Hi all, I would like to know if someone has a secret to adjust the latch on Hearthstone's door? We have a Castleton and a Heritage and both are almost new : about one month of occasional fires. When these stoves were new, the latches were working like butter smooth, just like if they were not closing tight as the movement is smooth, no noise, no *crich croch...* feelings on the door's handle. But very rapidly, the latches became rude and make a metalic rubbing noise. I tried to adjust the latches like indicated on the Hearthstone informations but never been able to get them like when new??? So I hope to find the secret here. Thanks
