NOTE:

G. SECONDARY HEAT EXCHANGER INSPECTION

 

 

 

All gaskets/sealant on disassembled components or jacket panels must be replaced with new gaskets/ sealant on reassembly. Gasket and sealant kits are available from your distributor.

F.PRIMARY HEAT EXCHANGER INSPECTION

1.Turn off all power to the appliance.

2.Turn off main gas to appliance.

3.Remove the front outer jacket door.

4.Remove the front inner jacket door.

5. Check the heat exchanger surface

for

soot.

If

soot

is present, heat exchanger must

be

cleaned

and

problem corrected.

 

 

 

 

6.Remove burner as described in Burner Maintenance procedure.

7.Check “V” baffles on the exchanger. Remove and clean if necessary.

8. Remove soot

from heat exchanger with a

stiff

bristle brush.

Use a vacuum to remove loose

soot

from surfaces and inner chamber.

 

9.The heat exchanger can be removed by disconnecting all water piping to the bypass and secondary heat exchanger, removing the screws holding the heat exchanger to the top of the inner jacket. and sliding the heat exchanger towards the

front of

the

appliance.

Once

 

the

heat

exchanger

is

removed,

a garden

hose

can

be

used

to

wash

the

tubes

to

ensure

that all

soot is

removed

from

the

heat

exchanger

surfaces.

NOTE:

Do

not

wet

the insulation blankets on the

inside

of

the

outer

jacket panels.

 

 

 

 

 

 

 

 

10.Ensure that any soot present on the burner is removed. See Burner Cleaning Procedure.

11.Carefully reinstall the heat exchanger and “V” baffles if removed from the appliance.

12. Reinstall

inner

jacket

panels,

burner,

manifolds,

wires and

hoses.

Use

new

gasket

material to

ensure a proper air seal.

 

 

 

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

14.Reassemble outer jacket panels.

15.Cycle unit and check for proper operation.

FIG. 78 Location of Secondary Heat Exchanger

1.Turn off all power to the appliance.

2.Turn off main gas to appliance.

3.Break the union, pump flange and bypass valve

flange to remove the pump and external portion of the bypass assembly.

4.Remove the inner jacket door.

5.Check the heat exchanger surface for soot or

fouling.

If soot is present,

heat exchanger must

be cleaned and problem corrected.

 

6.Check “V” baffles on the exchanger. Remove and clean if necessary.

7.Remove soot from heat exchanger with a soft bristle brush. Use care not to damage coating on the exterior of the secondary heat exchanger. Use a vacuum to remove loose soot from surfaces and inner chamber.

8.The heat exchanger can be removed by disconnecting all water piping to the bypass and secondary heat exchanger and sliding the heat exchanger towards the rear of the appliance. Once

the heat exchanger is removed, a garden hose can be used to wash the tubes to ensure that all surface deposits are removed from the exterior of the heat exchanger surfaces.
