💡 What diameter flexible thermal liner performs best in tall masonry chimneys?
Sizing the correct tube guarantees optimal draft velocity while protecting interior mortar from acidic condensation and heat loss. Proper alignment keeps combustion gases moving fast enough to stay dry and efficient during freezing winter conditions. You should measure the internal clearance of your brick channels before feeding down the coil because flexibility only works smoothly when the shaft remains unobstructed.
- Check the internal cross section of your flue to confirm eighteen inches of space around the insulated coil - Feed the flexible tube downward until the mounting plate sits flush against the rain cap bracket - Attach the appliance connector using the steel band clamp and high temp sealant tape - Light a low fire for twenty minutes to cure the spray adhesive before full household heating
