Please follow the below requirements during the installation of flue duct:
(1) Please use the flue supplied by our company, referring to Fig. 11 about the installation
method. If the flue duct is too short, you can extend it aptly. Check the flue duct and see if there
is any damage or leakage every half a year. Install the flue after the heater body is fixed. First, put
the fixed flue through the hole in the wall, then insert the elbow into the exhaust outlet of the
heater smoothly, the flue end should have a 2° downward inclination (Fig. 11), otherwise the
rain may flow into the heater and damage it.
(2) The length of the flue duct should be less than 4m, and the number of elbows should not be
more than 4 ( one elbow equivalent 1m straight pipe).
(3) The distance between the flue duct and the combustible materials should be more than
150mm. If the flue duct needs to get through the combustible materials or wall, it should use the
heat shield material to pack the flue duct with the thickness over 20mm. （Refer to Fig.7）
(4) No cement between the flue duct and wall for the convenience of maintenance.
(5) The flue duct should be fixed tightly. The connection part could use self-adhesive foil to avoid
the waste gas going back into the room.
