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 (refer to 13.1.1, Remove Glass Frame Assembly, on page 29) and safety barrier.
2. Remove (2) screws securing termination access panel. Release panel tabs from slots in baffle.
3. Depending on your specific needs, determined by Table 18.3, along with other factors, to make necessary modifications.
4. If installation of a restrictor (included in fireplace components packet) is necessary, bend tabs on restrictor to approximately
80
°
angles to create tension when inserted into exhaust pipe on the fireplace. Insert the restrictor into 5 in. exhaust pipe
with tabs pointing towards you.
5. If modification is necessary, remove restrictor by pulling it down and out of 5 in. 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 (refer to 13.1.2, Install Glass Frame Assembly, page 29), and safety barrier, then light the
fireplace. Wait 15 minutes before determining if any further modifications are necessary.
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
.
Table 18.3, Restrictor Troubleshooting
Flame Appearance
Draft Problem
Restrictor Solution
Short, flickering
Excessive draft - not enough restriction
Add restrictor
Lifting or ghosting*
Insufficient draft - too much restriction
Remove inner ring(s) on restrictor or
remove restrictor
*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.
