GENERAL ASSEMBLY
Assembly of various packaged units is illustrated 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.
WARNING:
Boiler shall be installed such that the gas ignition system components are protected from water (dripping,
spraying, rain, etc.) during appliance operation and service (circulator replacement, control replacement, etc.).
BOILER MOUNTING
The boiler comes on a factory mounted base. Place the boiler with the base on the floor. If desired, place patio blocks
on the floor first, then place the boiler on the patio blocks.
BOILER PITCH:
The Resolute pressure vessel is manufactured level with the base. The top cover of the boiler is
pitched with the back higher. The base has adjustable feet, allowing the base to be leveled.
PIPING
All piping and accessory connections should follow good practice using approved joint sealants. Figure 2A
indicates a
general system piping arrangement and options.
Piping of individual systems may vary from Figures. Supply and return
connections are 1”NPT on the EK1. Contact Energy Kinetics for additional piping schematics.
WARNING:
A low water cut-off must be field installed if the boiler is installed above radiation level or if required by the
authority having jurisdiction. A low water cut-off is available from Energy Kinetics as an option.
PIPING SO THE DOOR CAN OPEN:
to avoid conflicts with the door opening, do not run piping in front of the boiler.
The door opens and drops down to the front of the boiler. The burner and air box also need clearance when the door
opens. Do not locate any piping in front of the boiler unless clearance from the door is verified. This also applies to the
combustion air piping.
NOTICE:
Disconnect the air inlet pipe before opening the front door.
