Raypak 300, 850 Installation, Termination, Model No, Approved Intakes, Approved Plastic

NOTE: While a drain connection is required in the vent of all XFyre installations, the drain can be ac- complished in several different ways. The figures in this manual show the drain in a vent tee, however, this can also be accomplished using an inline collec- tor for condensing stacks or an inline vertical or horizontal collector available from several of the listed vent manufacturers.

CAUTION: This venting system requires the installation of a condensate drain in the vent piping per the vent manufacturer’s instructions. Failure to install a condensate drain in the venting system will void all warranties on this boiler.

Installation

These installations utilize the heater-mounted blower to draw combustion air and to vent the combustion products to the outdoors. The combustion air intake and the vent are installed horizontally through the wall to the outdoors. Adequate ventilation air must be sup- plied to the equipment room in accordance with the NFGC (U.S.) or B149 (Canada).

The total length of the horizontal through-the-wall direct vent system should not exceed 200 equivalent ft in length. If combined vent/intake run exceeds 200

equivalent ft, an appropriately sized variable-speed extractor must be used. Each elbow used is equal to 10 ft of straight pipe with a maximum of 4 elbows each on the air intake and vent.

The vent and air intake runs should be balanced to provide approximately the same equivalent length. The vent cap and air intake elbow are not considered in the overall length of the venting system.

The vent must be installed to prevent flue gas leakage. Care must be taken during assembly to ensure that all joints are sealed properly and are airtight. The vent must be installed to prevent the potential accumulation of condensate in the vent pipes. It is required that:

1.The vent must be installed with condensate drains as directed by the vent manufacturer.

2.The vent must be installed with a slight upward slope of not less than 1/4 inch per foot of horizon- tal run to the vent terminal.

Termination

The vent cap MUST be mounted on the exterior of the building. The vent cap cannot be installed in a well or below grade. The vent cap must be installed at least 1 ft above ground level and above normal snow levels. Only Raypak-approved vent caps may be used. The vent terminal must be located NO CLOSER than 12” off the wall.

WARNING: No substitutions of flue pipe or vent cap material are allowed. Such substitutions would jeopardize the safety and health of inhabitants.
