My Raypak electronic ignition heater has a liquid crystal keypad/decale which needs to be replaced every year. The digits just stop showing. Ordering the part on line is not an issue, other than the expense, but doing it and reinstalling it every year is a PITA.
The heater is exposed to the elements. Will a rain cover help?
This is the keypad as it shows in the heater. It's Raypak part # 009184F.
