A:AnswerI doubt that 29" will be enough. The dryer has the vent at the back and you will need to connect this to the vent to the outside. My connection is a via fairly large diameter tube which runs along the back of the dryer (between the dryer and the rear wall) from the dryer vent outlet to the vent to the outside. This results in the front of my dryer being 34" in front of the rear wall. You will need to evaluate how your set-up would be configured and perhaps discuss this with the store people.
A:AnswerYes you can. I actually have both the gas and electric model because I'm in the military and move to locations that might have either. The gas is about $100 more.
A:AnswerActually purchased my dryer 3 weeks ago and have not had any issues with my clothes not drying. Ensure that you clean the filter, check your dryer settings, because you can adjust it to the amount of clothes that you put in it.
