Initial Checks

Before operating your unit, make sure the side of your convection oven, where the controls are located, are at least two inches from other cooking or heat producing equipment. This space is needed to ensure the oven's mechanical components don't overheat and remain cool.

Burn Off Procedure

Before initial use, the convection oven must undergo a "burn off" procedure to remove any contaminants from heating the chamber. Here are the quick steps to conducting a burn off procedure for the Vulcan VC4 Convection Oven.

Step 1: Wipe down the inside of the oven:

Use a damp cloth to wipe the inside of the oven and oven racks.

Step 2: Close the oven Doors:

Close the oven doors. Turn the oven on: Switch the master switch to the "ON" position.

Step 3: Conduct Burn Off Procedure:

Turn the thermostat to 300 degrees Fahrenheit and allow the oven to cycle for 90 minutes or until no smoke or odor is detected. After that period, turn the master switch to "OFF".

Vulcan VC4 Cleaning & Care

Let's go over some of the best and recommended cleaning procedures for your Vulcan VC4 convection oven. Be sure to always allow the unit to cool before you begin cleaning. At the end of every day, turn the oven thermostat off, and switch the master switch to cool. Leave the oven doors open, while the fan is on, to cool the oven. When the oven has cooled enough, switch the master switch off to begin cleaning and follow lockout/tag-out procedures.

Cleaning a Vulcan Convection Oven

It is recommended to clean the convection oven at the end of each day. Follow these simple steps to find out how to clean a Vulcan Convection Oven:

  1. Do not spray the oven interior, or exterior, with a hose.
  2. Do not use highly chlorinated or alkaline detergents to clean the interior of the oven, as these types of solutions can lead to early degradation of the components.
  3. Never use steel scrapers, this can cause damage to the surfaces and components of the oven.

For daily oven cleaning, clean the interior of the oven with warm water and soap or detergent. Rinse thoroughly and wipe dry with a soft clean cloth. While cleaning, don't forget to clean the oven's interior back panel and periodically check for debris around the interior air rotor to remove any small bits of aluminum foil from the fan area. Exterior surfaces may be cleaned using a damp cloth with mild detergent and a warm water solution. When scraping off heavy deposits of grease or oil from the oven use wood, plastic, rubber tools, or anything non-metallic. One of the easiest ways to keep your oven clean is to always use a drip pan.

When should you not use a convection oven?

We suggest not using a convection oven when cooking delicate or specialty foods such as cakes, custards, quick bread, or souflés. These dishes might benefit from the steady heat however the movement of the air from the fan and exhaust system can cause them to cook unevenly or to rise less impressively.

How to Fix Cooking Issues?

UNEVEN BROWING / OVERCOOKED EDGES: A convection oven relies heavily on proper airflow. If you are experiencing uneven browning or overcooked edges, adjust the heat temperature to a lower setting. You can also reduce the number of racks to better the airflow inside the heating chamber. SHRINKING FOOD: Shrinking food while using a convection oven can be solved by lowering the roasting temperature or placing a 12-x-20-x 1-inch pan of water at the bottom. SPILLING AND OVERFLOW ITEMS: Check and adjust the racks inside the oven to prevent items from spilling or flowing over the edge of a pan. Adjust them accordingly if needed. Your racks should be level across and 1/8 inch lower at the front. Be sure to check your pans if they are damaged or warped.

Convection oven excessive or low heat?

Experiencing low, excessive, or sometimes no heat at all can be frustrating when using your commercial convection oven. Luckily this problem can be solved fairly easily and is commonly caused by one of the following. DEFECTIVE TEMPERATURE CONTROL OR PROBE / OPEN HIGH-LIMIT SWITCH OR THERMOSTAT. Other issues can be caused if you have a gas model such as INADEQUATE GAS PRESSURE OR PLUGGED GAS ORIFICE.
