1. About a Natural Draft Diesel Stove
A Dickinson diesel stove has many advantages to other heating appliances.
They can be run on no power but has a 12v draft assist fan to provide draft
assistance. Our stoves are equipped with simple but reliable internal
components including a gravity feed oil metering valve to a vaporizing oil
burner where the fuel vaporizes by natural draft to burn a beautiful clean fire
in the viewing combustion chamber. A vaporizing oil burner is designed to
transform oil to a vapor state and then burn the vapor. Vaporizing is
achieved by the oil reaching 465 F. Once the oil is vaporized, it becomes
flammable and an efficient and clean combustion is the result.
To obtain a clean and efficient combustion, 3 factors must be in a balanced
proportion.
1. Draft- the volume of air rising through the exhaust chimney.
2. Oxygen- replacement supply of fresh air.
3. Fuel- Input in proportion to the supply of draft and oxygen.
Dickinson diesel stoves can also be calibrated to run kerosene (K) and stove
oil (S). See “Fuel Variations” on Pg. 27. This code will be indicated on the
side of the valve.
A hot water coil can be factory installed or added later to also enjoy water
heating from your Dickinson diesel stove. Hot water coils are available in a
1 turn coil for all model stoves to heat approx. 5-10 gallons of water. Hot
water coils are also available in 2 turn coils for all models except the Bristol
stove to heat approx. 15-20 gallons of water.
2. Important Notes
Here are some important notes to remember when installing a Dickinson
diesel stove:
•Mounting & location, 12v power hook-up, minimum 4ft and a
maximum 8ft of chimney, the location of hole for the chimney & the
fuel supply.

www.dickinsonmarine.com ~ [e-mail]
Form#7.2-248 Issue#2

•VERY IMPORTANT: Unrestricted permanent fresh air inlet
required to draw in outside air needed for correct operation.
•Fuel must be filtered and not exceed a pressure of 4 psi or a fuel
pressure regulator must be used to avoid dangerous flooding
(Dickinson part# 20-003).
•A barometric damper must be installed to help regulate the draft. A
barometric gives you more control in the “fuel to air” mixture needed
for correct operation. The valve controls the fuel whereas the fan
increases the air and the barometric decreases the air (See Pg. 9).
•Install a CO alarm.
***Low Sulfur Diesel Fuel Baffle maybe needed if using low sulfur diesel.
3. Ventilation
Do NOT operate this stove in an enclosed area without a permanent fresh air
inlet designated for your stove. This is required to draw in outside air for correct
operation. To guarantee that fresh air is available for your stove, good
ventilation is essential. You MUST replace the air inside your boat at the same
rate that the stove is removing it. The higher the stove’s burning rate, the more
air the stove will require. If the air flow is blocked or restricted, the stove will
burn inefficiently, create soot, blow out and can even be a very dangerous health
hazard.
A permanently open fresh air inlet MUST be installed or dedicated to the stove.
This inlet must be at least 3" in diameter. Ducting to the stove is also an option.
It is important to create and maintain a positive pressure inside the boat. High
winds can draw air out from the boat and thus create a negative pressure. This
condition can result in down drafts. Ensure that when you do have windows
open that they do not create a suction effect in the cabin due to the window’s
position and the wind direction. In a similar way, it is possible for the air intake
on your engine to suck the air out of a cabin if it is not properly vented.
Your stove is a natural draft appliance and it creates its draft pressure like a
chimney in a wood stove. The rising, heated air in the chimney pulls fresh
air into the stove as it rises up the chimney and exits the flue cap. The
greater the draft pressure, the more able the stove will be to resist strong

Form#7.2-248 Issue#2
6
winds, overcome flue elbows that inhibit draft and the hotter you will be
able to get your stove without sooting. A CO alarm should be installed in the
boat. We also recommend the Dickinson high heat shut-off #02-210.
4. How Does the Chimney affect the Stove?
The stove does not create the draft for a natural draft appliance to operate; it
is the chimney that creates the draft for operation. The purpose of a chimney
is to take the combustion products (smoke and gasses) from the appliance to
the atmosphere outside your boat, and at the same time, to draw air in for
combustion into the appliance. This movement of combustion air and
exhaust is called draft.
In essence, it is the difference in pressure between the air inside the chimney
flue and the outside air that creates this movement. Warmer, lighter gases in
the flue will move upward.
To keep the pressure conditions favorable, we need a tall column of warm
air inside the chimney, and cooler air outside. The warm air will tend to rise,
drawing the exhaust from the appliance out. As air exits the chimney, fresh
air for combustion is drawn into the appliance. The stronger the upward draft
in the chimney the more likely you won’t experience downdraft.
Important Factors of the Chimney
Since draft is a measure of pressure, chimney draft is affected by pressure
conditions in the boat. Several factors come into play:
1. Adequate air. First, there must be adequate air movement into the
boat to make up for the air exiting through the chimney. If the boat is
very tightly insulated, the volume of air drawn up the flue will exceed
the volume of air entering the boat, and the boat will gradually
become depressurized. With lower pressure in the boat than outside,
there will be a tendency for air to be drawn back into the boat from all
available openings including down the chimney.
2. Air movement in the boat. Second, air movement in the boat must
not interfere with the chimney. As air flows out through the one
window, air is drawn from another to replace it. This is called the
stack effect, since the boat acts like a stack, or chimney. If the stack
effect is powerful enough, it will overcome the chimney's upward
draft and pull replacement air (and smoke) into the boat through the
chimney.

Form#7.2-248 Issue#2
7
3. Competition for available air. Third, there must not be too much
competition from other devices in the boat, such as exhaust fans, a
large engine or air-exchange systems. If something else is sucking the
air out of the boat, the chimney might not be powerful enough to
overcome it, and exhaust might be drawn back into the boat from the
chimney.
4. Proper chimney design. And finally, a chimney must be designed to
accommodate the volume and type of exhaust being emitted by the
appliances it serves. This involves correct sizing, adequate height, and
proper construction. See the “Chimney Pipe” section on pg. 9.
Since the chimney draft is affected by so many factors, draft problems
can be complicated to find.
Testing the Draft
To find where the air is being drawn, twist a paper towel into a wick, light it
and blow it out to create smoke. Placing the smoking wick near the open
hatches, windows or vents will lead you to the location. Installing or opening
opposing vents will allow the air to come in from a path of least resistance
and not disturb the draft in the chimney.
Downdraft
A common reason for downdraft is burning the heater too low (too much air
in the burner and not enough fuel). If the flames are burning below the top
burner ring and inside the burner pot then it is burning inefficiently causing
the draft to be too weak going up the chimney allowing downdraft down the
chimney. When the flames are burning above the top ring then the natural
draft is at its strongest so it can fight against downdraft.
5. Installing your Stove
Location
Plan your stoves location prior to installing to ensure the location chosen
will fit the specifications and safety clearances. Combustible material closer
to the stove then the specified safety clearances must be lined with insulation
or millboard and a metal liner with a .5” standoff for air movement behind.
Another alternative is using insulation or millboard and ceramic tile. The
back of the stove and the first length of chimney pipe should also be lined
with such material. See diagram below.

www.dickinsonmarine.com ~ [e-mail]
Form#7.2-248 Issue#2
8
Safety Clearances
Above- 3ft, Sides- 2”, Behind- 2” *with protective material.
Facing Direction
The stove ideally should face the bow or stern of the boat, particularly on a
sailboat. Fuel is gravity fed from the oil metering valve into the burner so if
the valve should drop below the level of the burner, the fuel would not flow
uphill into the burner, which will put out the fire. In a beam-facing
installation, the oil metering valve may have to be relocated to the side of the
stove. There are holes located on the side to hold the repositioned valve
bracket. See diagram below. This can’t be done on the Bristol model as it
must face port or starboard only. This will allow the stove to operate up to
15 degrees. If you have any doubt regarding the need for a valve bracket,
please email us. [email protected]
Note: the stoves valve & burner should be in line with the boats keel.
Mounting

www.dickinsonmarine.com ~ [e-mail]
Form#7.2-248 Issue#2
9
There are holes provided in the side panels at the front of the stove to allow
appropriate fasteners to secure it to the cutout. There is also a tie down bar
supplied to fasten to the bottom back of the cutout, once fastened, side the
stove into the cutout so the side panels are hooked underneath the bar. The
drip tray will then fit under the bottom of the stove.
**REMEMEBER: remove all protective plastic on ALL parts of the stove.
Chimney Pipe
The location and configuration of the chimney stack is very important to the
operation of the stove. A long, straight chimney stack will ensure a strong
draft for correct operation. The diameter of the chimney must be what is
specified. We recommend that the length of your chimney is a straight 5-6ft
run with a minimum of 4ft long and a maximum of 8ft. Avoid using elbows
and if necessary, use 45 degree elbows and allow for as much straight pipe
as possible with a minimum of 12” (28 cm) from the top of the heater. There
is no connector to connect the chimney pipe to the stove. There is a flue
collar already attached to the top of the stove and the pipe can attach by
squeezing the pipe into an oval shape and fitting it over the flue collar.
Chimney Pipe Diameters
Bristol Stove- 4” diameter chimney (10cm)
Bering, Pacific, Adriatic, Atlantic & Beaufort Stove- 5” diameter chimney
(12.5cm)
Barometric Damper
We have 2 options for installing the barometric damper into your chimney.
You can either have the barometric attached to a 22” stainless pipe to be the
first piece of pipe of your chimney off the top of the stove or a 7” piece of
pipe that you can fit into your chimney 12” to 24” from the top of the stove.
Bristol Stove:
Part# 17-001: 4” x 22” stainless pipe with barometric
Part# 17-010: 4” x 7” stainless pipe with barometric
Bering, Pacific, Adriatic, Atlantic & Beaufort Stove:
Part# 18-001: 5” x 22” stainless pipe with barometric
Part# 8-010: 5” x 7” stainless pipe with barometric

www.dickinsonmarine.com ~ [e-mail]
Form#7.2-248 Issue#2

The barometric damper should be installed in oil and solid fuel stoves. The
purpose is to maintain a strong draft without causing too much air to the
“fuel to air” mixture. When the damper is adjusted, the draft is altered by
allowing air to be pulled into the chimney by the air inlet on the damper and
not pulled into the burner. This gives you more control. Having a barometric
allows you to burn your stove at lower temperatures giving you the control
to adjust the draft once the fuel is adjusted to ensure a clean burn.
Install the barometric tee pipe with the front flap facing fore and aft. In order
for the barometric to work efficiently it must be installed between 12” and
24” from the top of the stove. If using a flue guard, turn the barometric tee to
the back as it does not have to be seen to work
To adjust the flap on the barometric, back off the jam nut and turn the
counterweight so the flap is standing closed. Once the stove has been
burning for some time and the room temperature is starting to rise, it is a
good time to do the adjustment. Adjust the counterweight so the flap starts to
open (aprox 6mm or ¼”). This will allow air to enter the barometric tee and
reduce the air entering the burner. This will help the flame to burn above the
top burner ring. If the flame is still burning below the ring, adjust the flap
open another 3mm or 1/8”. At this time, if there is flames burning below the
top burner ring and the barometric flap is open aprox 9mm or 3/8”, do not
adjust the flap open any further and increase the valve setting until the flame
is burning above the top ring.
Tie Down Bar Install
The tie down bar is for securing the back of the stove. Install the bar at the back of
the cut-out so the stove bottom will slide under it. There are screw holes for the
front of the stove.

Form#7.2-248 Issue#2

Deck Fitting
To install the thru deck fitting, a hole must be cut in your deck. Depending on
the diameter of the chimney stack will depend on the size hole that needs to be
cut. There should be a 1” clearance all around the chimney pipe. For example, a
5” diameter exhaust pipe would require a 7” hole drilled in the deck and a 4”
pipe would have a 6” hole. Once a hole is cut, you can line the raw hole with
epoxy, caulking or a metal liner to finish it off. Just ensure there is a 1” air gap
between the side of the hole and the chimney pipe.
The thru-deck fitting includes a stainless steel dress ring for the interior of
the cabin and a neoprene rubber gasket to better seal the fitting on the deck
side. Depending on the contour or the angle of the cabin top, you may need
to make a hardwood spacer block. One surface of the block would be a level
plane to mate to the deck cap. The other would match the angle or contour of
the cabin top. A hole through the center of the block would also be 2 inches
greater then the diameter of the flue pipe.
*The Bristol model has a 4” diameter pipe so it would need a 6” hole.
Exhaust Cap
The Dickinson DP or H style exhaust caps are most recommended. The
exhaust cap will fit over the crimp on the deck fitting or flue pipe. The
location of the exhaust cap above deck must be clear of any immediate
obstruction that may cause unusual air movement or turbulence.
CAUTION: The Exhaust Cap gets hot when the stove is operating.

Stove Installation Diagram
Securing your Stove
When installing your Dickinson stove it is recommended that you bolt it
down using the 4 holes provided (2 on the bottom of each leg). The rear bolt
holes can be hard to reach so instead you can use the tie down bar (provided)
instead. Firstly mark where your stove is going to be located. Then screw
down the tiedown bar so that it allows your heater to slide with the feet
sliding underneath the upraised ends. Ensure that the tie down bar contacts
the stove somewhere between the middle and rear of the stove. Once in
place secure the front of your stove through the bolt holes. The tie down bar
alone will not secure your stove. It only prevents upward movement such as
tilting. If not secured otherwise, your stove will be at risk of sliding in high
seas.

6. Fuel System Installation
For efficient and safe operation of the stove, follow all recommendations for
properly installing the fuel system.
DANGER: Never use gasoline in the stove. Use only #2 diesel, #1 stove oil
or kerosene. The valves are factory calibrated to #2 diesel; if #1stove oil or
kerosene is preferred, the valves can be re-calibrated to suit those viscosities.
*** If in colder temperatures it may be wise to burn kerosene or add fuel
additives to your fuel to keep the fuel viscosity thin for correct operation. In
some cases, a valve with a higher flow rate may be needed.
Fuel Supply & Overflow Feature
The fuel supply fitting on the oil metering valve is a 3/8” (10mm) flare
fitting and the overflow is a 1/4” (6mm) flare fitting. To make these
connections you will need a flaring tool to connect the 3/8” flare nut as well
as a 1/4” flare nut. ACR (refrigeration) copper tubing should be used for the
first 3 feet of fuel line from the stove. Approved hose can be used for the
remainder of the installation. Run the fuel lines as straight as possible to
avoid air locks. Check all connections for any leaks.
The overflow safety feature is designed to allow the controlled escape of
fuel from the stove in case of over pressurization. If dirt, debris, or too much
pressure gets into the needle and seat inside the valve, the fuel will rise and
overflow out of the valve and away from the stove. It is common to get a
few drips now and then from the movement in rough waters, however, more
then a few drops of fuel from the overflow indicates the need to service and
clean the valve.
Under NO circumstances plug the overflow fitting!! A fuel line must be
taken from the overflow fitting back to the main tank if the fuel is supplied
from the main tank. If the fuel is supplied from a day tank, then run the
overflow line to a container away from the heat source. The fuel overflow is
a gravity escape. Do not install the overflow line so that is goes up or in
loops as this will cause an air lock and block the fuel from escaping. Plastic,
rubber or copper tubing may be used for the overflow line.
Note: If the your fuel tank vent or fill tube is higher than the valve of the
stove, and the overflow of the stove goes back to the main tank, there may
be a chance when re-filling that the fuel will back flow up the overflow and

www.dickinsonmarine.com ~ [e-mail]
Form#7.2-248 Issue#2
14
out of the valve. For this reason a manual shut-off will need to be teed in the
overflow line and closed when refilling tanks. CAUTION: After refilling,
you will need to burn off the fuel in the line before re-opening the shut-off
valve. Do not use a check valve. Remember to re-open the shut-off valve on
the overflow line.
Fuel Filter & Manual Shut-off’s
The fuel must be filtered before the fuel pump and before the oil metering
valve to prevent dirt and debris from plugging up the check valves in the
pump and the needle and seat in the valve. There also must be a manual
shut-off by the tank and also close to the stove as the pressure on the needle
in the valve will wear it out faster. We can supply a ¼” NPT fuel filter with
a shut-off for close to your stove for this purpose. (Part# 20-010) The 15
micron stone element in the filter (part#20-020) should be replaced every 1-
2 years.
Fuel Supply
The fuel can be supplied to your stove by either your main tank or a day tank
and fed with either a fuel pump or gravity depending on your install.
Gravity Feed
When using a gravity tank, there should be a minimum head of 12" (30.48
cm) above the fuel level marked on the side of the oil-metering valve to
operate correctly. The gravity feed tank must be vented and all fuel lines
must be as straight as possible to avoid air locks. Do NOT use a pressurized
tank.
The oil metering valve is rated to an incoming fuel pressure of 3 psi. If the
pressure exceeds 4 psi, a pressure regulator will be needed in the supply line.
(Part # 20-003) If installing a gravity tank larger then 30gal or higher than 8
feet above the valve of the stove, you will also need a pressure regulator.
Fuel Pump
When a low pressure fuel pump is used, a fuel line must be tee’d in as close
to the fuel tank as possible, not from the engine supply line or engine filter.
Use a check valve in the stove fuel line to stop the engine from pulling back
the fuel and starving the stove.

7. Walbro Fuel Pump Installation
When installing a Walbro fuel pump you must ensure it is mounted
approximately at the level of the valve on the stove. These pumps can “pull”
fuel but have trouble “pushing” fuel so it must be gravity fed from the pump
to the stove. The lift and the climate will then indicate if you need the
standard pump (part#20-000) or the heavy duty pump (part#20-002). We
highly recommend the heavy duty pump for all installs so you have the
option of adjusting the pressure if needed.
The standard pump Walbro’s FRD-2 part# 20-000 is a 12v DC pump with a
pressure of 3psi. It is for a standard installation where the climate is fair and
fuel run from the fuel supply to the pump is less then approx. 4ft vertical and
15ft horizontal.
The heavy duty pump part# 20-002 is Walbro’s FRD-2 12v DC pump with a
factory retrofitted pressure spring and an adjustable pressure regulator
installed for a higher pressure pump for a stove installation in a colder
climate and where the fuel run from the fuel supply to the pump is higher
then approx. 4ft vertical and 15ft horizontal. This pressure regulator will
adjust the pressure higher or lower to the oil metering valve.
*If using the heavy duty fuel pump part# 20-002, the adjustable pressure
regulator attached has a thread size of 1/8” NPT. It is soft die cast aluminum
so use caution when connecting the fittings. The numbered settings are only
for reference because depending on the fuel supply installation and the
climate will depend on the pressure of each setting. Disconnect the fuel line
at the valve and allow the pump to push the air out of the fuel line to see a
constant flow of fuel going into a bucket. Set the regulator to the lowest
setting. Watch the flow of fuel. Adjust the regulator setting until there is a
constant flow of fuel pouring into the bucket. If you have adjusted the
regulator to the highest setting with still no constant flow of fuel, the
regulator can be adjusted. Pierce a hole in the sticker on the center of the
knob with a 5/64
th
Allen wrench and turn the adjusting screw clockwise ½ a
turn.
To prime the pump, pump fuel into a container to remove all the air in the
fuel lines. After a cup of fuel has been pumped, reconnect fuel line to the
valve. If there is no fuel getting to the pump or there’s air in the fuel line the
pump can make a chattering noise.

www.dickinsonmarine.com ~ [e-mail]
Form#7.2-248 Issue#2
16
Once the valve is full of fuel and the pressure has been reached the fuel
pump will still continue to tick, but less frequent. Once the pressure drops in
the valve the pump will then begin to tick more frequent depending on the
demand of fuel from the valve. To lessen the noise of the pump pulsing, a
rubber backing can be installed.
The pump should be included in a control circuit with a 2 amp fuse so it can
be turned off when the heater is not in use. NOTE: If the power to the pump
is shut off, the fuel could still flow through to the pump by way of siphon.
The flow of fuel should be turned off using the shut-off valve near the stove
as well as the oil metering valve.
The pumps can be installed with fuel inlets and outlets up or down, however
mounting the pump with the fuel inlet (spout looking side) on top will give
the pump extra pressure and is easier to clean. The pump will need to be
primed the first time only to remove air in the fuel line. There are 3 check
valves in the pump to prevent the back flow of fuel, so the pump should stay
primed. If the pump does not stay primed then 1 of the check valves in the
pump needs to be cleaned
The pump should be installed in a ventilated area and not near a hot exhaust.
Connect the ground to a negative battery. This pump is not recommended for
gasoline.
Walbro FRD-2 Fuel Pump Upgrade
To upgrade a Walbro FRD-2 (part#20-000) to a Heavty Duty pump
(part#20-002) a factory spring & regulator must be installed. If you find you
are not getting fuel to the valve with the FRD-2 standard pump you may
need the stronger pump with the stronger pressure. Please contact Dickinson
to order a stronger spring & regulator. [email protected]
Once you have received a stronger spring and regulator from Dickinson, you
can upgrade your pump to a stronger pressure. Unscrew the 3 torx screws (t-
20) and with twisting the lid back and forth, pull it straight back off. Note
the pump plunger, spring, check valve, and a very small amount of fuel will
drop out if installed as per diagram. Place the check valve as shown in the
diagram on top of the heavier replacement spring, and the spring on top of
the pump plunger and push it back into the pump body holding it in with a
finger. Note the magnetic part of the plunger is on the opposite end of the

www.dickinsonmarine.com ~ [e-mail]
Form#7.2-248 Issue#2
17
spring. Replace the lid with the gasket on by lowering your finger on to the
red O ring sleeve without the plunger falling out (the plunger is about 2”
long so you have room to lower your finger out of the way). The red O ring
sleeve will fit inside the pump tube and the black O ring will fit over the
outside of the pump tube and will require twisting and pushing the lid
straight back in. This is a little tight but that is what makes the seal. Rotate
the gasket and replace the screws.
Now that your standard pump is upgraded to a heavy duty pump it must be
primed. When priming the heavy duty pump hold down the knob of the
pressure regulator to prime the fuel lines to take out the air. Then turn the
dial to the lowest setting on the regulator and increase the pressure one
increment at a time until the pump is just delivering a constant flow at the
heater.

8. Draft Assist Fan Installation
The 12v draft assist is not needed for operation but highly recommended as
it will help to vaporize the fuel and give more control in burning the stove as
clean as possible. The fan is a 12v DC fan that the draw is .17amp. The fan
is 12v and if 24v or 32v is needed, resistors are available. This fan is rated
for 8000 hours and is only for start up and for higher temperature settings as
using the fan all the time will burn it out prematurely and make hard carbon
deposits inside your burner pot clogging up the air holes causing the stove to
not operate correctly.
When turning the fan on, turn it up to a faster speed first, then you can adjust
it back down to a slower speed as this gets the fan blade going.
Whenever possible, ensure a weatherproof connection between wires with
solder or the appropriate connectors with 18awg wire. The motor mount
‘bushing’ washers should be placed in between the mount bracket and the
main housing NOT between the mount bracket and the head of the fastener.

During start up, operating at higher settings or during windy conditions, you
want to use the combustion assist fan on your heater to artificially boost the
draft. Your heater should operate without the use of the fan on lower
temperature settings. Some heater installations with only the minimum flue
heights or with flue elbows that inhibit the draft may need the use of the fan
more often.

9. Optional Hot Water Coil Installation
A hot water coil can be added to also enjoy water heating from your
Dickinson diesel stove. You can either order your heater with one already
installed in the stove or you can install the coil later yourself. Hot water coils
are made of 5/8” OD stainless steel tubing and are available in a 1 turn coil
for all model stoves to heat approx. 5-10 gallons of water. Hot water coils
are also available in 2 turn coils all models except the Bristol to heat approx.
15-20 gallons of water. To plumb the hot water to the stove, ½” copper
tubing should be used with the compression fittings provided.
The coil in a stove can be used to heat the water in your existing hot water
supply tank. If the tank is mounted above the lower coil, the water will
circulate on its own from the tank into the hot coils and rise back into the
tank by convection. If not, the water will need to be circulated by a low
volume water pump. The temperature of the water will change depending on
the speed of which it’s circulating and the operating settings on the stove.
It takes approx. 3000 btu’s to raise 10 gallons of water to 30 degrees in 1
hour. Most of the btu’s that the stove produces is dissipated as radiant heat
and is expelled through the chimney. Therefore, only a general guideline as
to water heater capability can be set.
WARNING: A pressure relief valve must be present or dangerous pressure
buildup will occur.

It is best to order the stove with the coil already installed but follow these
instructions for replacing or installing a new coil.
1. Remove the 6 screws that hold the top down onto the stove and remove
the cast iron top. Save the 6 fastener clips that receive the screws underneath
the stove top. Then plug the burner so debris won’t clog your fuel lines.
2. Remove any old sealant away from the stove walls and underside of the
cast iron top.

3. Punch 2 holes at 5/8
th
in diameter in the back of the combustion chamber.
Your stove may have punch-outs in the back wall of the stove for the coil. If
so, remove them. Use a 5/8” drill bit and drill out the cement from the back
of the stove where the coil holes are.
4. Remove the firebrick to get the coil in. Do not be too concerned with the
appearance of your firebrick but if it is crumbled it’s time for a new one.
Install the coil so the ends of the coil stick 2” from the back of the stove.
5. Drill a hole and position the bracket that was included with the coil, to
hold the coil in place with a 1/8
th
drill bit. Use the #10 x 1 1/4" screw to
screw down the 'L' shaped bracket. Clamp down the coil between the two
bracket pieces. This bracket keeps the coil in place. It is important that the
coil be installed so there is a constant rise in the tube as it goes to the
back of the stove. This aids in the movement of the water or glycol.
6. Paste cement or hybond sealant around the coil ends as they exit the stove.
If you are using cement then mix with water. It is not too important to get
the consistency exact but oatmeal is a good consistency to aim for.
Also, cement around the firebrick supports. The cement or sealant will need
24 hours to dry completely.
7. Use the left over cement or hybond sealant to repair any cracks or missing
portions of the insoline cement liner as the combustion chamber needs to be
air tight for the stove to work correctly.
8. Re-position the fasteners clips so they will receive the screws when
screwing down the cast iron top to the stove walls. You will need 6 stainless
or galvanized #10 ¾ flat head screws.
9. Apply a generous amount of hybond sealant to the top of the stove walls
and over the fastener clips.
10. Re-place the cast iron top and screw down into the fasteners. Use the
remaining hybond sealant to fill in any cracks between the top and the stove.
The combustion chamber needs to be air tight for the stove to work
correctly.
