Overview

This document provides mounting and user instructions for the Lotus-Mondo Series Stoves, specifically covering models Lotus Mondo 1, Lotus Mondo 1 S, Lotus Mondo 2, and Lotus Mondo 2 S. The manual, version 2, is dated 03/02-2017.

The Lotus Wood Stove is designed for "intermittent combustion," a process that requires adherence to the provided instructions for optimal performance. These stoves are manufactured in Langeskov, Funen, Denmark, and are built according to Danish tradition, known for their reliability.

Function Description:

The Lotus-Mondo series stoves are wood-burning stoves intended for heating. They operate by burning wood in a combustion chamber, with air supply regulated to achieve efficient and clean combustion. The design incorporates smoke baffle plates to optimize the burning process. The stoves are designed to provide warmth and cosiness to a home.

Important Technical Specifications:

The manual provides specific minimum distances to combustible materials for safety. These are:

  • To side: 310 mm
  • Back: 200 mm
  • Forward: 800 mm

For non-combustible materials, a distance of 80-100 mm is recommended to allow for heat distribution and cleaning access.

Technical specifications for the different models are as follows:

  • Mondo 1: Height 96 cm, Width 48 cm, Depth 37 cm, Weight 108 kg
  • Mondo 1 S: Height 99 cm, Width 48 cm, Depth 37 cm, Weight 159 kg
  • Mondo 2: Height 96 cm, Width 48 cm, Depth 41 cm, Weight 109 kg
  • Mondo 2 S: Height 99 cm, Width 48 cm, Depth 41 cm, Weight 159 kg

Mean values from testing to DS/EN 13240 standards are:

  • Flues Gas Temperature: 359 C
  • Flue Gas Mass Flow: 4.9 g/s
  • Rate of Efficiency: 79%
  • Rated Output: 5.1 Kw
  • Flue: 12 pa

Chimney Requirements:

A good chimney draught is crucial for the stove's performance. The effective height of the chimney should typically be between 3.5 and 4.5 metres, measured from the stove top to the chimney top. The inside diameter of the chimney should be a minimum of 150 mm. All joints and connection points must be tight. The chimney should provide a draught of at least 1.2 mm water column (12 Pa), with a little more being preferable. Access to cleaning doors in the chimney is necessary. If the chimney has a register, it must have a forced aperture of at least 20 cm².

Combustion Air Supply:

Adequate air supply is essential for good and clean burning. The room where the stove is installed must have sufficient air. In some cases, an air valve in the exterior wall of the room may be required.

Floor Requirements:

The stove must be placed on a non-combustible plate (e.g., steel or stone). This plate should extend a minimum of 30 cm in front of the stove and 15 cm at each side of the fireplace opening.

Usage Features:

Kindling and Current Stoking (EN Test Procedure):

  1. The ash pan and grate must always be completely closed, even during kindling.
  2. Place approximately 2 kg of kindling wood, stacked crisscross, at the bottom of the stove. Place two fire-lighters in the middle and ignite them.
  3. Close the door ajar (approx. 3 cm aperture). Open the register under the door completely (turn left). Leave for 8-10 minutes, then close the door completely and lock the handle.
  4. Damp the register as needed during kindling.
  5. Once the fire has burned down to embers (no flames), open the door gently to avoid whirling out embers. Spread embers evenly with a poker.
  6. Add three pieces of wood (total approx. 1.7 kg). The foremost piece should have a split side facing the door and one down in the embers. Close the door immediately and completely.
  7. Open the register entirely. After about two minutes, set the register to about one-third open. The exact setting may vary with chimney draught, but flames should stabilize into a "calmly burning fire."
  8. When the wood has burned down to embers (after about an hour), repeat from step 5.

Slow Combustion:

On a proper layer of embers, add 3.0-3.5 kg of wood (3-5 pieces, not one or two large logs). Once the fire is well-caught, reduce the air supply. Always ensure clear, lasting flames. After this fire burns down, the stoking period can be extended by closing the register entirely to prevent cold air from being pulled through. Adjusting air too early or too little leads to poor efficiency and high emissions.

Wood Type and Humidity:

Birch, beech, oak, ash, elm, and fruit trees are suitable firewood. Wood should have a diameter of 7-9 cm and be a maximum of 30 cm long (25 cm used in DS testing). Crucially, wood humidity should be 15-20%. Wet wood is hard to burn, reduces chimney draught, produces a lot of smoke, and lowers efficiency as water must evaporate first, leading to high emissions and potential damage (shining soot, tar, chimney fire). Overly dry wood burns too quickly, releasing gases faster than they burn, leading to unburned gases escaping up the chimney, reducing utilization, and harming the environment. Finding the right balance requires practice.

Storage of Wood:

Wood should be stored under a roof with good airing, such as a carport or shed. Place wood on a wooden pallet or similar, off the ground. Freshly sawn and chopped wood should be left to dry for one to two years, depending on the species.

Operating Trouble:

  • Stove hard to control – burning too quickly: Check the guide. If the stove is over a year old or heavily used, packings may need replacement as heat causes them to lose tightness.
  • Stove drawing badly after installation: Verify mounting instructions. Check chimney diameter, length, tightness, and flue pipe/transition tightness. A chimney sweep may be needed if the chimney is clogged.
  • Smelling of Smoke and Soot: May be due to wind downdraught, often in specific wind directions. The chimney might be too short relative to the roof ridge, or nearby trees could cause turbulence.
  • Stove hard to make burn and may go out: Possible reasons include insufficient register opening, wet wood, poor chimney draught (clogged/leaky), or too small/cold an ember layer. Pulling out the ash pan slightly and opening the grate can provide primary air to restart the fire, then close completely. Contact a Lotus distributor or chimney sweep for persistent issues.

Maintenance Features:

Chimney Sweep:

After installation, report it to the chimney sweep for inspection and future cleaning.

Cleaning of Stove:

The stove should be cleaned regularly when cold. Remove ashes, soot, and tar residues from the pane and combustion chamber. Smoke baffle plates should be regularly dismantled to remove soot and dirt behind them. Check for free passage to the chimney. The ash pan should be emptied as needed. Ashes should be placed in a fireproof bucket before disposal, as embers can remain hot for a long time.

Stove Maintenance – Use Original Spare Parts Only:

  • Packings: These collapse in heat and lose tightness. Replace them as needed for good combustion and a clean pane.
  • Shaker Grate: May wear or crack. Lift the grate and frame a few cm, release from the draw bar, and replace. The frame itself can also be replaced as it sits loosely in the Skamol.
  • Combustion Chamber Covering: Made of vermiculite (insulation material), these panels may break or wear. Replace them when their thickness is approximately 1.5-2.0 cm. The material is porous. To prevent breakage, ensure boards are laid in the middle of the combustion chamber, not thrown. Breaking a Skamol panel does not affect its insulating effect.
  • Painting: Stains or small scratches can be covered with Senotherm spray (coke or grey). For heavy damage, grind with fine steel wool, vacuum clean, then spray. Shake the can well and spray from 15-20 cm distance. The stove must be out of operation and completely cold before painting to avoid fire risk.

Warranty:

From September 1, 2014, Lotus offers a 10-year warranty on its wood stoves, replacing the previous five-year warranty. This applies to stoves supplied after this date. The warranty covers the faultless function of the stove under normal firing conditions (ordinary chopped wood and pressed wood briquettes) and adherence to the directions for use.

The warranty does not cover:

  • Overheating damage.
  • Damage to lacquer.
  • Wearing parts and movable parts such as glass, Skamol, stones, shaker grate, smoke baffle plates, packings, slide gate, and closing gear.

The warranty lapses if the stove is not operated according to instructions or if deficiencies are remedied by an unauthorized person. It does not cover damage from inappropriate, non-expert, or incompetent use. If a product returned for warranty turns out not to be covered, the customer bears the costs. Warranty repair periods do not extend the original warranty. The warranty is valid only if duly completed and presented with the distributor's original invoice, following the invoice date.
