Hints:
• Before making any holes in ceilings check for access behind the ceiling, taking
care to avoid ceiling joists, etc.
• Check the distance you want to run the duct. The shorter the duct runs the more
efficient the fan is.
• Remember! The hot layer of air is dispersed across the whole ceiling so it is not
necessary to install the inlet grille directly near the fire flue. The grille should be
at least 1 metre from the flue in order to avoid excessively high temperatures.
• Although the fan is ball bearing mounted and very quiet it is recommended to
mount it on a solid surface such as the top plate of a wall partition or, better still,
suspend the unit from the rafters. This will ensure the quietest operation and
eliminate any resonance.
Installation Instructions:
1. Choose the inlet location within the already heated room and cut a 155mm Dia.
hole. CARE MUST BE TAKEN TO CUT AN ACCURATE AND NEAT HOLE.
Mount the eggcrate inlet grille using the screws supplied.
2. Choose the outlet location in the room to be heated. Cut a 150mm Dia. hole for
the diffuser. Remove the clip-in centre portion of the circular diffuser and the
clamp ring. The diffuser is inserted into the cavity and fixed using the screws
provided. The clamp ring is not normally required. However should you have
difficulty with screwing into the Gib, use the clamp ring over the spigot. Screwing
through the Gib into the clamp ring will produce a secure fixing for the diffuser.
3. Fitting of ducting: Straight runs without tight bends are most efficient. The inner
duct should be stretched reasonably tight to assist efficient airflow. Where joins
in ducting on longer runs are necessary we advise the use of a proper duct
connector sleeve (Order code: DCT0059) to form the joint on. Stretch insulation
over maximum amount of each joint to avoid heat-loss.
4. Locate the best mounting place for the fan unit in the ceiling space. Ensure the
correct airflow direction is maintained when mounting the fan. Make the wiring
connections. It is recommended all wiring be performed by or in conjunction
with a registered electrical contractor. Note that a suitable junction box will be
required to connect the fan and incoming supply.
