Turndown Ratio
10 to 1

with a modulating burner combustion system and two independent boilers working together as one unit, the Mod Con Double Stack boiler is able to operate at a true 10:1 turndown ratio, saving fuel and providing comfort levels efficiently and evenly

Venting

Equipped with concentric venting, the Mod Con Double Stack requires only one exhaust connection through the wall or roof for exhaust vent piping

Complete flexibility with the ability to vent up to 150 ft.

Lower exhaust temperatures due to high efficiencies allows for the use of PVC or other plastic venting materials, saving on installation cost and time
