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
- 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.
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
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.
does this SunStar Corcho
Model CK18 heater work again?
(Applies to Manual ONLY) Its
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.
doesnt 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.
these heaters be installed
in bedrooms or bathrooms? Only
the model CK-6 (rated at 6,000
Btus) can be installed in a bathroom. Both the CK-6
and the CK-10 (rated at 9,500
Btus) 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 Btus or less in
bedrooms and 6,000 Btus
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.
this heater be installed in mobile homes? Yes,
this heater may be installed
in whats 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 dealers
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.
