2 Maintenance

Inspect and clean the heat exchanger

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.

NOTICE

Do not wet the refractory located on the

 

inside of the combustion chamber.

Review with owner

1.Review the User’s Information Manual with the owner.

2.Emphasize the need to perform the maintenance schedule specified in the User’s Information Manual (and in this manual as well).

3.Remind the owner of the need to call a licensed contractor should the appliance or system exhibit any unusual behavior.

4.Remind the owner to follow the proper shutdown procedure and to schedule an annual start-up at the beginning of the next heating season.

Oiled bearing circulators

Inspect the pump every six (6) months and oil as necessary. Use SAE 30 non-detergent oil or lubricant specified by the pump manufacturer.

13.Ensure that all burner ports are cleaned to remove any soot (reference this section).

14.Carefully reinstall the heat exchanger, “V” baffles, and frame runners if removed from the appliance.

NOTICE

Make sure the frame runners seal securely where they contact the front and rear compartment refractory.

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.

17.Reassemble outer jacket panels.

18.Cycle the appliance and check for proper operation.
