† Spare tapping screws are provided in the product package for your convenience.
† All 14 M10 bolts (3 in) of the extension kit will be used for the NFC series when installed in combination with the NPE, NCB, and NFB series.
Other congurations will have one bolt left over.
† The 5x12 tapping screws without washers are only used for installing the NPN series.
* A single kit can be used to mount up to 2 water heater or boiler units. When mounting 2 units, the back-to-back conguration can be used.
** An extension kit is used to add more water heater or boiler units to the frame.
*** These kits can be installed both indoors and outdoors.
Note Although the oor mounting hardware is not included with this kit, you must x the Ready-Link-Rack securely to the oor to
complete installation. Use appropriate anchor bolts (3/8 in) to x the frame to the ground.

Attaching an extension kit
Refer to the instructions on pages 5 to 8 to connect an
additional extension rack to the single frame with the xed
brackets and M10 bolts (3 in).

is removed, rust may develop and possibly aect the
lifespan of the rack. Recoat any areas where the coating is
removed or scratched.
Attaching a water heater or boiler to the frame

Place a xed bar between the middle of the
2 post bars and 4 xed brackets (middle) with
6 M10 bolts (3 in) to attach the middle bar.
Note
Depending on the boiler or water heater

●NPE/NCB/
NFB series
●NFC series
Fixing the frame to the location
1. Ensure that all screws and bolts are tightened securely.
2. Fix the frame to the ground with appropriate anchor bolts.
WARNING
●Ensure that the oor is at and strong enough to support the
water heater or boiler and frame when all preparations for
operation are complete.
●Ensure that the frame is xed securely as property damage,
personal injury, or death may result if the frame falls.
Note Although the oor mounting hardware is not included with this kit, you must x the Ready-Link-Rack securely to the oor
to complete installation. Use appropriate anchor bolts (3/8 in) to x the frame to the ground. Before xing the frame to the
ground using anchor bolts, ensure that the anchor bolts protrude above the surface of the ground by at least 2 in (50 mm).
Assembling the upper bar
NPN Series
B

water heater can hang on the screw.
3. Back-to-back Option: Repeat step 2 on the
rear side of the xed bar.
Back-to-back
Option
