Equipment Details
Cleaning
(with switched off appliance!) We recommend
removing dust which has collected on the
heat exchanger and base plate of the heater
and on the impeller wheel of the Trumavent
fan, once a year before the heating season
starts. Clean the impeller wheel carefully
using a brush or tooth brush.
Blown air ducts
The air ducting outlets are generally of the
butterfly type and may be opened or closed
to control the quantity of air by adjusting the
butterfly valves. Twisting the disc in its
housing directs the flow in the direction
required.
For uniform distribution, outlets nearest the
heater should be closed more than those
further away.
One outlet on each leg of the air ducting
layout must be kept open at all times.
Under no circumstances should the air
ducting outlets be blocked.
