audible tone.
• The red indicator light on the valve flashes (approx. every 10 seconds).

• The fire will stop working, or will only work intermittently.
• The handset (or valve) may give error codes, which may or may not be correct.
• The batteries may leak and cause permanent, irreversible damage to the electronics meaning a
replacement item must be sought (not covered by warranty).
