Raypak XFyre 300A Installation & Operating Instructions Manual

This type of installation can cause non-warrantableproblems with components and poor operation of theboiler due to the recirculation of flue products. Multi-ple vent caps installed in the same horizontal planemust have a 4 ft clearance from the side of one ventcap to the side of the adjacent vent cap(s).Combustion air supplied from outdoors must be free ofparticulate and chemical contaminants. To avoid ablocked flue condition, keep the vent cap clear ofsnow, ice, leaves, debris, etc.Condensate ManagementThe condensate must be drained properly to protectthe appliance and drainage system. The condensatefrom the boiler is acidic. Its pH is between 3.2 and 4.5.Raypak recommends neutralizing the condensate witha Condensate Neutralizer kit (Z-12). The neutralizer kitis connected to the drain system and contains lime-stone (calcium carbonate) chips to neutralize the pHlevel of the condensate. The kit may be added to avoidlong-term damage to the drainage system and to meetlocal code requirements.Vent pipe condensate drains are also required forinstallation of the XFyre. Follow vent manufacturerinstructions for location of condensate drains in thevent. The vent condensate should also be routedthrough a neutralization kit, as required by local coderequirements.The neutralizer kit must be sized to the condensategenerated by the appliance and the vent.WARNING: No substitutions of flue pipe or ventcap material are allowed. Such substitutions wouldjeopardize the safety and health of inhabitants. CAUTION: In general, the condensate piping fromthe appliance must have a downward slope of ¼” perhorizontal foot. Condensate drain traps must beprimed with water to prevent gas flue leaks.Neutralizers should be checked at least once peryear, and the chips should be replenished as neces-sary. When replacing the chips, they should be nosmaller than ¾” to avoid blockage in the condensatepiping. Fig. 27 is a visual guide only. Follow the man-ufacturer’s instructions for the installation of theneutralization kit and condensate drains.Fig. 27: Visual Guide for Condensate Piping33
