Preheating MQ131 ozone sensor - necessary?

i understand prior using mq!31 ozone sensor, need preheat 24-48 hours, unclear whether have preheat length of time each , every time sensor used. supposed preheat heating element length of time once , you're able take readings @ point thereafter or have preheat every time it's used?

here quote 1 of user manuals:

quote

2.3 long time storage
 the sensors resistance produce reversible drift if it's stored long time without electrify, drift is
related storage conditions. sensors should stored in airproof without silicon gel bag clean air.
for sensors long time storage no electrify, need long aging time stbility before using.

not sure how long "long time storage", maybe 24 hours? i'd need burn in if haven't used @ least day or two.
