1. No pellets in hopper.
2. Feed motor will not run until ESP
senses 165 deg. F. Maybe you did not put
enough pellets in the burn pot before lighting the
fire.
3. Feed motor has failed.
4. Something is restricting flow in the hopper or
causing the slide plate to stick.
5. Firebox draft may be too low for low draft pres-
sure switch in feeder circuit to operate. Check for
closed doors, loose or missing gasket on doors
or hopper lid, faulty pressure switch.
PARTIALLY BURNED PELLETS
1. Feed rate too high.
2. Draft too low. (Check burn pot clean- out slide
and door gasket).
3. Burn pot or heat exchanger tubes may need to
be cleaned.
4. Combination of all the above.
SMOKE SMELL
Seal the vent pipe joints and connection to stove
with silicone.
FIRE HAS GONE OUT
1. No pellets in hopper.
2. Feed rate too low.
3. Something is restricting fuel flow.
4. Feed motor or draft motor has failed.
5. Power failure or blown fuse.
SMOKE IS VISIBLE COMING OUT OF VENT
1. Air-fuel ratio is too rich.
A. Feed rate too high.
B. Draft too low caused by a gasket leak.
LOW HEAT OUTPUT
1. Feed rate too low
2. Draft too low because of gasket leak.
3. Poor quality or damp pellets
4. Combination of 1. and 2.
Cleaning Burn Pot
Whenever your stove is not burning, take the op-
portunity to scrape the burn pot to remove carbon buildup.
A vacuum cleaner is handy to remove the residue. Be
sure the stove is cold if you use a vacuum.
Carbon buildup can be scraped loose with the fire
burning using the special tool provided with your stove.
Scrape the floor and sides of the burn pot. The carbon
will be pushed out by the incoming fuel. Always wear
gloves to do this.
Removing Ashes
Turn the Feed Rate Dial to number 1 approximately
30 minutes before removing ashes. This will result in a
cooler stove and ash pan.
Maximum Turbo settings are not needed in most
cases. Operating in the normal range is recommended
when maximum heat output is not required. The ESP
probe prevents the stove from being over-fired.
Keep the stove free of dust and dirt.
Helpful Hints
Fuel
Pellet fuels are put into 3 categories in terms of
ash content. Premium at 1% or less, Standard at 3% or
less and all others at 3% or more.
The 38+ is capable of burning all 3 categories of
pellets due to a patented feeder and burn pot system.
It should be noted, however, that higher ash con-
tent will require more frequent ash removal and may
provide less BTU's per lb. Normally, standard and high
ash pellets cost less than premium pellets and can be
cost effective when burned in the 38+.
The moisture content must not exceed 8%. Higher
moisture will rob BTU's and may not burn properly.
