Step 7: Verify the Gas Settings

1. Make sure that all the settings are still the same after
you cycle the system several times between high fire
and low fire.
2. When all settings have been completed, mark the
position of the indicator on each butterfly valve to
indicate valve position. This will save time later.
■ Make sure that you close all the pressure taps after
you remove the manometer. Gas that leaks from
the pressure taps can cause fires and explosions.

Step 8: Adjust Low Fire

1. Drive the system to low fire.
2. If a burner goes out, close gas cocks. Go to Step 5
"Ignite the Burners" on page 13, and follow
instructions.
3. Adjust the ratio regulator until the O
10% and 14%.
If the oxygen levels are between 10% and 14%, but
the temperature continues to rise above the
desired level:
4. Reduce low fire air flow by adjusting the zone air
control valve linkage. Recheck oxygen levels at low
and high fire.
5. If necessary, repeat step 3.

Start Procedure

■ If a burner does not light, and the system does not
shut down automatically, then you must close the
main gas cock. An uncontrolled flow of gas can
cause fires and explosions.
■ Do not touch the spark rod or the ignition wire
when the ignition is on. You will get a shock.
Manual Ignition
1. Make sure the gas cock at each burner is closed.
2. Start air blower.
3. Drive the automatic zone air control valve to low fire.

4. Start ignition transformers.
5. Open the gas cock at each burner checking to ensure
that the burner lights.
Automatic Ignition
1. Start the blower.
2. Open all the gas cocks.
3. Start the ignition sequence.
4. Verify that flame is present at each burner.
If a burner does not light and:
• The system does not shut down automatically:
Close the main gas cock manually. Do NOT operate
the system. Go to "Checklist After Installation" on
page 11. Repeat the start procedure.
• The system shuts down automatically:
See "Troubleshooting" on page 17.

Stop Procedure

1. Close the following valves:
• The manual gas cock at the main control valve
• The manual gas cock for each burner or zone
2. Let the burners cool down. Keep the blower on until
the chamber temperature is less than 1000°F (500°C)
and then stop the blower.
NOTICE
■ Keeping the blower on after the burner is off
protects the burner and the other components
from hot gases that flow back through the burner.

Static Air Pressures

When a burner uses preheated combustion air, there are
no air orifices installed. In that case, the static air pressure
is used to set the initial air flow of a burner. From there on
the burner is further adjusted.
