Leyden Wood Stove Stainless-Steel Bypass
Rod

Compatibility
This kit is for Leyden wood stoves with a warped or bent bypass rod. Because the rod is not
visible inside the firebox, the only way to determine if the rod is warped is the tensioner bolt. If
the bypass does not stay shut, and the tensioner bolt is screwed fully in*, the bypass rod is likely
warped and will need to be replaced.
This kit contains an improved bypass rod made of stainless steel. This improvement is in all
Leydens manufactured after 2/16/2007 (Rev 002). If you are uncertain if the bypass rod is
stainless-steel, remove the bypass handle and check the rod. If it is stainless-steel a magnet
will not stick to the rod.
The tensioner bolt should be 1” long to provide the necessary adjustment on the bypass rod
assembly. If the installed bolt is too short, replace it with an included 1” bolt and test bypass
adjustment. NOTE: The bypass rod may be warped by the tensioner if this bolt is over-tightened
repeatedly (the tensioner deflects the rod until it starts to bend). When adjusting the tensioner
bolt, tighten it only enough to keep the bypass shut without excessive effort on the bypass
handle.

3 Remove the back heat deflector and place it aside (the allows for access to the nuts that hold the firebox back
plate in place).
4 Remove the back brick retainer holding the back brick in place (“U” Brick).
NOTE: The ½” bolts holding the retainer in place are used only to hold the brick in place. If one of these
bolts breaks off, we recommend that you leave the threaded portion inside the cast iron damper
assembly. Two bolts are sufficient for holding the retainer in place. We have included two 10-24 3/8”
screws if additional fasteners are required (use an 11/64” drill for pilot holes).
NOTE: When replacing the retainer, use the included ½” ¼-20 bolts included with this kit.
Three bolts hold the
back brick retainer in
place.

When removing the damper assembly, take care to not damage the combustor.
NOTE: If either of the bolts holding the damper assembly breaks off, use the included #7 drill bit to drill out
the broken bolt (drill from the back side). If the threads on the stove are damaged while drilling, drill
out the hole with the 9/32” drill bit and secure the assembly with the extra 1-1/4” bolts and nuts
included with this kit.
The damper may swing
open while removing
the damper assembly.
Use both hands to
secure the damper.

9 Remove the bypass handle (use a 1/8” hex wrench).
10 Remove the clip on the right side holding the damper rod in place.
NOTE: If this bolt breaks off, use the included #7 drill bit to drill out the broken bolt. If the threads on the
stove are damaged while drilling, drill out the hole with the 9/32” drill bit and secure the assembly with
the extra 1” bolt and nut included with this kit.

11 Slide the damper rod down and to the right to remove it from the appliance.

15 Re-attach the damper handle. Position the damper so it is angled slightly forward. This will help during re-
installation of the damper assembly.
16 Replace the tensioner bolt on the damper assembly (the upper bolt on the damper plate) with the included 1”
bolt and nut. The bolt should be inserted so it does not tighten against the tensioner plate. Tighten the nut
against the damper plate to insure the bolt does not back out.

17 Replace the damper assembly. While positioning the assembly, hold the damper slightly open, this allows the
rod to slide over the ramp on the damper.
While installing the
damper assembly the
damper rod will slide
over this ramp.

18 Secure the damper assembly (use the included ¼-20 nuts and ¼-20 1-1/4” bolts, do not use the nuts and bolt
that were removed from the stove).
19 Test operation of the damper before replacing the other components. The tensioner bolt will probably need to
be backed-out fully for the bypass to operate.
20 Replace the stove components (use the included ¼-20 nuts and ¼-20 bolts, do not use the nuts and bolt that
were removed from the stove). Use the included gaskets during re-assembly.
