Accel CS Boiler - Gas Heat - Eighth Edition – January, 2015 6
Accel CS BOILER
IMPORTANT MESSAGE TO HOMEOWNER: These instructions should be carefully read and kept for future reference to
gain the best performance from your Accel CS boiler.
CONGRATULATIONS ON YOUR PURCHASE OF THE Accel CS BOILER with its highly efficient condensing low mass
hydronic heat exchanger, modulating burner and state of the art zone and domestic hot water control. It is the product of
years of engineering and advanced design, which brings together in a single system all elements needed to provide
efficient home heat. This operation and maintenance information has been prepared so that you may better understand
and use your Energy Kinetics Accel CS boiler and Heating System.
The Accel CS Boiler basically consists of a heat source (gas burner with control), an energy converter, piping, sheet
metal chassis and outer covers. For a typical residence, the installation may include a circulating water pump and up to five
zones controlled by the electronic Condensing Heat and Hot Water Hybrid Energy Recovery Control (Condensing Energy
Manager). For a typical multi-boiler light commercial situation, the installation may include a multi-boiler control along with
the appropriate primary/secondary piping. To support both types of installations, Energy Kinetics provides suggested piping
and wiring schematic drawings, which will be provided upon request. For any questions about installations not already
explained within this manual, consult Energy Kinetics Tech Support at 800-323-2066.
Accel CS BOILER - PRINCIPLE of OPERATION
The Boiler remains cold until a thermostat calls for heat. The Condensing Energy Manager receives the call for heat and
opens the respective heat or hot water zone, turns on the main circulator and burner. When the thermostats are satisfied,
the Condensing Energy Manager turns off the burner and enters the energy recovery stage. The circulator and zone (zone
valve or zone circulator) stay energized to deliver the heat remaining in the boiler to your home.
When energy recovery is complete and the Boiler has cooled off, the Condensing Energy Manager turns off the system
and waits for another thermostat (or tank thermostat) to call for heat. The Accel CS runs the burner only when you need
heat and delivers that heat only where you need heat.
The Accel CS Energy Converter is the product of advanced thermal engineering. It is designed with thirty seven fire
tubes, optimized to produce the maximum condensation with water side baffles to direct hydronic water flow and improve
heat transfer. This is a “forced circulation counter-flow” design that provides very efficient transfer of heat from the burning
fuel to the circulating water. The superior insulation of the boiler minimizes heat losses to the surroundings, resulting in
directing heat to your home in an efficient and quiet manner.
The Accel CS has an extremely high annual efficiency (over 99% of steady state) because it runs only when your home
needs heat. Energy recovery is completed at the end of each heat call, virtually eliminating off cycle losses.
Your Accel CS holds a small volume of water and it begins to supply heat very quickly. Maximizing condensing operation
by operating with lower boiler temperatures during warmer outdoor weather can cause longer and slower responses to
thermostat calls. The innovative SmartBoost™ function accelerates the response to recovery from thermostat night
setbacks for enhanced comfort and savings. Depending on the model, the Accel CS can heat water with input rates of up
to 399,000 BTU’s per hour.
The Accel CS boiler is designed with a removable burner flange and condensate collector that allows access to the inside
of the boiler for inspection and cleaning. All access for service is from the front, top, and bottom and the Accel CS boiler
may be floor mounted on a stand, or may be optionally mounted on a wall.
