Figure 12. Typical Horizontal Power Direct Vent System.

Vertical Installation

Vertical venting system

must be

supported every 5 feet of vertical run and every 3 feet of horizontal run of vent pipe

length.

CAUTION

Failure to properly support the vent piping with hangers and clamps may result in damage to the water heater or

venting system.

Stress levels in the pipe and fittings can be significantly increased by improper installation. If rigid pipe clamps are used

to hold the pipe in place, or if the pipe cannot move freely through a wall penetration, the pipe may be directly stressed, or

high thermal stresses may be formed when the pipe heats up and expands. Install accordingly to minimize such stresses.

Follow the following procedure for direct venting through the roof:

1. Cut the necessary holes through the roof and ceiling. Cut two 4 ½ inch

(11.4 cm)

diameter holes (for 4 inch (

10.2 cm

) diameter

pipe), or 6 ½ inch (

15.5 cm

) diameter holes (for 6 inch (

15.2 cm

) diameter pipe) in the ceiling and roof.

2. Install the exhaust vent and air intake plastic pipes as shown in Figure 13. Make sure that the installation meets the local codes

and/or The National Fuel Gas Code ANSI Z223.1 (Latest Edition) or CGA/CAN B149 Installation Code.
