Wood Stove Back Pressure

Ontario, Canada   

We went the first 29 days on November with no difficulty starting a fire in our Jotul 500 F wood stove. 

On the 30th, the lower level of our house was filled with smoke because of negative pressure. 

Is there a device available (less than the $450.00 I was quoted) to correct this problem?

You do not say what floor the stove is on nor the type of chimney used so I can only summarize.
Up here in the Cold Land while the fierce weather approaches. The colder the temp outside, the heavier the air in the chimney, the hotter the fire must be to maintain updraft.
In cold climates, like ours, it is hard to keep a negative pressure zone at bay. with everything we run in our homes.
If the Jotul stove is running and hot and the chimney is clear you have to look at your houses ‘Load’.
What other appliances were running when it started to smoke.
Anything that exhausts air OUT OF THE HOME will cause the chimney to bring in fresh air.The tighter the house, the harder the problem, homes need to breathe too
Bathroom fans, Kitchen range fans, central vac, the clothes dryer.etc etc will exhaust the house of air. Like plugging your nose and covering you mouth.
Think of what was running on day 30 and see if you can alleviate the problem.
If you cannot then an outside air might be needed.
