What is an ODS and
how does it work? The ODS is an oxygen
detection safety pilot system. It is designed to shut off the gas
supply to the heater if the oxygen content in the room drops to
18% from a normal 21%+. In this event the pilot flame actually
lifts off the thermocouple cooling it down and causing the gas
valve to close and the heater to shut off. Also, each ODS has a
tamper resistant pilot orifice assembly, so do not try to drill or
clean out the ODS pilot with a hard object as you will damage it.
Follow the cleaning instructions located below.
How do I clean the
ODS pilot assembly? If your pilot will
not stay lit, try cleaning it. Use a can of compressed air, such
as is used to clean a computer, to blow dust out of the pilot
assembly. Sometimes just blowing air back through the pilot will
get rid of the dirt.
If
that fails, turn off the gas supply to the heater. As indicated in
Figure 5 below grab nut A with an open -end wrench and loosen nut
B from the pilot tubing with another small adjustable wrench. Blow
air pressure through the holes as indicated. This should blow out
any foreign materials. To reassemble, tighten nut B by grabbing
nut A with the open-end wrench. WARNING: When the heater is
reassembled, always check for gas leaks. Apply a soap and water
solution to all joints and watch for bubbles to check for gas
leaks. Never use any open flame to check for gas leaks.
If that fails, you need
to remove the orifice from the pilot burner cartridge using your
wrenches to unscrew the orifice (Item A) and blow air through the
pilot burner as show in Figure 5. If the pilot burner remains
blocked you will need to use a soft brush (pipe cleaner will also
work) to dislodge a spider web or other obstruction. To prevent
damage to this assembly, follow the instructions below for
disassembly and assembly of the ODS for cleaning.
WARNING: Never use needles, wires, or similar cylindrical
objects to clean the pilot orifice. This will only damage the
calibrated pilot orifice (about the size of the head of a pin) which
controls the pilot gas flow. Simple rinsing with water and blowing
air over it should clean the orifice.
How does this SunStar
Corcho Model CK18 heater work again? (Applies to Manual
ONLY) It�s slightly different than some 3-plaque heaters you may
have seen previously. Instead of turning on the pilot and then
one, two, and three plaques, the SunStar Corcho Model CK18 uses
just two burner chambers and operates first on the single plaque
burner. After the single plaque comes on, the double plaque is
turned on � giving you three full plaques of operation. If only
two plaques are needed, then the double plaque burner may shut off
leaving just one plaque burning.
Can a SunStar
Corcho heater be converted to Natural or Propane Gas? No, each
heater is specifically designed to work on either Natural Gas or
Propane Gas. Each heater is certified only for use with the type
of gas indicated on the heater nameplate (data plate). It is not
designed for use with other gases and is not convertible to use
with other gases.
Why doesn�t it
need electricity? Each SunStar Corcho heater is equipped with
a thermocouple incorporated in the ODS assembly. This is also the
flame failure safety system. The heat from the pilot light warms
the thermocouple and the dissimilar metals in the thermocouple
react to the heat from the pilot flame and create a small amount
of electricity (e.g. millivolts of electricity). This electricity
from the heat is then used to energize a magnet in the gas valve
to open it against the tension created by a spring in the gas
valve. This allows gas to go to the burners. When the pilot flame
is extinguished and is no longer generating heat on the
thermocouple and, thereby, millivolts of electricity, the magnet
de-energizes and the spring shuts the valve off. This is designed
to turn off all the gas to the burner and pilot system. The use of
this safety system and the gas fuel are the reasons that no
electricity is needed to operate a SunStar Corcho heater. This
product will still provide heat to your home even during power
outages.
Can these heaters
be installed in bedrooms or bathrooms? Only the model CK-6
(rated at 6,000 Btu�s) can be installed in a bathroom. Both the
CK-6 and the CK-10 (rated at 9,500 Btu�s) can be installed in
bedrooms. All other models are too big. The National Fuel Gas Code
(NFPA 54) permits wall mounted installation of vent-free gas
heaters of 10,000 Btu�s or less in bedrooms and 6,000 Btu�s or
less in bathrooms. Please check with your gas supplier to
determine if installation of these heaters in bedrooms and
bathrooms are permissible by your state and local
codes.
Can this heater be
installed in mobile homes? Yes, this heater may be installed
in what�s termed "aftermarket" manufactured (mobile) homes where
it is not prohibited by state or local codes. An "aftermarket"
mobile home is defined as any type of mobile home that has already
been sold to an end user or homeowner. It cannot be installed in a
new mobile home on the dealer�s lot, before it has been sold, but
it can be installed in any mobile home after it has been sold
(e.g. aftermarket). When installing this heater in a mobile home,
the same safety rules of confined and unconfined spaces and
clearance to combustible materials should be
followed.
