6.0 - GENERAL MAINTENANCE
WARNING - Disconnect the Power Supply Before Cleaning and Servicing.
6.1 Introduction
This section presents an overview of maintenance procedures for various components of
a Guspro Heat Cleaning Oven. It is recommended that maintenance inspections of the oven be
carried out on a regular basis and that defective parts should be immediately replaced.
6.2 Gas Burners
This section deals with cleaning and servicing of the gas burner assembly for Guspro E
burners. Maintenance tips for the following components are included: Spark Electrode, Blower
Mechanism, Air Flow Switch, Automatic Gas Valve/Actuator and Air Damper.
6.2.1 Electrode Assembly
The most common cause of the burner failing to light is due to an electrode malfunction.
This can normally be attributed to the following:
• Incorrect electrode sparking gap.
• Cracked insulation on electrode.
• Surface rust or dirt on the burner nozzle at the point where the electrode sparks.
6.2.2 Electrode Gap
Warning: Be sure to turn off electrical power to the burner before proceeding. The
electrode transformer generates a minimum of 6000 V and 20 mA.
Remove the electrode. Grind or file the electrode tip on a 45
o
angle. Check the porcelain
for cracks.
Inspect the position of the burner cup nozzle inside the housing by looking into the
mounting hole of the electrode. Check to ensure that the burner cup and nozzle is centred in the
housing and scrape off any surface rust, dust, soot etc. with a screwdriver.
Before installing the electrode back in the burner housing, inspect the connector of the
ignition cable to ensure that it fits properly.
To set the electrode gap, drop the electrode to the bottom and mark the ceramic with a
pencil. Move the electrode up 1/8" and tighten the screw.
