Techgrille are recommended If the floor is the only option available then special care should be taken in locating grilles Areas such as under baseboard heaters will help to temper the air Also optional inline duct heaters are available for mounting in the supply duct work to add heat if required In homes with a forced air furnace you may want to connect the HRV ERV to the furnace ductwork see information below Direct Connection to Furnace Ductwork Should you wish to hard duct the supply air directly into the cold air return of the furnace remember to check the air flow balance of the HRV ERV with the furnace fan both ON and OFF to determine that it does not imbalance the unit more than 10 Also it is advisable to include a short length of fabric flex duct or other non metallic connector in this hard ducted line in order to keep the HRV ERV separately grounded electrically from the furnace This will avoid a possible shock hazard to service people if a short to ground develops in one of the devices Indirect Connection to Ductwork If permitted by local codes an indirect connection may be made between the HRV ERV supply duct and the furnace return plenum The fresh air from the unit may be directed at a grille installed in the cold air return duct of the furnace The fresh air supply outlet from the unit should be no closer than 4 inches 100 mm and no more than 12 inches 300 mm from the grille Stale Air Exhau
