This problem is symptomatic of a stove in need of a deep cleaning. The convection tubes through which the room air travels and warms likely have become insulated with fly-ash or creosote. Also, the fan that pushes the air through the convection system may have lost efficiency due to dust, carpet fibers, or pet hair build-up. These factors added to the probability that you are not getting the maximum amount of heat available from your fuel due to a poor air to fuel ratio point to the need for a deep cleaning.
Besides the daily, weekly, and monthly maintenance outlined in your manual, have your pelletstove cleaned professionally once a burn season or after running 2 to 3 tons through it. I think the best time to have this done is late spring or early summer after you are done using it for the season. This way you pelletstove is all ready for you in the fall when the first cold spell surprises you and you want to fire up the stove. Having your pelletstove cleaned annually and professionally ensures the stove’s longevity and burn efficiency.
After the stove is cleaned for the season, if your service tech has failed to leave the stove unplugged, unplug it yourself -even if you have a surge protector.
Yes, you can indeed have a flue fire in a pelletstove. Several factors can create this scary event. Improper air to fuel ratio (a continued lazy flame), constantly running the stove on low, poor quality pellets and failure to properly maintain your stove are all things that can result in a flue fire. These are things though that you can easily correct. Other factors may include a restrictive venting configuration or a venting system that in uninsulated. We recommend insulated pipe be used on all installations, including fireplace insert installations. Insulated pipe keeps the flue gasses from cooling, condensing and glazing.
Many stoves have a 10-15 minute start-up cycle. At the end of the cycle the stove seeks confirmation that there is a viable fire in the burnpot. Typically a heat sensitive switch called a bimetallic snap disk is used. Heated up it closes, allowing electricity to pass across it. If the switch fails to close during start-up, the stove, lacking proof of fire, shuts down. This is an inexpensive part and should not cost more than $20.00 dollars.
The flame should be bright and active, more white than orange, low and compact not tall and wispy. The pellets may roll around a bit lazy but should not “popcorn” out of the burnpot. If your flame is lazy make sure the holes in the burnpot are open and all access doors are sealed. If you have an air inlet control (damper) try pulling it out a bit. Have your pelletstove and flue annually professionally cleaned to ensure maximum efficiency.
