IMPORTANT SAFETY WARNING:
Improper installation and use of the pizza oven is dangerous. Extreme care and caution
should be exercised as the pizza oven can produce intense heat and the risk of accidents
or potential injuries exists. In addition to the instructions, follow these safety guidelines
to reduce the risk of fire, burns and other injuries:
• Installation of the oven should be done by a qualified gas technician. Do not
attempt to repair or replace any parts of the pizza oven yourself. Ask the technician
to show you how to shut the gas off and what to do if you smell gas.
• If you smell gas, it is likely the connection is not sealed correctly, you have a leak
and even if the oven appears to be operating properly, you need to turn off the
pizza oven and shut off the gas supply.
• Follow the guidelines for the safe placement of your pizza oven on a flat surface
that will bear the specified weight of the oven.
• Do not place the pizza oven underneath any structures or materials that are
combustible. The pizza oven is for outdoor use only, in a well-ventilated area.
• When turning on and lighting the oven, please pay close attention to what you are
doing and immediately turn off the oven if you smell gas. Do not place your face or
hands in the opening of the oven, especially when lighting it. Once the oven is on,
all the internal surfaces will become extremely hot and can cause severe burns.
§ Do not block any openings of the oven; do not obstruct the flow of combustion or
air ventilation and do not block off the open front of the oven.!!Do!not!install!the!

RECEIVING THE OVEN
Your oven will be shipped via a common carrier from our Goleta, California Facility. The oven will arrive fully
assembled and crated. You will need a forklift to remove the crated oven. Once off the truck the oven can be moved
with a pallet jack. We will notify you when your oven is shipped and provide you with the tracking information and
the trucking company’s contact number. It is always important to call the trucking company in advance to coordinate
the delivery.
THE OVEN IS VERY HEAVY. MOVING THE OVEN UP OR DOWN A RAMP
OR INCLINE ON A PALLET JACK IS NOT SAFE!

DO NOT TURN THE OVEN ON ITS SIDE
1. USING A CRANE
Once the oven is uncrated and removed from the tie down pallet
it can be lifted and placed using a crane. Rigging for placement
by a crane requires the use of two sling straps to be located
directly beneath the oven base and on opposite sides. The
rigging straps can be attached to an overhead lifting bar or hook.
Each side of the rigging straps must have tension straps to
ensure that the rigging straps remain spread wide at their bases
during the lifting process.
2. USING A FORKLIFT
Be sure to use a forklift rated, and forks the minimum length, as
shown in Appendix A. Fork extensions must be used so the forks
extend through to the opposite side of the stand. The oven is
very top heavy, so be sure to spread the forks as far apart as
possible
3. USING A PALLET JACK
Once the oven has been removed from the delivery vehicle, it
can easily be moved on flat surfaces using a pallet jack. If the
forks don’t extend across the base, use 4” x 4” posts to bridge
the space, placing the forks underneath for support.

DANGER:
Do not place your natural gas connection in a location that may cause a
hazard or injury. Getting caught in a connector or tripping on a component
may cause a serious injury or if the gas continuously flows out of a broken
pipe, regulator or connector, the gas could start a fire and further injury. Turn
gas off at the source or call your fire department for help immediately and
have a professional gas technician make repairs before using the oven.
REQUIREMENTS: NATURAL GAS
Check to make sure that your pizza oven was made to use natural gas. If you are not positive that
you specified natural gas for your oven, please call or write Forno Classico before installing and
using natural gas as your fuel source. Using the wrong fuel source will damage your oven. A pizza
oven configured for LP gas will have orifices that are different than an oven made for natural gas.
If you specified natural gas, your oven was shipped with a regulator to be used during the
installation of your oven. You or a gas technician must provide the correct connector and pipe.

Forno Classico Ovens can be used with gas only or in a hybrid mode. Small amounts of wood can
be added for flavor when the ovens are used in hybrid mode. If you use the oven in the hybrid
mode, you must first bring the oven up to cooking temperature using gas only. Then add small
amounts of wood for flavor. It is important to keep the wood as far away from the burner as
possible. Wood should never be allowed to enter the burner as it is a safety hazard and can cause
severe damage to the burner and oven.

For each specific configuration of oven there is a system that determines what the desired flame height
will be. Each flame height corresponds to a saturated floor temperature. Several factors need to be
accounted for in order to determine this relationship for each oven. Burning wood simultaneously in the
oven will influence the settings below.
USING THE FLAME HEIGHT INDICATOR SCALE
Heat Up Flame: Set Throttle Knob Pointer at “5” (highest setting) on the Flame Height Index Scale until
desired temperature is reached.
Holding Flame: Set the flame height to “3” (~8–9" flame) on the Flame Height Index Scale for desired
temperature of 570–600 °F. Set the flame height to “2” (~5–6" flame) on the Flame Height Index Scale for
desired temperature of 450–480 °F.
Cooking Flame: After introducing the pizza/product into the oven, visually raise the flame to
approximately 3 inches higher than the Holding Flame.
Return the Flame Height Control Knob to the Holding Flame position after removing the pizza/product
from the oven.
THE COOKING FLAME HAS TWO PURPOSES:
1. To bake the top of the pizza/product as fast as the bottom of the pizza/product. 2. To help replace heat
to the floor (hearth) that is lost during production cooking.
Note: The settings recommended on the Flame Height Index Scale for specific flames are based on ovens
that have been installed according to specifications. Individual results may vary slightly.
