Installation & Operation Manual

5Vertical direct venting

Vertical termination – optional concentric vent

￿WARNING

Do not operate the appliance with the rain cap removed or recirculation of combustion products may occur. Water may also collect inside the larger combustion air pipe and flow to the burner enclosure. Failure to follow this warning could result in product damage or improper operation, personal injury, or death.

CAUTION

DO NOT use field-supplied couplings to

extend pipes. Airflow restriction will occur.

 

6.

Install the rain cap and the small diameter pipe assembly

 

into the roof penetration assembly. Ensure the small

 

diameter pipe is cemented and bottomed in the Y

 

concentric fitting.

7.

Cement the appliance combustion air and vent pipes to the

 

concentric vent termination assembly. See FIG. 5-6 for

4.Install the Y concentric fitting pipe assembly through the structure’s hole and field supplied roof boot/flashing.

NOTICE

Do not allow insulation or other materials

to accumulate inside the pipe assembly

 

 

when installing through the hole.

5.Secure the assembly to the roof structure as shown below in FIG. 5-6 using field supplied metal strapping or equivalent support material.

Ensure termination height is above the

roof surface or anticipated snow level (12

 

 

 

inches in U.S.A. or 18 inches in Canada) as

proper pipe attachment.

8. Operate the appliance through one (1) heat cycle to ensure

combustion air and vent pipes are properly connected to

the concentric vent termination connections.

Multiventing vertical terminations

When two (2) or more direct vent appliances are vented near each other, each appliance must be individually vented (see FIG. 5-7). NEVER common vent or breach vent this appliance. When two (2) or more direct vent appliances are vented near each other, two (2) vent terminations may be installed as shown in FIG. 5-7. It is important that vent terminations be made as shown to avoid recirculation of flue gases.
