WinterWarm Fireplace Insert or System Introduction Thank you for purchasing a Vermont Castings’ WinterWarm, an efficient fireplace carefully engineered to bring you the latest in wood combustion principles and modern foundry technology.
WinterWarm Fireplace Insert or System Specifications WinterWarm *Under specific test conditions used during EPA emissions standard testing. **This value can vary depending on how the unit is operated, and the type and moisture content of the fuel used. Figure shown is based on maximum fuel consumption obtained under laboratory conditions and on average efficiencies. ***These values are based on operation in buildingcode conforming homes under typical winter climate conditions in New England.
WinterWarm Fireplace Insert or System Section I Operation Your WinterWarm’s Controls and What They Do Primary Air Control (Top Lever) Fan Speed Control (Rheostat) (Bottom Lever) Three controls regulate the performance of your WinterWarm: 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.
WinterWarm Fireplace Insert or System The Fans Two fans deliver a steady stream of warm air. Heated air from your WinterWarm is forced into the room by two internal fans. The control for the fans is below the brass primary air control knob, just above the upper left corner of the door. (Fig. 5) “Off” is to the far left. “High” is just to the right of “Off.” “Low” is to the far right. Variable adjustment of the fans is possible with any setting between “high” and “low.
WinterWarm Fireplace Insert or System Use the following air control settings as a starting point to help determine the best settings for your installation. Each is described as a fraction of the total distance the lever may be moved from right to left. WinterWarm Control Settings Burn Rate Low Medium High Primary Air Control From far right to 1/3 the distance to left From 1/3 to 2/3 the distance to left From 2/3 the distance to left to far left for kindling purposes.
WinterWarm Fireplace Insert or System Open Closed Damper Control Lever FP1074 Fig. 10 When the damper is closed, the front door automatically locks to prevent opening while a fire is burning. 1. Open the stove damper, and open the primary air control fully. 2. Lay someFP1074 crumpled newspapers on the bottom grate. Place on the paper six or eight pieces of dry, Warm finely-splitWinter kindling. On the kindling lay two or three larger sticks of split dry wood approximately 1-2” damper settings (25-51mm).
WinterWarm Fireplace Insert or System NOTE: If the charcoal bed is relatively thick and your fuel is well-seasoned, it is possible to add fresh fuel (smaller pieces first), close the door and damper, and reset the air control within five minutes. Special Tactics for Cold-Climate Heating The WinterWarm is capable of producing up to 50,000 Btu’s/hour and heating an area of up to 1,500 ft.
WinterWarm Fireplace Insert or System • Before replacing the ash pan, clear away any ash • that has spilled over the sides and back of the pan. Replace the ash pan and close the ash door and front door. Empty the ash pan regularly, typically every one to three days. The frequency will vary depending on how you operate your WinterWarm: You burn more wood at higher heat output settings, and ash will accumulate faster.
WinterWarm Fireplace Insert or System Adjust the Door Latch Periodically How to Replace Gaskets The front door of the WinterWarm should close securely to prevent accidental opening and should close tightly to prevent air from leaking into the fire chamber. The door handle will be positioned vertically when the door is closed. Your WinterWarm uses rope-type fiberglass gaskets to make a tight seal between some parts.

WinterWarm Fireplace Insert or System Adjust the Damper as Needed Examine your WinterWarm’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. Both fine and coarse adjustments to the damper are possible. Begin with the fine adjustment, which modifies the pressure on the damper plate directly; it will take care of most sealing problems.
WinterWarm Fireplace Insert or System When to Suspect a Combustor Problem The best way to evaluate the performance of your WinterWarm’s combustor is to observe the amount of smoke leaving the chimney — both when the combustor has achieved “light-off” and when it has not. Follow this simple two-step procedure: • With a fire going and the combustor properly acti- 4. Tip the lower fireback forward, and remove it by lifting it up and toward you. 5. Carefully remove the access panel. (Fig.
WinterWarm Fireplace Insert or System • Check the combustor and the bottom of the refractory chamber for a build-up of fly ash, and remove any ash by taking the combustor outside and gently blowing air through the element. Do not brush the surface, as this could damage the element. Carefully vacuum ash from the refractory chamber. • Refer to the “Catalytic Combustor Appendix” on Page 37 for information on what kinds of damage or deterioration to look for.
WinterWarm Fireplace Insert or System You should inspect the system every two weeks during the heating season as part of a regular maintenance schedule. To inspect the chimney, let the WinterWarm cool completely. Then, using a strong light, sight up through the flue collar into the chimney flue. If it is not possible to inspect the flue system in this fashion, the firechamber must be removed to provide better viewing access.

WinterWarm Fireplace Insert or System Electrical Requirements The WinterWarm Cabinet has a removable junction box located on the bottom front corner of the left side. This enables the wiring to be completed before the cabinet is installed if desired. The junction box houses two receptacles, one for the WinterWarm column fans and the other for the optional cabinet blower.
