Only listed wall pass throughs and fire stops may be used See NOTES on page 12 Design The first thing needed is deciding where and how the furnace will be installed Things that need to be taken into consideration are Venting Supply and Return Ducting Electrical and Condensation Drainage if A C is installed Don t forget access to the furnace for service When the return air inlet position is known the filter box and distribution blower can be installed After the furnace is set into place the venting can be completed Venting Use 4 pellet vent pipe only A combustion blower is used to extract the combustion gases from the firebox This creates a negative pressure in the firebox and a positive pressure in the venting system as shown in fig 2 The longer the vent pipe and more elbows used in the system the greater the flow resistance Because of these facts we recommend using as few elbows as possible and 30 feet or less of vent pipe The maximum horizontal run should not exceed 18 feet Remember the horizontal pipe sections will accumulate with fly ash first Keep this area clean Be sure to use wall and ceiling pass through fittings which are approved for pellet vent pipe when going through combustible materials Be sure to use a starting collar to attach the venting system to the furnace The starting collar must be sealed to the furnace flue collar with high temp silicone caulking or aluminum tape and
