5.0 - PRECAUTIONS
This section briefly discusses basic precautions that should be taken during oven
operation. A comprehensive treatment of maintenance and trouble shooting procedures is
presented in Sections 6-9.
5.1 Loading
1. Plugs or caps should be removed from jackets. Parts that have sealed water or liquids
must not be processed.
Note: Do not process sealed containers or tanks.
2. After the oven has been loaded, the oven doors should be closed and the processing
cycle started. The oven should not be kept loaded with parts and let stand.
Note: Doors should not be opened until the processing cycle is complete.
3. The oven is designed for heat cleaning parts as discussed in Section 1. It should not be
used for reclamation of heavy insulated wire or parts not listed in Table 1.1.
4. The oven should not be overloaded. An overloaded oven is a safety hazard. Oil or other
fluids should be drained from jackets or containers prior to starting the processing cycle.
5.2 Operation
1. The OTS system should be checked prior to processing a load.
2. A log of normally used settings should be maintained.
3. Experience gained through daily usage on different type loads should be logged and used
to determine shop procedures. Faster cycle times can thus be safely determined.
4. The process burner should be initially adjusted to a low fire setting. Opening the burner
manual gas flow valve gradually can increase the load heat up rate.
5. The top tiles should be set together. They may be removed while cleaning the oven.
Note: Do not walk on the tiles.
6. High stack or high wind conditions can cause more heat on one side than the other. This
can be balanced by partially blocking the side ports with firebrick soaps. These can also
be used to partially block the flame ports in the firebox for heat adjustment.
7. Natural gas supply should be maintained at 7'' W.C. with all burners operating at
maximum BTU output. The corresponding setting for Liquefied Propane Gas is 11"
W.C. This is required to ensure that the heat-cleaning oven operates as designed.
