76,000 BTU (283.9 L - 22.3 kW/Hr) models. Part II will cover venting specifications for 40 Gal - 40,000 BTU (151.4 L - 11.7 kW/ Hr) and 48 gal - 40,000 BTU (181.7 L - 11.7 kW/Hr) models. Refer to the rating plate located on the water heater for correct model identification.

The National Fuel Gas Code ANSI Z223.1-(Latest Edition), CGA/CAN B149 Installation Code, and local codes have specific requirements for the location of the vent terminals on vertical walls. The guide lines listed below are from the National Fuel Gas Code. Consult the local codes, and/or National Fuel Gas Code ANSI Z223.1-(Latest Edition), or CGA/CAN B149 Installation Code to determine if there are any additions or changes to the following specifications.

(A)The vent terminal must terminate at least 3 feet (.91 m) above any forced air inlet duct located within 10 feet (3 m). Exception: This provision shall not apply to the combustion air intake of a direct vent appliance.

(B)The vent terminal must terminate at least 4 feet (1.2m) below, 4 feet (1.2 m) horizontally from, or 1 foot (0.31 m) above any door, window, gravity air inlet into the building.

(C)The bottom of the vent terminal must be located at least 1 foot (0.31 m) above ground and above the anticipated snow level.

(D)The vent terminal must not terminate over a public walkway or over an area where condensate or vapor could create a nuisance or hazard or could be detrimental to the operation of regulators, relief valve, or other equipment.

(E)The water heater location must provide easy access for the entire length of the vent connector.

(F)The vent system must be inspected at least once a year to ensure against leakage of exhaust products.

Exceptions For Installations in Canada:

(A)The vent terminal must be located at least 1 foot (0.31 m) from any window or door which can be opened in any building, any non-mechanical air supply inlet to any building, or the combustion air to any inlet other appliance.

(B)The vent terminal must be located at least 6 feet (1.8 m) from any mechanical air supply inlet to the building.

(C)The vent terminal must not terminate above a meter/regulator assembly within 3 feet (0.91 m) horizontally of the vertical center line of the regulator and must be at least 6 feet (1.8 m) from any gas service regulator vent outlet.

(D)The vent terminal must be at least 7 feet (2.1 m) above a paved sidewalk or a paved driveway located on public property.

(E)The vent terminal must not terminate above a paved sidewalk or a paved driveway, which is located on private adjacent property.

VENTING SYSTEM CONDENSATION

Condensate formation does not occur in all installations of power vented heaters, but should be protected against on installations where condensation can form in the venting system.

Formation of condensation in the venting system of Power Vented water heaters is dependent upon installation conditions including, but not limited to:

1.Ambient temperature and humidity of installation location;

2.Ambient temperature and humidity of venting space; vent distance and slope;

3.And product usage.

RPV-I&S

In order to effectively control condensate from adversely affecting the mechanical components of the water heater several methods may be employed:

1.For horizontal installations the vent pipe can be installed with a downward slope (not less than 1/8" nor greater than 1/2” per foot maximum) and away from the blower motor.

2.In order to prevent condensate from draining back into the blower (vertical or horizontal runs), a fitting and drain hose is available as a condensate trap kit (see Table 1 for service part numbers). The all rubber fitting with drain outlet mounts directly to the blower motor outlet and is secured with two hose clamps (one to the blower motor outlet and the other to the vent connector). The plastic tubing is provided to drain any accumulated condensate away from the water heater and to a suitable drain. The kit comes complete with instructions for proper installation of the fitting.

3.In order to prevent condensate from draining back into the blower (vertical or horizontal runs), a drain tee and condensate trap can be installed in the horizontal vent as close as practical to the blower vent connection (see Figure1). The condensate disposal tube should be installed to drain any accumulated condensate away from the water heater and to a suitable drain. The drain tee and condensate hose should be available through your local distributor.

Part I - Venting Specifications for:

48 Gallon, 65,000 BTU input (181.7 L, 19.1 kW/Hr)

65 Gallon, 65,000 BTU input (246.1 L, 19.1 kW/Hr)

75 Gallon, 76,000 BTU input (283.9 L, 22.3 kW/Hr)

This water heater is a power vented appliance and is designed to vent its products of combustion through 3" (7.6 cm) or 4" (10.2 cm) diameter Schedule 40 (solid or cellular core) PVC pipe to the outdoors. This water heater may be either vented through the wall or vertically through the roof. Use a 3" (7.6 cm) to 4" (10.2 cm) reducer to connect to the vent outlet when using 4" (10.2 cm) PVC. Table 2 lists the maximum vent lengths for this water heater using 3" (7.6 cm) PVC. If possible, locate the water heater so that the venting length and number of elbows are kept to the minimum distance necessary to reach the outside. If the installation requires venting lengths that exceed the lengths listed for 3" (7.6 cm) PVC in Table 2, then use 4" (10.2 cm) PVC for the vent connector. Table 3 lists the venting distances allowed with 4" (10.2 cm)
