• Grounding Issues: A grounding issue can cause electrical interference that can affect the blower motor’s operation.

Formulas and Calculations:

While not directly related to the pulse mode issue, understanding some basic formulas can help you optimize your pellet stove’s efficiency and reduce heating costs:

• BTU Calculation: BTU (British Thermal Unit) is a measure of heat energy. You can calculate the BTU output of your pellet stove by multiplying the pellet consumption rate by the BTU value of the pellets. For example, if your stove consumes 2 lbs of pellets per hour and the pellets have a BTU value of 8,000 BTU per pound, the stove’s BTU output is 16,000 BTU per hour.
• Efficiency Calculation: Efficiency is the ratio of heat output to heat input. You can calculate the efficiency of your pellet stove by dividing the BTU output by the BTU input. For example, if your stove has a BTU output of 16,000 BTU per hour and a BTU input of 20,000 BTU per hour, the stove’s efficiency is 80%.
• Cost per BTU: You can calculate the cost per BTU by dividing the cost of the pellets by the BTU value of the pellets. For example, if a bag of pellets costs \$5 and contains 40 lbs of pellets with a BTU value of 8,000 BTU per pound, the cost per BTU is \$0.000015625 (5 / (40 * 8000)).
