Required with this boiler: a flue kit
Ideal supplies this boiler without a flue. The Flue kit selector above Add to cart adds the Ideal 60/100 horizontal flue kit 0.6m (208171, walls 181-556mm) by default, as a separate line in your basket. Pick the 0.8m kit (217442, 601-816mm) for thicker walls, or the 60/100 vertical roof flue kit (211039) for a roof exit.
Only choose "I already have this" if you already have a compatible Ideal 60/100 flue kit for this boiler. Check maximum flue lengths and terminal positions in the installation manual.
What's included
- 1 x Ideal Logic+ Heat2 boiler in the output you select, with wall mounting plate and hardware pack, as supplied by Ideal
- No flue included: choose your flue kit with the selector above Add to cart
