SECTION C: Installation

Fig. 24: Horizontal Through-the-Wall Direct Venting

CAUTION: This venting system requires the installa- tion 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 heater.

Installation

These installations utilize the heater-mounted blower to vent the combustion products to the outdoors. Com- bustion air is taken from inside the room and the vent is

installed horizontally through the wall to the outdoors. Adequate combustion and ventilation air must be sup- plied to the equipment room in accordance with the NFGC (U.S.) or B149.1 (Canada).

The total length of the horizontal through-the-wall flue system should not exceed 75 equivalent ft in length. If horizontal run exceeds 75 equivalent ft, an appropri- ately sized variable-speed extractor must be used. Each elbow used is equal to 10 ft of straight pipe. This will allow installation in one of the four following arrange- ments:

•75’ of straight flue pipe

•65’ of straight flue pipe and one elbow

•55’ of straight flue pipe and two elbows

•45’ of straight pipe and three elbows

The vent cap is 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 a condensate drain located in proximity to the heater 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.
