Vent Restrictors
A vent restrictor is a metal plate that reduces the flow of exhaust evacuating the fireplace. A restrictor is only necessary when the
flame is receiving too much oxygen. Various-sized restrictors are supplied with every fireplace. See instructions below to determine
which restrictor, if any, is recommended for your fireplace.
Restrictor Sizing Guidelines
The restrictor sizing tables in this section determine the recommended restrictor for your vent configuration. These tables show Ortal’s
recommendations only. The Environment, gas type and other factors may affect the best restrictor choice.
How to use the “Recommended Restrictor” tables:
1. Find the total vertical rise in your vent configuration along the y-axis.
2. Find the horizontal run in your vent configuration along the x-axis.
3. Follow the desired rise and run values within the table until they meet. This value is the recommended restrictor size (in
inches) for your vent configuration.
Legend:
X: Vent configuration is not allowed. Power vent required.
0
: No restrictor required.
Numbers other than 0: Represents the recommended restrictor (by width).
