Fire hit a classroom at Manchester Middle School this morning.
Crews from new Franklin and Clinton responded just after 8AM, where the flames were shooting through the roof and heading up the wall of a room that was detached from the rest of the school.
The room was vacant at the time, and the blaze was brought under control in about 15 minutes.
Officials determined some insulation in a wall was too close to the heater, which caught fire.
No one was hurt. Damage is estimated to be about 150-thousand dollars, and limited to the auxiliary building.
