Tools required: Phillips Head Screwdriver.

Removing the Air Intake Chamber Box:
1.  Set the gas control valve/thermostat to its lowest 

setting by pressing the “COOLER” and “HOTTER” 

buttons together at the same time holding for 1 

second. Then press the “COOLER” button to the 

lowest setting (Figure 74).

2.  Turn gas control switch  to the “OFF” position 

(located right side of the gas control valve/

thermostat) and turn off the gas supply to the unit 

(Figure 75). 

3.  Disconnect the electric connection by unplugging 

the transformer from the wall outlet (Figure 75).

4.  Remove the manifold cover/ outer door from the 

unit by depressing on the lower portion and pulling 

outward.

5.  Remove the air pressure tubing from the air 

pressure switch by pulling downward on the 

tubing at the connection to the air pressure switch 

(Figure 76).

6.  Using a phillips head screwdriver, remove the 4 

screws securing the air intake chamber box to the 

water heater’s side (Note: keep these screws in a 

safe place for reinstallation later) (Figure 77).

7.  Rotate the top of the air intake chamber box from 

left to right (only a few inches in both directions) 

while pulling outward at the bottom removing 

the air intake chamber box from the combustion
