Gas Furnace Questions Please Help

[Guest]

Hello all need some help here...

1st, I randomly smell something in the air that reminds me of gas... I smell it in the basement sometimes and in the kitchen at times. Is this normal? Can it harm plants?
-I have a gas furnace, and gas stove/oven (range)

2nd, What's this talk I hear about negative air pressure and the furnace having problems like small explosions? Could anyone explain negative air pressure and what causes it?

3rd, I want to completely shut off my furnace for good, electrical and gas. I read online I just shutoff the circuit for the furnace, and then turn the gas valve to off. Is it safe to do this over a long period of time like 12 months?

The reason I want to shut off the furnace is, I plan on using the heating vents in the basement for exhaust and intake for my basement grow... so I'll be taking apart the furnace's duct system to get to the vents in the floor boards.

Another reason I want the furnace off is I'll have a lot of high powered fans pulling air in and out of the basement, which is what I think causes negative air pressure, which could cause problems with the furnace. Am I right?
-Could this negative air pressure cause any problems with my gas oven/stove?


I really don't like gas... especially all this talk how it lets off toxic gases like CO... is there anyway I can completely shutoff the gas coming into the house? And then I can just figure out another way to cook my food? Any ideas?

Thanks folks

Negative air pressure

Exhaust fans may be running in your buildings to remove smoke, fumes, and contaminated air. If you don’t have a make-up air system - or a large enough make-up air system - you have a negative air pressure condition.

Other building conditions such as temperature gradients can cause this phenomenon.

Negative air pressure means that air is drawn into the building to replace the air removed by exhaust systems or other building conditions.

Negative air pressure creates many problems:

* Drafts at the floor level
* Back drafting down furnace stacks
* Cold spots and wind chills in working areas
* Exhaust fans starting to operate inefficiently
* Strong air inrush when a door is opened..

This inrush of air brings with it fumes, insects and the outside climate. Make up air fans are used to offset negative air pressure.

So does this mean you need the same amount of air coming IN, that you have exhausting? Or just more intake than exhaust?

...SO the problem with the furnace would be because there's more exhaust than intake in the house, there are gases being drawn from the furnace which result in excess gases like CO? Do i have it right or no?
-Can this happen with a gas stove/oven as well?

Here is the problem in a nutshell;

There are too many appliances pushing air out of the house such as bathroom fans, central vacuums, range hoods, clothes dryers etc., this can be significant with no easy way for replacement air to get in. The result creates negative air pressure in the house which means the house becomes more interested in trying to suck air in than pushing air out.

This can interfere with the air supply for your furnace and other fuel-burning equipment. As air tries to enter the house through the only means available, which is the existing flues of your furnace, wood stove, fireplace and gas hot water heater, the reversal causes these appliances to spill flue gases into the house rather than exhausting them.

This makes your wood stove smoke back, your furnace and hot water heater dump carbon monoxide into the house!! What is needed is an easy efficient source of make-up air to equalize the pressure and has the ability to feed fresh air for your furnace and other fuel-burning appliances that have become starved for air. This is what "Pure Air Plus" can provide using a "Plusaire" residential ventilation systems filling your house with clean fresh air every day!

yea im right im so smart look at my replying to my own thread wooo im cool

Ok so to cure this negative air pressure you need air coming into the house, right?

Does it matter how this air is coming in?
What if I setup a dryer vent and had a big ass 900 CFM fan running as intake 24/7? Would that do it?

I'm really not sure bro,perhaps you should consult yourself again lol

Good Lord; crack a window and call it good, man.

Well I need to exchange the air in the basement somehow...

What I am thinking is...

I exhaust through 1 bedroom's heating vent in the floor boards. And intake from another bedroom's. Both bedrooms have window AC units so those will bring in fresh air to the rooms.

Will this do it?
