13. To remove the heater cartridge, unscrew it from its threaded hole.
14. The thermostats can be replaced by removing the nuts securing them to the ramp block.
If either thermostat or the heater cartridge is being replaced, check all components (especially the plastic
ones) for signs of heat damage or corrosion. We recommend replacing the sheath when replacing the
heater cartridge.
