(See also the instruction sheet included with the catalytic
combustor kit.)
The (FDCCO) Catalytic Kit of the Opel AP includes:
- Cotter pin
- Template
- Bypass rod
- Bypass damper
- Catalytic bypass frame(with rope seal)
- Catalytic converter
- Tapping screws (10) and washers (2)
- Retaining brackets (4)

Preparation of the fireplace
1. Remove doors and all refractory liners.
2. Lay unit on its back for easier access.
3. Remove the screen above the door opening by remov-
ing the 4 screws in behind (Picture1). If the unit has been
fired already, oil the screws before removing them or
they may break.
4. Remove secondary air tube by removing the screw on
the left side (Picture 2).
5. Remove the baffle. (See instructions on page 8, baffle
removal section.)
6. Break off the baffle support brackets by bending the
brackets up and down with vice grips (Picture 3).
Installation of the catalytic combustor
1.
Hook the template provided into the top louver open-
ing, flush with the right side.
2.
Use a punch to make a mark through the small hole on
the front of the template (Picture 4), then remove tem-
plate and discard. Make a pilot hole at the punch-mark,
then drill a 33/64” hole (Picture 5).
3.
Take the bypass rod and, from inside the fireplace, push
the long end through the hole you just drilled. On the
outside, pull the bar out as far as it will go (Picture 6).
4.
With a cotter pin, connect the bypass rod to the bypass
damper (Picture 7). The bent lip side faces the back of
the unit with the connecting bracket facing up.
5.
Install the new catalytic holder. It only goes in one way
as shown in (Picture 8). The bottom of the catalytic
holder must be at 18 ¾” from the bottom of the firebox
(Picture 9).
