Typical flue installation
3.4 Flue Fitting Instructions
1. Fit spigot adaptor E4 to heater flue spigot in the
direction shown. Note! Fire resistant silicon sealant
should be used on this joint.
2. Fit elbow E3 into spigot adaptor E4 for horizontal flue
routes or E2 for vertical flue routes
3. Fit flue pipe into E2 to give required length of flue
route. Refer to manual for maximum horizontal and
vertical flue routes.
4. Determine correct position and fit outer wall plate
using 4 screws and wall plugs provided. Cut flue
sleeve to suit wall thickness and fit flue pipe through
wall to outer wall plate. Fit inner wall plate and fix
using 4 screws and wall plugs provided.
5. The lengths of flue pipe may be cut to obtain
correct length of flue route required.
