4 irect Vent irectvent Pro Planning Your Installation For vertical gas stove installations, measure the height from the stove outlet to the ceiling to determine the length of black pipe required. Select a ceiling support/wall thimble cover or a cathedral ceiling support box. To determine the length of galvanized pipe required, measure the ceiling thickness and the vertical rise in an attic or second story. Firestops are required at each floor level beyond the first floor ceiling support/wall thimble cover or cathedral ceiling support box. If an offset is required to avoid obstructions, use a pair of 4 elbows. For proper support, use elbow straps with offsets. Use wall straps for long vertical runs. ttic Insulation Shield is required in attic. Measure the roof pitch. Select the proper flashing and storm collar. etermine the minimum height above the roof. For horizontal installations, check the appliance manufacturer s instructions for minimum rise and maximum horizontal run. snorkel termination may be used if height restrictions prevent adequate rise above the appliance.
