1.3 Burners
Gas burners are equipped with approved ignition and flame safety systems. The burners
may be used with Liquefied Propane Gas (LPG) by a modification to the orifice. Fuel oil fired
ovens are available upon request.
1.4 Materials of Construction
All Guspro ovens are fabricated with hot rolled 7-gauge steel floors and 12-gauge steel
wall and roof backed by a framework of 3" channel, tube and flat iron. All steel work is finished
with two coats of 400
o
F heat resistant paint on the outside, while the insides of the steel walls
are coated with chemical resistant Mastic.
The inside of oven walls and doors are insulated with three layers of insulation. The
innermost layer consists of 2" mineral fiber rock board, which is rated at 1200
o
F. The next two
layers are made of 1/2" ceramic fiber board, which is rated at 2300
o
F.
The wall insulation is anchored to the steel skin with stainless steel pins and clips.
The process chamber doors are equipped with a high temperature ceramic tadpole gasket,
hinges and cam type safety locking latches.
The floors are poured with 3" thick castable refractory. Cart tracks are embedded in the
refractory floor. Removable external cart track extensions are included.
Note: The cart track extensions may be left in place at all times. They do not have to be
removed to close the oven door.
The self-supporting stack is fully lined with a 2300
o
F castable refractory. It is designed
to provide natural draft operation, and does not require either an exhaust blower or induced draft
fan.
1.5 Instrumentation and Control
A microprocessor - controlled operating system coordinates the functions of the process
burner, the oxidizer, and the Over Temperature Suppression (OTS) System during a heat
cleaning cycle. After the heat cleaning cycle, the system shuts down to cool.
All oven models have an OTS system included. The ovens come with a separate process
chamber excess temperature backup sensor. This will activate the OTS system by water mist
