| When
it comes to sizing a heating appliance, it's important that
you choose a product that does what it should without heating
you out of your home or requiring a full bore burn 24 hours
a day to provide the necessary heat.
Although
EPA Phase II woodburning appliances are more forgiving than
non-certified wood stoves that are under or oversized, you
should give careful thought to a stove's heating capability,
along with the variables that will have an effect on it.
Our
staff is trained to ask the question that will help us determine
which products are best for you. We'll gather hard-and-fast
data such as your home's size, insulation, plus variables
such as how you plan to operate your stove and what type of
fuel you plan to burn.

Clearances
and Placement
Unless you're adding a fireplace insert or gas log set to
an existing fireplace, hearth appliance placement calls for
some planning on your part. Take a stroll through your home
and visualize where you would like your unit installed.
As
a rule, heating appliances operate best if they're centrally
located. They're best installed on the main floor in one of
the most used rooms in your home. Placing your unit near and
open stairwell helps to draw warm air near the ceiling up
to the second floor, while at the same time channeling cooler
air downstairs. In homes with high ceilings, circulating ceiling
fans help push the heat down to your living space, while optional
or standard fan systems on your appliance will boost heat
output throughout.
If
you're considering an appliance equipped with a fan, locate
likely electrical outlets. If your home has a sunspace that's
exposed to solar heat during the day, install your appliance
on the opposite side of the house to even out room temperatures.
Also consider your family's traffic pattern through the house,
and if you're adding a woodburning appliance, determine where
your fuel supply will be located.
Our
staff can help you plan. Bring along a sketch of your home's
floor plans for us to review, or blueprints if you have them.
If you're considering a fireplace insert, the dimensions of
your fireplace insert are a must. Measure the width and height
of the opening and the depth of your fireplace at hearth level
and 24 inches (610 mm) above the hearth. Also measure the
extension of the hearth in front of the fireplace.
Remember
that there may need to be structural changes to allow for
proper installation. These changes differ by appliance, especially
when it comes to venting. A closer look at what modifications
to expect will help you decide where your hearth will be most
at home.
Clearances
Clearances tell you how close your appliance and its venting
system can be installed to combustibles such as walls and
furnishings.
The
National Fire Protection Agency's Standard 211 (ULC or CSA
in Canada) sets guidelines for listed and unlisted woodburning
stoves and inserts and their venting systems. Most manufacturers
safety test and list their appliances for clearances will
below those standards for different materials that can be
used in installation, such as double-wall connector pipe,
or in the case of fireplace inserts, mantel shields. It's
important to follow the manufacturer's listed clearances for
all hearth appliances, and to keep in mind that combustibles
also include newspaper or firewood near your appliance.
Be
sure to contact your insurance company once installation is
complete. Your homeowner's policy may need to be updated,
and an inspector may need to pay a call to make sure your
installation is both safe and meets local codes.
Nothing
is more important to us than the safe installation of the
products we sell. That's why professional installation is
a must. We make it a priority to keep up with local building
and safety codes to ensure safe, approved installations that
reflect current requirements in our area. Because the most
important things we can offer you and your family are satisfaction,
security and, ultimately, peace of mind.
Chimneys
and Proper Installation
Your stove's chimney system is one of the most important components
to ensure to proper, responsive operation you're looking for.
Most people think of chimney's as a means of releasing exhaust
gases from the fire. But equally important is that they create
a draft from heat rising up the chimney. They "inhale"
room or outside air into your stove for combustion and then
"exhale" skyward what's left.
Without
proper draft, your stove can't do its job and will burn less
efficiently and, if it is a wood-burner, will create more
creosote. It will also release more smoke up the flue. Because
EPA Phase II-approved wood-burning products are more efficient,
they hold most of the heat in the firebox and release more
heat into the home.
The
problem is, in conventional installations with large, existing
chimneys, the flue gases are allowed to expand and cool well
before they reach the top of the chimney. This results in
poor draft and corrosion-causing condensation, which can also
be caused by green wood or improper operation. Other sources
of poor draft include insufficient chimney height and exhaust
fans in tightly insulated homes, which can cause "negative
pressure".
But,
the prefabricated, stainless steel flue liners, chimneys and
chimney connectors we carry are designed to maintain high
flue temperatures with less heat to give your stove the "breathing
room" it needs, by precisely matching the diameter of
your stove's flue collar. They are also safer than ever because
they reduce the formation of flammable creosote.
UL
and ULC listed, HT (high temperature) chimney systems for
wood-burning stoves have been tested to withstand 2,100 degrees
F (1,149 degrees C). Plus, because of their enhanced draft,
they're less likely to "back puff" into your home.
They also make it easier to clean your fireplace insert without
removing it.
For
venting a wood stove or insert into an existing masonry chimney,
we often suggest relining the chimney for safety, increased
performance and to meet local codes. There are two types of
relining. One is a stainless steel liner that extends from
the top of the stove to a point above your roof. Another,
used in masonry fireplaces, is a poured, insulated reline.
A removable "former" that fits your chimney's opening
is inserted, castable refractory material is poured around
it, and the former is removed, leaving a durable, custom-made
refractory liner extending to the top of the chimney. A reline
is a sound solution for masonry chimneys that don't meet code
requirements, or have eroded mortar joints or cracks.
Our
store carries a complete line of listed, approved venting
systems to complete your installation. By matching your product
with its appropriate venting system, we'll be ensuring that
the performance you'll get.
Woodburning
Stoves
A wood stove is most often vented vertically, with a chimney
system through the roof, or through an outside wall, extending
above the roof. Of the two, straight roof venting is better,
because outside wall installation can result in poor draft,
and chimney length or installation may need to be added to
compensate. This is due to outside air temperatures cooling
the chimney and the bends required for the pipe, both of which
can restrict draft. It's also more expensive to install and
clean outside wall installations.
Ceiling
venting, on the other hand, improves performance and almost
always costs less.
A third
option is venting your stove through an existing masonry chimney,
although it should be checked by a professional to ensure
there are no cracks and that it meets code and safety requirements.
In some situations, a reline will be necessary, as previously
discussed.
Your
chimney will need to extend at least three feet (914 mm) above
the point on the roof it penetrates and two feet (609 mm)
taller than any object within 10 feet (3048 mm) of it. Remember
that these are minimum heights, and your chimney may need
to be higher for your stove to operate properly.
Another
requirement for most stoves is floor protection. Floor protection
dimensions vary from stove to stove, and you may want to invest
in an oversized hearthpad for extra space for toolsets and
accessories. We can help you determine the space your stove
and hearthpad will take up in your home. Noncombustible hearthpad
materials required by manufacturers can be finished in stone,
colorful decorative tile or brick to create a showcase base
for your stove.
A double
or triple wall Class A, UL 103 HT (or ULC 2629M) listed, stainless
steel chimney and roof or passes through an outside wall,
turns up, and then extends to the appropriate height above
your roof. A chimney connector pipe must be used to attach
your stove to your chimney system. Both double-wall and single-wall
connector pipe is available. Double-wall pipe can be placed
closer to combustible surfaces, making stove placement more
versatile.
Woodburning
Fireplace Inserts and Stoves Venting Into Masonry Chimneys
Rigid or flexible stainless steel liners (and in the case
of stoves, other system components) vent your stove or insert
from the unit to where the gases exit the flue. Flexible liners
are ideal for masonry chimneys with bends or protrusions.
A poured reline is another option to match your flue's diameter
with your insert or stove.
Woodburning
Factory-Built Fireplaces
Installation will vary between different brands of factory-built
fireplaces, and the manufacturer's specifications for framing
and facing materials must be strictly followed for a safe
installation. Some require a metal strip, installed below
and in front of the unit.
Double
or Triple-wall chimney systems tested to UL 127 standards
extend from the unit to the roof area. Your chimney system
must be approved as indicated in the manufacturer's owner's
manual.
Gas
Stoves and Fireplaces
Gas appliances vent through an outside wall, through a new
or existing prefabricated chimney or a relined masonry fireplace.
Relining is requited by manufacturers, and is important for
proper draft. Gas, when it burns, forms a water vapor, a byproduct
of combustion. In a masonry fireplace, water vapor can seep
into the chimney's surfaces, or into your home.
A reline
with an aluminum or stainless steel gas liner provides a surefire
path for condensation to exit the house. Once the reline is
complete, if there is considerable space between the inside
of the masonry chimney and the liner, or especially if your
chimney is on an outside wall in a cold climate, added insulation
may be needed to prevent condensation.
Type
B gas vent, less expensive than chimney systems for appliances
that burn cordwood, vents exhaust from freestanding gas stoves
and fireplaces. Direct-vent appliances use components sold
with the appliance to vent and introduce combustion air through
an outside wall or thorough the roof.
Gas
Inserts
Aluminum or stainless steel gas liner is used to vent your
gas fireplace insert inside a masonry fireplace. As with other
gas appliances, relining is required by the manufacturer and,
depending on the open area between the liner and the chimney,
added insulation may be necessary to keep condensation from
forming.
Gas
Logs
Vented gas logs must be vented through an existing chimney
with proper draft, with the damper permanently secured in
the open position or removed. |
