WARNING

Fire Hazard

Some objects will catch fire or explode when placed close to heater.

Keep all flammable objects, liquids and vapours the required distance away from the heater.

Failure to follow these instructions can result in death, injury or property damage.

The flue must terminate outside of the building. Flues and air intakes must be a fully sealed system and correctly sized for the model. Flues should be assembled as detailed on Page 10, Figure 3 through Page 11, Figure 6. The joints between the flue terminal and the roof or wall must be properly sealed. If the flue passes through a wall or ceiling of combustible material, it must be enclosed by a sleeve of non-combustible material and be separated from the sleeve by at least a 25 mm air gap.

Flues and air intakes must be adequately supported so that the heater does not bear the weight of the pipes.

For flue termination See Page 10, Figure 3 through Page 11, Figure 6.

6.2Type C12, C32 & C62 Appliance Room Sealed.

The heaters are designed to be installed as room sealed appliances. The flue and air intake are run as separate pipes to the special concentric wall or roof

terminal. See Page 11, Figure 6.

6.3 Type B22 Appliance

The flue must terminate outside the building and be fitted with a low resistance terminal.

See Page 10, Figure 3 through Page 11, Figure 5.

6.3.1 Air Intake Terminal Cover

For Type B22 appliance installations, an air intake terminal cover is an available option. The cover is scored flat sheet metal that must be bent into shape. See Page 10, Figure 4. Remove and retain the screws for the air inlet spigot. Use these screws to attach the cover in position over the spigot.
