Installation & Operation Manual
30
The gas supply should have a gas meter and regulator large enough to handle all of the gas appliances,
such as the furnace, hot water heater, and ovens, in operation at the same time. Add up all of the kw
ratings to determine the total load. (See chart for supply requirements).
The electrical service should be three 20 amp 240VAC single phase circuits (2 poles with ground). This
provides a separate circuit breaker and single receptacle for each oven deck. The use of single
receptacles eliminates the possibility of plugging an additional device into oven circuit and will in most
jurisdictions eliminate need for a ground fault receptacle. If possible, leave room to the right of the ovens
for easy access and connection of gas and
electric lines. The electrical outlets (Item 1) can also be
located to the left of the gas line.
Figure 18: Gas Service view
The picture above shows a close-up detail of the gas service. 3/4" gas hose assemblies with quick
disconnects for each oven deck will be installed at each valve (item 9) during the oven setup and
installation. Alternatively, items 5-10 can be assembled to the left instead of to the right, as shown
in the upper right of the figure.
