Not really. They do not worship fire, any more than Christians worship wood when they pray in front of a cross.
To them, fire is the symbol of God. Considering that in the Bible, God appeared as a burning bush, led the Israelites as a pillar of fire, and in the New Testament we also see God appearing as fire, it's not so different from Christian views:
When the Day of Pentecost had fully come, they were all [a]with one accord in one place. 2 And suddenly there came a sound from heaven, as of a rushing mighty wind, and it filled the whole house where they were sitting. 3 Then there appeared to them [b]divided tongues, as of fire, and one sat upon each of them. 4 And they were all filled with the Holy Spirit and began to speak with other tongues, as the Spirit gave them utterance.
It is interesting the tie between the metaphors. I didn’t say they worshiped the flames, although in a sub-Christian context it would be understandable if they did.
It’s customary in Jewish synagogues to have an “eternal lamp” burning all the time. The one I used to go to (how I became Christian is another story) used an electric one. Which would burn unless the electricity went out or the bulb burned out. At that time I wondered about whether they could use what we know now as an uninterruptible power supply.
