Cautions for flue installation
• Please use the flue supplied by our company.
Other flues with different specifications are
strictly prohibited. Do not change the speci-
fication of the flue.
• The installation of the flue must be correct,
otherwise the waste gases will flow back and
be dangerous (Figure 5.14).
