I recently installed a gas range and I will soon be installing a 300cfm range hood. Since I primarily burn wood in the winter for heat and I don't want any back-drafting issues, I am planning on installing a make up air vent in my cold air return ducting (I have a gas furnace I use as a back up for heat). However, I have a few concerns with the make up air. It gets cold where I live (think sub-zero) during the winter. Will the make up air bring noticeably cold air in through the vents? My concern is that it will make some of the rooms cold in the winter by counteracting the wood stove's heat.
Will a make up air vent cause an issue in the winter

The make up air would only be pulling fresh air in when your furnace is running unless you add a small powered duct. If you use the furnace to circulate the house air without the heat on yes it will be cooler but make up air is a good idea especially in winter when the house is closed up tight.
