FREE-STANDING INSTALLATION
COUNTERTOPS
The Pizza Oven SHOULD NEVER be operated on top of combustible countertop materials. Certain
stone-like composite materials such as Corian®, Formica®, quartz composite materials, etc. have
combustible binders which may permanently discolor or even burn. Other composite materials such as
wood, laminates, etc., and/or those materials with finishes such as oils, varnish, shellac, paints, epoxy or
urethanes, are also combustible and could burn.
CLEARANCES
TO NON-COMBUSTIBLE CONSTRUCTION
As mentioned above, the countertop, and the construction beneath it should be made of non-
combustible materials. Above the countertop, a minimum of 3” [7.6 cm] clearance from the sides and
back of the Pizza Oven to non-combustible construction, such as adjacent walls, is required.
TO COMBUSTIBLE CONSTRUCTION
This appliance should NOT be installed on, over, or next to unprotected combustible construction. Do
not use this appliance under unprotected overhead combustible surfaces.
The countertop, and everything BELOW the countertop must be made of non-combustible materials.
A minimum clearance to combustible materials, such as adjacent walls, is 3” [7.6 cm] on the sides and
the rear of the appliance, ABOVE the countertop surface.
The minimum clearance to combustible materials means that ALL combustible materials must
be outside this 3” [7.6 cm] zone. As an example, if you have an installation with a stucco or tiled
surface and wood-frame construction beneath, or wood-frame walls adjacent or behind, the wood
is considered combustible, even though the Pizza Oven is touching the stucco or tile surface, which
is non-combustible. In extreme circumstances, the wood could potentially get hot enough to burn.
Therefore, ALL the construction must be non-combustible. Adjacent walls above the countertop
should also be non-combustible. If those adjacent surfaces are made of combustible material, they
must be outside this 3” [7.6 cm] zone. The Pizza Oven has a high output, and if installed in a confined
area, the potential to heat up adjacent surfaces is dangerous and could result in property damage.
ISLAND VENTILATION OPENINGS
The enclosure (island) supporting your freestanding Pizza Oven will require a minimum of two
ventilation openings to safely dissipate gas vapors if there is a leak inside your enclosure. Three
openings are preferred at left and right sides, as well as the back. See the GAS CONNECTIONS
section for further information on the gas supply beneath your appliance.
Upper and lower ventilation openings are required. The upper openings must total 20 in² [129 cm²]
in open area and must be located within 5” [12.7 cm] of the countertop and unobstructed. The lower
openings must total 10 in² [65 cm²] in open area and must be located 1” [2.5 cm] or less from the floor.
The upper edge of this lower opening shall be no more than 5” [12.7 cm] above the floor. Louvered
or meshed panels can be used on these openings to keep rodents and debris out of the island. The
openings in these panels must be 1/8”[3.2 mm] diameter or greater.
COUNTERTOP HEIGHT
Your Hestan Pizza Oven comes ready to install onto your enclosure (island) countertop. The
dimensions above show a typical installation height of 36” [91.4 cm]. This will place the oven deck 5.5”
[14 cm] above the countertop. You may want to raise or lower the countertop, or ask your installer to
build a raised non-combustible support to bring the oven deck to a height more comfortable for you to
