Any ideas thanks.
The SAFETY SAIL SWITCH senses airflow, (or lack of) and shuts off gas to prevent overheat. IF BATTERY CHARGE Low/ defective, Fan runs SLOW, SAIL shuts off gas to prevent OVERHEAT; since you get heat, 1) suspect problem with BATTERY/ CHARGE/ LOW VOLTAGE? 2) ALSO Make sure TANK VALVE FULLY OPEN, if not, flame maybe failing after GAS PRESSURE falls off?
