Cyclone® HE
The 50-gallon power-vent Cyclone HE is designed to produce more hot water than any commercial gas water heater in its class. Thanks to the internal helical heat exchanger—similar to the design of the industry-leading Cyclone Xi models—the unit achieves 90% thermal efficiency. With its small footprint and easy installation, Cyclone HE delivers heavy-duty performance for numerous light-duty smaller applications, making it a perfect choice for restaurants, offices and other applications.

Cyclone® Xi
Our Cyclone® models deliver extraordinary storage and dollar-savings with models up to 96% efficient. Four units can be manifolded to provide total storage of 520 gallons and total input of 2M BTU — ideal for mid-sized restaurants and 50–300 room hotels. The Cyclone is designed to fit in corners and flush against the wall for maximum installation flexibility.

The Master-Fit® Standard Draft
The Master-Fit® BTR series provides outstanding performance and maximum installation flexibility for both new construction and replacement applications. Each unit is designed to be as much as a foot shorter than the models they usually replace, and multiple options for placement of water connections and low installation clearances are additional installer-friendly features.

Master-Fit® Boosters
The Master-Fit® BTR-151 and BTR-201 are designed for installation in “booster” applications to supply commercial dishwashers with very high temperature water. A booster water heater is normally used in conjunction with a standard water heater delivering hot water at a lower temperature to meet the non-dishwashing needs of a restaurant or other food service application.

Master-Fit® Plus Induced Draft
The Master-Fit® Plus BTN series meets Southern California and Texas low-NOx standards and features induced-draft design. This provides more efficient control of heat through the flue collector. Like all Master-Fit water heaters, the BTN series provides outstanding performance and maximum installation flexibility for both new construction and replacement applications.

Conservationist® Power Direct Vent
The Conservationist® BPD-75 tank-type commercial gas water heater is intended for applications such as small office buildings and duplex apartment homes. The BPD-75 features a power direct vent design with a factory-installed blower. The blower permits sealed combustion direct vent operation with separate venting and air intake runs from outside the structure. The BPD-75 offers installation versatility by allowing venting and intake runs up to 50 feet, using 3? Schedule 40 PVC pipe.

Conservationist® Power Vent
Conservationist® Power Vent has a solid state ignition surface that does not flutter or blow out. Provides increased reliability and efficiency over spark ignition systems. Eliminates the pilot and saves energy. Air is precisely drawn through the combustion control port and exhausted through plastic pipe. Controlling the airflow through the heater enhances and regulates the combustion process. In standby mode, the combustion control port restricts air circulation through the heater.

Conservationist® Induced Draft Low NOx
Conservationist® BTN models are equipped with a blower that produces a power-induced draft of make-up air prior to burner ignition.

Conservationist® BT
Conservationist® BT models provide reliable, efficient service for applications such as office buildings and duplex/fourplex apartment homes.

Conservationist® Large Volume Powered Burner
Conservationist® large volume powered burner water heaters are perfect for large industrial, commercial and institutional applications. This rugged line features up to 2.5 million BTU input and 600 gallons storage. Each model features a PermaGlas® glass-lined tank and multiple anodic protection to prevent tank corrosion.

Conservationist® Small Volume Powered Burner
Conservationist® small volume powered burner water heaters are ideal for mid-sized commercial applications, with inputs up to 740,000 BTUs. They provide outstanding 80% thermal efficiency, thanks to a sealed combustion chamber that reduces heat loss. Other innovations include fully automatic controls and an inspection port for flame monitoring during operation.
