WinterWarm® Small Insert Installation Installing the WinterWarm Small Insert into an existing masonry or factory-built fireplace is an effective way to add an efficient heater to your home. The existing fireplace and chimney must meet certain requirements. Requirements for Existing Fireplaces The WinterWarm Small Insert is listed for installation within a properly built masonry or heat circulating, masonry-type fireplace that is constructed in accordance with the requirements of recognized building codes.
WinterWarm® Small Insert When the insert is installed in a factory-built fireplace: • The factory-built chimney must meet type HT requirements of UL 103, ULC S629M or UL 1271988, or be re-lined from the insert to the chimney top. General Considerations / U.S. • While not required in most jurisdictions in the • • U.S., MHSC strongly recommends a full stainless steel chimney liner be installed for the insert to the chimney top to increase overall performance and reduce yearly maintenance.

WinterWarm® Small Insert That is, when using brick for the hearth extension, the brick must be a minimum of 2.6” (65mm) thick. Once you know the K factor of a given material, you can use this same formula to calculate its required thickness for approved hearth protection. The WinterWarm Small Insert has two leveling screws at the front to accomodate hearth irregularities. Optional Surround Packages B Custom-made surround panels may be made from any noncombustible material.
WinterWarm® Small Insert 3. Install the Chimney Connector Starter Pipe. (Not supplied) • Mark and drill two 5/16”, (8 mm) holes 1⁵⁄₈” (41 mm) from the lower edge of the pipe. Locate the holes on an axis that will be perpendicular to the fireplace opening when the pipe is installed. (Fig. 6) 1 6 " (35mm) 8. Join the Chimney Connector to the Flue Collar. • Assemble the draw-down hook and bar (D,E,F).
WinterWarm® Small Insert Operation Your WinterWarm Insert’s Controls and What They Do Primary Air Control Lever All WinterWarm Small Insert controls are conveniently located on the front. (Fig. 8) 2:00 High 3:00 Medium Three controls regulate the performance of your WinterWarm Small Insert: 4:00 4:30 Low The primary air control supplies oxygen for the fire. The damper directs air flow within the fireplace. The variable-speed fan control, or rheostat, regulates the warm air flow into the room.
WinterWarm® Small Insert The Fans Two fans deliver a steady stream of warm air into the room. Use the fall-away handle, (used to operate the damper), to control fan settings. (Fig. 11) The fan speed should be set at “low” when operating at low to medium burn rates. The fan speed may be set anywhere between “low” and “high” when operating at high burn rates. The control setting also depends on your particular installation’s “draft,” or the force that moves air from the stove up through the chimney.
WinterWarm® Small Insert How To Build and Sustain a Wood Fire A WinterWarm Small Insert leaves the factory with the combustor installed. In the United States, it is against the law to operate this wood heater in a manner inconsistent with operating instructions in this manual, or if the catalytic combustor is deactivated or removed.
WinterWarm® Small Insert Follow these guidelines as you start and maintain the fire, and remove the ashes. 1. Open the stove damper, and open the primary air control fully. 2. Lay some crumpled newspapers on the bottom grate. Place on the paper six or eight pieces of dry, finely-split kindling. On the kindling lay two or three larger sticks of split dry wood approximately 1-2” (25-50 mm). Do not use chemicals or fluids to start the fire.
WinterWarm® Small Insert In Fireplace Insert installations, over-sized chimneys can produce less effective results than those that are properly sized, and interior chimneys usually perform better than those located outside the house. Different results may be experienced even in the same installation if you switch from burning good, dry wood to wood that is partially rotted or inadequately seasoned.

WinterWarm® Small Insert How to Replace Gaskets Replacing the Damper Gasket Your WinterWarm Small Insert uses rope-type fiberglass gaskets to make a tight seal between some parts. With use, particularly on those parts that move, gaskets can become brittle and compressed and can begin to lose their effectiveness. These will need periodic replacement. • Lift and remove the left and right burn plates. • Two wedges hold the fireback in place. Using a All of the gaskets used are made of fiberglass.
WinterWarm® Small Insert Care of the Catalytic Combustor Your wood heater contains a catalytic combustor which should be inspected regularly and replaced periodically to ensure proper operation. It is illegal in the United States to operate this wood heater in a manner inconsistent with operating instructions in this manual, or if the catalytic element is deactivated or removed.
WinterWarm® Small Insert If replacement of the refractory package is required, proceed to #10. 10. Remove 1/4-20 x 1/2” hex head screw from the damper tab holding the damper link to the damper and let the link drop down. 11.

WinterWarm® Small Insert • Disconnect the flue liner or vent connector from the flue collar of the stove. • Slide the firechamber forward until you have access to the fireplace opening. • Inspect the flue. You can now inspect the smoke shelf area and the chimney. Before replacing the WinterWarm Small Insert, this area should be inspected for signs of deterioration and cleaned thoroughly with a chimney brush. Clean the chimney using a specially designed brush the same size and shape as the flue liner.
WinterWarm® Small Insert Appendix: Catalytic Combustor In any chemical reaction, including the combustion process, there are certain conditions which must be met before the reaction can take place. For example, a reaction may require a certain temperature, or a certain concentration of the reactants (the combustion gases and oxygen), or a certain amount of time. Catalysts, though not changed themselves during the reaction, have the ability to act at a molecular level to change these requirements.
