Adjust the Damper as Needed

Examine your WinterWarm Small Insert’s damper after the first 50 hours of use and adjust it if necessary. Thereafter, check the damper at least once a year and adjust as needed.

To inspect how well the damper seals, first make sure the fire is out and the WinterWarm Small Insert is cool. Open the front door, and close and lock the damper.

Inspect how the damper plate seals against the damper frame. (Fig. 15)

There should be no gaps in the gasket and the damper should be tight against the frame. If a section of gasket is missing, replace the gasket. Instructions for gasket replacement are given later in this section. If the gasket appears to be in good condition, continue by pushing gently on the damper. There should be some give but no rattle. If adjustment is necessary, proceed as fol- lows:

1.Remove the Mantel piece.

2.With the Damper Control Lever in the open posi- tion (to the right), loosen the retaining screw on the Damper Latch by turning it counterclockwise. (Fig. 15

3.Move the latch approximately 1/16” to the left, and tighten the screw.

4.Examine the upright tab that holds the damper rod in place. If the screw is loose, tighten it. If the tab is bent, replace it.

5.Close and lock the damper, and check for gap and rattle. Repeat the procedure if necessary.

If the problem is still not solved, replace the damper gasket. Instructions are on Page 16.

IMPORTANT NOTES

•Do not operate the WinterWarm Small Insert if the glass is damaged or broken.

•The glass used in your WinterWarm Small Insert is coated with a special material on one side that reflects heat back into the fire chamber. To re- place new glass correctly, look along the edge of the glass for a printed notice that reads, “THIS SIDE OUT”. Be sure to install the glass with the notice side out.

•Replace glass only with CFM Corporation high temperature ceramic glass, available from your Vermont Castings’ Authorized Dealer.

Removing and Replacing Door Glass

Follow this procedure to replace glass.

•Open the door and loosen the four retaining clip screws that hold the glass to the door. Swing the clips out of the way. Tilt the glass away from the door frame and lift up. (Fig. 16) Wear gloves and use cau- tion when handling broken glass.

•Examine the gasket that seals the glass to the door frame. Replace if necessary with gasket obtained from your local Vermont Castings’ Authorized Dealer. Directions for replacing gaskets are given below.

•Check the channel at the bottom of the door frame, and clear away debris if necessary.

•Carefully place the new glass in the door frame.

•Secure the clips, being careful not to over-tighten. Be sure the glass is firmly seated against the gasket. Close the door gently to confirm the clips have been properly positioned. It is possible for the glass to be damaged if the clips have been installed incorrectly and the door is closed with force.
