It’s a totally fine ruling to say it’s flammable. I’m just saying the spell itself doesn’t say it is. I think treating it like Alchemist’s Fire once ignited is a good house rule. (1d4 damage at the start of each of its turns and can use an action to attempt to extinguish with a DC 10 Dexterity check.)
It’s also not specified as not flammable!
(Also, does it still use animal fat or something as a material component? That’s why we decided it was)
It is specifed as automatic, systematic and hydromatic, though.
But only when combined with lightning.
