GAS CONNECTION - NATURAL GAS (NG)
NEVER CONNECT THE PIZZA OVEN TO AN UNREGULATED GAS SUPPLY.
Before proceeding, ensure the oven is fitted for natural gas. Connecting to an improper gas type will re-
sult in poor performance and increased risk of damage or injury.
Total gas consumption (per hour) with all burners set on “HI” is a follows:
•
Hearth Burner 18,800 BTUH
•
Log Burner 16,800 BTUH
The installation of this appliance must conform with local codes or, in the absence of local codes, to the
national fuel gas code, ANSI Z223.1a-1988. Installation in Canada must be in accordance with the
Standard CAN/ CGA-B149.1 Natural Gas Installation or CAN/CGA-B149.2, Propane Installation Code.
Manifold pressure with NG:
Operating: 4.0” W.C. (.14 PSI)
Non-operating: 4.5” W.C. (.16 PSI)
Optimum pressure: 7.0” W.C. (.25 PSI)
NOTE: To ensure proper heating performance of this appli-
ance, verify that the gas line supply pressure is adequate
(7.0” W.C. supply pressure is preferred) to maintain 4.5”
W.C. manifold pressure.
Use a minimum 1/2” ID flex hose to prevent gas starvation.
(See Figure # 5)
LP GAS CONNECTION TO LP PIPED SYSTEMS:
An LP piped system is one with a large central LP tank that feeds the entire household. Those systems
are normally equipped with a high pressure regulator by the large LP tank and low pressure regulators
close to the home.
