Step 10. Installing a FTF10 CTDTM Round Termination:
1.Hold the FTF10 CTDTM over the top of the last chimney section installed (Figure 34 ).
2.Center the inner slip section into inner flue pipe and slip down.

3.Center the outer locking section over outer flue pipe. Push down until all locking tabs are firmly engaged and locked.
4.Pull up slightly on CTDTM to ensure the locking joint is firmly engaged and locked.

Note: It is recommended that all exterior ex- posed metal fireplace components; such as terminations, flashings, storm collars and/or flue be painted with a premium quality, high temperature, rust preventative paint designed for metal. This is especially important when installations are made in abnormally adverse or corrosive environments; such as near lakes, oceans or in areas with consistently high hu- midity conditions. Consult the paint manufac- turers instructions for proper preparation and application.
TEN FOOT RULE SUMMARY
The minimum chimney height above the roof and/or to adjacent walls and buildings is speci- fied by all major building codes.
If the horizontal distance from the peak of the roof is less then 10', the top of the chimney must be at least 2' above the peak of the roof.
If the horizontal distance from the chimney edge to the peak of the roof is more than 10' a chimney height reference point is established on the roof surface 10' horizontally from the chimney edge. The top of the chimney must be at least 2' above this reference point. In all cases, the chimney cannot be less then 3' above the roof at the edge of the chimney.
The 2' in 10' rule is necessary in the interest of safety but does not ensure
MULTIPLE TERMINATIONS
If more than one termination is located in the same chase or within the same general proxim- ity, we suggest they should be separated in distance at least 24" horizontally from flue cen- ter to flue center and stacked or staggered vertically at least 18" apart, from the termina- tion of one smoke exit to the termination of another smoke exit (Figure 36 ).
This suggestion is provided in the interest of better operation. If the terminations are located too close to each other, smoke may migrate from one flue into the other.

FTF10 CHIMNEY COMPONENT CALCULATIONS
The minimum installed height of the com- pleted fireplace system is 15' 0". The maxi- mum height is 60' 0".
To determine the number of chimney sections and chimney components required, follow these steps:

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
1.Determine total vertical height of the fire- place installation. This dimension is the dis- tance from the surface the fireplace sets on to the point where smoke exits from the termination.
2.Determine the number of chimney compo- nents required, except chimney sections. This would include firestop spacers, stabilizers, roof flashing, etc.
