I recently purchased an Englander summer's heat stove back in December. Model # 25-pvdc/55-shp10. It has been working great up until yesterday when I started to get an intermittent noise coming from the exhaust blower area. Just wondering if anyone has experienced this or not. It's hard to describe it, but it just started a day or so ago. It seems to be still exhausting the air just fine and everything as of this point still seems to operating correctly. I will call englander tomorrow, just wondering if there was a quick fix for this right away. Hope that maybe it will just be a cleaning and hopefully the motor is not going bad. The other issue I was hoping to have someone answer is the rate of pellets that are used. I've read from other posts that you can reduce the amount of pellets used on the 1 heat range setting. When it gets into the upper 30's and lower 40's (farinheit), running the stove at 1 is even too warm. And I'm using pellets that aren't needed. Can anyone tell me the procedure to reduce this rate? What are the settings that I need to set? Thanks, Mike.
