1. Hardwood vs. Softwood

Your fireplace’s performance depends on the quality of the firewood you use. One species of wood varies very little to the other in terms of energy content. All seasoned wood contains about 8,000 BTU’s per pound.

Hardwoods have a greater density than softwoods; a piece of hardwood will contain about 60% more BTU’s than an equal size piece of softwood. A cord of seasoned oak (hardwood) would contain about 60% more potential energy than a cord of seasoned pine (softwood).

Most softwoods are coniferous. These are trees with needle-like leaves that stay green all year and carry their seeds exposed in a cone. Examples of coniferous trees are Douglas fir, pine, spruce and cedar. Softwoods, being more porous, require less time to dry, burn faster and are easier to ignite than hardwoods.

Hardwoods are deciduous trees, broadleaf trees that lose their leaves in the fall. Their seeds are usually found within a protective pod or enclosure. Some examples of deciduous trees are oak, maple, apple, and birch. However, it should be noted that there are some deciduous trees that are definitely not considered hardwoods such as poplar, aspen and alder. Hardwoods require more time to season, burn slower and are usually harder to ignite than softwoods. Obviously, you will use the type of wood that is most readily available in your area. However, if at all possible the best arrangement is to have a mix of softwood and hardwood. This way you can use the softwood for starting the fire, giving off quick heat to bring the fireplace up to operating temperature. Add the hardwood for slow, even heat and longer burn time.

Soft woods

• Douglas Fir

• Pine

• Spruce

• Cedar

• Poplar

• Aspen

• Alder

Hard woods

• Oak

• Maple

• Apple

• Birch

10 Heat & Glo • HST48D Owners Manual • 4012-055 • Rev B • 07/25/13

WARNING! Risk of Fire!

• DO NOT burn wet or green wood.

• Wet, unseasoned wood can cause accumulation of creosote.

2. Moisture content

The majority of the problems fireplace owners experience are caused by trying to burn wet, unseasoned wood. Freshly cut wood can be as much water as it is wood, having a moisture content of around 50%. Imagine a wooden bucket that weighs about 8 pounds. Fill it with a gallon of water, put it in the firebox and try to burn it. This sounds ridiculous but that is exactly what you are doing if you burn unseasoned wood. Dead wood lying on the forest floor should be considered wet, and requires full seasoning time. Standing dead wood can be considered to be about two-thirds seasoned, if cut at the dry time of the year.

Burning wet, unseasoned wood will produce less heat output because it requires energy in the form of heat to evaporate the water trapped inside. This is wasted energy that should be used for heating your home. This moisture evaporates in the form of steam which has a cooling effect in your firebox and chimney system.

When combined with tar and other organic vapors from burning wood it will form creosote which condenses in the relatively cool firebox and chimney.

Even dry wood contains at least 15% moisture by weight, and should be burned hot enough to keep the chimney hot for as long as it takes to dry the wood out

- about one hour. To tell if wood is dry enough to burn, check the ends of the logs. If there are cracks radiating in all directions from the center, it is dry. If your wood sizzles in the fire, even though the surface is dry, it may not be fully cured.

3. Seasoning

Seasoned firewood is nothing more than wood that is cut to size, split and air dried to a moisture content of around 20%. The time it takes to season wood varies from around nine months for soft woods to as long as eighteen months for hardwoods. The key to seasoning wood is to be sure it has been split, exposing the wet interior and increasing the surface area of each piece.

A tree that was cut down a year ago and not split is likely to have almost as high a moisture content now as it did when it was cut.

To season wood:

• Cut logs to size

• Split to 6 in. (152 mm) or less

• Air dry to a moisture content of around 20%

- Soft wood - about nine months

- Hard wood - about eighteen months

Seasoning time may vary depending on drying conditions.

4. Storing Wood

Splitting wood before it is stored reduces drying time.

The following guideline will ensure properly seasoned wood:

• Stack the wood to allow air to circulate freely around and through the woodpile.

• Elevate the woodpile off the ground to allow air circulation underneath.

• The smaller the pieces, the faster the drying process.

Any piece over 6 in. (152 mm) in diameter should be split.

• Wood should be stacked so that both ends of each piece are exposed to air, since more drying occurs through the cut ends than the sides. This is true even with wood that has been split.

• Store wood under cover, such as in a shed, or covered with a tarp, plastic, tar paper, sheets of scrap plywood, etc., as uncovered wood can absorb water from rain or snow, delaying the seasoning process. Avoid covering the sides and ends completely. Doing so may trap moisture from the ground and impede air circulation.

Heat & Glo • HST48D Owners Manual • 4012-055 • Rev B • 07/25/13 11

5. Burning Process

Fire requires fuel, air and heat. If heat is robbed from the fireplace during the drying stage, the new load of wood has reduced the chances for a good clean burn.

Always burn dry, seasoned firewood.

6. Creosote Formation

When wood is burned slowly, it produces tar and other organic vapors which combine with expelled moisture to form creosote. The creosote vapors condense in the relatively cool chimney flue of a newly-started or a slow-burning fire. As a result, creosote residue accumulates on the flue lining.

When ignited, creosote creates an extremely hot fire which may damage the chimney or even destroy the house.

The chimney shall be inspected at least annually before lighting, or once every two months during heating season.

When creosote has accumulated it shall be removed to reduce the risk of a chimney fire.

7. Processed Solid Fuel Firelogs

Manufactured firelogs may be used with this fireplace.

Hearth & Home Technologies recommends the use of

UL Classified processed fuel firelogs. Follow the manufacturer’s lighting and safety instructions.

Using firelogs may require more frequent chimney inspections and cleaning.

Do not poke or stir the logs while they are burning. Use only firelogs that have been evaluated for the application in manufactured fireplaces and refer to firelog warnings and caution markings on packaging prior to use.

D. First Fire

Before lighting your first fire in the fireplace, make certain that:

• refractory is in place

• all labels have been removed

E. Lighting Instructions

NOTICE: You must establish a good draft to prevent smoke spillage into the room.

The first three or four fires should be of moderate size to allow the oils and binders to be burned from the fireplace and the refractory and paint to cure. You may notice an industrial odor the first few fires. This is considered normal.

Use well-seasoned wood.

• Open the flue damper to a fully open position.

• Place crumpled or twisted paper under the fireplace grate.

• Loosely arrange kindling or small pieces of wood to form a ‘tent’ on the fireplace grate.

• Pre-warm the flue to establish a draft to help reduce smoke spillage during start-up. Hold a rolled up piece of burning newspaper under the flue damper for a few moments.

• Light the crumpled paper to ignite the kindling.

• Add small pieces of wood until a hot bed of embers has been established.

• Add a minimum of three average size pieces of split firewood, placed to allow combustion air and flames between them.

WARNING! Risk of Fire! Keep combustible materials, gasoline and other flammable vapors and liquids clear of the fireplace.

DO NOT:

• store flammable materials close to the fireplace

• use gasoline, lantern fuel, kerosene, charcoal lighter fluid or similar liquids to start or “freshen up” a fire in this fireplace.

• When wood is burned slowly, it produces tar and other organic vapors, which combine with expelled moisture to form creosote. The creosote vapors condense in the relatively cool chimney flue of a slow-burning fire. As a result, creosote residue accumulates on the flue lining. When ignited, this creosote makes an extremely hot fire.

• Remove all ash from the firebox and extinguish all hot embers before disposal. Allow the fireplace to cool completely.

• Close the door tightly.

• Remove the top of the termination cap as shown in

Figure 4.1 to clean the cap and chimney.

• The creosote or soot should be removed from the chimney with a brush specifically designed for the size of chimney in use.

• Reinstall termination cap.

• Clean out fallen debris from the firebox.

Risk of Fire! Ignited creosote is extremely

HOT. Prevent creosote buildup.

Troubleshooting

Start Fire Problems

Can’t get fire started

Excessive smoke or spillage

Burns too slowly

Smolders, sizzles

Possible Cause

Not enough kindling/paper or no kindling/paper

Damper closed/not fully open

Not enough air for fire to ignite

Solution

Use dry kindling, more paper. Arrange kindling & wood for air movement.

Open damper.

Check for restricted cap/shroud.

Open air kit (if installed).

Check for flue blockage.

Pre-warm flue before starting fire (refer to starting fire section).

Check for adequate vent height (refer to chimney assembly section).

Open window below the fireplace towards the wind.

Wood condition is too wet, too large Use dry, seasoned wood (refer to wood fuel section).

Bed of coals not established before adding wood

Flue blockage such as birds’ nests or leaves in termination cap

Start with paper & kindling to establish bed of coals (refer to starting fire section).

Have chimney inspected for creosote and cleaned by a certified chimney sweep.

Fire burns too fast

Down draft or negative pressure

Competition with exhaust devices

Extremely dry or soft wood

No glass doors

Overdrafting

Do not use exhaust fans during start-up (refer to negative pressure section).

Open window below the fireplace towards the wind.

Mix in hardwood.

Mix in less seasoned wood after fire is established (refer to wood fuel section).

Add glass doors to slow down air flow.

Check for correct vent height; too much vertical height creates overdrafting.

Check location of vent termination (refer to chimney assembly section).

A. FAQs

Hearth & Home Technologies assumes no responsibility for the improper performance of the fireplace system caused by inadequate draft due to environmental conditions, down drafts, tight sealing construction of the structure, or mechanical exhausting devices which will create a negative air pressure within the structure where the fireplace is located.

If smoke spillage occurs from a fireplace opening when the door is open, there is either a leakage in the flue, a blockage in the flue, or some condition is affecting draft

Understanding and differentiating the conditions which can cause each of these kinds of spillage problems is essential to their solution.

• Flue Leakage

Check for improperly connected flue joints or a damaged flue joint in the chimney system. Such leakage would reduce draft (air would be drawn in through the leaks rather than through the fireplace).

The result might be difficult start-up and smoky fires that might spill if other adverse draft conditions accompany this problem.

• Flue Blockage

The damper should be open.

Check for objects that may have fallen down the chimney.

Flue draft is measured as negative pressure in the chimney. The amount of negative pressure determines how strong the draft is. The draft is important because it draws the combustion air into the fireplace and pulls the smoke out of the chimney.

There are three basic criteria essential in establishing and maintaining flue draft:

• availability of combustion air

• heat generated from the fire

• diameter and height of the flue system

These three factors work together as a system to create the flue draft. Increasing or decreasing any one of them will affect the other two and thus change the amount of draft in the entire system.

If the fire is hard to start and smoke spills out of the fireplace, or you find it difficult to establish and maintain a moderately high burn rate, then the flue draft is too low and corrective measures must be taken.

Be sure you have air available for combustion and that your firewood is dry and well seasoned. Build your fires properly and according to the instructions given in operating instructions, “Starting a Fire”. Be sure your flue system is installed correctly and that it is the proper diameter and height. Check for the following:

• All chimney sections are properly installed.

• The chimney is clean and free of creosote or soot buildup.

• Make sure overhanging trees and branches are cut back within ten feet of the top of the chimney and the chimney is free of debris from animals.

• Ensure the chimney cap is clean and free of any buildup of soot or creosote if cap is equipped with a spark arrestor screen.

• The wood being used in dry and well seasoned.

If you still suspect you have a low draft problem it may be necessary to increase the volume of air in your flue system. Since the diameter of your flue system is matched with the size of the flue collar and should not be changed, then the height of the system must be increased. Add chimney sections one at a time until the draft improves.

In some cases, regardless of what you do, it can still be difficult to establish the proper flue draft. This is especially evident when using an exterior factory-built chimney or exterior masonry chimney. Try holding a burning rolled up newspaper as close to the flue outlet as possible for a few minutes, then light the paper under the kindling. The heat generated from the burning rolled up newspaper should help get the draft established.

Still other factors can affect how well your flue system performs. Neighboring structures, high winds, tall trees, even hillsides can affect air currents around the chimney. Well designed chimney caps are available that can help. Your fireplace dealer is the local expert in your area. He can usually make suggestions or discover problems that can be easily corrected allowing your fireplace to operate correctly as it has been designed, providing safe and economical heat for your home.
