Raypak’s focus on customer satisfaction goes beyond product design. Like all Raypak boilers, every Hi Delta is factory-fire tested, assuring reliable start-up upon installation. For over 60 years, Raypak professionals have earned their reputation as The Hot Water Management Experts.
On-Board Diagnostic Center Raypak’s Hi Delta (302 thru 2342) comes equipped with a microprocessor-controlled diagnostic control center that displays its information on a 2x20 character LCD display in plain English. This control monitors system safeties, ignition faults and system status, while storing up to 16 reported faults.
Sidewall Vent Category III Options SureRack 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.
