Insert. If any odor persists, contact your dealer or an
authorized service technician.
If you adhere to the break-in procedure, as well as all
other operating procedures in this manual, the cast
iron and soapstone firebox lining of your Fireplace
Insert will give you many years of trouble-free use.
Avoid the following conditions that can cause the
soapstone or cast iron pieces to break:
Do not throw wood into the Fireplace Insert.
Do not use the door as a lever to force wood into
the Fireplace Insert.
Do not load wood that is encrusted with ice into a
burning, hot stove as the thermal shock can
cause damage.
Do not use a manufactured log grate. Burn the
fire directly on the soapstone that lines the
bottom of the firebox.
The bottom layer of soapstone in the firebox is
intended to prevent thermal stress to the cast iron,
and should remain in place at all times.
Do not over-fire the Fireplace Insert.
(Refer to
page 25).
Building a Break in Fire
1. Open the front door and place five or six double
sheets of tightly twisted newspaper in the center
of the firebox. Arrange kindling in a crisscross
pattern over the newspaper. Kindling should be
approximately ten pieces, 1/2" (13 mm) in
diameter and 10" to 18" (254 mm to 457 mm)
long.
2. Fully open the primary air control by pulling the
control handle fully out, away from the firebox.
3. Light the paper under the kindling. Leave the
front door slightly ajar momentarily until the
kindling has started to burn and draft begins to
pull.
4. Close the door and allow the fire to burn. Keep
the front door closed while the Fireplace Insert is
in use.
5. Keep a watchful eye on your fireplace insert to
maintain a steady, low-heat fire. Your first fire
should make the Fireplace Insert warm but
not
hot to the touch
. At most, add only a few small
chunks of wood to the fire to reach safe break-in
temperatures.
6. Once the Fireplace Insert is warm but
not hot to
the touch,
close the primary air control by
pushing it in fully toward the firebox to allow the
fire to die out completely.
7. Let the Fireplace Insert return to room
temperature.
Your first fire and first fire each season thereafter
should be built and maintained as outlined above.
Your patience will be rewarded by a properly
seasoned Fireplace Insert.
Note:
Because of the cool flue gas temperatures
present during the break-in procedure, creosote
may build up rapidly. Your door glass may also
get dirty. A good hot fire will clean it. We
recommend a visual inspection (and cleaning if
necessary) of your stovepipe and chimney once
the break-in procedure is completed.
Operating Your Insert Efficiently
Your Clydesdale insert is designed to burn firewood
cleanly and efficiently. The following operational tips
explain how to obtain the most heat possible with
minimal creosote build-up and emitted pollutants
.
Burn Rate
There are four basic burn rates: high burn, medium
burn, low burn, and overnight burn. Each has its own
purpose.
High Burn Rate:
A high burn rate is recommended
once or twice a day to fully heat the stove and
chimney; this also helps keep the amount of creosote
in your stove and chimney to a minimum.
After the fire is established and both the stove and
chimney are hot, create a high burn for maximum
heat output. Pull the primary air control out so that it’s
fully open or almost fully open. Fully load the firebox
with wood on a bed of hot coals or on an actively
flaming fire.
After you have attained a high burn rate, monitor the
stove temperatures frequently to ensure that the
stove is not over-fired. The surface temperature on
top front of the insert (firebox body under grill) should
not exceed 600°
Fahrenheit (316°
Celcius). Once you
understand how your insert burns and heats in your
particular setting, you can easily create a high burn
rate without risk to the stove or chimney.
When your room’s temperature is comfortable,
maintain your fire by loading smaller quantities of
wood. Burning smaller amounts of wood at a high
burn rate creates the least amount of creosote in your
