Accel CS Boiler - Gas Heat - Eighth Edition – January, 2015 34
BOILER WATER TREATMENT
Addition of boiler water treatment is recommended to reduce scale buildup inside the boiler. Energy Kinetics
recommends addition of one quart of 8-Way Boiler Treatment per 30 gallons system water. 8-Way Boiler Treatment is
recommended for all installations and will help dissolve scale buildup due to hardness in the boiler water. Call Energy
Kinetics for more details about boiler water treatment and about hard water conditions.
Thoroughly cleaning and flushing the boiler and piping after installation is highly recommended.
WINTERIZING
ANTIFREEZE
Only antifreeze rated as non-toxic (such as propylene glycol) should be used if adding antifreeze. Hard water should not
be used in combination with generic antifreeze. Energy Kinetics supplies a quality inhibited propylene glycol anti-freeze
with orange dye and an antifoam agent. 8-Way Boiler Treatment can be added to Energy Kinetics antifreeze and is
recommended in areas of hard water.
NOTICE: Thoroughly clean system prior to adding antifreeze.
Tri-Sodium Phosphate (TSP) is recommended for removing flux and other oil based compounds. Once system has been
cleaned and flushed, add antifreeze to obtain approximately a 30% by volume mixture of antifreeze in water. Call Energy
Kinetics for assistance in calculating how much anti-freeze to add to system.
NOTICE: If the Accel CS boiler may be exposed to freezing temperatures, such as a vacation home shut down for the
winter, then anti-freeze should be added to the boiler water.
NOTICE: If the Accel CS boiler may be exposed to freezing temperatures, such as a vacation home shut down for the
winter, then the condensate collection system, including the condensate trap, condensate neutralizer,
condensate pump, and all condensate piping should be either filled with antifreeze or removed and drained.
The condensate collection system must be reassembled prior to placing the boiler back into service.
When a home is winterized by draining all domestic water piping, then the boiler must be protected. When draining the
domestic water piping system, be sure to drain the domestic side of the plate heat exchanger. If the hydronic system will
not be drained, then add enough anti-freeze to protect the entire hydronic system including the boiler, piping, radiation,
circulators, etc. Propylene Glycol in water will provide the following freeze protection: 30% down to +8° F, 40% to -8° F,
50% to -27° F. Energy Kinetics recommends using 30% anti-freeze to obtain the best boiler performance. Use over 30%
anti-freeze only if lower temperature freeze protection is mandatory.
WIRING AND CONTROLS
The Accel CS boiler is furnished with controls and basic accessories as illustrated and described in this manual.
DANGER: All wiring installations in the United States must comply with the NEC, and any local codes. All wiring
installations in Canada must be in accordance with the Canadian Electric Code, Part I.
LINE VOLTAGE – ELECTRICAL CONNECTIONS
The Accel CS boiler operates on 120 VAC, 60 Hz power. The boiler is rated to operate with supply voltages anywhere
between 102 VAC minimum and 132 VAC maximum.
Boiler power rating: 120 VOLT 60 HZ, less than 12 Amperes.
Branch circuit overcurrent device rating: 120 VOLT 60 HZ, 15 Amperes.
Central heating equipment such as the Accel CS boiler must be connected to an individual branch circuit. The individual
branch circuit for the Accel CS boiler must be a dedicated 15 AMP fused circuit. The branch circuit overcurrent device is
also the main power disconnect for the Accel CS boiler. Turn off the branch circuit at the main service entrance panel
before making connections to the Accel CS boiler. The branch circuit wiring must be properly sized for the branch circuit
rating.
DANGER: Make All Connections with Power Disconnect Turned Off at Main Service Entrance Panel.
If required by local codes or the authority having jurisdiction, install a system disconnect switch (in some parts of the
country, this is known as ‘the red emergency switch’) that will disconnect the power to the Accel CS boiler.
Pigtails inside the Accel CS cabinet are provided for the line voltage power connection. Refer to the wiring diagrams
shown later in this manual for location. Connect black pigtail to hot, white pigtail to neutral and the green pigtail to ground.
