The service manual discusses testing of components, maintenance instructions and troubleshooting. Many malfunctions can be corrected by adjusting the pilot burners, main bumpers or thermostats. It is best to attempt to correct these through adjustments rather than immediately replacing parts. When troubleshooting, check diameter of gas connections. Hard plumbing or flex lines must be 3/4” or bigger. With ovens venting into a hood, it is a must to use a stainless steel flue pipe. A draft diverter must be installed when venting directly into the ceiling. The Marsal Gas Oven Service Manual can be found in detail by clicking and downloading the link below.
