of coils be used with this product. When using 4" or 5"
(102 or 127 mm) diameter duct work, the maximum air
conditioning system size should be limited to 1.5 tons
(18,000 BtuH). When using 6" (152 mm) diameter duct,
air conditioners of up to 2 tons (24,000 BtuH) may be
used. Total static pressure of the system above the out-
let from the fireplace cabinet should not exceed 0.40"
w.c. with the air circulating blower on high speed, when
using the maximum air conditioning capacity.
Two rails come factory mounted in the coil cabinet.
These represent the minimum clearance between the
evaporator coil and the fireplace cabinet top. Do not
mount an evaporator coil below the level of the rails.
Final Finishing
Noncombustible materials such as brick and tile can
be extended over the front face of the unit (Do not
cover louvres or glass door). If a trim kit is going to
be installed, brick and tile will have to be installed flush
with the side of this appliance.
