Low Profile Makes Problem Installations Easy

The Sentry Boiler fits into replacement sites with low chimney breeching or low overhead clearance. Sentry models have an integral draft diverter and does not require a separate draft hood. Chimney vent connections heights begin at 38-1/2″, nearly a foot and a half lower than typical natural draft boilers.

Sentry’s low profile permits installation in sites with low chimney breeching or low overhead clearance.
