fireplace insert install question
 

I will be installing wood burning fireplace insert soon. Have never done
this before, and need some advise on couple of things.. Have been looking
for 20' X 6" stainless flex liner kit. So far Chimney liner depot is best
price I have found....$370.00 for basic liner + terra cotta top plate +
appliance connector + rain cap - all stainless steel - price includes
shipping. are there any better options?

The liner will have to pass through the flu damper opening that is 4.5" X
20" so they are saying to ovalize 18" (18" is distance from damper to top
of insert) so it will fit throught opening, then reshape to round then
connect to appliance connector and to top of insert. The sales person I am
talking to also advises me to purchase this material to plug hole where
damper plate has been removed -

- also to wrap arround top of liner then put on terra cotta top plate. The
existiong Terra cotta liner is 7 5/8" X 11 5/8" inside, so not possible to
insulate whole liner. Sales person tells me it is most important to plug
hole arround liner at damper opening. There is a large area between damper
and the beginning of existing terra cotta liner. It is about 30" tall by 20"
wide at bottom (narrows as it goes up) Menards has large bale/roll of non
combustable insulation ( this insulation says non combustable per ASTM E136
on it ) I was thinking this might work better to shove up and fill the
whole area. Does this sound like good idea? Menards clerk says this
insulation is rated for 1200 degrees......but it does not say that on
packaging. I have not been able to find out what means - non combustable per
ASTM E136. From what I have read, the hot gasses from insert can reach temps
of 600 to 800 degrees. Any advise appreciated.

I believe rockwool handles significantly higher temps than that, unless those
are "C" temps.
