For 4" Venting, the maximum equivalent feet of pipe allowed is 160 feet (48.8 m). This does not include the Vent Termination (supplied locally) for the water heater. For the 4" venting, one 90° elbow is approximately equal to 8 feet (2.4 m). One 45° elbow is approximately equal to 4 feet (1.2 m). It is recommended that at least 2 feet (0.6 m) of spacing be used in between all 45° elbows and all 90°elbows.

55,000 and 62,500 BTU Units:

NOTE: The 55,000 and 62,500 BTU Units are not approved for 2" venting.

For 3" Venting, the maximum equivalent feet of pipe allowed is 80 feet (24.4 m). This does not include the supplied Vent Termination for the water heater. For the 3" venting, one 90° elbow is approximately equal to 5 feet (1.5 m). One 45° elbow is approximately equal to 2.5 feet (0.8 m). It is recommended that at least 2 feet (0.6 m) of spacing be used in between all 45° elbows and all 90°elbows.

For 4" Venting, the maximum equivalent feet of pipe allowed is 120 feet (36.6 m). This does not include the Vent Termination (supplied locally) for the water heater. For the 4" venting, one 90° elbow is approximately equal to 8 feet (2.4 m). One 45° elbow is approximately equal to 4 feet (1.2 m). It is recommended that at least 2 feet (0.6 m) of spacing be used in between all 45° elbows and all 90°elbows.

VENTING

The vent system must terminate so that proper clearances are maintained as cited in local codes or the current edition of the National Fuel Gas Code, ANSI Z223.1/NFPA 54, 7.3.4e and 7.8a,b, as follows:

1.The exit terminals of a mechanical vent system shall be not less than 7 feet (2.13 m) above grade when located adjacent to public walkways, see Figure 16.

2.A venting system shall terminate at least 3 feet (0.91 m) above any forced air inlet located within 10 feet (3.1 m), see Figure 16.

3.The venting system shall terminate at least 4 feet (1.2 m) below, 4 feet (1.2 m) horizontally from or, 1 foot (0.31 m) above any door, window or gravity air inlet into any building.

The manufacturer also recommends that the vent termination should not be installed closer than 18" (45.7 cm) from an inside corner of an L shaped structure and not be less than 1 foot (0.31 m) above grade.

The vent shall terminate a minimum of 12'' (30.5 cm) above expected snowfall level to prevent blockage of vent termination, see Figure 16.

4.In cold climates, it is recommended that vent termination not be mounted directly above or within 3 feet (0.91 m) horizontally from an oil tank vent or gas meter to avoid potential freeze-up from condensation, see Figure 16..

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 VENT TERMINAL INSTALLATIONS, and with the National Fuel Gas Code and local codes.

VENT TERMINAL INSTALLATION

1.After the point of termination has been determined, use the cover plate as a template to mark the hole for the vent pipe to insert through the wall. BEWARE OF CONCEALED WIRING AND PIPING INSIDE OF WALL.

2.If the Vent Terminal is 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 hole as a centering point for the template.

3.A) MASONRY SIDE WALLS

Chisel an opening approximately one half inch 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 up by the vent terminal cover plates.) Repeat this step on inside wall if necessary.
