Possible Failures - Bartscher GWTH1 Original-Gebrauchsanleitung

o Steel parts should be cleaned daily with warm water and soap, rinsed with clean
water and thoroughly dried. Do not use any agents containing chlorine (bleaching
agent, hydrochloric acid, etc.) or brushes or spatulas from steel wool, which may
leave steel particles. Such materials may be oxidized and leave rust on the device.
o Clean the burner with warm water and gentle cleaning agent.
o Check if the burner holes are not blocked. When required, use the pillow from the
steel wool to remove the deposits without damaging the ignition device.
o Do not use any acidic food products, like vinegar, salt, lemon, etc., as they may
cause damages.
o Use soft and dry cloth to dry and polish the surfaces after cleaning.
o In case of longer break in operation clean the steel parts with moistened cloth and
cover with vaseline oil. Then cover the device with protective foil and place in well
ventilated room.
Maintenance
o Inspect the device at regular intervals. Contact the vendor for assistance in repairs
and regular maintenance (at least once a year).
