BOILER INSTALLATION
IMPORTANT NOTES
•
The Seton boiler does require a strong draft, which is provided by a proper chimney. The draft
must be measured by either temperature or a manometer. The manometer must read at least .06 on a 8
inch chimney while the draft is open and the boiler up to temperature. In the case no manometer is
available you can measure the exhaust temperature, it should read between 350° to 450° while the
draft is open and the boiler is up to temperature. This measurement must be done in the exhaust
stream not on the surface of the pipe.
•
The Seton boilers are designed to work with at least 15 Ft. of eight inch insulated stainless steel
class A chimney, without a chimney cap . But you can use a “China Cap”
•
If the chimney is too tall or the draft is too strong you will need to install a draft restrictor not a
barometric damper.
•
Do not run the boiler with out connecting both relief valves to drain pipes, drains must run down
their full length and must not be exposed to freezing in such a way that they will fill with ice and
block the flow.
•
The second aquastat must be wired into the dump zone, so that any boiler temperature above 200°
will lower the boiler water temperature.
•
The boiler must be plumbed so that fill water is always available to it and that if the T&P relieves
water because of a high water temperature the cold fill water will flow up through the boiler to cool
it.
•
The Seton Boiler is not designed to be installed inside the living area, it must be in an enclosed
structure.
•
The Seton boiler must in installed in a heated space, if installed in a small shed it should be well
insulated. The small shed should not be more than 2,000 Cu. Ft. unless it is heated.
•
The draft must close tightly and must open at least 60°, do not limit the draft air with the draft
motor.
•
Provide combustion air for any room the boiler is installed in.
•
The Seton Boiler does not smoke or smolder in the off cycle.
•
The white exhaust during the off cycle in the first few cycles after filling the boiler is steam
caused by the high temperatures off the refractory chamber drying the charge.
•
A blue tint to the smoke during the off cycle is a sign of a combustion air leak in the draft or door
area.
THESE ARE VERY IMPORTANT NOTES,
DO NOT IGNORE, YOU CAN VOID YOUR WARRANTEE
IF AFTER THREE DAYS OF FIRING THE CHIMNEY OR THE BOILER IS DRIPPING
CONDENSATE, THE CHIMNEY IS INADEQUATE.
The Seton Boiler is the worlds most efficient wood boiler, it has very low exhaust
temperatures. If the exhaust temperature drops below 300° before it exits the top
of the chimney it will restrict the draft necessary for a clean burn, this will cause
the pressure vessel to form creosote and will cause the boiler and the chimney to
make water that will corrode the boiler and the chimney.
