Installation, Operation, and Care of

INFRARED BOOSTER GAS WATER HEATERS

SAVE THESE INSTRUCTIONS

GENERAL

The Infrared Booster Gas Water Heaters (available for natural gas or propane) provide 180°F rinse water for commercial dishwashing machines. Health codes and NSF permit 180°F (minimum temperature) water to be used as a sanitizing rinse for utensils and dishware used in restaurants and food-serving operations. Water enters the gas booster water heater at the inlet water connection, circulates through the gas heat exchanger and stainless steel tank, and constantly maintains the 180°F minimum water temperature at the outlet connection. The table, Delivery Rates @ 180°F, indicates the maximum amount of hot water that can be delivered by the various Booster Heater models, depending on the incoming water temperature.

Rinse water volume requirements for various commercial dishwasher models and operating rates are available from your authorized Hobart dealer.
