Restrictor Troubleshooting / Installation After Termination Completion - kozy heat SLA-42 Installation And Operation Manual

FINALIZING THE INSTALLATION
RESTRICTOR USAGE:
Turn fireplace on and allow to burn for 15 minutes.
If flames indicate there is excessive draft (flickering, short flames), a restrictor may be necessary.
If flames indicate insufficient draft (lifting or ghosting flames), a previously installed restrictor may need to be modified or removed.
TO AVOID PROPERTY DAMAGE OR PERSONAL INJURY, ALLOW FIREPLACE AMPLE TIME TO COOL BEFORE MAKING ANY
WARNING
ADJUSTMENTS AND / OR INSTALLATIONS.
FLAME APPEARANCE
Short, flickering
Lifting or ghosting*
* Improper venting installation may cause flames to lift or "ghost" - a dangerous situation. Inspect flames after installation to ensure proper
performance. If determined that venting is correct, and the restrictor has been removed, yet flames are still lifting or ghosting, shut off gas
supply to fireplace and call a qualified service technician.
RESTRICTOR INSTALLATION / MODIFICATION
If it is determined that a restrictor is needed or restrictor modification is required after termination is installed, access can be reached
through the fireplace baffle.
1. Remove glass frame assembly. Page 15.
2. Remove (2) screws securing termination access panel. Release panel tabs from slots in baffle.
3. Depending on your specific needs, determined by chart above along with other factors, make necessary modifications.
4. If installation of a restrictor (included in fireplace components packet) is necessary, bend tabs on restrictor to approx. 80 degree angles
to create tension when inserted into exhaust pipe on fireplace. Insert restrictor into 5" exhaust pipe with tabs pointing towards you.
5. If modification is necessary, remove restrictor by pulling it down and out of 5" exhaust pipe.
6. Reinstall termination access panel, inserting tabs in panel into slots in baffle. Secure with (2) screws previously removed.
7. Re-install glass frame assembly and light fireplace. Wait 15 minutes before determining if any further modifications are necessary.
