SEISMIC RESTRAINTS MERIDIAN BASE INSTALLATION

Place the appliance on top of the meridian base. Make sure to align the front and side edges of the appliance to the meridian base.| Use the supplied bolts and washers, then tighten, this will hold the appliance in place.

Position the appliance and meridian base assembly to the desired position. Make sure the flue hole is in the desired position. Use the existing holes at the bottom of the meridian base to drill the holes for m8-m10 dyna bolts.| Use the preferred Dyna bolt size and affix the appliance and meridian base assembly to the floor. When both dyna bolts are tightened the installation is complete.

SEISMIC RESTRAINTS TABLE INSTALLATION

Place the back of the appliance to the back edge of the cube table. Make sure the appliance is centered from the left and right.| Remove the fan box and back assembly by moving it towards the top. The assembly only needs to move by approximately 10-15mm. Then pull the back assembly away from the appliance. Unplug any electrical connectors or wires.

Locate the holes in the appliance base as indicated.| Use the screws and attach the appliance by using the pilot holes.

Use the supplied angle brackets and fix them to the bottom and back edge of the table. Use the screws for this on both sides| Finally, fix the whole assembly to the floor using M8-m10 Dyna bolts. This will complete the installation.

AIR GAP DETAIL

NOTE:- When installing this unit onto a table, make sure to leave the 4x bolts in place. The bolts are necessary to allow air flow to the underside of the firebox. The removal of these bolts will lead to overheating of the underside of the unit and eventually cause malfunction. The removal of these bolts could void your warranty.

ABOUT CURING

Your stove has been painted with the highest quality silicone stove paint and has special break-in procedures to cure it with heat and make it hard.
VENTILATE WELL
Ventilate the house during the first three times the stove is used. The paint on the stove will give off smoke heavy with carbon dioxide and has an odor, without adequate ventilation, concentrations of smoke could irritate, or be upsetting, so open doors and windows and use a fan if necessary. After these initial burns, the paint will be cured and there should be no more smoke.
DON’T TOUCH DURING CURING
Don’t touch the surface, It will be soft and gummy during the paint curing phase. Once cured, it will not be soft again.
CURES WITH 3 FIRES
Kelman slow combustion wood fires are coated with a high-temperature paint that requires curing, This is done by burning the fireplace so the casing temperatures are hot enough for the paint to cure/harden to the steel surface. High-temperature paint cures at surface temperatures of 180 – 260 degrees, to get the surface temperatures to the required temperatures you need to light a hot fire and let it burn on high for a consistent amount of time 4-6 hours, for 3 separate burns. The paint should emit a slight smell and in some cases, a visible vapor, the first length of active flue should also turn a honey color this is normal and to be expected. Do not light a small cold fire, this will not cure the paint and can lead to blackening of glass and creosote build-up in the flue system.
So remember…

• Ventilate well
• Do not touch during curing
• Cure with 3 fires
• Call your dealer for any questions

INSTRUCTIONS FOR OPERATING YOUR KELMAN SLOW COMBUSTION WOOD BURNING HEATER

1. Open the air inlet fully by sliding the air inlet control to high.

2. Crumple at least three double pages of newspaper into loose balls and place them into the center of the firebox.
   Cross lay at least 15 to 20 pieces of kindling on top of the paper – if pine is used, the size should vary from the thickness of a pencil to that of a knife handle – if softwood is used split it even smaller.

3. Light the paper and close the door. Once the kindling is well alight, add a few pieces of slightly larger softwood, split to approximately 25mm x 50mm (2” x 1”).

4. Close the door and leave the air inlet control on high. When the softwood is well alight (usually 5 to minutes) and coals are starting to form, larger pieces of softwood may be added – five or six pieces the equivalent of 50mm x 50mm (2” x 2”) is ideal.
   The object is to create a fiercely burning fire of reasonable small softwood, which will quickly produce a good bed of glowing coals on the floor of the firebox. This will take from 20 to 40 minutes depending on the quality of the firewood.

5. Larger pieces of softwood may now be added. Half fill the firebox and leave the air inlet control on high until the wood is well alight then close the control approximately a third of its travel. Usually about one hour after lighting, the air inlet control can be further shut down to achieve the desired heat output.
   When adding new firewood it is desirable to fully open the air inlet for approximately 10 to 15 minutes until the new pieces are burning well, then it may be returned to its desired setting.

6. To set the fire for overnight burn – two-thirds fill the firebox with softwood and fully open the air inlet. Once the fire is burning well, the air inlet control should be shut down approximately three-quarters of its travel. Setting the air inlet control may be varied to suit your particular requirements and the quality and size of your firewood.
   Remember wet or green wood may cause a dramatic reduction in the heat output of your heater (refer to “Operating Hints” for more details).

7. Has the flue been inspected at least once every 12 months as it may require cleaning?

8. Clean out excess ash from the floor of the firebox when required. Do not remove all the ash and in particular, leave any pieces of charcoal in the heater as they are good fuel.

9. If the glass door in your heater becomes dirty, your firewood is either green, wet, or both. You may be closing the air inlet down too soon after lighting or after adding new firewood.
   To clean the glass, simply use some of the white ash in the firebox. Apply it with a damp cloth in a circular motion. Remove residue with a clean cloth or paper. Do not clean the glass when the heater is operating.

10. To clean the painted surface, simply dust with a soft duster and wipe over with a damp cotton cloth. Only clean when the heater is cool.

IMPORTANT:
UNDER NO CIRCUMSTANCES SHOULD ANY SOLVENTS SUCH AS METHYLATED SPIRITS, PETROL, MINERAL TURPENTINE ETC BE ALLOWED TO COME IN CONTACT WITH THE PAINTED SURFACE OF THE HEATER AS DAMAGE TO THE FINISH WILL RESULT. IF AN ACCIDENT DOES OCCUR, SPRAY CAN PAINT IS AVAILABLE FROM YOUR NEAREST KEMLAN DEALER.

OPERATING HINTS

To get the best from your Kemlan heater it is essential that you use good firewood and use it correctly Many people do not understand the principle of using a wood-burning appliance and we suggest that it will be worth your while to study the following extract from a well-known American publication.
PRINCIPLES OF COMBUSTION: HOW WOOD BURNS
Technically, wood does not burn. What burns is the volatiles and charcoal that are created. That is why wood will not catch on fire immediately when you put a match to it; it has to first undergo the chemical changes that create the volatiles, and a match does not create enough heat to activate the process. As kindling and paper evaporate the moisture in the wood, the wood absorbs heat. At a certain point, gases are given off and when these volatiles reach 480 degrees F, or the “Flashpoint”, as it is called, they will burst into flame if sufficient oxygen is present. The volatiles gives off more heat than charcoal, which is why a fire with flames (which burns the volatiles) produces more heat than one that is all charcoal.
Since the volatiles is gases and since heat rises, taking the gases with it, it is very easy to create a situation in which most of the volatiles go up the chimney almost as soon as they are produced. This is what happens with a roaring fire and, to a lesser extent, with an open fire. One of the reasons (but only one) that a freestanding wood stove produces more heat than an open fire is that the volatiles are contained within the firebox and are not so quickly dissipated up the chimney. A stove that is baffled is merely one that has an interior construction design to keep the volatiles in the firebox longer; the longer they are in the firebox, the more completely they burn. The more completely they burn, the more heat is produced. It’s that simple.
Since the flames burn the volatiles and produce heat, the ideal situation is the longest possible flame path. As soon as wood burners understand this, they tried to devise ways of making the flame path longer than in an ordinary open fire. Even though the role of oxygen in combustion was not under- stood in Ben Franklin’s time, Franklin did realize the importance of more completely burned volatiles. His solution was to try to invent a downdraft stove – one that sent the volatiles back down through the fire – but he never succeeded in getting it to work. A downdraft goes against the nature of volatiles, which is to rise. In more recent times, there have been some successful downdraft – or partial downdraft – stoves created and
some of the fireplace stoves and units utilize this principle. Ideally, it would be best if the volatiles could be redirected down through the fire several times until they were al- almost totally consumed. This would not only make the maximum use of the heat potential of the wood; it would reduce creosote build-up to almost zero. Perhaps someday an ingenious inventor will design a unit that does this; so far no one has been able to.
MOISTURE AND COMBUSTION
As we have seen, dry wood ignites faster and burns better – with higher heat production – than wet or green wood. The difference between the amount of heat produced by dry wood and green wood is so great that a dry softwood of good grade will produce more heat than green softwood. Green white ash, for instance, is not as good a fuel as dry tamarack.
The reason for the superiority of dry wood is easy to understand. Heat cannot be produced until moisture has been driven off. Since even so-called seasoned dry wood contains approximately 20 percent moisture, it takes time for any fire to begin producing useable heat. Wet wood, which can have a moisture content of over 100 percent (due to the way moisture is measured), will take that much longer to produce heat. Meanwhile, the fire will produce smoke and creosote and very little heat. This was brought sharply to my attention when I installed my first wood heater. To my surprise and delight, I found it comfortably heated eight rooms, where I had expected to heat only two or three. After some time, when I had someone helping me run the fire, I suddenly noticed that the house was chilly. We added more wood and adjusted the draft controls, but nothing we did seemed to help. It finally occurred to me to check the woodpile. My friend had been getting green wood from a stack that was drying, instead of from the dry-wood stack. The difference the green wood made was so dramatic I will never forget it.
HOW TO TEST WOOD FOR DRYNESS
There are two easy ways for even a novice to spot dry wood. Dry wood tends to “check”. Look at the log ends and you will see cracks radiating from the center of the log. If the logs have been split, the cracks will be harder to find because wood tends to split along the cracks.
Another test for dry wood is the sound it makes when two logs are banged against each other. Greenwood will make sort of a dull thud; dry wood makes a nice crisp, sharp sound. Once you have heard the two, you will remember the difference.
FROM THE ABOVE EXTRACT SEVERAL FACTS BECOME APPARENT:

1. It is vital that your firewood be dry and seasoned.
2. A good hot fire of kindling and smaller pieces of fuel must be established before adding larger logs.
3. The larger logs should be well alighted before slowing down the combustion by adjusting the air intake.
4. A hot bed of coals needs to be maintained to ensure continued combustion in the firebox.
5. When new timber is added to the firebox the air control should be opened until the fuel is well alight before damping it down again. This will take from 10 to 20 minutes.
6. When setting the controls for overnight burn you will need to experiment with the settings to suit your particular type of fuel. Very dense softwood requires more air to combust and over-damping will result in charring and smoking causing the glass in the door to become dirty.

The same will apply to fuel that is not fully seasoned or is not dry enough. Kelman has followed a policy since 1969 of checking on all complaints about the poor performance of their heaters and apart from a few instances of incorrect installation (mostly insufficient flue length) all problems have been directly related to the incorrect operation and/or poor fuel. We know you will experience many years of satisfaction from your heater if you follow the above advice.
