SPLITTING INTERNAL MODEL HEATERS
The SP5 & SP6 Internal model heaters can be split for ease of installation. To split the heater, follow these simple
instructions:
a. Remove the heater's roof after removing the 4 roof screws.
b. Disconnect the speed sensor loom from the control board and remove it from the heat exchanger cabinet.
c. Remove the main fan motor and speed sensor loom access plate located on top of the fan cabinet
compartment by removing the single screw.
d. Unplug the main fan loom at the connection located inside the access hole which has just been uncovered.
e. Remove the 2 screws fastening the fan cabinet tabs to the heat exchanger cabinet. These are located at the
top of the fan cabinet on the heater's split line.
f. Pivot the fan cabinet upwards high enough to dislodge the lower locking tabs fixed to the fan cabinet near the
base.
g. The heater is now split in two.
h. Protect the exposed looms and tabs from damage while the heater is split in two parts.
i. Once ready, reassemble in reverse order.
Note: Ensure when reassembling the heater that everything is put back and connected correctly.

CHANGING THE RETURN AIR POP ORIENTATION
The return air pop orientation can be changed from side to side or to the rear of the heater if necessary.
Reversing the Side Entry
•
Remove the screws securing the side pop blanking plate and remove the blanking plate.
•
Swap to the other side and fasten with the same screws.
Changing to Rear Entry
Note: If this is done, predominantly when a unit is laid down, then the total number of outlets normally permitted for that installation
must be reduced by 2 (refer to the outlet register chart, Table 8 on page 26).
•
Remove the screws securing the end pop blanking plate and remove the blanking plate.
•
Swap to the open side and fasten with the same screws.
IMPORTANT:
RETURN AIR CONNECTION AT THE END OF THE UNIT (REAR ENTRY)
On applicable models, connecting the Return Air duct to the end of the unit (rear entry) will result in reduced air
flow – for example, when using a Lay Down Kit. In this situation:
– The total number of outlets normally permitted for a heating system shall be reduced by 2 (refer to the outlet
register chart located on page 20).
– DO NOT USE this configuration in Add-On Cooling applications, unless you ensure Minimum Recommended
Airflow required for the cooling is maintained.
