If you use an existing masonry chimney, it must be inspected to ensure safe condition before the stove is installed. Your local professional chimney sweep, build- ing inspector, or fire department official will be able to inspect the chimney or provide a referral to someone who can.

Intrepid II Woodburning Stove Keep the horizontal run of chimney connector as short and direct as possible, with no more than two 90° turns. Slope horizontal runs of connector upward 1/4” per foot (20mm per m) going from the stove toward the chim- ney.
The opening through the chimney wall to the flue (the “breach”) must be lined with either a ceramic or metal cylinder, called the “thimble”, which is cemented firmly in place. The fit must be snug and the joint between the thimble and the chimney wall must be cemented.

Intrepid II Woodburning Stove Fireplace Chimney Installations - Through a Fireplace If your fireplace height is at least 25” (635mm), you may install an Intrepid II with standard legs through the fireplace opening using a “positive connection” kit available from your local dealer. These positive connec- tion kits ensure a tight fit between the stove flue collar and the chimney flue.

Your local dealer or your local building inspector can provide details for other approved methods of passing a chimney connector through a combustible wall in your area. In Canada, this type of installation must conform to CAN/CSA-B365, Installation Code for Solid Fuel Burning Appliances and Equipment.

Intrepid II Woodburning Stove Floor Protection for Fireplace Installations Do not assume your fireplace hearth is completely noncombustible. Many fireplace hearths do not satisfy the “completely noncombustible” requirement because the brick or concrete in front of the fireplace opening is supported by heavy wood framing as in Figure 12.

Distance from the Center of the Flue Collar to the Wall in Top-Exit Installations The information on this page is helpful in planning stove placement for top-exiting installations, particularly those in- stallations with chimneys that pass through the ceiling. However, this is not a clearance chart. Final stove clearances must adhere to the guidelines stated in the clearance charts on Page 14.

produce soot or large flakes of char or fly ash that can coat the combustor and cause smoke to spill into the room. Coal smoke also can poison the catalyst so that it won’t operate properly. In general, the fire must be sufficiently well-established to ensure catalytic activity is initiated.

A stove is part of a system, which includes the chimney, the operator, the fuel, and the home. The other parts of the system will affect how well the stove works. When there is a good match between all the parts, the system works well.

Intrepid II Woodburning Stove Creosote Creosote is a by-product of slow wood-burning. It’s an organic tar that can condense in the flue if it’s dense in the smoke, and slow-moving, and cools off to less than 290°F. Condensed creosote is volatile, and can generate chimney fires if it gets hot enough.
Let the fire in the stove go out and allow the stove to cool completely before beginning any maintenance procedure. Care of the Cast Iron Surface An occasional dusting with a dry rag will keep the painted cast iron of your Intrepid looking new. The stove’s paint can be touched up as needed.

The Catalytic Combustion System Inspection and Cleaning This wood heater includes a catalytic combustor, which needs periodic inspection and replacement for proper operation. In the United States, it is against the law to operate this wood heater in a manner inconsistent with the operating instructions in this manual, or if the cata- lytic element is deactivated or removed.

Intrepid II Woodburning Stove • Inspect and clean the catalytic block, and vacuum out the ash at the bottom of the back plate after removing the lower fireback. Lightly clean the refrac- tory assembly that houses the element. Be careful not to damage the refractory material, which is very fragile.
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.
