Can I put flue elbows straight on top of the boiler?

Elbows for offsetting can be fitted directly into the flue turret, or high level adapter on all our wall hung boiler variants. There is no requirement for running any straight flue length between them.

Please check our manual for total flue length allowance, as most extra 90 degree bends will result in either a 1500mm (Greenstar CDi Classic Range) or 2000mm (All other ranges) reduction and a 45 degree bend will lose 750mm (Greenstar CDi Classic Range) or 1000mm (All other ranges).
