No
the chimney needs to be big enough to carry away combustion products, if the brick chimney has a 10inch square to carry the smoke (100sqin) 28.3sqin for a 6inch round chimney wont do it
needs to withstand combustion heat, mild steel gal wont.
building codes specify what you can use in your region and diameter / house size rules
Selkirk style chimneys sell and are so priced for the reason

I can hear the wind blowing extremely noisy from my gas fire /chimney


It is not likely blowing from the fireplace, rather your hearing outside wind noise through the chimney pipe.
On windy days this is normal.
The noise can only be limited by the flue pipe damper and the length of the pipe.

Hot water temp seems ok but flow has got slower. Does not appear to be a problem with the diverter valve, as it is not bypassing. (this valve was changed last year) Mains cold pressure is fine. Boiler...


The last sentence in the description of the problem, says it all.

I too, have had the problem, Tony. But, in addition, to the hard water,I discovered something that I didn't know. In our home's water system (our home is 30 years old) , someone prior to our ownership had installed a 6' section of galvanized pipe (possibly a repair). If you're not familiar with galvanized pipe and what hard water (High iron content) will do, it rust from the inside out. This 6" piece was almost totally clogged with rust and corrosion. This is also the effect it can have on a water heater. Especially, the sacrificial anode rod inside the heater (if it's an electric water heater) That's why it's so important to drain and flush your water heater, at least once a year.

I mention all of the above, because you very well, may be experiencing the same issue. The way to resolve it requires a little detective work on your part. Check you piping to see if any is galvanized pipe, rather than copper or PVC. Keep in mind, that the sink fixtures, may very well may be galvanized, if your home is 30 or more years old. If you find any, I highly recommend replacing it, before something goes wrong in the middle of the night or while you and your family are away from home. If you hard water is a result of using a well, place a whole house water filter on the main incoming water line. It does not have to be a charcoal filter. And to make your water more palatable, install an automatic water softener. For me, it was all money well spent.

Hope this helped you to troubleshoot and solve the problem. Please let me know. Thanks.

I was just wondering if the EPA pellet stove needs a full chimney on the outside wall or if it is just vented l with a short chimney. It says is has an outdoor air kit. I'm not sure what that intails ...


The approved method of exhaust venting is a full Type L or PL Pipe chimney. The height of which must be a minimum of 3 feet higher the highest roof structure. The outdoor air kit is used to pull fresh combustion air into the system from the outside. The exhaust venting can go horizontally for no more than 2 ft and then must elbow up to what I stated above. OR if you have a single story home, it can go up through the ceiling, through the attic and terminate above the roof. Any time the vent pipe passes thru a combustible surface it must have a fire stop.

Keep in mind, this was just a brief overview of what is required. Each stove manufacturer as it's on guidelines for safe installation that will not only meet EPA Standards, but also your local Building Code Standards and NFPA Standards. Not installing it properly or not having it professionally installed, may void any claim you may have in the future with your homeowners insurance, that resulted as a loss, because of the stove and/or it's installation.

Hope this helps.

well first, clean out the vent exhaust. after all those years, who knows whats inside...you must have burned off dirt and dust. unless the unit has fans in it and they are defective....

I suggest to contact a service company

I have an old Efel Kamina wood stove that I want to install in a new structure that does not have a chimney. I need the manufacturer's specifications to determine the distances from combustible materials...


From an insulated wall - 30 inches. Not insulated - 38. We have one as well and are trying to find out information about it.

Southport Stove Inc. Serial # F90309 ICBO 3 500 Another number: 079-66 It's a Kamina.

Any information would be great!

I had my a/c charged today because it has not been cooling the house down. It took less than a pound, but it still blows worm air. Fan and compressor all running. I cleaned outside unit, filters, replaced...


It could be that it is not charged correctly. Check the insulated copper
line outside if it is sweating and the condensor is discharging hot air, then the ac is doing all that it can. Check the evaporator inside to see
if the drain has condensate coming out of it.

Getting the heat out of the attic is a good idea, but you must have enough make-up air in the attic for the fan. If you do not have enough
make up air, it will start to draw air from inside the house. One way to check this is if you have a gas water heater and or furnace. If you put
a flame by the exhaust pipe in the basement and it blows it out, then you now have a backdraft problem.

Run the AC withoutthe fan, my real guess is the unit is not properly
charged or you do not have a big enough AC unit.

Air intake via hose & window or intake from room only?


Hello artrey3 The answer is yes, BUT the unit will be exausting room/basement air outside ruining any efficency the unit is rated for.Also you will need makeup/fresh air in the basement. The unit exausting air can put the basement in a vacuum/negitive pressure pulling in air from the chimney!

Exhaust hose is too short need extention for it to


Hello. I can help you. For safety use a piece of galvanized duct pipe, of the correct diameter and clamps. These are common items available at most any hardware store.

Adding on with more plastic hose is a fire hazard.

Re: Weather King heater


If it is an older weather king unit (10yrs+) strongly think about replacing it. Known for there problems any expensive to fix. To check the chimney, shut unit off and remove flue pipe from chimey connection. It is always better to have a professional chimney swqeep do it. I really don't think the thermocouple has anything to do with it, it probable does'nt even have one. If the thermocouple is bad, the unit will not work at all.

Good Luck,
