Operating instructions

Initial lighting and daily use

Jøtul F 400 is a clean-burning product and with additional supplies of combustion air, it allows for afterburning of hazardous gases and particles. It is important that the system is used correctly.

The stove is equipped with certain functions that are described in the chapter: Control of functions.

ENGLISH

Note! Danger of overheating: The stove must never be used in a manner that causes overheating.

Overheating is defined as overfilling the stove with firewood and/or leaving the draught vent fully open.

The chimney draught should never exceed 2,5 mmVs (25 Pa). A sure sign of overheating is when parts of the stove glows red. When this happens, reduce the draught vent opening immediately.

Warning! Each fire should burn down to embers before new firewood is added.

Initial lighting

Open the draught vent fully by pushing the vent all the way to the right (fig. 3-A). Put in some crumpled newspaper, kindling wood and firewood and start a small fire. Add more firewood gradually and let the fire burn briskly for a couple of hours. Let the fire die out and repeat one more time.

Note! Odors when using the stove for the first time. Painted products. The stove may emit an irritating gas when used for the first time, and it may smell a little. The gas is not toxic, but it is recommended to open a window or a door to provide additional ventilation in the room. Let the fire burn with a high draught until all traces of gas have disappeared and no smoke or smells can be detected.

Enamelled products: Condensation may form on the surface of the stove the first few times it is used. This must be wiped off to prevent permanent stains forming when the surface heats up.

Daily use

Fire up with the aid of newspapers and some kindling wood. Place two medium sized logs in/out on each side of the base. Crumple some newspaper (or birch bark) between these and add some kindling wood in a criss-cross pattern on top and light the newspaper. Increase the size of the logs gradually.

Draught vent (fig. 3- A). Regulate when the wood is properly lit and burns well. Check that the afterburning (secondary combustion) starts.This is best indicated by yellow, flickering flames in the air chamber. Then regulate the rate of combustion to the desired level of heating by adjusting the draught vent.

Always use good quality firewood. It gives the best results and doesn’t damage the product.

Never burn the following materials in the stove:

-household waste, plastic bags etc.

-painted or impregnated wood (highly toxic)

-chipboard or laminated boards

-driftwood

This may harm the product and pollute the atmosphere.

Note! Never use flammable liquids such as petrol, kerosene, red spirit or similar to start the fire. This may cause harm to both yourself and the product.

Maintenance

Cleaning the glass

Jøtul F 400 is equipped with an air wash system. Through the draught vent air is sucked in above the fireplace and washed down along the inside of the glass. This system has the advantage that it provides better combustion and reduces the buildup of soot deposits on the glass.

Still, some soot will always stick to the glass, but the quantity will depend on the local draught conditions and adjustment of the draught vent. Most of the soot layer will normally be burned off when the draught vent is opened all the way and a fire is burning briskly in the fireplace.

Good advice! For normal cleaning, moisten a paper towel with warm water and add some ash from the burn chamber. Rub it over the glass and then clean the glass with clean water. If it is necessary to clean the glass more thoroughly, a glass cleaner is recommended (follow the instructions for use on the bottle).

Ash removal

Jøtul F 400 has an ash pan which makes it easy to remove the ash. Scrape the ash through the grate in the base plate and into the ash pan. Use something like a glove to grab the handle on the ash pan and take away the ash. Make sure that the ash pan doesn’t fill up so high that it keeps ash from coming through the grate into the pan.

Make sure the door to the ash pan is securely shut when the stove is in use.

Also see the description of how to handle ashes under:

Measures to prevent fires.

Cleaning and soot removal

Soot deposits may build up on the internal surfaces of the stove during use. Soot is a good insulator and will therefore reduce the stove’s heat output.

An annual internal cleaning is necessary to get the best heating effect from the product. It is a good idea to do this in connection with the sweeping of the chimney and flue pipes.
