Surdiac Coal Stove 'TIPS'
“Breaking In” Season Your New Cast Iron Parts
A cast iron stove should be “broken In” much in the same way a new car with a cast iron
engine is: gradually. After installing new cast parts from Myer’s Furniture, it is mandatory that
five consecutive individual small coal fires be built in the stove prior to using it continuously
with the hopper fully loaded. The five “firings” are successive small coal fires being built with
a complete cooling off of the stove to room temperature after each fire has gone out. It is not
acceptable to build a small fire and keep it going for 2 - 3 days on a low stove setting. The
stove must be cooled off completely after firings in order to properly heat treat all the metal
parts on the stove. Only fill the stove with coal into the hopper about an inch with the
thermostat set no higher then 1 – 2.
Alternet Method to Season New Small Cast Iron Parts: Preheat oven at 325 degrees. Place
cast iron on rack. Every 30 minutes increase the temperature by 25 degrees until the oven is
maxed out. DO NOT TOUCH THE CAST IRON! IT WILL BE VERY HOT!! Let the cast iron cool
to room temperature. Repeat the process to increase the temper of the metal.
These steps should be taken in order to prevent premature damage of new cast iron. This will
harden the cast iron for a full burn.
Gasket material is very durable, gets dirty and old looking, but has been known to last over 25
years. A pressure impression does not indicate the need for replacement, but, a piece or section
of gasket missing, worn thru or loose and out of position does. A loose and out of position
gasket can often be corrected by using a thin coat of retort/furnace cement as a bonding agent.
If the impression in the Pyrex or ash door gasket is so deep that the door can be compressed
after latching, adjusting the latch catch will generally be the fix rather then replacing the gasket.
Gaskets are intended to “seal the gap” between two metal pieces, but are not intended to hold
pressure. If you decide a gasket needs replacing, you can purchase them from Myer’s Furniture.
Do not attempt to clean the glass when it is hot. Allow it to cool and wipe with a cloth and a
vinegar water solution. Do not scrape the glass with anything or use any abrasive materials.
Scratches made in the glass can later develop into cracks. Replace cracked or broken glass with
4mm ceramic replacement glass from Myer’s Furniture.
The thermostat senses changes in the stove operating temperature and opens or closes a valve
in the rear of the stove, regulating the amount of air the fire receives. The thermostat dial, on the
right hand side of the stove, has been set in the factory and is not to be adjusted except by a
qualified technician. Do not force the thermostat dial; turn it only as far as it will naturally go.
When the stove is hot, the dial will not go back to zero. The thermostat should be set as follows:
0 – 1 Mild temperature or nighttime use, 1 – 2 Normal usage, 3 – 4 Cold weather usage, 5 – 8 High
heat setting. Do Not Use the High Settings for a duration of more than Two Hours. After
operating in this high range for two hours, the stove must be operated at a setting of 3 or less
for the next 24 hours.
Keeping the Fire Burning
Ash that forms around coal as it is burning needs to be physically removed. This will need to
be done about every 12 hours on low settings and every 6 hours on medium to high settings.
Open the glass door using your poker to push the ash down along the edge of the fire basket
on each side and along the front. Close the glass door before starting the riddling process and
open the ash pan door. You will be looking for a live coal red reflection in the ash pan while
riddling to know when the ash has been removed allowing the live red coal to rest on the grates.
There are 3 openings above the ash door where the poker must be inserted in order to shake
down the ashes. When you introduce the poker into each opening, use a sawing motion, starting
in one of the front corners of the fire box sawing your way across the fire box to the other front
corner. Be sure to get the corners of the fire box cleaned out and that you are poking the whole
way to the back of the fire box. If the ashes are not thoroughly removed, less space will be
available for coal combustion resulting in less heat. Do not employ a side-to-side swaying
motion when shaking the stove down because it will result in live and new coal mixing with the
ash making it harder to push the poker to the back of the fire box before all the softer ash has
been removed. After shakedown, the coal hopper should be refilled. Removed ashes should be
poured into a metal container awaiting disposal.
A coal fire burns from the bottom up through the pile of coal leaving ash on the bottom, then
live coal, then new coal on the top. Ideally, your riddling process should cause the ash on the
bottom to drop through the grates allowing the undisturbed live coal to settle down to the grates
with new coal flowing from the hopper as it fills in the top of the firebox area.
Often the coal bed will not have burnt evenly from side to side causing the need for more
riddling in areas so that an even red reflection is observed in the ash pans under the live coal.
This is why the Surdiac stove does not have a shaker grate system for riddling. A poker method
allows you to remove ash, as the need arises, as you saw across the grate not wasting coal or
needing to sift through ash to recover it. A poker method also allows you to discontinue riddling
either the left, right or both openings cutting down the size of the live fire area by thirds as heat
demands require. If you try this, always riddle the middle!
NOTE: After extended use of the poker, it will become shorter from wear, making it more difficult
to remove ash from the back of the firebox. Inspect the poker yearly, making sure it is at least
15” long (overall length including handle). Replacements can be purchased from Myer’s Furniture.
At the end of the heating season the flue, pipe, and stove must be thoroughly cleaned to prevent
rust and corrosion from the acidic coal ash.
Remove the stove pipe and take the entire assembly outside. Be careful not to disturb the
balance weight of the barometric damper. Wash and brush the inside of the pipe until it ‘shines’.
After the pipe has dried, coat the inside with oil to a solution made from 1 lb. of baking soda to
1 gallon of water. Reassemble the pipe, sealing the joints and set it aside until the stove is
cleaned. Remove the ash pans, furnace paddles, fire baskets, hopper, grates, and grate cradle
and wash them with a brush. Vacuum the interior and exterior of the stove. Open the clean
out traps on the back of the heat exchanger. Vacuum and brush the loose ash from the
bottom of the heat exchanger in the back and the bottom of the ‘tubes’ connecting to the
fire box. DO NOT use anything on the inside of a porcelain coated heat exchanger that
would scratch the coating allowing the ash to come into contact with the bare metal
causing rust. Reassemble the clean out traps and all the stove parts making sure the
hopper is in the raised position. Check for loose or missing gasket sections. Loose gaskets
can be re-attached with gasket or furnace cement, missing sections should be fixed by
replacing the entire gasket which can be purchased from Myer’s Furniture. It is best
to leave the stovepipe disconnected during the summer. With the pipe connected moist air
is continuously pulled through the stove and can cause it to rust.
· Never over fire the stove. If any part of it glows, you are over firing, and serious damage to
the stove or a chimney fire could result.
· Never operate your Surdiac stove with the doors open, except for normal tending of the fire.
· Teach children that the stove is hot and should not be touched.
· Never burn trash of any kind in the stove.
· Do not dry clothes over the stove, they could fall and ignite.
· Keep loose flammable materials at least 48 inches away from the stove.
· Never use the stove if there are combustible gases in the house. A few examples of
combustible gases are the fumes from certain cleaning fluids, adhesives, and paint.
· Always wear protective gloves when adding fuel to the fire and riddling the ash.
· Allow the poker to cool in a safe place after riddling the ash.
· Use only premium grade Pea size anthracite coal with 7% to10% ash content in your
Surdiac stove. Never use synthetic logs or fireplace coal.
· Never use gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter fluid, or similar
liquids to start or “freshen up” a fire in a Surdiac Stove. Keep all such liquids well away
from the heater while it is in use.
· Never operate your Surdiac stove with cracked or broken glass. Replace damaged glass
with ceramic glass 4mm in thickness available from Myer’s Furniture.
· Avoid creating a low pressure condition in the room where the Surdiac stove is
operating. Operating an exhaust fan or clothes dryer could create a low pressure area,
causing poisonous gases to come out of the stove into the room.
· Do not use andirons in this stove.
· This stove is not approved for use in mobile homes.
