Section I Operation

Your WinterWarm’s Controls

and What They Do

Three controls regulate the performance of your Win- terWarm: A primary air control supplies oxygen for the fire, a damper directs air flow within the fireplace, and a variable-speed fan control, or rheostat, regulates the warm air flow into the room. (Fig. 2)

Primary Air Control

A single air control regulates the amount of heat the fire will produce and how long it will burn.

The primary air control is located above the upper left corner of the door. It is the top-most of the two brass- capped controls located there (the brass knob on the bottom regulates the fan), and is the primary source of air for starting, maintaining, and reviving the fire.

Generally, more air entering the stove makes the fire burn hotter and faster, while less air prolongs the burn.

The WinterWarm’s air supply is open to the maximum when the control lever is moved to the left, and closed when moved to the far right. It may be set anywhere between the two extremes, however, depending on the amount of heat desired.

To complement the manual setting of the air control, the WinterWarm has an internal automatic thermostat that ensures an even delivery of heat at the manual setting you select.

The Damper

The damper directs air flow within the fireplace.

The damper is operated by moving the lever located above the upper right corner of the door. It has two positions: Open, to start or revive the fire (Fig. 3); and closed (Fig. 4), for normal operation. The damper is open when the lever is to the far left, and closed when to the far right. There are no intermediate settings for damper position.

When the damper is closed, the front door automatically locks to prevent the door being inadvertently opened when the fireplace is in its catalytic mode. This could cause smoke to spill into the room.

To open the damper, lift up on the lever and move it to the far left. The lock will disengage, allowing you to open the front door.

To close the damper, move the lever to the right, continuing past the resistance to lock the damper in position. (The door handle must be positioned vertically before the lock mechanism will engage.)
