Our home came with a Garrison One wood stove. We have used it only occasionally over the past 11 years. We received no documentation or instructions with the purchase of the home and I only recently learned that wood stoves should have fire brick installed. Upon inspection, I see that the stove has two fire bricks currently installed on the sides, with a spot for two additional bricks to be inserted. However, I do not see any place to install fire bricks along the back or the bottom. Is it needed in this wood stove? It takes an awful lot of wood and time for the stove to put out any heat, so my guess is this could be the problem. Any help would be greatly appreciated! Thanks.
