Accel CS Boiler - Gas Heat - Eighth Edition – January, 2015 31
The flange at the top, rear panel of the boiler must be hooked into the two notches with the taper lead in.
The two brackets must be installed level and vertically in line with each other per the dimensions given.
The lower bracket should be mounted at least 12” from the bottom of the bracket to the surface below it. This provides
clearance for the gas piping, condensate trap, neutralizer and condensate pump.
The top of the top mounting bracket must be located a minimum of 20” from the ceiling to allow clearance for service and
cleaning of the pressure vessel.
Lift and place boiler on wall mounting brackets
WARNING: The boiler is heavy and requires two people to lift and place on bracket. It is recommended that leather
gloves are worn while lifting into place to prevent the possibility of cuts from the edges of the sheet metal
chassis.
The boiler should only be lifted from the bottom and back of the enclosure. Front covers may be left on. Do not try to lift
by the piping or any other system components.
With help from a second person, lift the boiler up and hook the rear top edge of the boiler into the notches on the top wall
mounting bracket. If required, slide the boiler left or right to center it over the mounting brackets.
HYDRONIC PIPING
NOTICE: To avoid conflicts with the opening of the system, piping should be behind, beside, beneath, and/or above the
boiler. With the upper and lower front covers removed, the center panel swings down for internal access. The burner also
needs clearance when top cover is removed. Do not locate any piping in front of the boiler or over top of the pressure
vessel until clearance from the center panel and turbulator removal is verified. This also applies to the gas line piping.
All piping and accessory connections should follow good practice using approved joint sealants. The following pages
include several general system piping arrangements and options. Piping of individual systems will vary from the suggested
arrangements at the discretion of the installer.
Supply and return connections on Accel CS boiler models are:

NPT
EK1C 1”
EK2C 1-1/4”
EK3C 1-1/2”
Call Energy Kinetics to obtain piping and wiring instructions for alternate applications, such as radiant heating, domestic
hot water, swimming pool heating, multiple boilers, injection loops, etc.
Use Energy Kinetics Smart Thread Sealant P/N 10-0620, or equal.
ZONE CONTROL
ZONE CONTROL BY ZONE VALVE: The Accel CS boiler is designed to provide multi-zone control of the heating system.
Energy Kinetics recommends and offers two wire and four wire, full port, 24-volt zone valves for control of each heating
zone. Refer to Zone Piping diagrams in the Drawings section of the manual.
ZONE CONTROL BY ZONE CIRCULATOR: Zone control by circulators requires a flow valve, circulator and 24-volt relay
(fan type such as Honeywell R8225B or RIB relay or Energy Kinetics relay box kit) for each zone. The main circulator and
domestic heat exchanger are still used in these cases. Refer to Zone Piping diagrams in the Drawings section of the
manual.
NOTICE: An additional tee(s) must be installed into the supply on the inlet side of the main circulator. This tee is the
supply for circulators with returns for these zones into normal return location.
ZONE PURGING: Valves to isolate and purge individual zones should be installed according to good piping practices.
EXPANSION TANK SIZING: The type and size of expansion tank depends on the total system water volume and
temperature.
NOTICE: Sizing of the boiler expansion tank must follow expansion tank manufacturer’s guidelines.
NOTICE: Always use an isolating heat exchanger to heat a pool, spa or domestic water.
