Restrictor plate
The fireplace is equipped with a factory installed restrictor set at fully
open. If fireplace vent is terminated horizontally, NEVER CLOSE the
restrictor completely. Adjust the restrictor opening by judging flame
characteristics after 20 minutes of burn time (on cold start, for first
few minutes the flames might be blue).
If flames ghost off the burners or if sooting occurs (mostly with propane)
open the restrictor fully and work backwards in increments to determine
the correct position.
FOR REAR VENT RESTRICTOR MUST BE LEFT FULL OPEN.
FOR POWER VENTED UNITS RESTRICTOR MUST BE CLOSED.
For most runs that include lengths of both horizontal and vertical pipe,
especially ones with multiple elbows or long horizontal runs, restrictor
should be full open.
Restrictor opening should be adjusted for long vertical lengths with
short horizontal runs or vertical only runs to reduce flue draft.
Recommended settings for vertical runs (depends on installation
specifics, altitude, fuel and other factors):
• For Verticals 3' to 6' – various between fully open to 1" open
• For Verticals 7' to 10' – 1" open or fully closed
• For Verticals over 10' –fully closed

Primary air adjustment
During initial installation, check primary air opening
(below are factory settings):
DRSQ38*I 3/16" for NG and ½" for Propane;
DRSQ38*I-2 ¼" for NG and full open for Propane.
The primary air might need adjusting from the factory setting for vertical
runs. If flame is sooting, primary air may need to be opened slightly
Smaller primary air opening means yellower flame.
Note: all adjustments to primary air must be made by qualified
installers. Very small changes in opening size make major changes in
flame appearance
Depending on desired flame appearance recommended primary air
adjustment limits: NG ⅛" – ¼" and propane ⅜" – Full open.
