Flue for Economaire Air Heaters

The flue path can be horizontal or vertical. For maximum equivalent flue lengths and flue size see tables. To calculate equivalent length refer to example below where:

 4" Flue (100mm/60mm) 5" Flue (125mm/80mm)
45 bend =1m equivalent length45 bend =1.5m equivalent length
90 bend =2m equivalent length90 bend =3m equivalent length
