Rev. B 4-16-02 3 P/N 472091
C. WIRING
1. Look at the existing wiring diagram on the left door and find out what model of the NT heater you have from top
of wiring diagram.
NOTE
First check the three terminals on your blower. If there are male terminals, please cut them and replace with
female terminals, (provided in the kit).
•If you see “MiniMax NT 400 Low NOx” that means your heater is Single Voltage
Dual Speed (SVDS): Replace the new wiring diagram for SVDS. The label is provided in
the kit, (P/N 472084).
• Please see Figure 2 for SVDS and follow the instructions below exactly.
a. Reconnect existing wire P7 to J7, P9 to J9, and P10 to J10 respectively on the 6800 control board.
b. Reconnect the existing white wire from Low Gas Pressure Switch to “TH” on the Ignition Module.
c. Reconnect the existing 5-pin Mate-N-Lok Plug (with gray, black, white and blue wires) to Ignition Module.
The male terminals of gray and blue wire connect to Hot Surface Igniter (HIS #1).
d. Connect new wire #P11 to J11. Then, connect the common female terminal, orange wire, to “IND” on the
Ignition Module; next, connect the common female terminal, (red/blue) wire, to “VAL” on the Ignition Module.
e. Connect existing wire P4 to J4 but using “splice” to connect new wire #1 (orange). The female terminal connect
to “24VAC” on Ignition Module.
f. Connect new wire #2 (white). The common male terminal connect to white wire of P11; the 1st female terminal
connect to “GND” on the Ignition Module; the 2nd female terminal connect to “RET” on the Fan Board.
g. Connect new wire #3 (white). The common male terminal connect to white wire of the Blower; the female
terminal connect to F1 terminal of Ignition Module; the other female terminal connect to Hot Surface Igniter (HIS #2).
h. Connect new wire #4 (orange). The common female terminal connect to “24 VAC” on the Fan Board; the
female terminal connect to “PC” on the Fan Board; the male terminal connect to orange wire of P11.
i. Connect the new wires #5 (white), from F2 of Ignition Module to Terminal Block #4.
j. Install the In-Line Fuse (provided in the kit) between the Hot Surface Ignitor (HSI #2) and the blower, see Wiring
Diagram (Figure 2).
•If you see “MiniMax NT 250 Low NOx” that means your heater is Single Voltage
Single Speed (SVSS): Replace the new wiring diagram for SVSS. The label is provided in
the kit, (P/N 472088).
• Please see Figure 3 for SVSS and follow the instructions below exactly.
a. Reconnect existing wire P7 to J7, P9 to J9, and P10 to J10 respectively on the 6800 control board.
b. Reconnect the existing white wire from Low Gas Pressure Switch to “TH” on the Ignition Module.
c Reconnect the existing 5-pin Mate-N-Lok Plug (with gray, black, white and blue wires) to Ignition Module.
The male terminals of gray and blue wire connect to Hot Surface Igniter.
d. Connect new wire #P11 to J11. Then, connect the common female terminal (orange) wire to the Air Pressure
Switch; then connect the female terminal (orange) wire to the “IND” on the Ignition Module; next, connect the
common female terminal (red/blue) wire to “VAL” on the Ignition Module; last, connect the female terminal
(white) wire to “GND” on the Ignition Module.
e. Connect existing wire P4 to J4 but using “splice” to connect new wire #1 (orange). The female terminal connect
to “24VAC” on Ignition Module.
f. Connect the new wires #5 (white) from F2 of Ignition Module to Terminal Block #4.

Knob Stopper
Screw A
D. OPERATION
Dual Temperature Control System
For convenience and economy all MiniMax NT heaters are
equipped with two thermostats on the front of the heater
control panel; see Figure 1.
THERMOSTAT KNOB STOPPER
Each thermostat is equipped with a mechanical stop that can be
locked or unlocked with use of a screwdriver to prevent
temperatures in excess of that desired by the user; see Figure 4.
The maximum setting can be adjusted by loosening the screw "A"
and turning the stopper dial to desired maximum setting. Lock the
setting by tightening the screw. The Mechanical stop is under the
knob. Ensure that the knob is stopping at the correct position when
the knob is rotated clockwise from a lower temperature position.
(See Thermostat Adjustment.)
NOTE
To eliminate error due to piping heat losses,
measure pool temperature with an accurate
thermometer directly at the pool or spa.
THERMOSTAT ADJUSTMENT
The knob with locking feature eliminates the need for constant
thermostat adjustments. Set the knob pointer to the desired pool
or spa temperature.
If further adjustment is needed, rotate the knob until the desired
temperature is obtained. This knob position corresponding to
your desired maximum pool or spa temperature may now be
preset (locked) by the knob stopper which prevents the knob
from being turned beyond the maximum temperature you set.
Figure 4.
INDICATOR LIGHT DESCRIPTION
The MiniMax Pool Heater provides nine status indicator lights, six can be seen from the front of the control panel which help you
understand the operation of the heater. If something should go wrong, the lights will aid in troubleshooting the problem. Three
additional lights can be seen after opening the control panel. These three lights give the service technician advanced troubleshooting
capability. All the LED lights are green with the exception of the red service LED.
POWER LIGHT (POWER)
The light is on at all times, in any switch position, indicating 24
VAC power is being supplied to the control circuit. If it fails to
light, no other light will be on. Possible causes are: a) external
power to the heater is disconnected, check service panel circuit
breaker or fuses; b) local circuit breaker inside the transformer
has tripped -- investigate cause before resetting; c) transformer
has failed.
THERMOSTAT (TSTAT)
This light is on when the thermostat contacts close, signaled by
the water temperature falling below the setpoint, calling for the
heater to fire to maintain the desired water temperature.
AUXILIARY (AUX)
This light is on when it indicates the remote switch contacts are
closed. This allows you to observe if your remote switch is
properly closing the heater control circuit. When shipped from
the factory a jumper is installed to maintain closed circuit in the
absence of a remote switch.
PRESSURE (PRESS)
This light is on when Spa/Pool Selector switch is on, indicates
the circulation pump is running properly. If pressure light fails
to light, the pump may have lost its prime or water flow may be
restricted by an inadvertently closed valve or clogged filter or
pump basket. If you have determined that there is no water
flow restriction to the heater, you should call a qualified
serviceman.
POWER (THERMOSTAT SELECT) SWITCH
The Pool/Off/Spa switch allows the heater to be turned off
when heating is not desired.
1. “Pool” position - Maintains selected pool temperature.
2. “Off” position - Heater will not come on regardless
of drop in pool or spa temperature.
3. “Spa” position - This allows separate control of spa
water temperature.
Rev. B 4-16-02 7 P/N 472091
HEAT (HEAT)
The heat light is on any time the thermostat has signaled a
call for heat which initializes the ignition safety firing circuit -
- the light comes on to indicate successful firing of the main
burners.
SERVICE (SERVICE)
The service light is off during normal operation of heater.
The light only comes on if a problem with a control has
occurred or when the heater is first firing. The problem must
be investigated by the serviceman prior to attempts to fire
the heater again.
The diagrams that follow give examples of troubleshooting a malfunctioning heater using the assistance of the indicator lights.

F. RAIN PROTECTION
NOTE
Please ignore the following steps in Section F if the heater has been installed with a rain protection shield.
1. Using the silicon tube (provided in the kit) to seal the 3 sides of the edge. See Figure 5.
WARNING
The edges of the heater door can be sharp. Handle heater door with care when trimming the plastic studs. Failure
to do so could result in lacerations from the heater door.
2. Using a knife, slightly trim the plastic stud, (if required), and push it through the plastic barrier. Then insert the
pushnuts, included in the kit, onto the plastic stud in order to hold the plastic barrier, (see Figure 5).
SEAL THESE 3 SIDES WITH SILICON
TRIM THE STUD FIRST, THEN HOLD THE SHIELD
BY PUSHING THE NUT THROUGH THE STUD.
