Product Usage Instructions
- Install the chimney system according to local building codes and regulations.
- Attach the rain cap (WX139 or WX139M) to the top of the chimney.
- If needed, attach the rain flange (WHM22 or WHM23) to the bottom of the chimney and secure it with the installation set.
- Connect the chimney to the stove using the installed parts.
- For the WHP1000, WHP1000M, WHP500, and WHP500M models, make sure that the insulated component is positioned correctly and that the length of the chimney does not exceed 970 mm for the insulated component.
- For all models, make sure that the chimney height does not exceed 2.0 m above the last support and that the lateral supports are spaced no more than 3.0 m apart.
- Do not install the chimney system in non-vertical installations.

General Information
The steel chimney is a CE-standardised chimney for removal of chimney gas in solid fuel run saunas and iron stoves and fireplaces using solid fuel for heating.
- Maximum nominal chimney gas temperature of the furnace joint is 600 oC.
- The cross-section of the chimney is round and the diameter 220 mm.
- The outer casing material is 0.5–0,6 mm stainless steel.
- The diameter of the smoke pipe is 115 mm and it is made out of 0.7 mm stainless steel.
- The insulation material is mineral wool.
- The maximum height of the steel chimney is five metres while the permissible maximum for the self-supporting element (e.g. the element above the roof) is two metres.
- The steel chimney can only be mounted in a vertical position.
- More detailed instructions available from the local fire authorities.

Safety Distances
It is absolutely necessary to install the chimney according to these safety distance values. Neglecting them causes a risk of fire. There shall be no inflammable materials within the established safety distances.
- The safety distance between the inflammable structures and the chimney outer casing must be minimum 100 mm. Figure 2.
- If the connecting pipe in the forward end is of non-isolated material, the safety distance from this pipe to inflammable construction materials needs to be 375 mm (WHP1500M) or 500 mm (WHP1500). Figure 2.
- The isolated chimney should be visible up to a minimum of 430 mm. Figure 2.
- When the fireplace is used a considerable heating takes place and the chimney needs to be protected with e.g. steel mesh in case it is exposed to touch. The protection, however, should not interfere with the ventilation around the pipe. There is no need for protection if the chimney is installed in a sauna.
- Do not encapsulate the chimney.
- More detailed instructions available from the local fire authorities.
Figure 2. Safety distances (all dimensions in millimeters)
Lead-Through
Openings need to be made to the intermediate floor and the roof and their minimum size is defined by the safety distances. The template printed on the utility box can be used for sizing the openings.
- In lead-through the space between the chimney and the roof structures have to be filled with lead-through insulation ZSH-200 or other class A insulating material, which has a long-term operating temperature limit of 750 °C or more.
- It is recommended to install the chimney so that the pipe joints do not meet with the lead-through areas (does not apply to the joint in WHP1500 and WHP1500M).
NOTE!
- We recommend the use of lead-through insulation ZSH-200. If other insulating material is used, it is absolutely necessary to make sure that there is no combustible material among it.
- Make sure that the 100 mm safety distance requirement is fulfilled in lead-throughs and intermediate floor.
- Prevent blowing wool etc. from entering the safety distance area. We recommend the use of lead-through protector ZSHP-712.

Connecting the Parts of the Steel Chimney
The components of the steel chimney are joined by following the instructions in the pictures (figure 4). The leading principle is to lock the smoke pipe to the former component by winding it in place, then pressing the outer casing with insulation on the smoke pipe and finally locking the casing in place with screws.
- Remove the upper end by removing the three screws.
- Pull the smoke pipe of the component/extension out of the insulation and the outer casing.
- Join the pipe by slotting it to the studs of the smoke pipe below. Turn clockwise until the joint tightens and the pipe is fixed.
- Press the outer casing with the insulation on the smoke pipe. Slot the studs in the outer casing below. Turn clockwise until the joint tightens and the pipe is fixed.
- Any gaps between the insulation sheets should be sealed by pressing them downwards in the pipe.
- Lock the outer casing in place with three self-boring screws. Bore the screws through the metal sockets.
- Join the upper end with three self-boring screws. Bore the screws through the plate.
NOTE! The upper end should be installed in a position where the screws will meet with the slot-braced outer casing.

Installation
Installing the Rain Flange
The rubber rain flange prevents water and snow entering through the chimney lead-through hole. If roofing material is profiled metal sheet or brick is used, an integral, uniform and stiffened metal sheet covering the chimney hole should be installed. This ensures the flange is fixed firmly in the damper.
- Mount the flange from the upper end of the chimney on the surface of the roof. Soap solution can be used as a lubricant if needed.
- Mould the brims of the rain flange carefully fitting it to the roof profile.
- Spread silicone underneath the flange and press the flange into place on the roof covering. Smooth out the excess silicone against the edge of the rain flange.
- Fix the flange to the damper with screws. The recommended spacing is max. 35 mm. Finally check that there are no gaps in the sealing.
- Mount the clamp from the upper end of the chimney. Place it around the head of the rain flange.
- Tighten and lock the clamp, that there is no gaps in the head of the rain flange.
NOTE! A special snow barrier is needed to pre-vent snow from sliding
against the rain flange. The amassed snow should be removed occasion-ally thus
preventing the snow accumulating and clumping on the flange.
Figure 5.
Installing the Rain Cap
Slot in the damper with the smoke pipe of the lower module. Lock the rain cap
in place by gently turning it clockwise.
NOTE! Be careful not to turn and lock the rain cap too tight! The cap
needs to be removed for chimney sweeping.
Figure 6. Installing the rain cap
Installing the Lead-Through Flange
The two-piece lead-through flange fixed in horizon-tal or pitched ceilings
trims the edges of the open-ing. The lead-through flange is best suited for
roof pitches of under 1:1.5. Figure 7.
- Install the two halves of the flange around the chimney. The straighter the roof, the more the components will overlap.
- Fix the lead-through flange in place with screws. Be careful and tighten the screws only so much as not to bend the metal sheet.
Figure 7. Installing the lead-through flange
Sweeping the Chimney
A brush made of plastic or stainless steel should be used for sweeping the chimney
