Appendix D—HeatShift System
Application
The HeatShift™ system redistributes the warm air
ȵ
ow
away from the
ȴ
replace opening to a more desirable
location using natural convection without use of a fan.
Plenums LKD1, LDK3, LDK4 or LDK9:
the warm air
ȵ
ow
is relocated to a position higher up the wall, out the
sidewalls, or even to an adjacent room.
Termination Plates LDK7:
the warm air
ȵ
ow is
discharged through a gap (min. 2-1/2”) between the wall
above the
ȴ
replace and the ceiling.
LDK7’s discharge
opening must be located in the same room as the
fireplace.
The result is much cooler wall temperatures above the
ȴ
replace opening for locating televisions, artwork, etc.
The 1595CFK or 1595CFKV2 Circulating Fan Kit are not
recommended when installing the HeatShift system.
Any kit, LDK1, LDK3, LDK4, LDK7 or LDK9 may be used
with compatible model
ȴ
replaces L1, L2 or L3 listed
above.
As a further option, the warm air
ȵ
ow may be extracted
away from the duct kit plenum
(LDK1 and LDK4 ONLY)
by connecting a 1270RBK Remote Blower Kit to the duct
kit plenum.
This kit is compatible with the listed
ȴ
replaces only.
Earlier version
ȴ
replaces will not accept the addition of
this kit.
Note: These instructions are to be used in conjunction
with instructions regarding
ȴ
replace installation in this
manual.
Planning Installation: Linear with HeatShift
™
Instructions for use with the following
Valor Heater Models: 1500, 1600, 1700 and 1800 J or K
Incompatible
with earlier models: 1500I, 1600I, and 1700I
Ʉ
WARNING
DO NOT cover or place objects in front of
or on top of air outlet(s). AVOID locating
outlet within 7 feet above
ȵ
oor level as
discharge temperatures are hot!
Ʉ
WARNING
When placing discharge close to ceilings,
staining or streaking may occur on light
colored ceilings due to any dust, etc. in air
ȵ
ow; placing plenum(s) lower on the wall
will help reduce the possibility of staining
or streaking.
Ʉ
WARNING
All
ȴ
replaces listed above
require the
removal of the internal convection
ba
ɞ
e
for this system to function
properly—read instructions carefully!
The use of this kit will permit lower mantel clearances
to be used—see
Combustible Mantel Clearances
in this
Appendix. These lower mantel clearances
must ONLY
be used when the HeatShift system is installed
and
the internal convection baffle has been removed
.
Approvals
The LDK1, LDK3, LDK4, LDK7 and LDK9 duct kits are
CSA approved for use only with Valor Series
ȴ
replaces
listed above—DO NOT use with any other models.
This HeatShift system may also be used to reduce
wall surface temperatures on approved outdoor
installations.
5-inch diameter duct used with this kit must be metal
and meet requirements of UL-181 Class 1 Air Duct.
Flexible aluminum duct is acceptable provided it meets
the UL-181 Class 1 requirements.
