Just wondered if any one could help me becasue i cannot seem to find information regarding warm air units and their ventilation requirements.
I am currently trying to write up a portfolio for a gas course i am studying but i am not sure whether warm air units require air for ventilation when installed within a compartment (i.e. cooling vents to allow heat generated by the appliance to dissipate).
Also am i correct in thinking that warm air units obtain their combustion air via the flue, or are there some types that gain their combustuion air from the room they are situated in.
Any info would be appreciated.
