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 combustion, the exhaust gases are being taken out via the chimney
so no moisture is being created.
These heaters are equipped with a certified safety gas valve. 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 operating on the higher settings, it is recommended to use
the fan on a low or medium speed in order to maximize the heat output of
the heater but also, to cool the air intake chimney and keep the flames from
creating soot. It is far better to save the propane and burn the heater on low
with little air blowing, than to burn the heater on high fire without the fan.
This will waste propane and heat up the chimney before all the heat can be
extracted from the heater. The fan only draws 0.2 amps, is 12 volts and can
be connected to a 115volts 500ma transformer.
