Girard GSWH-2 filter screen or decalcify maintenance

Use this when Girard GSWH-2 guidance points to owner-accessible filter-screen cleaning, decalcifying, or visual maintenance before service.

Owner-safe checklist

Turn the water heater off before owner-accessible filter, screen, or decalcifying work.
Use only the Lippert/Girard maintenance procedure and materials allowed for the model.
Do not open appliance service compartments or disturb gas, electrical, blower, valve, or controller parts.
Call Lippert/Girard or a qualified technician if flow, temperature, or visible condition does not recover after allowed maintenance.
