WARNINGS
- This is a low pressure appliance and MUST have a separate low pressure
regulator installed or operation can result in a dangerous fire or extreme
internal damage to your heater.
- Improper use of a gas appliance can result in serious injury, fire, explosion,
carbon monoxide poisoning, oxygen depletion or even death.
- Do not operate this heater unattended.
- Turn off the heater when refueling.
- This propane heater requires an installed chimney for correct operation. Do
not attempt to operate the heater without the supplied flue chimney installed
correctly as required in this manual.
- Do not store or use gasoline or other flammable vapors or liquids in the
vicinity of this appliance.
- Do not install this appliance in spaces containing internal combustion
engines, fuel tanks, or joints and fittings of their fuel systems.
- All installations must conform with local codes or in the absence of any
codes with the current National Fuel Gas Code, ANSI Z223.1 or current
CAN/CGA B149, Installation Codes.
- Manufactured or mobile home installation must conform to Manufactured
Home Construction and Safety Standard, Title 24 CFR, Part 3280, or, when
not applicable, the Standard for Fire Safety Criteria for Manufactured Home
Installation Sites and Communities, ANSI/NFPA 501A,(USA) or Mobile
Homes Standard, CAN/CSA-Z240 MH Series, in Canada.
- Follow ALL installation and operation procedures.

1. About a Direct Draft Propane Heater
This direct vent propane heater fireplace is a clean burning low pressure
propane appliance for use on board small marine vessels and many other
different applications.
These heaters are equipped with a stainless double walled vent pipe and
deckfitting/ exhaust cap. Fresh air is pulled from outside, through the outer
pipe into the combustion chamber while exhaust gas leaves the vessel
through the inner pipe. The air from inside the cabin is not being used for
combustion so a fresh air vent is not needed. Since, this unit has an isolated
combustion, the exhaust gases are being taken out via the chimney so no
moisture is being created.
These heaters are equipped with a CGA/AGA approved safety gas valves. If
the flame should ever be extinguished the gas will be shut-off automatically.
Manual ignition involves lighting the heater with a long barbeque lighter
with the door open and therefore avoids any initial build up of unburned gas.
The installation of a gas detector is recommended for all LPG appliances.
*NOTE: When using the P12000 heater on high setting, the fan may have to
be used to draw out the heat from the chimney pipe to keep it from sooting
the window.
2. Important Notes
Here are some important notes to remember when installing a Dickinson
direct draft propane heater:
• Mounting & location, 12v power hook-up, minimum 20” and a
maximum 56” of chimney, the location of hole for the chimney & the
fuel supply.
• The fittings needed to connect to your fuel supply.
• Install of a separate low pressure regulator (11” WC).

3. Installing your Heater
Location
When installing your new propane heater, keep in mind the location of the
heater and where it will maximize the heating capability. This propane
heater is equipped with a 12v fan that will blow hot air from the top of the
heater down onto the floor.
This increases heating efficiency and provides good circulation of hot air.
Mounting the heater lower will allow for more efficient circulation of heat in
the cabin. Plan your heaters location prior to installing to ensure the location
chosen will fit the specifications and safety clearances.
Combustible material such as the deck/ceiling or walls that are closer to the
heater then the specified safety clearances must be insulated with insulation
or millboard with a metal liner, a .5” standoff is best for air movement
behind. Another alternative is using insulation or millboard and ceramic tile.
Mounting
Secure the heater mounting plate directly onto the mounting surface. No
additional insulation is required. Use appropriate fasteners for mounting.

Chimney Pipe
The stainless double walled flue pipe that is included with the heater is 28”
(71cm) long. Four springs are between the inside and outside pipe to ensure
that an even air space is provided. It is important that two springs be located
at any bend in order to prevent the pipes from touching.
Extensions are available in 10” (25.4cm) part# 19-005 and 28” (71cm) part#
19-000. The maximum total length of the flue exhaust pipe can be 56” only.
Locate your heater so the distance between the heater and the pipe conform
to the available pipe lengths.
We do not recommend you cut the pipe but the pipe can be cut with a fine
hacksaw blade to the required length. To do so, twist the pipe to tighten the
pipes flexibility, then tape the end of the pipe and install a hose clamp on the
side of the pipe that you are keeping. This is so the clamp is left on the pipe
and only removed after or during installing. Cut with fine tooth hack saw
blade then use a round file to remove the large burrs in the inside of the pipe.
Use caution as the flexible pipe can be easily damaged.
Locate and run the vent pipe such that no low points occur where water or
debris can accumulate and thus block the exhaust or intake. The direct vent
chimney is flexible and can be bent to provide any angle of offset. The
chimney pipe can also exit horizontally.
If you want a horizontal exit with the chimney pipe, the heater will work
satisfactory if the full length of the pipe supplied (28” / 71 cm) is used to
achieve the 90 degree angle. When making a bend in the chimney pipe,
make the bend gradual so you don’t have hot spots in the pipe when
operating. When bending the pipe, don’t have the bend go downwards as
this will affect the draft. See diagram below. Use caution with bending the
pipe to not collapse or damage it. If the pipe needs to be cut, use extra
caution so the pipe doesn’t unravel.
