3.3 Main Burner Adjustment

1.Turn unit off.

2.Check to make sure that the pressure equalizer tube is securely connected between the blower and gas pressure regulator.

3.Turn on the unit; about 45 seconds later, the pilot should light. If the pilot fails to light, repeat step 3.2 for pilot adjustment.

4.Turn “Monkey” switch on. The main burner will fire.

5.The blower pressure should increase about 2/10” (0.2”) W.C. equaling the value in tables O-2 or O-3.

6.Make sure that the supply gas manometer reads between 7 – 14” W.C. (dynamic pressure)

7.Check manifold pressure, Location (2); this should read to within ± 0.1” W.C. of the values shown in tables O-2 or O-3.

8.If adjustment is required, turn off the “Monkey” switch.

9.Remove screw cap off the gas pressure regulator, adjust regulator, replace the screw cap, then turn the “Monkey “ switch on. Repeat steps 4 – 9 until the proper gas pressure and/or CO2 are achieved.

10.Allow minimum 5 minutes of run time; then attach flue analyzer, CO2 reading should be within 8.8% and 9.5%.

11.If CO2 is higher than 9.5%, reduce manifold gas pressure.

12.If CO2 is lower than 8.8%, increase the manifold gas pressure.

13.When adjusting blower pressure for excess air, keep all pressure readings especially manifold pressure within ±0.1” of listed values.

3.4 Safety Inspection

•Check all thermostats and high limit settings.

•Attach thermometers to IN/OUT piping and take the temperature measurement, see Table D-1and F-1 for correct flow balance.

•During the following safety checks leave manometers, and analyzer hooked up, check and record.

•If other gas fired equipment in the room and on same gas main check all 4 pressures on ADB with them running.

Remember supply gas should always be 7-14" when boiler is firing.

•Check stats for ON/OFF operation.

•Check Hi Limits for ON/OFF operation.

•While in operation to check, inspect flow switch operation

•Check the low gas pressure switches, low gas pressure switch are factory set at 6" W.C for natural gas an 10" for propane gas.

•High gas pressure switch (optional) at 1" W.C above manifold pressure.

•Insert ignition control lockout tests as safety check.

3.5 Follow-Up

•Safety checks must be recorded as performed.

•Turn unit on.

•After main burner ignition.

Check Manometer for proper reading.

•Cycle unit several times and recheck readings

•Re-analyze with unit running record or print results.

•Turn unit off, remove all Manometers and replace blower switch hose, replace all gas pressure caps and plugs.

•Remove "monkey switch".

•Check for gas leaks one more time.

•Check around unit for debris and remove combustible and flammable products, i.e. paper, gasoline etc.
