Approved for use with all Mendota ZC Fireplace models, except M27.
NOTE: This kit must be installed by a qualified installer. These instructions are to be used in conjunction
with the fireplace installation manual to insure proper installation.
These kits are designed to use natural convection to transfer warm air from the front of the fireplace to
a different location. The kits allow the warm air from the fireplace to enter the room farther up on the
fireplace chase front wall or side wall. This results in much lower breastplate, mantel and wall
temperatures above the top convection chamber of the fireplace.

Many television manufacturers specify in their installation instructions that the television must not be installed near or above a heat source. The decision to install a television near or above a Mendota fireplace rests solely on the consumer. It is the consumers responsibility to satisfy television specifications and insure the television will not exceed maximum operation temperatures. - Page 8 The Mendota Cool Wall system uses natural convection to take heat off the wall directly above the fireplace and redirects it up and away from surrounding areas. Testing has shown that when using a Cool Wall system, temperatures above the fireplace are reduced making it possible to mount a television 15”...

- Page 19 6. Next use the flex vent to connect the vent pipe that was installed on top of the fireplace to the starter collars that are located on the vent box. Cut the vent to length and pull it tight between the two connections. Use the 8” hose clamps to hold the flex vent to the starter collars on the vent box and rigid pipe on the unit.
