I have a englander nc30. I recently checked for air leaking from gasket with the bill test, it failed. I replaced the gasket with a gasket from the englander store and installed as directed. I am still able to pull the bill from the top and bottom easier than I should, the door has no adjustments and as stated the gasket is from the englander store 3/8 in high density. The hinge and latch side pass the bill test. Any help on solving this and troubleshooting is appreciated. Is it possible to have air flow out from the gasket, I understand the air will be drawn in due to draft.
