ELECTRICAL CONNECTIONS
CAUTION! For Supply Connections, use wires suitable for at least 194°F (90°C).

A shaded pole motor is used to drive the Kickspace
blower on 115 -120 V. 60 hz. Since current drain is very
small, wiring codes for short circuit protection only will apply. The motor is connected in series with a normally
open aquastat in contact with the heating element. Therefore, the blower runs only when unit is sufficiently hot
and the switch is in the "min" or "max" position (not "off"). A ground screw is supplied with all units.
Electrical connections are to be made to all units following the diagrams below. Choose the diagram that best
suits your application.
Since the blower runs on all Kickspace
models only when the system circulator pumps hot water through the
unit, simply connect it to the 115 V line. The blower then starts after a short warm-up, and stops a few minutes
after the circulator shuts off (see diagram A).
Adding a line voltage type room thermostat will permit the setting of a maximum room temperature (see dia-
gram B). This 'T' stat will only operate the kickspace unit. If the circuit or system circulator is not running, the
kickspace heater will not operate.
All electrical connections must conform to local and national codes.
Connection through a circulator or zone auxiliary switch may also be used to permit instant shutdown of the
blower as the circulator stops (see diagram C).

INSTALLING KICKSPACE TYPE K & T
1. Select a location under the bottom shelf of a cabinet that meets the minimum dimensions shown in Fig. 1.
2. CUT AN ACCESS PANEL THROUGH THE BOTTOM OF THE CABINET AT THIS LOCATION, LARGE ENOUGH
FOR INSTALLATION AND SERVICE. IT IS RECOMMENDED THAT THIS ACCESS PANEL BE CONSTRUCTED SO
ANNUAL CLEANING OF THE BLOWER FAN AND COIL FINS CAN BE EASILY ACCESSIBLE.
3. At this location, center and cut an opening in the toe-space riser 4'' high x 11'' long (Model 42 see Figure 1) or
4'' high x 18'' long (Model 84 see Figure 2) or 4" high x 23" long (Model 120 see Figure 3).
4. Set the Kickspace in the space at finished floor level and check piping and wiring locations. The air outlet should
be facing but not extending beyond the toe-space riser at the opening. The air outlet should also be located at the bot-
tom portion of the 4'' toe-space riser (See Figure 1) at finished floor level. Make sure the switch is accessible through
the grille openings. The front of the unit should fit flush to the inside of the toe-space riser.
5. Install the grille over the 4'' toe-space opening with the two screws provided.
6. If using the "Easy Connect" Flexible Hose Connection Kit, see those installation instructions.
7. Next, prepare the heating element for pipe connections (this procedure will also pertain to Model types W and F).
Remove the 3 screws from the electric conn. box. Unsnap (pull) the thermostat clamp from the return copper U-bend.
Holding down the top cover, remove the 4 element cover screws. Carefully remove this top cover noting the position
of the element and the neoprene side pad. Lift out the element for soldering and fittings. Both ends are sized to accept
1/2'' solder fittings. (Note required fittings for one pipe and two pipe systems on page 4).
8. Replace the heating element in the bottom cover in the proper position. Place the neoprene side pad in position and
replace the top cover using the 4 screws. Tighten enough to keep the element in place between the covers. DO NOT
OVER-TIGHTEN!
9. Place the Kickspace
under the cabinet and connect the piping and wiring. Make sure unit & outlet are free of any
dirt or debris prior to start up. Turn on the system, purge of air, check blower operation and check for any possible
leaks in the piping (run for 2 hrs. minimum). It should then be screwed to the floor through the four resilient mounting
feet (2-inside electrical box and 2 external). Do not over-tighten screws. Secure top of electrical box.
