Description

A traditional wood-fired brick oven with a 34" x 31" stone deck in a flush square metal body.

Marra Forni MS Series metal square brick pizza oven with red front panels and granite ledge on black steel stand, front view (representative image)

The Marra Forni MS34-31W is a wood-burning brick oven for pizzerias and restaurants that want classic wood-fired flavor with an easy-to-clean square exterior. Its 34" x 31" MarraStone deck bakes about 4 twelve-inch pizzas at a time and holds cooking temperatures from 200 to 950°F. Wood loads through the front door, and Marra Forni lists no gas or electrical connection for this model, only the 8" vent collar.

Marra Forni does not list a minimum doorway. The oven is 47-1/2" wide and 55-5/8" deep, so measure every door, hallway and turn on the delivery path and call us before ordering.

Stone hearth deck

The MarraStone deck is refractory brick with volcanic material; it is porous and durable and holds 200-950°F for steady high-volume baking.

Full brick oven inside

The cooking chamber is a hand-built refractory brick enclosure, insulated so heat is absorbed and held for natural convective baking and fast recovery.

Real wood fire

Wood burning gives traditional flavor and lets cooks adjust heat by the amount and type of wood.

Square metal body

Flush, square metal front and side panels give an easy-to-clean exterior and let the oven go into more restricted spaces.

Eyebrow exhaust

An exhaust duct built into the oven opening pulls smoke away from the room while cooks keep a clear view of the deck.

Delivery and setup

  • Price, lead time and freight are quoted per order: call (201) 467-8222 or request a quote.
  • Ships by freight carrier; call us for the shipping weight and crate size before planning delivery.
  • Marra Forni's manual says only trained professionals with proper equipment should lift and move the oven: forklift from the sides; it is top heavy.
  • Install under a Type 1 hood or with Marra Forni's direct-vent system (with exhaust fan), following local codes.
  • A new oven must be cured over 5 days before regular use unless it is delivered pre-cured.
  • Inspect the shipment, including the granite ledge, before signing for it; ledge damage must be reported within 3 days.

Questions buyers ask

Does it need gas or electricity?

The spec sheet lists no gas or electrical connection for this wood-fired model; it needs a proper vent connection or hood. Ask us if you want the optional exhaust fan or interior light box, which are quoted separately.

What can I burn in it?

Only seasoned or dried, untreated solid wood. The owner's manual says never to burn liquid fuel, charcoal, garbage or treated, coated or laminated wood.

Does it need a hood?

It can go under an approved Type 1 hood or connect to a direct vent (150 CFM at 0.01" W.C., 8" collar). Marra Forni's own direct-vent system, which also needs the exhaust fan option, is strongly recommended and quoted separately; code compliance is the installer's responsibility.

Will it fit through my door?

Marra Forni does not list a minimum doorway. The oven is 47-1/2" wide and 55-5/8" deep, so measure every door, hallway and turn on the delivery path and call us before ordering.

How many pizzas does it bake at once?

Marra Forni rates the deck for about 9 eight-inch pizzas, 6 ten-inch pizzas, 4 twelve-inch pizzas or 2 sixteen-inch pizzas per load. Output depends on the product, dough preparation and set temperature.

Does a new oven need curing?

Yes, unless it is delivered pre-cured. The manual lays out a 5-day wood curing schedule that starts with two pieces of wood and adds one more each day.

Why is there no price on this page?

Marra Forni ovens are quoted per order. Call (201) 467-8222 or request a quote for current pricing, lead time and freight to your ZIP code.

What does the warranty cover?

Marra Forni's limited warranty covers defects for 3 years on the dome and deck and 1 year on all other parts. It excludes the granite ledge, normal expansion cracking in the deck and dome, and damage from improper installation or maintenance; travel over 100 miles or two hours is at the buyer's expense.
