My question is: on the NewEnglander 25-PUF what do the HEAT RANGE and BLOWER SPEED buttons actually do when set. It would be nice to understand the entire combustion mechanics. The stove works great. I would like to be able to get maximum heat most of the time. When I am gone for the weekend I need to cut back to reduce ash build up because I am not there to clean it for 2-3 days. I did this last weekend leaving it on 5 heat and 5 blower for 48 hours. would leaving it on 3 heat and 5 blower give me another 24 hours. Three days would be the maximum amount of time I would be away. Please get back to me on my question about the function of the HEAT and BLOWER buttons. Thanks Dick
