Ensure the inner fl ue section is sealed at all joints, otherwise incomplete combustion may result. For ease of
assembly, it is recommended that a small quantity of petroleum jelly is used to lubricate each fl ue seal, before
fi tting fl ue sections together.
Any terminal must be fi tted with a guard if less than 2m above ground level or if it is in a position where it may
cause harm to persons as a result of touching a hot surface.
Care must be taken to avoid long horizontal runs of fl ue duct and continuous discharge of condensate from a
horizontal fl ue terminal - Ensure that the fl ue slopes back by 3
