when the material feels damp but still granular
(~7 to 9 gallons of water per bag/box). *When
a handful of properly moistened TherMix is
squeezed hard, little to no water appears
between the ngers.
During the installation, correctly prepared Ther-
Mix pours like “loose ll.” TherMix is distributed
within the chimney cavity by vibrating the liner.
*Do not tamp or compress TherMix.
Roll out the insulation blanket on a clean
surface, foil face down. Lay the ex liner on top
and trim the blanket so that it is about one foot
shorter than the liner.
Wrap the insulation around the liner lengthwise
and trim it so that a butt joint is formed.
Seal the joint with aluminum foil tape. Spray
adhesive may be used to hold the blanket in
place until it can be secured with the foil tape.
A minimum of 1/2" of insulation is required. If a
double layer of blanket is needed, install it with
the butt joint on the opposite side.
Install ProMesh protective wire mesh over the
blanket(s). The ProMesh is used to protect
the ProFoil insulation as the liner is lowered
into the chimney. Slip the ProMesh over the
insulated liner and secure one end with a
stainless steel band clamp. Pull the ProMesh
towards the other end of the liner so that it
tightens snugly around the insulation, then trim
off the excess. Secure this end with a stainless
steel band clamp.
When installing gas or oil appliances, use
connector pipes specically designed for
connecting such appliances. Attach the
connector pipe directly and securely to the Tee
Snout or to a listed wall penetration assembly.
Secure all sections of the connector pipe with
screws or rivets.
Record the date of installation (on the label
provided with the liner) and attach it to the
Tee Snout or wall penetration assembly.
