The failure allowed heat and gasses to “escape into the pipe chase and ignite structural members,” of the home at 26 Runaway Brook Road, Jennifer Mieth, a spokeswoman for the office, said.
Two firefighters suffered minor injuries in the fire and no residents were injured, Mieth said.
The home is considered a total loss, Mieth said.
A lack of nearby hydrants made it difficult for crews to get water past the home’s 900-foot-long driveway. Firefighters relied on tanker shuttles to deliver water to the scene, Mieth said.
