Restrictor (Troubleshooting And Installation After Termination Completion) - kozy heat DASSEL DSL-36 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 (recommended on
all vertical terminations over 6‟ (1.82 m )) may need to be modified or removed.
WARNING: TO AVOID PROPERTY DAMAGE OR PERSONAL INJURY,
ALLOW FIREPLACE 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 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 baffle. Please remove logs and optional refractory (if installed) to avoid damaging these components.
1. Remove the (4) screws 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 fireplace components packet) is necessary, bend tabs on restrictor to approx. 80 degree
angles to create tension when inserted into the exhaust pipe on fireplace. Insert restrictor into 5" exhaust pipe with tabs pointing
towards you.
4. If modification is necessary, remove restrictor by pulling it down and out of 5" exhaust pipe.
5. Reinstall baffle, securing with the (4) nuts previously removed.
6. Reinstall log set and optional refractory kit (if installed).
7. Attach glass frame assembly and light fireplace. Wait 15 minutes before determining if any further modifications are necessary.
