FOREWORD
AERCO CFR boilers advance venting safety in the Category I boiler industry by always delivering dry flue
gas. Designed for use in any closed-loop hydronic system, the CFR promotes application flexibility. Retrofit
installations are reduced by accommodating a wide range of piping configurations, including primary-
variable systems. It can achieve an industry-best up to 3:1 turndown ratio, allowing for the reduction of
cycling losses in partial load conditions.
CFR models operate within the input and output ranges listed below.

The output of the boiler is a function of the unit
’s firing rate (valve position) and return water temperature.
When installed and operated in accordance with these instructions, the CFR 3000 complies with the
Bay
Area Air Quality Management District regulation 9, Rule 7
.
Whether used in singular or modular arrangements, CFR boilers offer maximum venting flexibility with
minimum installation space requirements. These boilers are Category I negative pressure appliances.
Single and/or multiple breeched units are capable of operation in the following vent configurations:
•
Room Combustion Air, Vertical Discharge
•
Ducted Combustion Air, Vertical Discharge
CFR boilers may be vented with Type B gas vent and require careful attention to the exhaust and
combustion air system design. Please consult the
CFR Venting and Combustion Air Design Guide,
TAG-
0105 for a list of allowable and preferred vent materials.
