The re-placement hose or tubing will be specified by Delta Heat. (See pages 12-13 for how to gain access to tubing). If the oven is to be stored indoors, disconnect the gas supply cylinder and leave the cylinder outdoors.

WARNING

• DO NOT PLACE MORE THAN ONE CYLINDER IN THE ENCLOSURE AT ANY TIME. DO NOT USE A DENTED OR RUSTED LP CYLINDER.
• DO NOT STORE SPARE LP GAS CYLINDERS UNDER OR NEAR THIS APPLIANCE. NEVER FILL THE CYLINDER BEYOND 80 PERCENT FULL.
• FAILURE TO DO SO, IN A FIRE CAUSES DEATH OR SERIOUS INJURY MAY OCCUR.

If LP gas is the desired gas type for your Pizza Oven, please note that Delta Heat does not provide the LP gas cylinder. If an LP gas cylinder was to be used in this installation, we strongly recommend the following guidelines:

An enclosure for the LP gas cylinder must be vented on the level of the cylinder valve and at floor level. The effectiveness of the opening(s) for purposes of ventilation shall be determined with the LP gas supply cylinder in place. This shall be accomplished by one of the following:

1. One side of the enclosure shall be fully open; or
2. For a cylinder enclosure having four sides, a top, and a bottom, and intended for installation in a built-in enclosure:
3. at least one ventilation opening shall be provided on the exposed exterior side of the enclosure located within 5 in (127mm) of the top of the enclosure and unobstructed. The opening(s) shall have a total free area of not less than 1 in²/lb (14.2 cm²/kg) of stored fuel
4. at least one ventilation opening shall be provided on the exposed, exterior side of the enclosure 1 in (25.4 mm) or less from the floor level and shall have a total free area of not less than 1/2 in²/lb (7.1 cm²/kg) of stored fuel The upper edge shall be no more than 5 in (127 mm) above the floor level.

• every opening shall have a minimum dimension to permit the entrance of a 1/8 in (3.2 mm) rod.

LP GAS CONNECTION TO BULK LP PIPED SYSTEMS:

A bulk LP piped system is typically a central LP tank detached from the home that feeds the entire household. Those systems are normally equipped with a high-pressure regulator at the tank and low-pressure regulators close to the home. All gas line connections must comply with the Standard for Connectors for Outdoor Gas Appli- dances and Manufactured Homes, ANSIZ21.75, CSA 6.27, and be suitable for outdoor installation. The maximum length of the connection shall be 6 ft. (1.82 m).

NATURAL GAS INSTALLATION

The installation must conform with local codes or, in the absence of local codes, with either the N ational Fuel Gas Code, ANSI Z223.1/NFPA 54, Natural Gas and Propane Installation Code, CSA B149.1 or Propane Storage and Handling Code, B149.2.

1. This gas appliance and its shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at the test pressures over 1/2 psi (3.5 kPa).
2. This appliance must be isolated from the gas supply piping system by closing its manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psi (3.5 kPa).

If the gas oven is factory built for NG; the regulator supplied is set for 4” in wc. The regulator is convertible to 10 in wc (2.49 kPa) for plumb-in system LP application. Do not use with a 20 lb LP cylinder. Make sure that the regulator is set for the correct gas type (see page 4). To check, remove the brass hex cap. You will find the conversion plastic pin attached to the cap to the underside of the cap. If the disc (1/2 in diameter) of the pin is close to the cap, then the regulator is set for Natural Gas. If the disc is at the tip of the pin, away from the brass cap, the regulator is set for system LP application. To convert to NG, remove the plastic conversion pin and invert and replace it in a manner such that the disc is close to the brass cap. For both NG and LP, the maximum inlet pressure is 14 in wc (3.5 kPa).

A typical NG installation is shown below. Make sure that the factory-supplied regulator is used and installed with the arrow mark on the regulator pointing towards the oven. Do not use any replacement regulator other than that specified by DELTA HEAT. Use only pipe sealants that are approved for use with NG and LP gases. An installer-supplied gas shutoff valve must be installed in an accessible location.

BUILT-IN DIMENSIONS

The Pizza Oven can be installed into an existing or new built-in enclosure. Built-in model enclosures must be made of non-combustible masonry materials.
When installing the Pizza Oven as a built-in unit, careful consideration must be taken with the materials to be used in the construction of the enclosure. The image below shows a typical built-in installation.

A minimum perimeter of 1 in clearance to the sides of the oven. A 4 in x 4 in opening at the right rear corner of the unit is required for access to the gas hook-up be- low the oven.

CLEANING & MAINTENANCE

IMPORTANT STAINLESS STEEL & GENERAL PRODUCT CARE

To keep your Delta Heat products free of surface corrosion and in good working order, it is important to take additional precautions under certain conditions. If your Delta Heat products are located in corrosive conditions, such as:

• A coastal environment where corrosive salty air is
• Near a swimming pool, hot tub, or water feature with exposure to corrosive pool chemicals and/or chlorinated water.
• Areas where muriatic acid (hydrochloric acid) or other corrosive cleaning solutions are used to clean concrete and masonry.
• Areas where corrosive masonry dust and debris are created by cutting stone or mixing

These conditions can create a highly corrosive environment that will cause the corrosion-resistant type 304 stainless steel to develop surface oxidation, corrosion, or rust.

Delta Heat products have been tested in saline solutions, highly chlorinated solutions and have been tested against exposure to highly acidic foods. The test results proved that type 304 stainless steel can withstand exposure over prolonged periods. However, the conditions outlined above, along with neglect, can lead to surface corrosion or rust.

It is recommended that your Delta Heat products be kept dry and covered when not in use. This is even more important when long-term storage is intended.

Do not allow food particles or grease to be left inside your Delta Heat products. These can attract rrodents which are unsanitary and are likely to cause physical damage by chewing on the wiring, which can cause permanent damage to the electrical components.

If you are located along the coast or in the desert, wind-driven sand is extremely abrasive and can pit and scratch the stainless steel. Keep your Delta Heat products covered when not in use.

When routine cleaning, maintenance, and awareness of the conditions outlined above, you can enjoy many years of service from your Delta Heat products.

If surface corrosion has developed on the stainless steel, it is typically not the stainless steel that is corroding but corrosive particles that have been deposited on the surface.

Delta Heat ovens are made of all welded stainless steel. It is non-rusting and non-magnetic. Never clean the stainless steel when it is hot. After the initial use, certain areas of the oven may discolor. This is a normal discoloration caused by the intense heat given off by the burners.

Specks of grease can gather on the surface of the stainless steel and get bbaked on These can be removed by using a mild abrasive pad with a stainless steel cleaner. Use the mildest cleaner and always scrub in the direction of the grain. Do not use steel wool to clean the stainless.

Do not use abrasives on the polished highlights. Be extra careful when cleaning around the high- lights. Metal polisher or mild chrome cleaner can be used to bring back the luster on highlights. To touch-up minor scratches in the stainless steel, sand the affected surface very lightly, with 100-dry grit emery sandpaper in the direction of the grain.

• REAR BURNER
  The Rear Burner is made of heavy gauge stainless steel and can be soaked in water and cleaned with a wire brush. Check every port hole for clogs. Use a wire pin to clean out clogged ports. Make sure the burner is dry before reinstalling it back into the oven.

• HEARTH BURNER
  The Hearth Burner is located below the Pizza Stones. It should be checked periodically for cracks or any food particles that make it below the Pizza Stones.

• PIZZA STONES
  The Pizza stones should be kept clean and clear of any burnt-on residue from previous cooks. Most residue will burn away given enough time, but for some stubborn spots, gently brush down the stone with a hard bristle brush.

DO NOT GET THE STONES WET!!!

SPIDER AND INSECT WARNING

Spiders and other insects can nest in the burners of this and any other outdoor appliance, which causes the gas to flow from the front of the burner. This dangerous “condition” can cause a fire inside the oven body, damaging the oven and making it unsafe to operate. Inspect the burners once a year or if the oven has not been used for more than one month or if any of the following conditions occur:

1. The smell of gas in conjunction with the burner flames appearing
2. The oven does not reach
3. The oven heats
4. The burners make popping
