For California Residents:

If installed with a manufactured (mobile) home conversion kit in

SCAQMD: This furnace does not meet the SCAQMD Rule 1111 14 ng/J

NOx emission limit, and thus is subject to a mitigation fee of up to $450.

This furnace is not eligible for the Clean Air Furnace Rebate Program:

www.CleanAirFurnaceRebate.com

MINIMUM CLEARANCES TO COMBUSTIBLE

MATERIALS

The furnace should be sized to provide 100 percent of the design heating

load requirement plus any margin that occurs because of furnace model

size capacity increments. None of the furnace model sizes can be used if

the heating load is 20,000 BTU or lower. Use Air Conditioning

Contractors of America (Manual J and S); American Society of Heating,

Refrigerating, and Air-Conditioning Engineers; or other approved

engineering method to calculate heating load estimates and select the

furnace. Excessive oversizing of the furnace may cause the furnace

and/or vent to fail prematurely, customer discomfort and/or vent

freezing.

Failure to follow these guidelines is considered faulty installation and/or

misapplication of the furnace; and resulting failure, damage, or repairs

may impact warranty coverage.

Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.

NOTE:

1. A filter is required for each return-air inlet. Airflow performance included 3/4-in. (19 mm) washable filter media such as contained in a factory - authorized accessory filter rack. See

accessory list. To determine airflow performance without this filter, assume an additional 0.1 in. w.c. available external static pressure.

2. Adjust the blower airflow settings as necessary for the proper air temperature rise for each installation.

3. Airflows over 1800 CFM require bottom return, two-side return, or bottom and side return. A minimum filter size of 20” x 25” (508 x 635 mm) is required.

4. For upflow applications, air entering from one side into both the side of the furnace and a return air base counts as a side and bottom return

5. The -- entry indicates unstable operating conditions

Deductions from Maximum Equivalent Vent Length - Ft. (M)

NOTE:

1. Use only the smallest diameter pipe possible for venting. Over-sizing may cause flame disturbance or excessive vent terminal icing or freeze-up.

2. NA - Not allowed. Pressure switch will not close, or flame disturbance may result.

3. Vent sizing for Canadian installations over 4500 ft (1370 M) above sea level are subject to acceptance by local authorities having jurisdiction.

4. Size both the combustion air and vent pipe independently, then use the larger size for both pipes.

5. Assume the two 45_ elbows equal one 90_ elbow. Wide radius elbows are desirable and may be required in some cases.

6. Elbow and pipe sections within the furnace casing and at the vent termination should not be included in vent length or elbow count.

7. The minimum pipe length is 5 ft. (2 M) linear feet (meters) for all applications.

8. Use 3-in. (76 mm) diameter vent termination kit for installations requiring 4-in. (102 mm) diameter pipe

Venting System Length Calculations

The Total Equivalent Vent Length (TEVL) for EACH combustion air or vent pipe equals the length of the venting system, plus the equivalent length of

elbows used in the venting system from Deductions from Maximum Equivalent Vent Length - Ft. (M) Table.

Standard vent terminations or factory accessory concentric vent terminations count for zero deduction.

See vent system manufacturer’s data for equivalent lengths of flexible vent pipe or other termination systems. DO NOT ASSUME that one foot of

flexible vent pipe equals one foot of straight PVC/ABS DWV vent pipe.

Compare the Total Equivalent Vent Length to the Maximum Equivalent Vent Lengths in Maximum Equivalent Vent Length Table.

Example 1

A direct-vent 60,000 BTUH furnace installed at 2100 ft. (640M). Venting system includes FOR EACH PIPE:

70 feet (22 M) of vent pipe, 65 feet (20 M) of combustion air inlet pipe, (3) 90º long-radius elbows, (2) 45º long-radius elbows, and a factory accessory

concentric vent kit.

Can this application use 2” (50 mm ND) PVC/ABS DWV vent piping?

Example 2

A direct-vent 60,000 BTUH furnace installed at 2100 ft. (640M). Venting system includes FOR EACH PIPE:

100 feet (30 M) of vent pipe, 95 feet (29 M) of combustion air inlet pipe, (3) 90º long-radius elbows, and a polypropylene concentric vent kit. Also

includes 20 feet (6.1 M) of flexible polypropylene vent pipe, included within the 100 feet (30 M) of vent pipe.

VERIFY FROM POLYPROPYLENE VENT MANUFACTURER’S INSTRUCTIONS for the multiplier correction for flexible vent pipe.

Can this application use 60mm o.d. (2”) polypropylene vent piping? If not, what size piping can be used?
