Halcyon Gas Fireplace EuropeanHome.com27INSTALLATION - VENTING9. CONFIGURING THE VENTINGThis section provides venting information which is specific to the Halcyon Gas Fireplace.The Halcyon Gas Fireplace is a direct vent fireplace that uses a co-axial or “pipe within a pipe” venting system. The outer “pipe”or vent (8” diameter) conducts outside air into the Fireplace and the inner vent (5” diameter) carries the exhaust outside. Thistechnology, which can run either horizontally through a side wall or vertically through the roof, produces an efficient systembecause conditioned building air is not used for combustion.All of the following bulleted points apply to every installation:• The Halcyon Gas Fireplace requires 5”/8” direct vent components from any of the manufacturers listed in Table 8. Approvedterminations are also listed in Table 8.• All measurements are taken from the center of the vent connector on the top of the Halcyon cabinet (see Figure 24) and allconfigurations must fall within the acceptable range of Chart 1.• The maximum allowable rise is forty feet and the maximum allowable run is fifteen feet but not in combination; see Chart 1.• The minimum vent configuration is a 12” vertical rise to a 90° elbow plus a 6” horizontal run to a sidewall termination. Thismeans that the first vent section must be a 12”, or longer, vertical section.Figure 24- Maximum Venting40’max.rise15’max.runAPPROVED TERMINATIONS by MANUFACTURERManufacturer Horizontal Vertical SnorkelAmerican Metal Products Group 5DHCS, 5DHC 5DVC —Selkirk Corp. 5DT-HC 5DT-VC, 5DT-VT 5DT-ST14Simpson Manufacturing, Inc. 58DVA-HC 58DVA-VC —Table 8 - Approved Terminations by Manufacturer
