1.  Turn off the main electrical power to the appliance.

2.   Turn off the main manual gas shutoff to the appliance.

3.   Remove the lower outer fron access door.

4.   Disconnect the manifold(s) from the gas train using the 
 

union(s) just below each gas valve.

5.   Disconnect wiring to the hot surface igniter(s) and ground.

6.  Disconnect burner pressure line at burner.

7.  Remove the screws from the manifold mounting bracket(s) 
 

and remove the manifold(s).

8.  Remove the screws from the burner mounting flanges and 
 

slide the burner(s) out toward the front of the unit.  Use 

 

caution to prevent damage to the burners, refractory, hot 

 

surface igniter, and wiring.

9.   Remove the inner jacket panel mounting screws and slide 
 

the panel assembly out toward the front of the appliance.  

 

Use caution to prevent damage to the refractory and hot 

 surface 

igniter. 

10.   Check “V” baffles along the front and back edges of the heat 
 

exchanger (FIG. 2-5).  Remove and clean if necessary.

11.  Remove soot from the heat exchanger with a stiff bristle 
 

brush.  Use a vacuum to remove loose soot from the 

 

surfaces and inner chamber.

12. If additional cleaning is required, the heat exchanger 
 

can be removed by disconnecting all water piping to the 

 

heat exchanger, removing the screws holding the heat 

 

exchanger to the inner left side panel, and sliding the heat 

 

exchanger towards the front of the appliance.  Once the heat 

 

exchanger is removed from the appliance, a garden hose can 

 

be used to wash the tubes to ensure that all soot is removed 

 

from the heat exchanger surfaces.

Do not wet the refractory located on the 
inside of the combustion chamber.

15.  Carefully reinstall inner jacket panels, burners, manifolds, 
 

wires and hoses.  Use new gasket material to ensure a 

 

proper air seal.

16.  Reassemble all gas and water piping.  Test for gas leaks.
