Notes:
1. Installer may choose to use five-inch where four-inch pipe is shown
2. Runs should be reduced as follows for listed accessories. Each 90° elbow-10 feet. Each 45° elbow-5 feet. Briedert cap or equivalent-10 feet.
3. Discharge of the flue vent fan is five inches. Therefore, a transition by the installer is required on 30 through 175 MBh and 400 MBh units.
On units 30-250 MBh, flue vent fan and adapter ship in the same box. On units over 250 MBh, flue vent fan and adapter ship in separate boxes.
