Features:
- Rugged All-Brass Headers
Resist corrosion, and are easily removed for inspection or service. AB 1953 low-lead complaint. - Cupro-nickel Finned-tube
Single bank, straight through design delivers lowest pressure drop. Integral fins have ten times the heat transfer surface of plain tubes. Cupro-nickel tubes provide superior chemical resistance over copper for tough commercial installations.
- On-off Operation.
- Corrosion Resistant Steel
Fittings are brushgalvanized against rust. Heat shields are corrosion-resistant steel. Jacket has Polytuf powder coat finish. - 24-Volt Controls
Are totally enclosed for protection. Cover is easily removed for inspection and service. - Floating Return Header
Immunizes heat exchanger to thermal shock. - Tube Sheet and “O” Ring Construction
Eliminates the repair and maintenance problems associated with rolling tubes directly into a casting. - Interlocking Refractory Panels
With sealed corners reduce radiation losses. - Stainless Steel Burners
Maintain precise combustion, burn quietly and won’t clog or corrode. - Slide-out Burner Tray
Allows easy inspection and service. - Spark-to-Pilot Ignition
The most dependable ignition method available. - Available for natural gas or propane.
Bypass Options:
- Unitherm Governor (std on 926-1178)
This provides a temperature-activated valve inside the header which varies flow through the heat exchanger. No pump on the heater. Flow comes from an external source.
- H-Style Bypass (std on 1287-1758)
This provides a larger manually-set bypass to bring heated water back to the inlet, raising the temp inside the heat exchanger. For size 1287, the H-bypass is horizontal with a rear-mounted pump. For sizes 1414-1758, the H-bypass is vertical with a front-mounted pump.
- None (field-supplied)
Protection provided by others and mounted in the field. - Cold-Water Run (CWR)
This approach uses digital controls to vary the performance of a variable-speed pump which governs how much heated water is returned to the inlet. Performance is adjusted in real time.
