Vermont Casting EWF30 installation instructions Fan, Glass Doors, Burn Only High-Quality Wood

The Fan

Heated air from the fireplace is forced into the room by an internal fan. The control for the fan is in the right corner of the unit.

“Off” is to the far left. (counterclockwise ) “High” is just to the right of “Off.”

“Low” is to the far right. (clockwise )

Variable adjustment of the fans is possible with any set- ting between “high” and “low.”

For best results, coordinate fan speed with the setting of the primary air control. For example, when the air control lever is set at “low,” also set the fan at “low.” With the air control set for maximum heat, set the fan at “high.”

Glass Doors

The EWF30 is intended for use with the doors fully closed or fully open only when optional spark screen is installed. (Fig. 30) NOTE: When operated with the doors open and spark screen in place, the damper MUST be in the open position.

Burn Only High-Quality Wood

The EWF30 is designed to burn natural wood only; do not burn fuels other than that for which it was designed.

You will enjoy the best results when burning wood that has been adequately air-dried. Avoid burning “green” wood that has not been properly seasoned.

The best hardwood fuels include oak, maple, beech, ash, and hickory that has been split, stacked, and air- dried outside under cover for at least one year.

For areas that do not have a supply of hardwood, com- monly burned softwoods include tamarack, yellow pine, white pine, Eastern red cedar, fir, and redwood. These too should be properly dried. Your EWF30 will accept wood up to 23” (584 mm). Longer wood pieces work better than short ones.

Wood should be stored under cover to maintain dry- ness, and should be dried at least six months for optimum heating and fire-viewing performance. Even for short-term storage, however, keep wood a safe distance from the heater and keep it out of the areas around the heater used for refueling and ash removal.

Use the Air Control Settings

that Work Best for You

No single air control setting will fit every situation. Each installation will differ depending on the quality of the fuel, the amount of heat desired, and how long you wish the fire to burn.

The control setting also depends on your particular installation’s “draft,” or the force that moves air from the fireplace up through the chimney. Draft is affected by such things as the length, type, and location of the chimney, local geography, nearby obstructions, and other factors.

Too much draft may cause excessive temperatures in the fireplace. On the other hand, too little draft can cause backpuffing into the room and/or the “plugging” of the chimney or combustor.

How do you know if your draft is excessively high or low? Symptoms of too much draft include an uncontrol- lable burn or a glowing-red part of the EWF30 front. A sign of inadequate draft is smoke leaking into the room through the fireplace or chimney connector joints, low heat, and dirty glass.

In some newer homes that are well-insulated and weather-tight, poor draft may result from insufficient air in the house. In such instances, an open window near the fireplace on the windward side of the house will provide the fresh air needed.

Another option for getting more combustion air to the fireplace is to duct air directly from the outside to the fireplace. In fact, in some areas provisions for outside combustion air are required in all new construction.

Your EWF30 is designed so that it is possible to incor- porate outside air for combustion. Directions for install- ing the optional AK-MST outside air duct is included with the kit and beginning on Page 11 of this instruction.

When first using the fireplace, keep track of the settings of the air controls. You will quickly find that a specific setting will give you a fixed amount of heat. It may take a week or two to determine the amount of heat and the length of burn you should expect from various settings.

Most installations do not require a large amount of combustion air, especially if adequate draft is available.

Do not for any reason attempt to increase the firing of your heater by altering the air control adjustment range outlined in these directions.
