4.3 Initial Start-Up
This section describes the steps involved during the initial start-up procedure for a
Guspro Heat Cleaning Oven after it has been connected to gas, electricity, water and the stack
has been installed.
A summary of factory gas and airflow settings is presented in Table 9.1. These are initial
settings. Final adjustments to these settings may be necessary on-site during the initial start-up.
1. Familiarize the operator with the location of all the controls and the normal operating
sequence based on Section 2.1 and Section 4.4.
2 Before connection the water supply turn the water on and purge the water lines to remove
accumulated dirt and scale in the newly installed piping.
3. Check the gas or fuel supply line for leaks. New fuel supply lines must be pressure
tested. Care should be taken to ensure that the pressure has been released.
Note: Natural gas joints should be checked for leaks with soap and water. Care must
be taken to ensure that air from the pressure test is bled off and not evacuated
through the valve train components. If high-pressure air is accidentally
evacuated through the valve train, it will damage the regulator and pressure
switch diaphragms.
Certified personnel should complete both of these checks!
4. Open the oven doors and remove the cart.
5. Place the firebox tiles on the floor of the process chamber. Install the soaps (small pieces
of firebrick). Starting at the back of the oven place the soap stones in the heat ports as
shown in Figure 4.1. Work your way forward and fill all of the heat ports except the
front one on each side under the cart.
6. Turn on the gas supply and bleed air from the gas supply pipe by loosening the pilot lines
on both burners. The oven doors should be left open to vent any remaining gas from the
purge lines. Tighten the pilot lines.
7. Ensure that all gas valves are open except the oxidizer burner firing valve.
8. Inspect the electrodes for cracks. Check and make sure they are gapped for 1/8".
9. The manual gas flow valve on the process burner should be set at 3.
10. The manual gas flow valve on the oxidizer low fire valve train should be set at 5.
11. The oxidizer chamber airport should be set at 1/2" open.
12. Open the panel door and turn the purge timer down to 30 seconds. Close the panel door.
