$350 or $400 or more depending on the BTU or gas type

[Dan Webster]

one more thing... these heaters cant be converted from one gas to another without it costing plenty so if you are buying a heater like this you need to know exactly which gas you are gonna have and make sure the heater is compatible.

Thanks again, that's a good thing to know and keep in mind!!!!

This heater is unvented and uses the ODS, (oxygen depletion system), pilot. Only needs a gas line to hookup and operate.

Three postion gas valve, Off/Lo/Hi, 0/15000/30000btu - No t-stat.

What does ODS mean?
An unvented gas heater will consume oxygen and give out its exhaused gas in that room.
Don't think that it is safe/legal to use unvented gas heater in an "air-tighted" and well-insulated house in US and Canada!?

[Dan Webster]

ODS means( oxygen depletion system) when oxygen is thin in the room the ods reduces the pilot flame and the safety magnet cuts off the gas and the heater is turned off, this keeps ya from dying from no oxygen. now , how well does it work? some say its ok others have doubts . my opinion this is a fine heater

Thanks for the explanation.

It still gives out combustion exhausted air which is mainly composed of carbon dioxide. If the combustion is poor, carbon monoxide will be generated and this is extremely dangerous. I think that it is not recommended to use unvented heaters in houses at all in Canada.

It isn't recommended to use un-vented fuel-burning heaters back here in northern Europe either, no matter what fuel... houses are quite tight. But, the ODS should shut the heater down before O2 will be depleted so that CO will form. If it is a catalytic heater, it should produce mainly CO2 on quite low oxygen. Some NOx of intake air will be used in the process too.

Don't remember where I read this, but some fire extinguishing gas mixture was designed to lower the O2 content of air down to some 11%... barely enough for human life for a short while, but non-catalyzed burning of most carbon compounds would require 16%... correct me if you find correct percentages somewhere.

You could be very well correct on it not being legal to sale an unvented gas heater in some states in the US, (California , being one of them -- Johnstone Supply Co. has some unvented gas heaters listed in their book and it says:

"Suitability for installation in your area should be verified with the local code authority. These products are not approved for use or sale in all or part of the following states: Alaska, California, Colorado, Massachusetts, Minnesota, Montana, New York and Utah.")

(Bows deeply) Please pardon my intrusion, Great Masters. I believe I may be able to offer some small bit of enlightenment on this subject.


These are the halon extinguishers. Humans can survive in a halon atmosphere long enough to exit a building, but not much more. They were initially designed as a stop gap type system to be installed in older movie, and theater houses, with inadiquate exits to bring them up to modern day building, and safety codes. Fortunatly they were never approved for that reason. They are however installed in many museums, art galleries, libraries, and other buildings that house important documents. Were it not for the halon systems the documents would be destroyed by the water, or even the Co2 units in use prior to halon.

Hope this helps.

Humbly offered to those who would accept my paltry tidbits of wisdom.

Information humbly accepted.

That's just what I tried to remember.

I no longer (unfortunately) have my old Kenmore appliances, so I have no number to go by. 

It is time to yet again replace a Kenmore appliance (washing machine, not quite 6 years old...fridge is already in a landfill somewhere--didn't make it to 6 years)

Does anybody by chance know who built their appliances prior to say, oh about 1986 (when they were still good)?  I know that Kelvinator used to manufacture their refrigerators, but my knowledge ends there.

Any help would be appreciated.

Good chance the washing machine was Whirlpool. Washing machines were the beginning of the Sears/Whirlpool courtship way back when...

Thanks for your reply.  Whirlpool...oh geez.  Trouble in paradise is right!
