FARMINGTON – Voters will be asked to approve transferring another $10,000 from the undesignated fund tonight to go toward buying a new boiler for the municipal building.

Taxpayers already agreed to take $25,000 from the fund last month for the purchase, which was originally slated to be a set of three small Marconi Bantam boilers. But since then, Town Manager Richard Davis said, town officials have been told those boilers won’t work in the building.

“They’re not designed for this type of application,” Davis said. “It’s (because of) something about the way it’s configured.” They were really designed for residential use, he said.

So the selectmen decided to go to the next-lowest bid they’d received, for a $35,000 boiler from Ranor Inc. of Jay.

Davis and other town employees have said before they don’t think it’s smart to rely on the 30-year-old boiler now heating the building. The town has spent more than $19,000 repairing it in the past three or four years, David said. The boiler had a projected life span of 20 years.

The special town meeting is scheduled for 7 p.m and will be held downstairs in the community building.
