byanapprovedheatingcontractor,asonlytheyhavetheessential

knowledgetocarryoutsuchwork.

- Nevermodifyuegascomponents.

- Never close or restrict the ventilation apertures in doors or walls

when operating the boiler in open ue mode; only start the boiler

when the ue has been fully installed.

- For operation in balanced ue mode, only take the appliance into

use if the balanced ue system has been fully installed and the

wind protector is not covered up.

- Thegascondensingboilermayonlybeinstalledinroomsthatare

protectedfromfrost.
