TOLERANCE > TRU-FLOW™

The boiler will operate without producing dangerous emissions with the flue or air inlet significantly blocked. The boiler will react to a change in air or flue flow, from any cause, by reducing its input while maintaining high combustion quality. This feature, while providing a high degree of safety, reduces sensitivity to flue installation and allows use in areas of variable air inlet pressure with no degradation in performance.
