PHYSICAL LAYOUT - GENERAL NOTE: Do not use these parts to combine the commercial condensing gas water heaters with any other heater or gas appliance. The system layout must be planned to minimize the linear length and number of fittings in the system. Consult the water heater’s installation instructions in the I&O Manual for proper clearances for service which can be found under Section IV: INSTALLATION INSTRUCTIONS for Group 1 and 2. -

Vent Gas Direction Combustion Air Direction FIGURE 2. SANITARY TEE as an acceptable substitute, provided they are arranged so that the flows are in the directions indicated in Figure 2. VENTING SUPPORTS DO NOT SUPPORT WEIGHT OF VENT SYSTEM ON THE HEATER. Supports must be installed every 3 feet of horizontal run and 5 feet of vertical run for both the intake and exhaust venting. - Page 9 FIGURE 4. Recommended Horizontal Direct Vent System Installation. (Intake and Exhaust Terminals may be on different outside walls.) The air intake terminal is a 90° elbow pointing down and the exhaust terminal is the end of a straight pipe section when venting through a wall, see Figure 4.
