Let professionals install your expensive equiptment

 THIS PICTURE shows a tankless waterheater - which has its exhaust flue entering the chimney and joining the furnace  -  THIS INSTALLATION WILL VERY LIKELY BE AT ODDS WITH LOCAL GAS FULED APPLIANCE REGULATION AND THIS WAS SPECIFICALLY NOT CORRECT AS PER MANUFACTURERS INSTALLATION INSTRUCTIONS. 
TANKLESS WATER HEATERS ARE ( ALMOST ALWAYS ) TO BE VENTED DIRECTLY TO THE EXTERIOR AND MOUNTED TO AN EXTERIOR WALL.  THE CONCERN IS BACKDRAFTING ( FORCING EXHAUST GASES TO BACK UP INTO THE HOME = ( READ CARBON MONOXIDE )
