- Note to Gas Technician
- WARNING: DO NOT perform any pressure tests on this appliance or the regulator supplied in excess of 1/2 PSIG.
- For fixed fuel supply systems. RE: Pressure tests
- A. The appliance and its individual shut-off valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psi. (3.45 kPa).
- B. The appliance must be isolated from the gas supply piping system by closing it’s individual manual shut-off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psi. (3.45kPa).
- 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”.
- Note: For LP (Liquid Propane) applications, the specified BTU’s are calculated at a manifold pressure of 11 inches W.C.. For NG (Natural Gas) applications, the specified BTU’s are calculated at a manifold pressure of 4 inches W.C..
- For reference, orifice sizes and manifold pressures are indicated on the rating plate of the appliance.

- 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. Any attempt to fit the regulator(s) with anything other than the mating T...
- • Will not allow gas to flow until a positive seal has been made.
- • Has a thermal element that will shut off the flow of gas if subjected to temperatures between 115 and 150 C (240 & 300 F).
- • Has a flow limiting device which, when activated, will restrict the flow of gas to 10 cubic feet per hour (25000 BTUs).

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. There should be little noise and no lifting.
•
The inner cone should be 1/4 inch high.
•
The outer cone should be 5/8 inch high.
Visually inspect the flames in your pizza oven and adjust if necessary, using the
instructions below.
IMPORTANT:
A sooty flame is usually caused by dirt, debris or spider nests blocking the
air shutter or orifice. This is a dangerous condition. The pizza oven should NOT be used
until the problem is rectified. If you are not comfortable addressing the issue yourself,
please hire a licensed technician or contact Crown Verity Service at 1-888-505-7240.
To Clean the Air Shutter:
Turn off the gas supply shutoff valve or close the main valve on the LP cylinder. Ensure
the pizza oven control knobs are in the OFF position.
If your pizza oven is equipped with side and or front shelves, remove the shelves and
carefully place them on their backs to avoid scratching the surfaces. Next, remove the
faceplate of the burner box by removing the four screws on the outside edge of the
face. Once the four screws are removed, gently lift up and forward to remove the face.
Place the face down on its back to avoid surface scratches.
The shutter is located at the end of the burner tubes closest to the gas orifice.
Use a flashlight to view the screened openings of the air shutter from and remove any
obvious obstructions from the screen protecting the air shutter.
To Adjust the Air Shutter:
Leave the gas supply shutoff valve in the OFF position or leave the main valve on the LP
cylinder in the closed position. The pizza oven control knobs should also remain in the
OFF position.
