American Water Heater AHCG3/HCG360T120 warranty Direct Venting, Direct Vent Terminal Installation

Page 10

IMPORTANT

The vent system must terminate so that proper clearances are maintained as cited in local codes or the current editions of the National Fuel Gas Code, ANSI Z223.1/NFPA 54 or the Natural Gas and Propane Installation Code,

CAN/CSA-B149.1.

Do not terminate the exhaust vent terminal over public area where condensate or vapor can cause nuisance or hazard.

Plan the vent system layout so that proper clearances are maintained from plumbing and wiring.

Vent pipes serving power vented appliances are classified by building codes as "vent connectors". Required clearances from combustible materials must be provided in accordance with information in this manual under LOCATION OF HEATER and CLEARANCES, and with National Fuel Gas Code and local Codes.

IMPORTANT

Plan the layout of the vent system backwards from the vent termination to the appliance.

WARNING

USE ONLY THE VENT TERMINALS SUPPLIED WITH THIS UNIT. TERMINATION OF A VENT SYSTEM WITH A DEVICE OTHER THAN THE SUPPLIED VENT TERMINATIONS WILL AFFECT SYSTEM PERFORMANCE AND RESULT IN A SAFETY HAZARD.

DIRECT VENTING

The air intake provided on the unit contains a mesh screen (see Figure 7) to prevent large particles from entering the unit.

FOR ALL

MODELS

FIGURE 8.

IMPORTANT

WHEN LOCATING THE TERMINALS ON A SIDEWALL, THE FOLLOWING SPECIFICATIONS PERTAINING TO TERMINAL LOCATION MUST BE FOLLOWED.

1.The intake vent terminal and the exhaust vent terminal must terminate on the same exterior wall and must be located at a minimum of 24" (61cm) from the vertical centerline of the exhaust vent terminal (see Figure 9). In colder climates increasing the 24" (61cm) minimum will reduce possibility of frost over from side winds blowing exhaust vapors to the air intake of the direct vent.

2.The horizontal centerline of the intake vent terminal may not be located lower than the horizontal centerline of the exhaust vent terminal (see Figure 9).

FIGURE 7.

WARNING

WHEN THE UNIT IS TO BE SETUP AS A DIRECT VENT, THE MESH SCREEN MUST BE REMOVED. THE INLET VENT PIPE MAY THEN BE GLUED TO THE AIR INTAKE (see Figure 8) PROVIDED ON THE UNIT.

DIRECT VENT TERMINAL INSTALLATION

IMPORTANT

THIS UNIT CONSISTS OF TWO VENT TERMINALS - AN INTAKE VENT TERMINAL AND AN EXHAUST VENT TERMINAL. THE INTAKE VENT TERMINAL IS A 3" 45° PVC ELBOW WITH A DOME MESH WIRE SCREEN AND THE EXHAUST VENT TERMINAL IS A 3" 45°PVC ELBOW WITH A MESH WIRE SCREEN.

NOTE: TO PREVENT EXHAUSTING PRODUCTS FROM CIRCULATING TO THE AIR INTAKE IN WINDY/COLD AREAS, THE MAXIMUM PRACTICAL DISTANCE BETWEEN THESE TWO TERMINALS IS RECOMMENDED

INSTALLATION SEQUENCE

For installations in the City of Los Angeles, California Category IV PVC Pipe such as that manufactured by Brownline Pipe Company, must be used as vent pipe material

CAUTION

Vent terminals supplied with the heater must be used.

NOTE: BEFORE BEGINNING INSTALLATION OF ANY VENT PIPE READ THE VENT PIPE MANUFACTURER'S INSTALLATION INSTRUCTIONS.

1.After the points of termination have been determined, use the cover plates as templates to mark the holes for the vent pipes to be inserted through the wall. BEWARE OF CONCEALED WIRING AND PIPING INSIDE OF WALL.

2.If the vent terminals are being installed on the outside of a finished wall, it may be easier to mark both the inside and outside wall. Align the holes by drilling a hole through the center of the template from the inside through to the outside. The template can now be positioned on the outside wall using the drilled holes as a centering point for the template.

3.A) MASONRY SIDE WALLS

Chisel an opening approximately 1/2" (1.3 cm) larger than the marked circle.

B) WOODEN SIDE WALLS

Drill a pilot hole approximately one quarter inch outside of the marked circle. This pilot hole is used as a starting point for a saws-all or sabre saw blade. Cut around the marked circle staying approximately one quarter inch outside of the line. (This will allow the vent pipe to easily slide through the opening. The resulting gap will be covered by the vent terminal cover plates.) Repeat this step on the inside wall if necessary.

4.Cut a length of 3" PVC pipe about 3.5" (8.9 cm) longer than the wall thickness at the opening.
