1. To install the optional slider damper
rod remove the left cabinet side
panel. Partially back out the two (2)
T-20 Torx screws on the back of the
each panel and the two (2) located
on the front inside edge below the
louvers and ash shelf. Pull the panel
forward then remove and locate the
slider damper plate.
2. Install the
7
/16” (11mm) nut onto the
slider damper rod, thread it all the
way onto the rod.
3. Slide rod through the hole in the
slider damper plate and install the
7
/16” (11mm) clinching nut onto
the rod. Leave nut a little loose to
help it line up when the cabinet is
re-installed.
4. Re-install the cabinet side.
5. Mark the rod at either end of range
in which the unit runs correctly and
has a good ame pattern. Pull the
rod out until the ame becomes a short, brisk flame, like a blowtorch;
push the rod in a little and mark it. The next mark its the most important
and is set with a magnehelic.
IMPORTANT: Taking a reading of vacuum pressure inside the firebox with
a magnehelic gauge should be used to set the slider for best combustion.
The slider damper should be set only on a hot stove (operating for thirty
(30) minutes or more) by using a Magnahelic Pressure Gauge to measuring
the pressure in the firebox. The best settings are a reading of
approximately 0.15 - 0.17 inches of water column (29.9 - 37.3 Pa)
on the high fire setting. Some fuels may require higher or lower
settings. The reading can be taken from the ⅛” (3 mm) hole located on
the front of the unit below the ash shelf on the right hand side.
6. Remove the cabinet side
7. Install a set collar ½” (12mm) in from the inner mark from step #5
Figure 20: Efficient Flame.
8. Re-install the cabinet side.
9. Install a set collar on the outside of the outer mark from step #5
10. Install the black knob on the end of the rod. Check slider damper for smooth operation.
