Revised August 2009.
The chimney flue connected to the Paxo® boiler should conform to the specifications below.
1 inch = 2.54 mm
1 m = 3.28 ft
12. Combustion Air
The boiler requires fresh air for combustion. The air supply affects the quality of the burn as well as the strength of the chimney draft.
If any fans are used in the room where the boiler is located, they should be installed not to create negative pressure, they should not be
pulling air from the room. On the other hand, you do not want too much positive air pressure, as it can cause the boiler to burn out of
control. You may need to pull outdoor combustion air into the room if there are back drafts, insufficient draft or improper
combustion. That can be easily checked by opening a window or door to see if the problem goes away.
13. Boiler Set-Up
The boiler is shipped completely assembled and ready for installation and use. The boiler should be inspected inside and out for any
defects or damage that may have occurred during shipping. After the boiler is placed in its permanent location and before the first
firing, the refractory tunnel will need to be positioned directly under the nozzle or nozzles, so that the flame shoots directly down into
the trough.
14. Piping
The direct connections to the boiler will be similar no matter which piping system you select. If you have specific questions please
seek the advice of a hydronic heating professional.
WARNING!
Paxo® wood gasification boilers should be installed in accordance with local codes. The boiler should be part of a
closed, pressurized system with a pressure relief valve, expansion tank and if possible, a hot water storage tank.
