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.
Connection:
A quick-connect hose is provided to support the connection to a bulk
supply.
WARNING:
The Operating Pressure of the appliance is 11.0" W.C. A step down regulator MUST
be used on an LP house system to reduce the pressure down to 11.0" W.C. for the pizza oven.
IMPORTANT:
Always close the gas supply shutoff valve before disconnecting the pizza oven
gas supply hose.
IMPORTANT:
An installer-supplied safety shutoff valve MUST be installed on the liquid
propane gas supply line for the pizza oven. The valve should be easily accessed and located
between 3 and 20 feet away from the oven. All gas connections should be made by a licensed
technician. The installation and all installer-supplied parts must conform to local codes. In the
absence of local codes, the installation and all parts should conform to the National Fuel Gas
Code, ANSI Z223.1/ NFPA 54 or Natural Gas and Propane Installation Code, CSA B149.1.
IMPORTANT:
Diameter and length of the gas supply pipe may limit the pressure and BTU
delivery of gas to the oven. The installer must ensure proper delivery to the pizza oven or it will
not operate properly. The appliance and its individual shutoff valve must be disconnected from
the gas supply piping system during any pressure testing of that system at pressures in excess
of 1/2 psi (3.5 kPa). During any pressure testing of the gas supply piping system at test
pressures equal to or less than 1/2 psi (3.5 kPa), the appliance must be isolated from the
system by closing its individual manual shutoff valve.
All pipe sealants must be of an approved type
.
Leak Testing
Although all gas connections on the pizza oven are leak tested at the factory prior to
shipment, a complete test must be performed:
A.
After installation due to possible mishandling during shipping or installation.
B.
Periodic checks are also required every time the propane cylinder is refilled, any
gas component is changed or at least once a year.
