FEATURES AND BENEFITS
Compact Firetube Design
The Model CFC-E boiler is a high mass, vertical down fired robust firetube boiler. The internal
extended-heating surface tubes provide very high levels of performance in a compact space. The
large water volume makes the CFC-E ideal for variable flow primary pumping systems.
Large Water Volume
The large water volume makes the CFC-E ideal for variable flow primary pumping systems.
Advanced Technology
Tubes, tube sheets, and combustion chamber are constructed from UNS S32101 duplex stainless
steel. Tubes feature AluFer tube inserts for optimal heat transfer.
Advanced Fireside Construction
The extended heating surface design provides the ideal solution for the demands of a condensing
boiler and helps to recover virtually all the latent heat of the flue gas. Each tube consists of an outer
stainless steel tube (waterside) and the AluFer extended heating surface profile on the flue gas side.
High Efficiency
With the extended heating surface tubes the CFC-E boiler will provide fuel to water efficiency of up to
99% at low fire and 95% at high fire with 80 degrees F return water temperature.
Ease of Maintenance
The powder coated steel casing is designed for easy removal and re-assembly. As shown in Figure 1,
the burner is hinged and is provided with hydraulic pistons for simple opening for service of the spark
electrode, inspection of the burner cylinder, tubes and combustion chamber.

Quality Construction
ASME Code construction ensures high quality design, safety, third party inspection, and reliability,
and accordingly bears the ASME Section IV “H” stamp.
Premix Technology
The burner utilizes “Premix” technology to mix both gas fuel and combustion air prior to entering the
burner canister, with air leading the fuel during burner firing transitions. Combined with the surface
combustion burner and self-regulating gas valve-venturi fuel-air ratio control, this technology provides
very low emission levels, exceptionally safe operation, and nearly 100% combustion efficiency.
Full Modulation
The variable speed combustion air blower with ECM technology provides modulated firing for precise
