LDK Linear Duct Kits

Installation Instructions

CSA approved for use with Valor Linear Models 1500J, 1700J & 1800J Heaters ONLY

for LDK1, LDK2, LDK3, LDK4, LDK5 & LDK6 Kits

Note: This kit must be installed by a qualiﬁed

installer, service agency or gas supplier at

the time of the heater installation. These

instructions are to be used in conjunction with

the ﬁreplace main installation instructions.

INSTALLER

Leave this manual

with the appliance.

CONSUMER

Retain this manual

for future reference.

Application

This optional convection duct kit redistributes the warm

air ﬂow away from the ﬁreplace opening to a more

desirable location using natural convection without

use of a fan. The warm air ﬂow may be relocated to

a position higher up the wall, out the sidewalls, or

even to another room. The result is much cooler wall

temperatures above the ﬁreplace opening for locating

televisions, artwork, etc.

The 1595CFK Circulating Fan Kit is not recommended

when installing the LDK Linear Duct Kit.

Any kit, LDK1, LDK3 or LDK4 may be used with any of

the listed model ﬁreplaces.

As a further option, the warm airﬂow 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 “J” series Linear

ﬁreplaces only. Earlier version ﬁreplaces will not accept

the addition of this kit.

Note: These instructions are to be used in conjunction

with instructions supplied with the ﬁreplace. Note, the

ﬁreplace requires the removal of the internal

convection bafﬂe for this system to function

properly—read instructions carefully.

The use of this kit will permit lower mantel clearances

to be used—see page 9. These lower mantel

clearances must only be used when the LDK Duct

system is installed.

Approvals

The LDK1, LDK3, LDK4 duct kits are CSA approved

for use only with Valor Linear Series ﬁreplaces listed

above—DO NOT use with any other models.

5-inch diameter duct (not supplied) 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.

Kits

There are 3 kits to choose from:

• LDK1—48” Plenum

• LDK3—14” Plenums (2), includes grilles

• LDK4—38” Plenum

Optional accessories

• LDK2—48” Finishing Frame, to use with LDK1

• LDK5—38” Finishing Frame, to use with LDK4

• LDK6— 5” dia Aluminum 2-ply Flex Kit—

2 x 10’–0” lengths, may be cut to required length

WARNING

DO NOT cover or place objects in front

of the air outlet(s).

WARNING

Minimum clearance below the ceiling is 2-1/2”.

Note that staining or streaking may occur on

light colored ceilings due to any dust, etc. in air

ﬂow; placing the plenum(s) lower on the wall

will help reduce the possibility of staining or

streaking.
