1-2 Part No. 750-363
1.1 CFLC FEATURES AND BENEFITS
Compact Firetube Design
The CFLC boiler is a two pass horizontally fired durable Firetube boiler. The extended heating surface tubes
provide for very high levels of performance in a compact space. The boiler is designed to fire natural gas.
High Efficiency
With the extended heating surface tubes the boiler can produce fuel to water efficiency of up to 99%
depending upon operating conditions.
Advanced Construction
Constructed to ASME standards, the CFLC Boiler will provide many years of trouble free service.
First pass tubes are made from SA178A Carbon Steel and are of rifle design for maximum heat transfer.
Second pass tubes are made from UNS S32101 Duplex Stainless Steel with AluFer extended heating
surface inserts for maximum heat transfer.
Dual Temperature Return
Two return pipes - high and low temperature - allow condensing performance with as little as 10% return
water at condensing temperature.
Ease of Maintenance
The steel enclosures are readily removable for access to all key components. A hinged burner provides
access for burner maintenance and fireside inspection.
Quality Construction
ASME construction ensures high quality design, safety, and reliability.
ISO 9001 certified manufacturing process ensures the highest degree of manufacturing standards is always
followed.
Full Modulation
The burner and combustion fan modulate to provide only the amount of heat required, providing quiet and
efficient operation under all conditions.
Premix Technology
The CFLC boiler utilizes "Premix" technology to mix both fuel and combustion air prior to entering the firing
chamber. This technology provides clean, efficient combustion with very low emission levels.
Designed For Heating Applications
The pressure vessel is constructed of durable ASTM Grade Steel and Stainless Steel materials to provide
many years of operating life.
Thermal shock resistant design with large water volume and low pressure drop is ideal for primary variable
flow applications.
1.2 STANDARD EQUIPMENT
1.2.1. The Boiler
The boiler is designed for a Maximum Allowable Working Pressure (MAWP) of 160 psig (11 Bar) in
accordance with the ASME Code for Low Pressure Section IV Hot Water Boilers and is stamped accordingly.
Operating pressure shall be less than 144 psig (9.9 Bar).
The vessel is mounted on a steel base with insulation & casing provided including trim and controls. Trim
and controls include safety relief valve, pressure and temperature gauges, probe type low water control, and
Falcon hydronic boiler control with associated sensors.
