After 2-3 years of my wife pestering me to invest in a pellet burner in our newly-built house, I finally buckled and went for a Fahrenheit furnace, which we had installed professionally a couple of days ago (Tuesday, December 28th) by a local dealer in Western NY (near Buffalo). I'm doing the heat ducting myself, so the installers took care of bringing the 380 lb. Fahrenheit unit into my basement, and installed the combustion intake vent as well as the Type L exhaust vent for the furnace. Photos of the installed Fahrenheit unit can be found below.
The only issue after installation was some exhaust leakage into my basement (subtle wood smoke odor inside my home). Upon ignition of the pellets inside the Fahrenheit unit, visible smoke could be seen coming from the Tee at the bottom of the vent (for clean-out), which I promptly sealed with high-temp RTV silicone. I could still smell exhaust after sealing, so I shut the furnace down and re-ignited some hours later, and more smoke could be visibly seen (after initial ignition) coming from the elbow near the top of the Type L exhaust vent, where the exhaust goes outside the house, so I gooped on more high-temp RTV silicone and lathered it by hand all over the elbow joint (the installers sealed the inner vent with red RTV silicone and used aluminum tape at the seams). I'm relatively confident I have sealed the exhaust pipe and that it is air-tight at this point, but was wondering if I need to wait the full 24 hours for the silicone to cure before I can fire up my Fahrenheit unit, the stuff dries to the touch quick but it does have a cure time. The L exhaust vent does not get very hot, I would estimate 120°F maximum, even when the furnace is cranked at the highest setting (Level 5).
Overall, I'm very impressed with the furnace itself, Fahrenheit did a great job of engineering their product and it pumps out a LOT of heat. Also, their support team is very responsive and helpful. It's nice having the unit in my basement as we don't have to worry about any ash or dust/dirt from pellets in our living space.
