Just wondering if someone can detail how they did a shut off on their OAK. Our basement bungalow installation/house came with a pre-installed OAK. It looks like a dryer vent hose with insulation inside and comes from ground level down to the stove through the wall. I was wary of this material it until I inspected it and saw it was rated as fire resistant.
The installer just stuffed the end of this vent into the stove's OAK entry. Because our house is so darn tight that when we run our exhaust items (dryer and/or vacuum) it will go into negative pressure and suck from any source it can - such as the OAK (and not the HRV). During shoulder season I sometimes I have to pull it out and stuff it with insulation when I am not burning as it draws in damp moist air. I also experience the ice cube factor when it is not lit in the depths of winter. I and would like to find a way to stop this, such as a "damper" or full shut off when we are not burning. Any suggestions on how to do this? Thanks in advance!
