WeatherKing Acclaim II

We changed from propane to natural gas, changed the jets and the system short cycles and doesn't blow hot air

    My Weatherking Acclaim II seems to hit or miss, it cycles short sometimes blows cool air and often will allow the temp get to 60 degrees. The setting is constant at 69 and no one is screwing with the thermostat, so we don't know what the problem is. We can hear it come on then just go off after a few mins. When we decide we have had enough we come on down turn it off and then back on and then it decides to work and heat up the house. Anyone know what is wrong with this furnace? Any ideas?

Not only the jets but you need to change the spring in the gas valve and cut the pressure WAY back to prolly 3.5"wc

It sounds like your compressor is either not running or is low on refrigerant. If it is low on refrigerant it means you have a refrigerant leak somewhere in the system. The leak would have to be found and repaired or the unit is going to keep leaking down every time you pay to have it recharged.

Hi im a plumber/gas fitter who has been asked if i can convert a wildcat 410 (a2) ser 1983 from lpg to ng which is currently in use at a crash repair spray booth is this possible?


Yes look up the gas valve part # and find the LP kit for that model number. It will come with new pilot orifice, new burner orifices and the springs to replace inside the gas valve. Remember that natural gas is .08"wc and LP is a heavier gas it needs to be set at 11"wc .You need a manometer to check the pressure before you light it again .Did you know that propane provides more energy per unit volume than natural gas. Heat is measured in BTUs, or British Thermal Units. Propane provides about 2500 BTUs for the same volume of natural gas that only gives 1000 BTUs.

Hi helpers, I'm an apprentice plumber and have a lot to do with rheem stellars, i replaced a thermocouple today on one and unit lit fine and pilot stayed on, however the customer rang and complained and...


Your not getting enough air mixing with the gas and that's what causes the black soot. Typically this occurs when you're using a natural gas system on propane or butane. If this is the case you need to convert it to the proper propane orifices (jets) and open the air intake. If the unit has not been converted the problem still remains the same, you're not getting enough air mixing with the gas. You have an obstruction, which can be very small, inside the air intake or mixing tube or the orifice has been opened up to large and is allowing too much gas into the system and the maximum air opening isn't enough to compensate for the extra gas. Cobwebs are a common occurance inside a mixing tube, check for that after you've verified the orifice is the correct one for the type of gas that's being used.

Wow, this is a new one on me! Are you using true OEM parts for your source? If not, you may be getting sub standard parts. There are some companies that use generic parts and this isn't a good thing to do sometimes. Weatherking is a Rheem/Ruud product.

  1. The sensor that tells the furnace whether the gas is lit has got build-up on it and is giving the furnace bad information.
  2. The flame sensor is often a single wire or rod that sticks up in the center of the flame.
  3. You can shut off the furnace and the gas and clean the sensor with some sandpaper.
If that still doesn't work, the sensor may need to be replaced.

not only do you need the nozzles....you will need the spring changed in the gas valve and a manometer to set the proper gas pressure output from the valve.If you change the jets only you could do alot of damage to your furnace.
