WARNING: DO NOT install any gas handling components/materials affected by elevated temperatures within 18” of any side of this appliance. Make sure that the supply line is of adequate capacity to accommodate the higher inputs of the pizza oven before you begin. They are significantly higher inputs than average appliances of this type. The use of a typical corrugated metallic appliance connector is recommended for connecting the appliance, with a minimum diameter of 1/2”.
PAGE 13
Liquid Propane Gas Requirements (Cont’d) WARNING: For Propane Gas Models: Your pizza oven is designed to operate on L.P. (propane) gas pressure regulated at 11” water column. The regulator(s) supplied with the pizza oven is set to this pressure and must be used. Connection: The Type I (Q.C.C.1) cylinder valve is recognizable by the large external thread on the outlet part of the valve. Standard valves do not have these exterior threads.
PAGE 14
Liquid Propane Gas Requirements (Cont’d) The regulator probe also contains a flow-sensing element, which will limit the flow of gas to the regulator to a manageable amount (10 cubic feet per hour) in the event of a hose or regulator failure, or a leak. If it is evident that the flow-limiting device has activated, the cause of the excessive flow should be determined and corrected before using your grill again.
PAGE 15
Natural Gas Requirements Verify the type of gas your pizza oven has been configured for by the factory by checking the rating plate on the oven. Pizza ovens configured for natural gas (NG) are orificed differently than ovens configured for liquid propane (LP) gas. Pizza ovens configured for use with natural gas are shipped with a hose, regulator and quickconnect fitting. WARNING: For Natural Gas Models: Your pizza oven is designed to operate on natural gas (NG) pressure regulated at 4” water column.
PAGE 16
Bulk Supply Liquid Propane Gas Requirements Verify the type of gas your pizza oven has been configured for by the factory by checking the rating plate on the oven. Pizza ovens configured for liquid propane (LP) gas are orificed differently than ovens configured for natural gas (NG). For pizza ovens configured for use with bulk LP tanks, a regulator is not supplied. To purchase these options, please contact Crown Verity at 1-888-505-7240.
PAGE 17
C. Immediately check for leaks if you smell gas. WARNING: Never use an open flame to look for a leak. Perform the leak test outdoors in a well-ventilated area. Extinguish all open flames and keep away from any heat or ignition sources. DO NOT SMOKE! Use only a 50/50 mixture of liquid soap and water for leak testing. IMPORTANT: Owners should only check for leaks on the gas connections that are external to the pizza oven.
PAGE 18
Warning!- Natural Hazard - Spiders Spiders and other insects are attracted by the smell of gas and could make webs or nests in the burners. This could partially or completely block the flow of gas through the venturis and is indicated by a smoky, yellow flame, and/or a burner that is difficult or impossible to light. Ultimately, it may cause the gas to burn outside the venturis, which can seriously damage your pizza oven.
PAGE 19
Locating the Pizza Oven (Cont’d) • DO NOT place the pizza oven on any surface that would allow the pizza oven to easily or inadvertently change position. When in use, always have the casters in the locked position. • For natural gas and bulk propane models, NEVER place the pizza oven where the gas hose creates a safety hazard. Tripping over an exposed gas hose may create a gas leak, cause the oven to tip or topple over or create other serious safety hazards.
PAGE 20
IMPORTANT: Do not build the pizza oven into any type of enclosure. Proper air circulation in and around the pizza oven is critical to its operation. Maintain at least 12 inches of clearance around the sides and back of the pizza oven, and 12 inches above the top. Do not obstruct the open space below the pizza oven. NEVER place the pizza oven underneath an overhead combustible surface. The pizza oven must be placed on top of a non-combustible surface.
PAGE 21
General Operating Procedures The pizza oven reaches operating temperatures in approximately 20 minutes but may vary depending on environmental conditions. The ideal surface temperature of the cooking stones, specifically for pizza, is between 500-525 degrees Fahrenheit, however for compliance requirements, the temperature gauge for the oven is specific to the air temperature.
PAGE 22
Additional Cooking Tips (Cont’d) • Do not leave an assembled pizza on the peel longer than absolutely necessary. This can lead to the pizza sticking to the peel. • Cook thin to medium crust pizzas directly on the cooking deck. • Use multiple, smaller “flicking” gestures to coax the pizza off the peel into the oven. Trying to do it with one, larger gesture is more likely to dislodge pizza toppings. • Do not overload a thin-crust or medium-crust pizza with too many toppings.
PAGE 23
Lighting Your Pizza Oven Before lighting your pizza oven, be sure you have followed the instructions in this manual regarding proper setup, placement, gas connections leak testing and safe operation, all of which precede this page. IMPORTANT: Do not use the pizza oven if the odor of gas is present at any time. Follow leak testing procedures before using the pizza oven. Standard Lighting Procedure: • Position the wind guards in the fully open position.
PAGE 24
Manual Lighting Procedure: AC B • Open the pizza oven doors and position FIGURE 3. VALVE POSITIONS D on the sides of the oven. • Make sure the main burner valve is the OFF position (See Figure 3.). • Turn the main gas supply on and wait 15 seconds. • Turn the pilot valve to the on position. • Insert a barbeque lighter into the hole located behind the wing door on the face of the pizza oven (see Figure 4). • Visually inspect to see that the pilot tube is lit.
PAGE 25
Burner Adjustments Every burner is tested and adjusted at the factory for proper performance. If a burner is not operating properly, it may be due to variations in the local gas supply or because of an obstructed air shutter or orifice. Flames should be stable without lifting from the burner. The flames should burn cleanly without creating any sooty residue. Burner Flame Characteristics: • The flame should be blue and stable with only a small amount of orange, if any, at the tips.
PAGE 26
With the face removed, you will also need to remove the cooking stones to have clear access to the burners. Using a screwdriver, loosen the lock screw (see Figure 6). Be careful not to remove the lock screw. Once loose, you can rotate the air shutter to adjust the amount of air entering the venturi. Turn on the gas supply valve or open the main valve on the LP cylinder. Following the lighting instructions, light the burners to be adjusted.
PAGE 27
