Installing The Frame - Spartherm XS 500 Installation And Operating Instructions Manual

 All remaining unfilled (non-airtight) areas - through which "false air"
can enter - are to be sealed using a sealing agent (e.g. rock wool
and, where required, a sheet metal cover).
 Any existing wooden beams in the open fireplace are to be protected
using additional thermal protection (e.g. air deflector plate) when they
are within the thermal radiation field or are located in the area of the
cassette's thermal air convection field. This is particularly important
when the fireplace cassette protrudes out of the existing open fire-
place.
 The changes to the thermal radiation field
when using the fireplace cassette in com-
parison to that of the open fireplace
should be taken into account.

In cassette designs including a hot air blower, it is necessary to
initially remove the rotary knob at the front and unscrew the nut (see
Fig. 7). The speed controller remains in position within the hole.

2.16 Installing the frame

In order to install / dismantle the cassette
frame, the firebox door needs to be
opened to access the four fastening
screws for the frame. The screws must be
turned approx 3-4 times to loosen them.
The frame can then be removed in a
forwards direction. Installation is carried
out in the reverse order.
