Chalet 1800 Ins

FULL LINER INSTALLATION

There are different ways of installing a full liner, you can drop it in from the top or bring it up from
the bottom.
In the USA, in order to meet the requirements of UL 1777, you may have to insulate your liner and
if you do, it will have to be done as a system to manufacturers certified installation instructions.
In Canada, you can run  ULC S635 or ULC S640 liner systems. If you would like to obtain a sys-
tem with certified reduced clearances, there are manufacturers who have tested their ULC S640
liners  for  close  clearance  and  even  zero  clearance  to  combustibles  using  their  own  insulation/
installation requirements which must be adhered to. As Archgard has no control over what liner
system  is  being  used with  the  CHALET  1800 WOOD  Fireplace Insert,  here  we  can only  give  a
general overview of the installation procedure of dropping a generic uninsulated liner  from the top
of the chimney and connecting it to the flue collar of the appliance.

It is of the utmost impor-

tance that the installation instructions of the liner system that you will be using be con-
sulted when doing your installation.

1. If you will be doing any modifications to the damper assembly or to the back wall or smoke

shelf (first check if you are allowed to do so), to accommodate the liner, now would be a good
time to so and to fasten the permanent warning label, that comes with the insert, to the back
wall of the fireplace warning future owners that the fire-
place may have been altered to do this installation, in
the event that the insert is ever removed.

2. Drop the liner down from the top of the chimney. If it is

a tight fit or if offsets are present, you may have to at-
tach a cone to the end of the liner with some rope com-
ing out the end of it or just squeezing the ends of the
liner together and duct taping some rope to the end it.
Drop the rope down and with someone at the bottom
pulling on the rope and someone at the top pushing on
the liner, it should get to the bottom.

3. When it gets past the smoke shelf (you may have prob-

lems getting the liner past this point,  you may have to
order  an  ovalized  liner  or  you  may  wish  to  ovalize  a
section of liner yourself.  If you ovalize it yourself, check
with the liner manufacturer to see if they will honor any
warrantees if

you

ovalize the liner. If you aren’t careful

or don’t have the equipment, you could damage the

liner when you ovalize it), if you squeezed the ends of
the liner, cut the damaged ends off with a knife and tin
snips. If an adapter is being used, rivet it onto the flex
liner  now.  Rivets  work  better  on  thin  liner  because
screws  tend  to  work  their  way  out  (loosen  out)  but  if
you  use  rivets,  make  sure  you  use  rivets  that  are
marked SSSS for Stainless Steel Shank and Stainless
Steel  Rivet.  If  you  use  rivets  that  just  say  SS  then  all
you are getting is a Steel Shank and Steel Rivet and they will corrode  in a short time.

NOTE:

a) masonry or steel shall not be removed from the fireplace to accommodate the appli-

ance; (b) masonry or steel, including the damper plate, may be removed from the smoke shelf

and adjacent damper frame if necessary to accommodate a flue liner, provided that their removal

will not weaken the structure of the fireplace and chimney and will not reduce protection to com-

bustible materials.
