjust the input adjuster according to the required low fire input, but not less than indicated in the specifications table. In order to keep the high fire setting unchanged when adjusting the low fire air damper position, drive the burner to high fire, change the positioning of the linkage as indicated in “Low Fire Adjustment”, drive the burner back to low fire and check the CO

2

or O

2

readings. Repeat this procedure until a satisfactory setting is obtained.

11. Make sure all linkage connections are tight and check the readings in high and low fire again.

11a. The motor is allowed to over run with the spring linkage. Set the travel on the Johnson motor to ensure it does not go too far, or damage to the motor could occur.

12. Reset controller and limits to their desired settings.

WARNING

DO NOT ADJUST FLAME VISIBLY. INSTRUMENTS ARE THE ONLY SAFE AND

RELIABLE MEANS TO DETERMINE THE PROPER ADJUSTMENTS.

16

BURNER SAFETY CHECK

1. Start and stop burner several times to ensure proper operation.

2. Check operation of combustion safeguard control by simulating a flame failure, making certain the burner locks out on safety within the proper time.

3. Check operation of the air flow switch, making certain fuel valve closes when the air flow diaphragm switch opens.

4. Bypass discharge controller and check to ensure high limit will shut down burner on temperature increase. If changed reset as per factory setting.

5. Reset operating control to desired temperature. Permit burner to run until it is shut off by the operating control.

Adjust operating control, if necessary, until it causes burner to stop and start within desired range.

6. With the burner running, check hi and low gas pressure switch if on manifold. The burner should shut off immediately.

7. Conduct minimum, pilot turn down test, reduce gas pressure to pilot with manual shut off cock to the point pilot flame is extinguished or fails to prove. Increase gas flow slightly. Main flame must be ignited with this pilot flame.

8. The following readings should be taken and record after final adjustments have been made.

a) Burner input (CFH gas).

b) Percent CO

2

or O

2

.

c) CO indication.

d) Stack temperature.

e) Firebox pressure.

f) Fuel pressure (in W.C.-gas) (main and pilot).

g) Voltage to burner.

9. Give instruction to owner (operator).

WARNING: SHOULD OVERHEATING OCCUR

1. Shut off the manual gas control (s) to the burner.

2. Do not shut off the control switch to the pump or blower.
