Typical Domestic Installations - Ceiling Vs Wall - iLO Si Series User And Installation Manual

Note: Single person installation is possible by using temporary "s" hooks (obtained locally) in the
"boxed hook" (left-hand side) of the mounting bracket and the holes in the reinforcement
bars. These hooks replace the helper in step 5 above. These hooks temporarily suspend
one end of the panel while the electrical connections are made. To remove the hooks simply
shake the panel and the hooks will drop out. Then install the panel as outlined above.
The Si Series far infrared heating panels may be suspended from joist or rafters by steel cables or
chains in a manner compliant with local building codes. It is not advised to use nylon or
polyethylene cord to suspend the panels as these materials are flammable.
When mounting the panels on conventional ceilings local building codes may require additional steel
cables, or chains to secure the panels to the rafters or joists above. Wires, cables and/or chains may
be secured through the appropriate size holes at the ends of the panel's mounting brackets.
Please contact your Spectrum Infrared representative for further advice on mounting panels,
thermostats and/or control systems.
CAUTION! To minimize the risk of fire and to prevent the undesired loss of performance (caused
by voltage-drop) do not use extension cords to power the heaters.
9. Typical Domestic Installations – Ceiling vs Wall
• IR Panels mounted on ceilings for highest efficiency. The ideal panel installation
minimizes convection at the panel, and maximizes Infra-Red emission. Convection
depends on the flow of air close to the panel surface, and so the simplest way to minimize it
is to use the panel itself as a barrier to air movement – see Figure 9b.
• When installed as shown in Figure 9a (Horizontal, at ceiling height), the full benefits of
the Si Series heating panels will be obtained. The layer of trapped air stays close to the
panel, and consumes little power.
• Wall mounted panels can lead to greater heat losses to outside walls.
• Independent tests have shown 20% lower heat losses/better efficiency with ceiling
mountings.
