Actualy he can go out then up too.elkimmeg said:If it is a draft issue your manual describes the best ways to vent your stove. Though exceptable directly out the back, but not recomended
The best solution is to have 3 to 6' verticle rise before the exit spelled out in your manual.
His biggest problem being no outside air in his newer house and his air intake not opening. He can check his draft by watching his flame behavior but should have it checked by his dealer. Unfortunatly his dealertold him outside air was not needed. If he can tell us what the voltage at the outlet is we can help confirm that his combustion blower is not turning fast enough. Although at a minimum the dealer should come out and draft check it after he takes care of the venting and air intake...
Tundra have you checked the flapper on test with the window open yet and watched the flame?
