MODEL GH SERIES HEAVY DUTY GAS RANGES
KEEP THIS MANUAL FOR FUTURE REFERENCE
Vulcan ranges and ovens are produced with quality workmanship and material. Proper installation,
usage and maintenance of your range will result in many years of satisfactory performance.
The manufacturer suggests that you thoroughly read this entire manual and carefully follow all of the
instructions provided.
A rating plate is located on the lower left-hand corner of the front frame behind the bellcrank. The rating
plate states the model number, serial number and type of gas the range requires.
Motors in Vulcan convection ovens are permanently lubricated and require no additional maintenance.
Should it be necessary to disconnect the gas line strain relief at the rear of the range in order to perform
service procedures, turn off the gas supply before disconnection. Reconnect the strain relief before
turning the gas supply on and returning the range(s) to their installation position.
