DICKINSON MARINE PROPANE COZY CABIN HEATER
Keep your proof of purchase and product serial number for warranty
INTRODUCTION
Thank you for selecting the Dickinson Marine Cozy Cabin Heater. Your unit was
carefully inspected and tested at our factory. We take pride in producing one of the finest
heaters manufactured for marine use.
Because of the continuing refinement of our product designs, your heater may possess
features that are not discussed in this manual. We have tried to supply all the information
you might need, so please take time to read this manual before installing and using your
Cozy Cabin Heater.
Dickinson Marine advises strongly against unauthorized modification of this product, but
we do encourage you to correct problems which may arise by undertaking the simple
repairs and maintenance described in this manual.
The most important reason to carefully read this manual is that many of its instructions
are essential to the safe operation of your Cozy Cabin Heater.
Any recommendation or advice by Dickinson Marine, or any of its employees, is
given with the understanding that it is solely as an accommodation to the customer,
and should not be relied upon by the customer without an independent verification
of its applicability to the customer’s particular situation.
SAFETY AND INSTALLATION
General
The Cozy Cabin Heater, Model 10000, is designed to be fuelled only by propane (LPG).
If compressed natural gas (CNG) is used in this heater the burner flame will be
inadequate for heating.
Propane is an excellent and convenient fuel if used in accordance with rules, safety and
common sense. If these rules are ignored, there is a danger of fire and explosion. We
have done our best to design and construct your Cozy Cabin Heater with safety in mind.
You can do your part by following these rules.
Installation of Heater in Cabin
Choose a convenient location for optimum air circulation, but not where someone may
accidentally touch it.
The best height is such that the top is approximately 36” off the floor in a boat with 72”

headroom. It is better to be closer to the ground whenever possible. Allow a safe distance
between the sides and the bottom of the heater and combustible materials. Usually 6” is
sufficient, but if in doubt, protect combustible material with metal and/or insulating type
material such as ceramic tile. It is the responsibility of the installer and the operator to
ensure that the temperatures of surrounding materials does not get too high.
If the heater is mounted such that the stack length or clearance of combustible material
above the heater is less than 24”, the overhead surface should be protected with metal
and/or insulating type material, such as ceramic tile.
Place the insulating washers between the feet of the heater and the mounting surface. This
is all the protection necessary on normal bulkheads. However, if the bulkhead is painted
or is soft vinyl, a stainless steel sheet larger than the area covered by the heater should be
installed. This would create further protection from heat discoloration. Hard insulation
material behind the stainless steel sheet would also be recommended. Screw heater in
place temporarily. (It will be necessary to remove it to install the stack.)
Installation of Deck Cap and Stack
** You must exhaust the heater to the exterior to avoid carbon monoxide poisoning!
Diagram 1
Drill a 2” (5.08cm) diameter hole in the cabin for the stack to pass through.
a) Note: Stack is not supplied in this kit as every installation is different.
There is no need to ship 6’ if you need only 2’ of stack. The flue material
is 1” (2.54cm) OD (outer diameter) ornamental stainless steel tubing
available from your dealer, boat builder, boat yard and some chandleries. It
is the same pipe used to make pulpits and railings (1” OD = 7/8” ID-inside
diameter). If you are bending your stack, remember to take into account
the radius of your bend in determining the overall length. Do NOT bend
more than 45°at any one bend.

Form#7.2-70 Issue#2
2. If your deck is not a flat surface where you want to install the exhaust cap,
fabricate a round wooden ring approximately 1/2 to 3/4 inches thick with a 2”
hole drilled through the middle on which to mount the deck cap. Mill the
underside of the pad to match the contour or angle of your deck. The top side of
the pad will then be a level surface for the flange of the exhaust cap. A teak winch
pad is ideal, and available from local marine dealers.
3. Using a suitable bedding compound, screw the deck cap (and wooden ring if used)
in place. Use the supplied gasket between the cap and the ring or deck.
4. Determine the length of the pipe required by measuring the distance between the
top of the heater and up into the deck cap. The pipe may be bent up to a 45°angle
with a 5” radius or more to by-pass deck beams or other obstructions (an
electrician’s conduit bender does a good job). You can easily make a mock-up
using residential copper pipe before you bend the real thing.
5. The maximum recommended length of stack is 10’ (3.05m). If there are bends in
the stack, remove 18” (46cm) from the maximum length for every bend.
6. Cut the stack to proper length, remove the heater, place the stack up into the
exhaust cap. Ensure the stack is butted up against the top of the inside of the cap
to form a complete seal. Install interior finishing ring ensuring that the stack does
not contact the ring.
7. Replace the heater and fasten it permanently, remembering to reinstall the
protective washers between the feet of the heater and the mounting surface.
8. The New Deck Cap (Nov 2006) has an adjustable vent cap. This cap can be
threaded down to close off the stack when the heater is not in use or if the boat is
in heavy weather and you wish to close the exhaust. Ensure that the vent is
open before using the heater. Using the heater when the vent cap is closed
could result in serious injury.
Propane (LPG) Fuel System
1. Buy your cylinder, gauge, master solenoid valve and hose from a reputable marine
dealer, or your local LPG service center.
a) We specifically recommend that only a high quality regulator be used with
your Dickinson Marine Cozy Cabin Heater. It must be set at 11” water
column. (In Europe this is sometimes expressed as .0274bar and is close to
.5psi).

www.dickinsonmarine.com ~ [email protected]
Form#7.2-70 Issue#2
2. Locate the cylinder and regulator in a locker vented to the open air (preferably on
the deck or cabin top) isolated from the hull interior by a vapor tight enclosure.
Refer to local codes or Coast Guard requirements for details.
3. Propane is heavier than air. Therefore, the locker in which the cylinder is
installed must be vented at the bottom. Position the vent above the water line, and
at least two feet from any hull opening to the boat interior or engine exhaust.
We recommend the installation of a vapor monitor on your boat with all propane fueled
devices.
4. Propane is a two-phase (liquid/vapor) fuel, and only vapor withdrawal from the
tank is safe. Firmly mount the cylinder, right side up, to ensure that liquid
withdrawal does not occur.
We recommend that a solenoid valve, which can be controlled by a switch located in your
cabin, be installed next to the manual cylinder valve. The cylinder valve outlet and the 12
VDC solenoid valve should be clean and dry when they are connected to each other.
5. Use Teflon tape or Loctite to seal these connections being very careful to not
introduce any foreign materials into the system that can plug the tiny appliance
orifices.
6. A 0-300 psi (0-20 bar) pressure gauge may be installed between the bottle and the
regulator to give bottle pressure.
7. Install the regulator downstream from the pressure gauge with its vent port
pointing downward, which prevents the pressure vent from getting plugged.
** In some cases the solenoid valve is installed on the low pressure side of the
system (i.e. after the LPG regulator). See solenoid manufacturers' instructions
for proper installation.

Form#7.2-70 Issue#2
Recommended LPG System Installation
8. Starting from the propane tank itself, the fuel line attachments should occupy the
following positions: (a) the tank shut-off valve, (b) the pressure gauge, (c) the
regulator, (d) the solenoid valve.
9. Affix the caution label plate supplied with your Cozy Cabin Heater in the
immediate vicinity of the gas cylinder in a place where it will be plainly visible.
10. The LPG supply line should be 3/8” (10mm) soft copper line, on which your
plumber will install the flare nuts when you tell him how long to make it. It can
also be a flexible fire-resistant hose, UL or CGA approved hose for use with
propane, complete with 3/8” (10mm) flare nuts on each end. A single continuous
line or hose without couplings or tees is a must. Every connection is a potential
leak.
11. Because every connection is a potential leak, the fuel line should be one
continuous length of hose or tubing. Do not make a “T” off and fuel line between
an existing appliance and the gas cylinder to feed another appliance. (You may
install a “T” connection only within the fuel tank’s enclosure, so any leakage is
dissipated overboard)
12. Be sure you do not kink the hose or piping connecting the regulator with the
heater by bending it too sharply during installation.
13. Protect the hose against vibration and damage by securing it tightly to bulkheads
and hull side with non-corrosive ties or clamps which will not cut, abrade or pinch
it.
14. Fuel lines must be protected by close-fitting grommets and sealants where they
pass through decks or bulkheads, and the passage must be made vapor-tight. They
should be installed so that they are readily accessible to inspection.
Fuel System Testing
If you install a low pressure Guage (0 to 15 PSI) after the pressure regulator you can
check for leaks by watching the pressure guage. To do this open the manual cylinder and
solenoid valves and make a note of the reading on the pressure gauge. Now close the
manual cylinder valve. The pressure should remain constant for at least 10 minutes. If it
does not, gas is leaking out of the system.
The leak(s) should be located by applying a mixture of liquid detergent and water to all
connections and other suspect points and checking for bubbles.

Form#7.2-70 Issue#2
Do not attempt to locate leaks by using an open flame. Repair and re-test the system
before putting it into operation.

please refer to the American Boat and Yacht Council’s pamphlets #A-1 and #A-22
respectively. These pamphlets may be ordered directly from A.B.Y.C.
OPERATING INSTRUCTIONS
1. The first time you use your heater you will have to purge the air out of the supply
lines before it will light. Turn the knob to the “pilot” position and push in. You
may hear a hissing sound. Keep the knob pushed in until you smell gas, then
immediately turn the knob to the “OFF” position. Wait a few moments before
lighting to allow any excess propane to dissipate. Purging air can take quite a
while if you have a long supply line. This is only necessary when fuel supply is
disconnected.
2. Do not forget to remove any plastic before using.
3. Push control knob in, hold it in and turn counter-clockwise to pilot position. If this
is the first time or the first time in a while that the heater is being used, push in the
knob on the pilot setting for 60 second or until you smell gas. This will purge the
pilot light parts of air. Then, with the knob depressed on pilot, push in the black
spark-ignition button to ignite pilot. Once ignited, hold control knob in for 10 to
20 seconds. If it does not light, repeat this procedure. If it still does not light,
purge the line some more or hold match over pilot.
4. When the oxygen depletion pilot flame comes on, you must hold the knob in for
10 to 20 seconds. During this time the pilot flame heats up the thermocouple.
When the thermocouple is hot it generates a small amount of voltage, which will
energize a small solenoid coil inside the gas valve. This energized coil permits the
valve to regulate propane into the burner.
5. Adjust the burner by turning counter-clockwise to Low. To extinguish, turn the
knob all the way clockwise to Off.
Caution: This heater consumes oxygen. You must supply sufficient outside
air to replace the oxygen used by the heater. This unit is equipped with an
oxygen depletion device which will turn off the pilot flame when the oxygen
level drops to 95% of normal. This, in turn, cools off the thermocouple,
which shuts off the main valve.

TROUBLESHOOTING
Contact Dickinson Marine directly, or consult your dealer, if the following suggestions do
not resolve the difficulty.
Gas Smell
1. Extinguish all open flames and smoking materials, close both manual and solenoid
cylinder valves immediately. Make sure that the appliance valve is closed.
2. Ventilate all interior compartments thoroughly. Maintaining as much ventilation as
possible, open cylinder valves. Make sure that the appliance valve is still closed.
Apply a mixture of liquid detergent and water to all connections, checking for bubbles
indicating a leak. Do not use a flame to check for leaks.
3. When repair of the leak(s) has been completed, test the system with the aid of the
pressure gauge.
Inadequate Heat - Flame Burning Low or Gas Out
1. Your system may be low on fuel - check your tank pressure gauge.
2. The gas cylinder valve may not be fully open - make sure the handle is turned as far as
it will go in the counter-clockwise direction.
3. The burner orifice may be obstructed. Let the burner cool, then remove the 4 machine
screws (2 each side) which secure the burner and valve assembly to the heater body.
Remove burner assembly, take off the burner cap, and remove the orifice ( you will
require a long 7mm or 9/32” socket or nut driver). Clean out the orifice and reinstall
the part.
4. LPG gas will not flow as readily if the outside temperature is very low, ie. below
freezing. There is not much you can do about this condition until the propane
cylinder locker warms up.
5. Ignition System Fails to Spark
Check that the ignition lead is connected to the spark plug.
Inspect the ignition lead from the valve to the spark plug, ensuring that the lead is not
shorting out before reaching the spark plug.
Clean the spark plug electrode to ensure a strong spark is evident. Brass wool or light
grit sandpaper work well.

Form#7.2-70 Issue#2
Burner Does not Stay Lit
1. Check to make sure the pilot is still on. If it has been accidentally extinguished,
voltage will no longer be generated, and the valve will have snapped back to the
closed position by the stainless steel spring.
2. There could be a problem with the thermocouple. The small bulb-like attachment
protruding into the pilot flame is one end of the thermocouple.
3. Check first that the thermocouple is screwed into the valve tightly enough. A loose
connection will not transfer the 1.5 millivolt. If it has been tightened too much, the
insulating washer will have been crushed, shorting out the thermocouple, and so will
not generate the 1.5 millivolt. It must, therefore, be replaced.
4. Heaters are tested at the factory and thermocouple failure problems should be very,
very rare. If necessary, however, remove the valve end of the thermocouple from the
valve as described on the following page. Lightly sand the end which has been
removed from the valve with very fine sandpaper. Replace in the valve and test. If
this does not work, the thermocouple must have failed and will have to be replaced
5. The electromagnet (solenoid) inside the valve may have failed and will have to be
replaced.
PILOT - THERMOCOUPLE ASSEMBLY
Replacing the Thermocouple
Tools Required
1- Phillips screwdriver
1- Flat screwdriver
1- 5/16”(8mm) open wrench or small crescent wrench
1- 3/8”(10mm) open wrench
1- 1/2”(12mm) open wrench
1- 5/8”(16mm) open wrench
1- 3/4”(19mm) open wrench
General Information
1. Thermocouples are made out of two dissimilar metals. One end of each metal is
fastened together. When this connection is heated up, a small amount of electricity is
created (1.5 millivolt) and can be measured between the other two ends of these wires.
2. The outside of the thermocouple is a copper tube, which acts as a conductor and the
inside is an insulated nickel wire, which at the other end, is separated from the copper
wire by a very small insulating washer. This end of the thermocouple screws into the gas
valve, which contains an electromagnet(solenoid).

www.dickinsonmarine.com ~ [email protected]
Form#7.2-70 Issue#2
3. When the thermocouple is heated, the electricity generated attracts the electromagnet in
the valve and holds the valve open. If the flame is accidentally extinguished, the
thermocouple cools, causing the electromagnet to spring back and closes the valve,
therefore, no flow of gas.
4. If the thermocouple is not holding the valve open, check first that it is screwed into the
valve tightly enough, as a loose connection will not transfer the 1.5 millivolt. If it has
been tightened too much, the insulating washer will be crushed, shorting out the
thermocouple, and so it will not generate the 1.5 millivolt, and must therefore be
replaced.
Replacement Instructions
1. Turn off the gas supply. Remove the main gas supply line to the heater. using 2
wrenches (5/8” & 3/4”, or 16mm & 19mm). Take the heater off the bulkhead.
2. Loosen the 1/2” (13mm) compression nut on the valve which connects the copper line
leading to the pilot flame assembly. Remove line from valve.
3. Remove the 2 phillips screws on the outside of the heater which hold the pilot
assembly.
4. Now carefully pull out the pilot flame assembly so that you can undo the screws
which hold the thermocouple in place. Remove the other end of the thermocouple
from the valve (5/16”, 8mm, crescent wrench), and you have the thermocouple out.
5. Replace the thermocouple, reversing the above procedure, but being extremely careful
when you first put the end of the thermocouple into the valve. If you tighten too
much, you will crush the insulating washer and need another new thermocouple.
Finger tight plus a 1/4 turn with a wrench is enough. When replacing the
compression fitting on the pilot fuel line, tighten firmly with the wrench. Be careful
not to over-tighten.
6. Once your heater is completely reassembled and connected, mix some liquid soap and
water and perform the standard test for leaks with your fuel system. Test in a well
ventilated area, with no open flames.
To Replace the Electromagnet (Solenoid)
When you remove the thermocouple from the control valve, remove the larger nut with a
9/16” (14mm) wrench. The electromagnet should fall out - if not, push the valve stem
where the knob should be and it will come out easily. Install the new electromagnet, with
the spring end first. Replace the nut, and re-install the thermocouple back into the control
valve.
