ROctober 24, 2011 Page 23Castile & Santa Fe CE Pellet Stove7068-112BVent ConfigurationsTo reduce probability of reverse drafting during shut-downconditions Hearth & Home Technologies strongly recom-mends:• Installing the pellet vent with a minimum vertical runof 1.52m. Preferably terminating above the roof line.• Installing the outside air kit at least 1.22m below thevent termination.To prevent soot damage to exterior walls of the house andto prevent re-entry of soot or ash into the house:• Maintain specified clearances to windows, doors andair inlets, including air conditioners.• Vents should not be placed below ventilated soffits.Run the vent above the roof.• Avoid venting into alcove locations.• Vents should not terminate under overhangs, decksor onto covered porches.• Maintain minimum clearance of 152mm from the venttermination to the exterior wall. If you see depositsdeveloping on the wall, you may need to extend thisdistance to accommodate your installation conditions.Negative pressure results from the imbalance of air avail-able for the appliance to operate properly. It can be stron-gest in lower levels of the house.Causes include:• Exhaust fans (kitchen, bath, etc.)• Range hoods• Combustion air requirements for furnaces, water heatersand other combustion appliances• Clothes dryers• Location of return-air vents to furnace or air conditioning• Imbalances of the heating/cooling air handling system• Upper level air leaks such as:- Recessed lighting- Attic hatch- Duct leaksWARNING! Risk of Asphyxiation! Negative pressure cancause spillage of combustion fumes and soot.C. Negative PressureNOTICE: Hearth & Home Technologies assumes noresponsibility for the improper performance of the chimneysystem caused by:• Inadequate draft due to environmental conditions• Downdrafts• Tight sealing construction of the structure• Mechanical exhausting devicesD. DraftTo minimize the effects of negative air pressure:• Install the outside air kit with the intake facing prevailingwinds during the heating season• Ensure adequate outdoor air for all combustion appliancesand exhaust equipment• Ensure furnace and air conditioning return vents are notlocated in the immediate vicinity of the appliance• Avoid installing the appliance near doors, walkways orsmall isolated spaces• Recessed lighting should be a “sealed can” design• Attic hatches weather stripped or sealed• Attic mounted duct work and air handler joints and seamstaped or sealedOn nominal heat output the combustion blower operates at2053 rpm developing 0.33 m^3/s. This is the minimum require-ment for the supply of combustion air.Draft is the pressure difference needed to vent appliancessuccessfully. When an appliance is drafting successfully, allcombustion byproducts are exiting the home through thechimney.Install through the warm airspace enclosed by the buildingenvelope. This helps to produce more draft, especially dur-ing lighting and die-down of the fire.Considerations for successful draft include:• Preventing negative pressure• Location of appliance and chimneyTo measure the draft or negative pressure on your applianceuse a magnahelic or a digital pressure gauge capable ofreading 0 - .13mm of water column (W.C.).The appliance should be running on high for at least 15minutes for the test.With the stove running on high you should have a negativepressure equal to or greater than the number given in thechart below. If you have a lower reading than you find on thechart, your appliance does not have adequate draft to burnthe fuel properly.Minimum Vacuum Requirements: .095
