Marra Forni MS34-31G 47-1/2" Gas Brick Pizza Oven, Metal Square, 34" x 31" Stone Deck, 4 x 12" Pizzas, NG or LP
Description
A gas-fired brick oven with a 34" x 31" stone deck and a flush square metal body made for tighter installations.
The Marra Forni MS34-31G is a gas brick oven for pizzerias, restaurants and bakeries that want Neapolitan-style results with an easy-to-clean square exterior. Its 34" x 31" MarraStone deck bakes about 4 twelve-inch pizzas at a time from 200 to 950°F, run by a MarraSmart touchscreen with timed on/off and menus. It burns natural gas or LP (up to 145,000 BTU/H) and plugs into a standard 110V outlet for the controls.

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.
MarraSmart controls
The programmable touchscreen controls cooking conditions, runs timed on/off and saved menus, and shows QR codes for service and maintenance videos.
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.
- A licensed installer connects the 3/4" gas line with the required regulator and quick-disconnect hose; the controls plug into a 110V outlet.
- 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
What gas and power hookups does it need?
A 3/4" NPT gas supply (natural gas or propane, 10-14" W.C. inlet pressure) with a gas regulator and a quick-disconnect hose, plus a standard 110V, 15 A outlet for the NEMA 5-15P cord. Marra Forni recommends against a GFCI outlet because burner ignition can trip it.
Natural gas or propane?
Either. Choose the fuel type when you order; the burner orifice differs (0.173" for natural gas, 0.125" for propane).
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 controller runs a 5-day curing cycle (300°F up to 700°F); do not speed it up or switch the oven off during it.
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.
