■ The heater and its individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of U PSI (3.5kPa) ■ The heater must be isolated from the gas supply piping system by closing its individual manual shut-off valve during any pressure testing of the gas supply piping system in equal or less than U PSI (3.5 kPa) ■ The LP gas supply cylinder to be used MUST be constructed and marked in accordance with the specifications for LP gas cylinders, U.S. Department of Transportation (DOT) or the standard for cylinders,...

About a Direct Draft Propane Heater This direct vent propane heater fireplace is a clean burning low pressure (11”/WC) propane appliance for use on board small marine vessels and many other different applications. These heaters are equipped with a flexible stainless double walled vent pipe and a combination 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 isolated...

Heater Specs Mounting Backplate

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. • If not connecting your heater using one of Dickinson’s propane hoses then you will need to find fittings to match the heaters. The valve on the heater has a male 3/8” flare fitting SAE, 45° flare standard gas fitting. • Install a separate low pressure regulator that reduces pressure to 11” W/C When installing your new propane heater, keep in mind the location...

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 cement board with a metal liner, a .5” standoff is best for air movement behind. Another alternative is using insulation or cement board 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. Cutting the Chimney Pipe We DO NOT recommend...

Horizontal Flue Exit We recommend the flue be as straight as possible but also we recognize that in some installations it may be necessary to vent out of a wall. In these cases you would need to follow a specific method to ensure the draft does not slow down to the point it affects the heater. To exit out of a wall you would need to ensure the bend is made with the entire 28" length of pipe as this will ensure a gradual slope rather than a severe bend. The bend must start at the top of the heater and end where the pipe exits the wall. It will be necessary to place the spacer springs - located...
