Flue Restrictor Instructions
1. Remove the top piece of refractory, if already installed.
See Figure 4.14.
2. Orientate and align the two pieces of the flue restrictor
as shown in Figure 4.16.
3. Match the amount of vertical you have in the system
with the chart to find the appropriate position to set the
flue restrictor. See Figure 4.15 and 4.16.
4. Center the two flue restrictor pieces on the vent at the
setting selected in step 3 and secure in place by using
two self-tapping screws. See Figure 4.14.
