NOTE: While a drain connection is required in the vent of all MVB 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 heater.

Installation

These installations utilize the heater-mounted blower to vent the combustion products to the outdoors. Combustion air is taken from inside the room and the vent is installed horizontally through the wall to the out- doors. Adequate combustion and ventilation air must be supplied to the equipment room in accordance with the NFGC (U.S.) or B149 (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 arrangements:

•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.
