Lochinvar 1, 000 through 2 warranty Burner Cleaning Procedure, Location of Primary Heat Exchanger

Page 60

NOTE:

When the combustion air blower is removed for any reason, the inlet to the burner must be covered to prevent foreign objects from falling into the burner. A foreign object such as a nut, bolt, wire or other metallic items will cause a rapid non-warrantable failure of the burner on operation.

NOTE:

Use care when removing and handling the burner. Sharp objects or impact may damage or tear the woven burner flame surface.

Burner Cleaning Procedure

Remove any visible dust or dirt blockage from the surface of the burner with a vacuum. Compressed air may also be blown across the burner surface to clean the “pores” of the woven burner port material.

The burner may best be cleaned by immersing the burner port area in a solution of dishwashing detergent and hot water. Do not use chlorine based solvents or cleaning agents on the burner. Allow the burner to remain in the solution for a short period of time to remove dust, dirt and oil or grease laden contaminants. Rinse the burner thoroughly with clean water to remove any residue from the detergent cleaner. The burner should be air dried quickly after removal from the cleaning solution and rinsing to prevent any oxidation or rusting of the ferrous components in the burner port material.

E.CHANGING THE HOT SURFACE IGNITER

1. Turn off main electrical power to the appliance.

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

3.Carefully pull back the insulation flaps to expose the burner mounting flange.

4.Locate the Hot Surface Igniter.

5.Disconnect the two power leads to the hot surface igniter.

6.Loosen and remove the two wing nuts that mount the igniter.

7.Lift the igniter vertically out of the burner mounting flange. Use care, do not hit or break the silicon carbide igniter.

8.Check the replacement igniter for cracks or damage before installing.

9.

Ensure that the

fiber

gasket used to

seal

the

base

 

of the

igniter

to

the

burner

flange

is

reinstalled

 

to seal the base of the replacement igniter.

 

 

 

10.

Carefully

insert

the

igniter into

the

mounting

point

 

on the burner flange and position on the mounting

 

studs.

 

 

 

 

 

 

 

 

11.Reinstall the two wing nuts and tighten by hand

only. Over tightening the wing nuts may break the ceramic mounting flange.

12.Ensure that the igniter gasket is properly installed and seals the point of contact between the igniter and burner mounting flange.

13.Reconnect the power leads to the igniter.

14.Replace the insulation blanket flaps.

15.Turn on main gas supply.

16.Turn on main power.

17.Test fire the appliance to ensure proper operation.
