Sidewall Vent Vertical Venting Category III Category I (Type B) Options SureRackTM Kit The perfect solution for today’s most space challenged equipment rooms. Stacking two Hi Delta 2342 boilers provides over 4.6MMBTU in just over 26 square feet plus clearances. All components (except pumps and PRV’s) are contained inside the cabinet, so there won’t be any gas valves or fans hanging off the unit. The units remain fully serviceable even while racked.
