8. Install the ventilation pipe-work, including fan and vent cowl to composting container (sample installation shown).
The GT airflow requirement is provided by 100mm pipe and incorporates a continuous running fan (supplied). Consider how the fan will be
powered (240VAC or 12VDC) and ensure the fan housing is accessible for maintenance. Ensure correct airflow of the fan away from the
composting container.
The ventilation pipe should rise perpendicularly with as few curves and elbows as possible, the vent cowl placed on top. Don’t use pipe cement
for fittings near the fan & composting container – the push fittings should be tight enough for this purpose, and this allows you to dismantle
and service the vent system as required.
The following is an example as to a standard vent installation – there are many permutations possible and if in doubt, contact us for discussion
and guidance:
1. Attach the rubber joiner to the vent outlet of your GT container in situ. Cut off a short piece of vent pipe and insert half into the rubber
joiner, half out. Attach the 45 degree bend, pointing backwards. Cut a hole in the wall (if present), allowing the vent pipe assembly to traverse
the wall.
2. Install the fan by cutting off 2 short pieces of the vent pipe and inserting the fan as a joiner. Plug the fan into the power supply and
ensure the airflow is away from the composting container, upwards towards the exhaust end.
3. Attach the Y joiner as per the picture. Cut off a short piece of vent pipe and insert into the Y – joiner at the bottom. Finish with
attaching the cap. This is your moisture trap, which should be emptied every few weeks by undoing the cap, letting the water drain out and re-
attaching the cap.
4. Attach the remaining vent pipes with joiner and attach to the house wall using the pipe fasteners. Add additional vent pipes, joiners
and pipe fasteners as required. Cap with the vent cowl. Fasten the screws on the rubber joiner. Congratulations, you are done!
Remember that warm air from the composting chamber (the composting process generates its own warmth) naturally rises, and that sharp
bends restrict airflow – designing the vent piping correctly will improve natural operation.
Warm air holding moisture entering a cold vent can result in condensation. Install the supplied condensate trap as per the drawing. Consider
insulating the outlet vent piping.
