(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 flame pattern. Pull the rod out
until the flame 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 0.14 - 0.15 inches of water column (34.8 - 37.3 Pa)
on the high fire setting. Some fuels may require higher or lower
settings.
The reading can be taken from the 1⁄8” (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 1⁄2” (12mm) in from the inner mark from step #5
8. Re-install the cabinet side.
9. Install a set collar on the outside of the outer mark from step #5
