Caution:
Chimney stacking for the burner venting should be made by a
licensed technician and conforms to all federal, state and local codes regarding
burner ventilation.
In northern locations, ensure provisions are made to prevent cold down
(negative pressure) drafts from freezing the coil when the machine is not in use.
Install UL listed weather cap (on top of the building).
If the machine is used in an enclosed area and you are putting a chimney on it,
be sure a draft diverter (available as an option, see Figure 5) is installed and the
chimney is as at least the same size as the stack on the machine (10 inches).
Poor draft will cause the unit to soot and not operate efficiently. Position the
machine to ensure the straightest stack possible.
Figure 5:
Optional draft diverter. It is installed just above the burner.
Caution:
Never reduce the size of the stack. Do not retrofit to a smaller
stack. If the stack is restricted, there the machine will have enough air
movement.
