VENTILATION
When installing the heater indoors, it is imperative that an adequate supply of fresh air is provided for combustion.
Failure to provide adequate ventilation voids all warranties and may be a danger to persons or property.
Two permanent openings shall be provided directly to outside. The openings shall be located to ensure the
distance between the top of the upper opening and the ceiling of the room or enclosure, and the distance between
the bottom of the lower opening and the floor of the room or enclosure does not exceed 5% of the height of the
room or enclosure.
The minimum vertical dimension of any free ventilation opening shall be 6 mm.
The minimum free ventilation area provided directly outside by each opening shall be:

The following diagram is provided as a guide only. All flueing and installation work must be carried out by an
authorized person. Flueing must conform to local regulations and to A.G.A. installation code AS5601. Care must
be taken to provide the correct ventilation and correct flueing materials in close proximity to combustible surfaces.
Do not install spa blowers in the same room as a gas heater. This is potentially dangerous to spa users.
Do not store chemicals or fuel in the same room as the gas heater. This may cause fire or explosion.
When installing in a garage the Viron Series Heater must be installed 450 mm above floor level.
