2.3 INTERNAL INSTALLATION 

2.3.1 Splitting the Heater

The KU model heaters can be split for ease of installation. To split the heater, follow these simple instructions.
1.  Remove the heater’s roof after removing the roof screws.
2. 

Disconnect the gas valve, overheat/pressure switch loom, igniter and flame sensor from the control board.

3. 

Disconnect the flue pipe.

4.  Remove the screws fastening the fan cabinet tabs to the heat exchanger cabinet. These are located at the 

top of the heat exchanger cabinet on the heater’s split line.

5. 

Pivot the fan cabinet upwards high enough to dislodge the lower locking tabs fixed to the fan cabinet near 

the base.

6.  The heater is now split in two.
7.  Protect the exposed looms and tabs from damage while the heater is split in two.

8. 

Once ready, reassemble in reverse order.

IMPORTANT

Ensure when reassembling the heater that everything is put back and connected correctly.
