    If the burner goes into lock out again, contact a qualified service agency for help. ANNUAL MAINTENANCE The Ascent Combi and Ascent Plus Combi boilers require an annual tune-up by a qualified service agency to maintain top efficiency and peak performance and to verify proper performance of all safety devices.

  • Page 7: Record Of Installation

    SCOPE This manual covers the Energy Kinetics Ascent Combi Boiler and Ascent Plus Combi boilers. These boilers are designed and equipped and have been tested to generate hot water in a low pressure closed loop system. The boiler is a major component of a closed loop system that can be used as a heat source for hydronic, radiant, domestic hot water, spa, and/or pool heating systems.

  • Page 8: Ascent And Ascent Plus Combi Boilers

    The Boiler maintains a minimum temperature (in stock configuration, see “advanced settings”) until a heating zone or zone controller (supplied by Energy Kinetics or sourced locally) signals a call for heat, or the domestic water flow switch signals hot water flow in excess of about ½ GPM. The Ascent Hydrostat control receives the call for heat or hot water and turns on the heat and/or hot water/bypass circulators, and turns on the burner if the boiler is not hot enough to satisfy the demand.

    The metal liner diameter and length should be as recommended by the metal liner manufacturer. Corrugated metal liners should be at least 5”diameter for EK1T Ascent Combi (a 6” diameter chimney liner may be required at 1.25 GPH firing rate). Energy Kinetics has 5” flexible metal chimney connectors available to be used between the boiler flue collar and the chimney.

    CAUTION: Because the energy converter removes heat from the combustion flue gas so efficiently, low firing rates may not provide high enough flue gas temperature for proper draft in a chimney with the Ascent Combi. The Columns labeled 'Chimney' and 'Sidewall' show the suitability of the firing rate for a particular combination.

  • Page 14: General Assembly

    Assembly of various packaged units is illustrated in figure 2A and 2B as well as throughout this manual. The use of non- Energy Kinetics supplied pump, controls and accessories should follow good practices. The diagrams and locations presented in the manual are recommended.

  • Page 15: Piping

    Supply and return connections are 1”NPT on Ascent boilers. Call Energy Kinetics to obtain piping and wiring instructions for alternate applications, such as hydronic heating, radiant heating, domestic hot water, swimming pool heating, multiple boilers, injection loops, etc. Figures 2C and 2D indicate general system piping arrangement and options. Piping of individual systems may vary from figures.

    EXPANSION TANK SIZING: The type and size of expansion tank depends on the total system water volume. The EK1T Ascent Combi and the EK1T+ Ascent Plus Combi contain 3 gallons of water. NOTICE: Sizing must consider cold start and hot operation due to system cold start and rapid heat up. Note: Optional trim package, EK P/N:10-1702 includes a #30 Amtrol expansion tank.

  • Page 19: Boiler Water Treatment

    When a home is winterized by draining all domestic water piping, then the Ascent Combi and Ascent Plus Combi Boilers must be protected. It is not recommended to drain the boiler, because introducing air into the boiler can cause rusting inside the boiler shell and also because the Energy Converter has a spiral water passage that cannot be completely drained of water.
