Page 8: Best Outdoor Boiler Burn Practices
II. Best Outdoor Boiler Burn Practices Read and follow all operating instructions. A. Fuel Used: You may burn any hardwood, softwood, pallets that have been split up and coal but NEVER burn driftwood, painted, stained or pressure treated wood. Do not burn trash, plastics, gasoline, rubber, naphtha, house hold garbage, material treated with petroleum products (particle board, railroad ties and pressure treated wood), leaves, paper products and cardboard. -
Page 9: Heating The Home
The following are general guidelines for wood selection: Keep wood covered but open to the wind as rain and snow will greatly hamper the seasoning. Hardwoods burn longer than softwoods as they are denser and have more available BTU’s. Larger pieces burn longer than small pieces but take longer to season properly. 20% moisture content is optimum. -
Page 10: Pex Pipe Connections
J. Pex Pipe Connections Single-Zone setup Boiler shown is set up as a single-zone. All boilers save for the NCB-120 come with ports for 2 hookups (2 Pump not included.) Red Pex pipe goes from the pump to heat exchanger(s) in home. -
Page 11: Insulated Pex Pipe
Insulated Pex Pipe We highly recommend the use of insulated pex pipe for the best heat transfer possible from the boiler to your home. 4” triple wrap or 5” five wrap insulated pipe is available for purchase through your dealer or Nature’s Comfort. Adjusting Airflow On Draft Blower The turn buckle must be adjusted so the damper covering the intake to the blower is open only ¼”... -
Page 12: Plumbing Hookup
C. Plumbing Hook Up 1. Plumbing and electrical connections are made through the rear access door. 2. The water lines must be buried below the frost line to prevent freezing. The depth of the trench varies in different regions of the country. Be completely sure about the correct depth needed before the insulated pex pipe is installed underground. -

low iron content if possible. During the first heating cycle the water might expand and overflow. This is normal and will occur anytime too much water has been added. After priming and starting the circulation pump and bleeding the heat exchanger let your boiler heat up and run for 24 hours then top off the water again. - Page 14 Make sure the fittings for the supply and return lines are easy to get to once the heat exchanger is installed. You should be able to find a heat exchanger to fit most popular sizes of plenums. If you are unable to your ductwork must be modified to accept the heat exchanger.

Install the braces the proper width apart as shown above. Secure them in place using pop rivets or self taping screws. You will need four pieces, two on the top and bottom. Slide the heat exchanger carefully into the plenum to check the fit again. Once proper fitting is verified, you can seal off the ends of the heat exchanger and the hole you made in the plenum with foil tape made for ductwork. -

L. Air Flow through Plenum The motors on most force air furnaces have three speeds to provide various rates of air movement. Please consult a local furnace specialist if you want to change the airflow of your existing furnace system. M. -

Page 19: Warm Weather Operation And Hot Water Bypass
B. Warm Weather Operation and Hot Water Bypass Operation in warmer weather will be tricky as too many coals will cause the water jacket to boil if not enough heat is being used. To compensate, load less wood and/or purchase a chimney damper to reduce draft through the chimney. Adequate water circulation is critical for preventing water from boiling (see page 11). -
Page 20: Hooking Up The Outdoor Boiler To An Existing Boiler
D. Connecting the Boiler to an Existing Indoor Boiler A plate heat exchanger is needed to transfer heat from the outdoor boiler to another indoor boiler or hydronic system so that the two systems remain isolated from each other. As shown in the above figure, the two systems are totally isolated from each other so that the existing hydronic system remains undisturbed and functions exactly as before. -
