Isle Royale Wood Stove

250-5763C

BURNING PROCESS

In recent years there has been an increasing concern about

air quality. Much of the blame for poor air quality has been

placed on the burning of wood for home heating. In order

to improve the situation, we at Quadra-Fire have developed

cleaner-burning wood stoves that surpass the requirements

for emissions established by our governing agencies. These

wood stoves, like any other appliances, must be properly

operated in order to insure that they perform the way they

are designed to perform. Improper operation can turn most

any wood stove into a smoldering environmental hazard.

KINDLING or 1st STAGE

It helps to know a little about the actual process of burning in

order to understand what goes on inside a stove. The first

stage of burning is called the kindling stage. In this stage, the

wood is heated to a temperature high enough to evaporate

the moisture which is present in all wood. The wood will

reach the boiling point of water (212°F / 100C) and will not

get any hotter until the water is evaporated. This process

takes heat from the coals and tends to cool the stove.
Fire requires three things to burn: fuel, air and heat. So,

if heat is robbed from the stove during the drying stage,

the new load of wood has reduced the chances for a good

clean burn. For this reason, it is always best to burn dry,

seasoned firewood. When the wood isn’t dry, you must open

the air controls and burn the stove at a high burn setting for

a longer time to start it burning. The heat generated from the

fire should be warming your home and establishing the flue

draft, not evaporating the moisture out of wet, unseasoned

wood, resulting in wasted heat.

The air control to the right of the stove is called the Start-Up

Air Control; it is used during the kindling stage of burning.

It must be closed (pulled out) after the first 5 to 15 minutes.

Figure 18A.

2nd STAGE

The next stage of burning, the secondary stage, is the period

when the wood gives off flammable gases which burn above

the fuel with bright flames. During this stage of burning it is

very important that the flames be maintained and not allowed

to go out. This will ensure the cleanest possible fire. If you

are adjusting your stove for a low burn rate, you should

close down the air to the point where you can still maintain

some flame. If the flames tend to go out, the stove is set

too low for your burning conditions. The air control slide in

the center of the stove, beneath the ashcatcher, is the one

used to adjust the stove for burn rates. This is called the

Primary Air Slide Control.

OPERATING INSTRUCTIONS

IMPORTANT - PLEASE READ BEFORE USING STOVE

Do not over-fire.
Over-firing may ignite creosote or will damage

the stove and chimney.
To prevent over-firing your stove, DO NOT:
• Use flammable liquids

• Overload with wood

• Burn trash or large amounts of scrap lumber

• Permit too much air to the fire

WARNING

Fire Risk

Symptoms of over-firing may include one or more of the

following:
• Chimney connector or appliance glowing
• Roaring, rumbling noises
• Loud cracking or banging sounds
• Metal warping
• Chimney fire

1. Symptoms of Over-Firing

2. What To Do if Your Stove is Over-Firing

• Immediately close the door and air controls to reduce

air supply to the fire.

• If you suspect a chimney fire, call the fire department

and evacuate your house.

• Contact your local chimney professional and have

your stove and stove pipe inspected for any damage.

• Do not use your stove until the chimney professional

informs you it is safe to do so.

Hearth & Home Technologies WILL NOT warranty stoves

that exhibit evidence of over-firing. Evidence of over-firing

includes, but is not limited to:
• Warped air tube
• Deteriorated refractory brick retainers
• Deteriorated baffle and other interior components
