FIREPLACE INSTALLATION
STEP 6: CHIMNEY ASSEMBLY
SOLID BLOCK CHIMNEY
FireRock Solid Block Chimney (Figure 8.1) is installed
next.
For 30” and 36” fireplaces, 2’ of chimney block (4 pieces)
have been provided. For the 42” unit, 3’ (6 pieces) have
been included in your kit. Additional chimney block can be
added to achieve the desired height as long as maximum
heights are followed (see page 6).
Completely cover each chimney block component with 1/2”
- 1” of mortar, resulting in a 1/16” - 1/8” joint. “Butter” all joints
to give a smooth appearance and ensure a leak-free joint.
The inside face of the chimney should also be “buttered”
to ensure a no-leak seal, as well as to prevent smoke
obstruction caused by excess mortar build up.
For masonry chimney, mortar should be used at a rate of 1
bag for every 6 blocks.
