Keep your EWF36A Fireplace Looking New and Working Its Best

Care of the Cast Iron Surface

An occasional dusting with a dry rag will keep the painted cast iron of your EWF36A fireplace looking new.

If the paint needs retouching, first allow the surface to cool completely. Wire-brush areas needing to be painted. Touch-up with high temperature stove paint available from your local dealer. Apply the paint spar- ingly. Two light coats are better than one heavy one.

Cleaning the Glass

The EWF36A glass system requires a minimum amount of cleaning. Most carbon deposits that accumulate will burn off during hot fires.

Ash residue that accumulates on the glass should be removed periodically to prevent etching. To clean the glass, follow this procedure:

Be sure the glass is completely cool.

Cleaning with water will work in most cases. Use a glass cleaner especially made for this purpose only if deposits are especially heavy. (If heavy deposits are a frequent occurrence, however, evaluate your operating techniques.)

Rinse the glass thoroughly.

Dry the glass completely.

NOTE: The EWF36A glass is coated with a special material on the outside that helps reflect heat back into the fire chamber. Do not attempt to remove this coating.

Adjust the Door Latch Periodically

The front door of the fireplace should close securely to prevent accidental opening and should close tightly to prevent air from leaking into the fire chamber. The door handles will be positioned vertically when the door is closed.

Over a period of time, the gasket around the door will compress and the latch may need adjustment. To ad- just the handle, follow this procedure (Fig. 31):

1.Loosen the small lock nut with a wrench.

2.Extend the striker screw one turn by turning it with an Allen wrench.

3.Retighten the lock nut, while at the same time hold- ing the striker screw with the Allen wrench to prevent its turning.

Test the door seal. Close the door on a dollar bill and attempt to pull it free. If the bill is freed with little resis-

tance, the gasket isn’t snug enough at that spot. Con- tinue to make small adjustments until the setting is right.

If additional adjusting of the latch does not enable the door to seal sufficiently in one area, try “adjusting” the gasket in that area. Pack more cement or a smaller diameter gasket into the channel beneath the gasket so that the main gasket is raised and makes contact with the door frame. This procedure should solve the prob- lem. If the gasket needs replacing, follow the directions beginning on Page 23.

The Catalytic Element

This wood heater contains a catalytic combustor, which needs periodic inspection and replacement for proper operation. In the United States, it is against the law to operate this wood heater in a manner inconsistent with the operating instructions in this manual, or if the cata- lytic element is deactivated or removed.

Under normal operating conditions, the catalytic com- bustor should remain active for two to six years (de- pending on the amount of wood burned). However, it is important to monitor the combustor periodically to ensure that it is functioning properly, as well as to de- termine when it needs to be replaced. A nonfunctional combustor will result in a loss of heating efficiency, and an increase in creosote and emissions.

Inspection and Cleaning

Inspect the combustor “in place” for fly ash accumula- tion and physical damage three times per year. Do not remove the combustor unless a more detailed inspec- tion is warranted because of diminished performances as outlined in the next section.
