Combustion Air Supply / Corrosive - Waterco Turbotemp 200HD Installation And Operation Manual

COMBUSTION AIR SUPPLY
For indoor installation, the heater location must provide sufficient air supply for proper
combustion and ventilation of the surrounding area (in accordance with AS/NZS 5601.1).
The minimum requirements for the air supply specify that the room in which a heater is installed
should be provided with two permanent air supply openings; one within 30 cm (12 in) of the
ceiling, the other within 30 cm (12in) of the floor for combustion air, in accordance with the AS/
NZS 5601.1 as applicable, and any local codes that may apply. These openings shall directly,
or through duct, connect to outdoor air.
Waterco Limited does not recommend indoor installations that do not provide combustion air
from outside the building.
