II. Best Outdoor Boiler Burn Practices
Read and follow all operating instructions.
A.
Fuel Used:
You may burn any seasoned hardwood. A well seasoned piece of wood will feel
significantly lighter than one of the same type and size with high moisture content. Higher moisture
contents will result in reduced burn times as heat will be used up drying out the moisture for the wood
to burn. Never burn driftwood, painted, stained or pressure treated wood. Do not burn trash, plastics,
gasoline, rubber, naphtha, household garbage, material treated with petroleum products (particle board,
railroad ties and pressure treated wood), leaves, paper products or cardboard.
B.
Loading Wood:
Keep wood covered and store outside of clearance area listed on page 4. For a more
efficient burn, always add wood before the previous load has burned out. Most often the boiler can be
loaded in the morning and at night. Burn times vary from 6-24 hours depending on fuel being used,
installation, temperatures maintained and size of area being heated. Nature’s Comfort makes no
guarantees on burn times as there are too many variables outside of its control.
C.
Starting the boiler:
Fill the boiler with water (see page 14). Do not use combustible fluids or chemicals
to start a fire. Use small pieces of split kindling together with crumbled newspaper and add larger
pieces. For when starting a cold GT-220, open smoke bypass and leave open until water temp is at
least 170F so the firebrick can get hot enough to start gasification. To maintain the best operating
conditions, set the aquastat between 170-190F with a 3 degree differential (see page 10).
D.
Location & Chimney:
A 6” T with cleanout and at least 3’ of extension must be purchased separately
for installation and can be obtained from your local supplier or Nature’s Comfort. Install supports as
directed by pipe manufacturer. It is recommended that the boiler be located with due consideration to
the prevailing wind direction.
1
We recommend a distance of at least 100 feet be kept if prevailing winds blow towards any other
residence not served by the boiler, it is recommended that the stack be at least 2 feet higher than
the peak roof line of that residence.
2
If located more than 100 feet but no more than 150 feet to any residence, it is recommended that
the stack be at least 50% of the peak roof line of that residence, plus an additional 2 feet.
3
If located more than 150 feet but no more than 200 feet to any residence, it is recommended that
the stack be at least 25% of the height of the peak roof line of that residence, plus an additional 2
feet.
