The restrictor plate is to be used only in a completely vertical vent
installation. The restrictor plate can be used when the vertical vent
rise is between 10 feet and 25 feet.
In a vertical vent rise the rear (yellow) flames on the main burner
can be reduced due to the drawing action from the flue exhaust pipe
and the air inlet pipe. A decrease in the height or the appearance of
the yellow flame may occur when the vertical vent rise is between
10 feet and 25 feet. To enhance the yellow flame on the main
burner, the restrictor plates need to be installed on both air inlet
holes behind the log shelf.
Please use the following steps to install the restrictor plate.
1. Remove cast iron top and carefully set aside.
2. Remove cast iron front and carefully set aside.
3. Carefully remove glass door.
4. Remove the log shelf by removing the (2) screws securing the
log shelf to the wall.
5. Loosen the upper (2) screws of both air inlet holes.
6. Slide restrictor plates down over loosened screws. Tighten (4)
screws securely.
7. Modify log shelf by bending tab on front edge flat for LP or
down for Natural gas.
8. Replace log shelf carefully by replacing the (2) screws.
9. Carefully replace glass door.
10. Replace cast iron front.
11. Replace cast iron top.
12. Installation of restrictor plate is completed.
Attention:
Restrictor plates for Natural gas have diamond shaped
notches for mounting on screws. LP gas plates have square shaped
notches for mounting on screws. Be sure to use the proper restrictor
plate for the gas type.
