Waterco Turbotemp 200HD Installation And Operation Manual page 29

4. Install vent pipe so that it can expand and contract freely as the temperature changes.
Support the vent pipe according to applicable codes and vent manufacturer's instructions.
Pipe support must allow the vent pipe free movement out and back, from side to side,
or up and down as necessary, without putting a strain on the heater or vent body. It is
recommended to slope the horizontal pipe down to condensate trap at least 2cm/M (1/4
in per foot). Install "Approved" condensate drains at low points where condensate might
collect. Plumb condensate drains to a drain through hard piping or high-temperature tubing
such as silicone rubber or EPDM rubber – do not use vinyl or other low temperature tubing.
Follow drain manufacturer's installation instructions.
5. Use an "Approved" firestop for floor and ceiling penetrations. Use an "Approved" thimble
for wall penetrations. Use an "Approved" roof flashing, roof jack, or roof thimble for all roof
penetrations. Do not fill the space around the vent (that is, the clear air space in the thimble
or firestop) with insulation. The roof opening must be located so that the vent is vertical.
6. Vent Termination – Vertical (See Figures 14, 15 and 16), for height of vent termination above
the roof. Use an "Approved" vent terminal specified by local and national codes and your
manufacturer's instructions. A roof termination must be vertical.
7. Make sure entire installation is sealed according to approved standard.
