Restrictor Usage / Troubleshooting / Installation / Modification - kozy heat 911XL Installation And Operation Manual

RESTRICTOR USAGE:
Turn the fireplace on and allow to burn for 15 minutes. If flames indicate there is excessive draft (flickering, short flames) or insufficient draft
(lifting or ghosting flames) a restrictor may be necessary, or the previously installed restrictor may need to be modified or removed.
WARNING: TO AVOID PROPERTY DAMAGE OR PERSONAL INJURY, ALLOW FIREPLACE INSERT AMPLE TIME TO COOL
BEFORE MAKING ANY 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 it is determined that the venting is correct and the restrictor has been removed, yet the flames are still lifting or ghosting, shut
off gas supply to fireplace insert and call a qualified service technician.
RESTRICTOR INSTALLATION / MODIFICATION
If it is determined that a restrictor is needed or restrictor modification is required after the termination is installed, access can be reached through
the fireplace insert baffle. Please remove logs and refractory to avoid damaging these components.
1. Remove (2) nuts securing baffle. Remove baffle to expose venting.
2. Depending on your specific needs, determined by the chart above along with other factors, make necessary modifications.
3. If installation of a restrictor (included in components packet) is necessary, bend tabs on restrictor to approx. 80 degree angles to create ten-
sion when inserted into the exhaust pipe on fireplace insert. Insert restrictor into 4" exhaust pipe with tabs pointing towards you.
4. If modification is necessary, remove restrictor by pulling it down and out of 4" exhaust pipe.
5. Reinstall baffle, secure with (2) nuts previously removed.
6. Reinstall refractory and log set.
7. Attach glass frame assembly and light fireplace. Wait 15 minutes before determining if any further modifications are necessary.
Remove nuts securing baffle, remove baffle to expose venting.
