INSTALLATION AND OPERATION MANUAL, GAS KETTLES
6.0 SERVICE (Continued)
Should the kettle fail to maintain a vacuum after repeated attempts to establish it, further
checks should be made to see if the pressure relief valve is leaking or if there are any leaks in
the pressure relief valve piping, copper lines going to the pressure switch, pressure gauge or
thermostat fitting.
CONTROL CIRCUIT FUSES
The control circuit is protected by a 3 amp. fuse which is located inside control panel, top right
side above transformer.
Should the unit fail to turn on, check this fuse by removing it and either replacing it or testing it
with a continuity tester. If the fuse is good, check the main power circuit breaker, which should
be external to the kettle.
CONVERTING BETWEEN NATURAL AND PROPANE GAS
WARNING: Fire or explosion hazard can cause property damage,
severe injury, or death.
1. Do not attempt to use a gas control set for natural gas on
propane gas or gas control set for LP gas on natural gas.
2. When making conversion, main and pilot burner orifices MUST
be changed to meet appliance manufacturer's specifications.
Standard- or slow-opening gas controls may be converted from one gas to another. To convert
from natural gas to LP use the 393691 LP Conversion Kit that is included with the VR8304M
Gas Control. To convert from LP to natural gas use the 394588 Natural Gas Conversion Kit
(order separately). Step-opening gas controls cannot be converted.
To convert control from one gas to another:
1. Turn off main gas supply to the appliance.
2. Remove the regulator cap screw and pressure regulator adjusting screw. See Figure 1.
3. Remove the existing spring.
