Installation, Operation and Care of

MODEL GPO72 GAS PIZZA OVEN

PLEASE KEEP THIS MANUAL FOR FUTURE USE

GENERAL

Vulcan pizza ovens are produced with quality workmanship and material. Proper installation, usage
and maintenance of your pizza oven will result in many years of satisfactory performance.

It is suggested that you thoroughly read this entire manual and carefully follow all of the instructions
provided.

Standard features include an aluminized interior, stainless steel front, sides, top, flue deflector, and 27"
legs for a single oven or 17" legs for a stacked oven (Model GPO722). Optional accessories available
include a Pyrorock core plate hearth, down draft diverter for direct vent connection, porcelain enamel
interior, and 115 volt cord and plug to provide electrical power to the thermostat.

Each single oven is equipped with two 50,000 BTU/hr. burners, or a total of 100,000 BTU/hr. total input
per oven.

INSTALLATION

Before installing, verify that the electrical service (if applicable) and type of gas supply (natural or
propane) agree with the specifications on the rating plate located behind the lower front panel on the
left side. If the supply and equipment requirements do not agree, do not proceed with the installation.
Contact your dealer or Vulcan Company immediately.

UNPACKING

This pizza oven was inspected before leaving the factory. The transportation company assumes full
responsibility for safe delivery upon acceptance of the shipment. Immediately after unpacking, check
for possible shipping damage. If the pizza oven is found to be damaged, save the packaging material
and contact the carrier within 15 days of delivery.

Carefully unpack the pizza oven and place it in a work-accessible area as near to its final installed
position as possible.

LOCATION

The equipment area must be kept free and clear of combustible substances.

When installed, minimum clearance from combustible and non-combustible construction must be 0"
at the sides and 6" at the rear. The oven is suitable for installation on combustible floors.

The installation location must allow adequate clearances for servicing and proper operation. A
minimum front clearance of 48" is required.

Do not obstruct the flow of combustion and ventilation air. Adequate clearance for air openings into
the combustion chamber must be provided. Make sure there is an adequate supply of air in the room
to replace air taken out by the ventilating system.

Do not permit fans to blow directly at the pizza oven. Wherever possible, avoid open windows next to
the pizza oven. Avoid wall-type fans which create air cross currents within the room.
