  • Page 4 HOMEOWNER/USER NOTE: EMERGENCY SHUT DOWN INSTRUCTIONS: Turn power off to boiler by switching the “Oil Burner Emergency Switch” (typically located at the top of basement stairway or at boiler room entrance) to the OFF position. Shut off oil supply valve. NOTICE Do not use this boiler if any part has been under water.
  • Page 5 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. Call Energy Kinetics to obtain piping and wiring instructions for applications, such as hydronic heating, radiant heating, domestic hot water, swimming pool heating, multiple boilers, primary/secondary injection loops, etc.
  • Page 6 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.
  • Page 7 RECEIVING and UNPACKING Inspect shipment upon receipt for external damage. Walk TIP: around the freight and identify and address any unusual signs of handling with the shipper before signing for the delivery. This is a fast and easy way to resolve all transportation damage claims. When unpacking and uncrating, inspect each item for internal damage.
  • Page 8 Installations should utilize the Energy Kinetics boiler stand or a suitable solid, stable, level, and smooth foundation for the boiler. If not using an Energy Kinetics supplied stand, provide a solid, level, and smooth foundation with clearance for door opening and service. Place the unit as near to the chimney or vent as possible allowing clearance for front cleaning and service as shown in Figure 1A and 1B.
  • Page 9 When connecting an Energy Kinetics Ascent Combi boiler to an existing chimney, be sure to follow all applicable local, state, and national codes that may differ from this manual, and in accordance with the following codes, as applicable: NFPA No.
  • Page 10 It is recommended that Ascent Combi and Ascent Plus Combi systems be equipped with a (optional) fuel filter and a (optional) flexible fuel line. Call Energy Kinetics to obtain optional Smart filter and optional UL Listed flexible fuel line. The flexible fuel line allows the door to open without disconnecting the fuel supply.

  • Page 12 Ascent Combi and Ascent Plus Combi Boilers are shipped from the factory with the oil burner pre-mounted. The burner flanges are designed to insert the burner head 2-3/8” into the boiler. Energy Kinetics installs a ceramic sleeve, (the amulet), to protect the burner head from the heat of combustion, and then seals the air tube flange joint with a high-grade retort cement.
  • Page 13 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 14 Supply and return connections are 1”NPT on the EK1T Ascent Combi and EK1T+ Ascent Plus Combi. 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.

  • Page 16 Figure 2D Zoning with Circulators ZONE CONTROL ZONE CONTROL BY VALVE: Heating zones controlled by zone valves will require a separate power supply for the valve(s) with end switch(s) to complete the call for heat to the Ascent Hydrostat control. A multi zone valve panel (EK P/N: 10-1216, ZVC404 or equivalent) may also be used;...
  • Page 17 ZONE CONTROL BY CIRCULATOR: Zone control by circulators requires a circulator relay with end switch (EK P/N: 10- 0464-4, SR504 or equivalent) or individual relays (EK P/N: 10-0464, SR501 or equivalent) for each zone. The boiler bypass circulator is still used in this case. NOTICE: An additional tee must be installed into the supply for each additional circulator. The tee is the supply connection for any zone circulators with the returns for these zones connected to the boiler return.
  • Page 18 Propylene Glycol in water will provide the following freeze protection: 30% down to +8F, 40% to -8F, 50% to -27F. 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.

  • Page 21 WARNING: Make All Connections with Power Off at Main Circuit Box A typical low voltage wiring diagram for the Energy Kinetics Ascent Combi and Ascent Plus Combi is shown in the “Zone Control” section of this manual. Thermostats must be located on inside walls away from cold drafts, windows or heat from fireplaces, appliances or sunlight.
  • Page 22 ADVANCED SETTINGS To improve efficiency, the EK1T Ascent Combi and the EK1T+ Ascent Plus Combi boilers have been equipped with advanced features designed to reduce idle loss (the energy required to keep the boiler in standby mode). See next section for instructions on how to set the desired Option Mode.
  • Page 23 Some advanced features are not available on the standard Hydrostat control, so the unit should be replaced with a unit from Energy Kinetics in a timely manner to ensure optimal efficiency and full boiler functionality. To temporarily install an off-the-shelf Hydrostat 3250 on the EK1T or EK1T+, follow the standard wiring diagram with the following exceptions: 1.
  • Page 24 TROUBLESHOOTING THE SAFETY PRESSURE SWITCHES The Ascent Plus Combi has three separate pressure switches to ensure safe operation in the event of several possible failure conditions. The Blocked Vent (puff) Switch measures overfire pressure to ensure the boiler maintains negative pressure and the vent system is not obstructed.
  • Page 25 HOT WATER DIAGNOSTICS First, test hot water at a simple fixture like a sink instead of a shower. Most hot water issues are corrected by the following: 1) Properly setting the mixing valve (usually between 4 and 5 ½ which is 120°F to 125°F maximum). Setting higher temperatures may cause fluctuations.
  • Page 26 Reverse flow bypassing may occur without a heating circulator check valve Mixing Valve Domestic Hot Water Supply Obstructed check valves will cause poor mixing valve temperature performance. Removal and cleaning of the integral check valve (item 4) and the valve body shuttle may be required. We recommend having a spare valve on hand as check valves may be damaged if removed.

  • Page 30 OIL BURNER OPERATION NOTICE: For reliable operation, set Air-Fuel mixture conservatively based on installation conditions. CO draft readings should be taken through the over fire test port in front jacket opening at right of burner (see FIG. 6). A 1/4" O.D. sample tube must extend at least eight (8) inches into front cover to obtain accurate readings.
  • Page 31 ANNUAL TUNE UP & INSPECTION Step 1 Initial Test (Draft Check & CO If there is an optional Silent Burner Cover, make sure it is in place before testing. 1. Remove the 1/8” brass plug from the flue box plug (1) in the top right corner of the front cover.
