Suggested Venting
Overview
The exhaust from indirect-fired heaters must be vented to a chimney or an exhaust
duct. Exhaust gases must rise in order to maintain a proper draft in the chimney or
exhaust duct.
Note:
The information presented below is intended as a general reference guide.
Local and national code requirements supersede these suggestions.
Before
installing the
machine
Adhere to all local and national codes.
Adhere to all fire prevention regulations.
Consult all appropriate governing bodies or local contractor for venting and
fresh air requirements.
Make sure that the room or building to be heated has sufficient ventilation to
ensure that the machine has enough air to function properly.
Duct
requirements
Do not use B-vent exhaust pipes to vent an oil burning machine. Contact
Wacker Neuson Product Support for recommended alternatives.
Check local codes for appropriate vent piping materials.
Machine
setup
Position the machine in a manner that avoids excessive vent bends (elbows),
and long horizontal runs.
Keep air inlets and outlets free from obstruction. Ensure that there are no bulky
objects or sheets/covers near or on the machine.
Routing the
vent piping
Route the venting pipes in a manner that avoids flammable materials.
Route the venting pipes in a manner that avoids contact with people.
Sufficient draft shall be created to assure safe and proper operation of the
machine (minimum 0.05 wc).
Avoid any 90° elbows or bends in at least the first 10 feet (3m) of exhaust ducts.
Terminating
the vent
piping
When the machine is connected to a flue pipe, the flue pipe shall terminate in a
vertical section at least two feet (0.6m) long.
If exhaust is to be vented out the side of a building, as shown in the lower left
diagram, the end of the exhaust pipe should be vertical and at least 2 feet
(0.6m) long. A rain cap should be installed to avoid any potential downdraft or
back pressure on the exhaust system.
DANGER
Asphyxiation hazard.
Exhaust gas from the burner contains carbon monoxide, a deadly poison. Exposure
to carbon monoxide can kill you in minutes.
f
Never run the machine indoors or in an enclosed area unless the machine is
vented properly according to local and national codes.
