INSTALLATION INSTRUCTIONS

CAUTION: Each installation must conform to all local, state and national codes. Refer to the national fuel gas code and local zoning and code authorities for details on

installation requirements. The Mendota Inserts must be vented to the outside in accordance with the latest edition of the National Fuel Gas Code. In the absence of local

codes, the installation must conform with National Fuel Gas Code ANSI Z223.1 (NFPA 54), or Canadian Code CAN1-B149 or most current edition, also known as

NFPA 54. Do not connect this Insert to a chimney flue serving a separate solid fuel or gas-burning appliance.

1. Remove glass doors, metal fire screens, etc. from existing fireplace. Be sure there is 12" minimum dis-

tance from top of upper grill to bottom of mantel; see Specifications (Pg.6 & 5), and a 16" minimum non-

combustible hearth extension in front of the glass surface if a raised hearth is not supplied. (See pg. 11

for "Raised Hearth").

2. Remove any additional framework or other obstructions in the existing fireplace opening and burning area.

Also remove any chimney cap from top of chimney so that vent liner can be installed freely.

3. Before Insert is installed, have gas supplier or contractor run gas line to the existing fireplace. Be sure gas

plumbing instructions [see Pg. 12 & 13 are carefully followed. Gas supply may enter fireplace on either

side or back of fireplace, whichever is most convenient and accessible. Electrical service (120 volt) should

also be supplied.

4. The entire chimney should be swept to remove creosote, soot and any obstructions (bird nests, etc.).

5. Open fireplace damper. If damper opening is large enough to accept the 4" and 3" flue liners, permanent-

ly secure damper in "open" position. NOTE:

Massachusetts requires that the flue damper must be re-

moved or permanently welded in the "open" position.

6. If damper opening is too small for the 4" & 3" flue liners, it will be necessary to remove the damper handle

and the damper plate. Some damper plates are held in place by a pinned hinge that can be released easily

by tapping out the pin with a hammer and punch. Others may be held in place by a screw or bolt, or pi-

vots may be cast into the damper housing. The latter types may be harder to get out and may require

sawing or breaking out. [NOTE: if flue size is 6" (127 mm) or less, or if severe offsets occur, or a signifi-

cant mortar slop is evident between the liners, try to snake liner down the chimney to the top of the dam-

per housing before breaking out damper plate and housing.]

CAUTION: If the 4" & 3" flue liners cannot be installed in an extremely tight chimney DO NOT proceed

with installation.

7. If damper opening is narrower than 4-1/2" to 5" (114 mm to 127 mm) and if local code authorities allow,

loosen and remove mortar behind back side of damper housing in the center of the opening enough to get

the gripping teeth of a pipe wrench over the flange of the damper housing (for cast iron housings). Tigh-

ten the wrench snugly, and kick down on the wrench handle to break out a half moon shaped piece of the

damper housing, enough to easily fit the flex liner through it. If the opening is wide enough, the break out

is not necessary.

8. Install Insert only in chimney heights of 12' (minimum) to 35' (maximum) -- as measured in

step 9, below.

9. Measure the chimney height from the top of the chimney (or the existing flue liner) to a point 24" (610

mm) above the floor of the fireplace hearth. It may be necessary to drop a rope and measure the rope it-

self. Be sure to allow for all offsets in existing chimney. Cut the 4" diameter flex liner (s) to this measured

length.
