III. Installing Boiler
Installation is to be performed by a qualified installer and shall comply with all the
requirements of the authority having jurisdiction over the installation.
A. Location of Boiler
The NCB boiler must be located to comply with the clearance requirements. Keep the firebox door
positioned so as not to point toward a structure so all fire danger is removed from the home. The
boiler may be installed as much as 250 feet away using an appropriately sized pump and piping
and still heat the house and hot water. However, if the boiler is located more than 100 feet away,
you may experience inefficiency and heat loss. A larger pump than the one supplied may be
needed for distances over 100 feet and/or any rise in elevation over 15 feet.
Locate the NCB boiler where it will be convenient for refueling and wood storage. Pex pipe and
power lines are to be installed underground between the house and the boiler and must be buried
below frost lines.
1. It is recommended that the boiler be installed with chimney extensions for due consideration to
any neighboring residences and to the prevailing wind direction.
2. Do not locate the boiler within 100 ft of a residence not served by the boiler. Be considerate of
neighboring residences, properties, parks, etc.
3. Do not locate the boiler near any combustible materials, gasoline or other flammable liquids or
gases.
4. The boiler should be located away from dry, grassy areas and any buildings
to minimize danger of fires.
5. Check with the insurance company and local codes or ordinances.
6. Do not install the boiler in an area where nearby structures or trees might cause down drafts.
7. Typically, outdoor wood burning boilers are located 40 to 100 ft down wind from the structure
served.
8. To aid in smoke dispersal, extra chimney lengths may be required depending on the distance to
surrounding structures.
Failure to keep the boiler area clear and free of combustible materials, gasoline and other
flammable liquids and vapors can result in severe personal injury, death or substantial
property damage.
A full concrete pad or footings just under the feet are not necessary for the installation for the boiler,
but is recommended to prevent frost heaving. Four concrete footing blocks 8” X 16” X 4” will suffice
if desired. You may add additional layers of blocks for ease of loading wood. The figure below is for
outside foot dimensions.
