Installation
Gas Connection
Connect the oven to the gas line with the proper
type of gas according to Local and National In-
stallation Standards.
SG3240G ovens are rated at 32,2 kW/Hr. (110,000
BTU/Hr.) Each oven has been adjusted at the fac-
tory to operate with the type of gas specified on the
rating plate attached to the left side of the operator
control.
Each oven is supplied with a regulating gas valve
to maintain the proper gas pressure. This valve
assembly is essential to the proper operation
of the oven and should not be removed or re-
placed with another model unless approved by
Blodgett.
