VENT INSTALLATION –
INDOOR INSTALLATION OR OUTDOOR SHELTER
Flueing must be in accordance with AS/NZS 5601.1
Always vent the heater to the outdoors, see Note*.

in the venting installation instructions.

pipe is allowed in some circumstances. Consult your local code official for detailed
information.
