5.3.5 Louvers and Grilles:

In calculating free area in 5.3.3, consideration shall be given to the blocking effect of louvers, grilles or screens protecting openings. Screens used shall not be smaller than 1/4 inch mesh. If the area through a design of louver or grille is known, it should be used in calculating the size of opening required to provide the free area specified. If the design and free area is not known, it may be assumed that wood louvers will have 20- 25 percent free area and metal louvers and grilles will have 60-75 percent free area. Louvers and grilles shall be fixed in the open position or interlocked with the equipment so that they are opened automatically during equipment operation.

5.3.6Special Conditions Created by Mechanical Exhausting or Fireplaces:

Operation of exhaust fans, ventilation systems, clothes dryers, or fireplaces may create conditions requiring special attention to avoid unsatisfactory operation of installed gas utilization equipment.

VI. CATEGORY I VENTING (VERTICAL VENTING)

WARNING

TO PREVENT POSSIBLE PERSONAL INJURY OR DEATH DUE TO ASPHYXIATION, THIS FURNACE MUST BE CATEGORY I VENTED. DO NOT VENT USING CATEGORY III VENTING.

Category I Venting is venting at a non-positive pressure. A furnace vented as Category I is considered a fan-assisted appliance and the vent system does not have to be “gas tight.” NOTE: Gas furnaces with induced draft blowers draw products of combustion through a heat exchanger allowing, in some instances, common venting with natural draft appliances (i.e. water heaters).

All installations must be vented in accordance with National Fuel Gas Code NFPA 54/ANSI Z223.1 - latest edition. In Canada, the furnaces must be vented in accordance with the National Standard of Canada, CAN/CSA B149.1 and CAN/CSA B149.2 - latest editions and amendments.

NOTE: The vertical height of the Category I venting system must be at least as great as the horizontal length of the venting system.

WARNING

TO PREVENT POSSIBLE PERSONAL INJURY OR DEATH DUE TO ASPHYXIATION, COMMON VENTING WITH OTHER MANUFACTURER'S INDUCED DRAFT APPLIANCS IS NOT ALLOWED.

The minimum vent diameter for the Category I venting system is as shown below:

Upflow or Horizontal units are shipped with the induced draft blower discharging from the top of the furnace. (“Top” is as viewed for an upflow installation.) The induced draft blower can be rotated 90 degrees for Category I venting (Figure 3). For horizontal installations, a four inch single wall pipe can be used to extend the induced draft blower outlet 1/2” beyond the furnace cabinet. Vent the furnace in accordance with the National Fuel Gas Code NFPA 54/ANSI Z223.1 - latest edition. In Canada, vent the furnace in accordance with the National Standard of Canada, CAN/CSA B149.1 and CAN/CSA B149.2 - latest editions and amendments.

Upflow Rotated Induced Draft Blower

To rotate the induced draft blwer counterclockwise, proceed as follows:

1.Disconnect electrical power from the furnace.

2.Disconnect the induced draft blower power leads, flue pipe, and pressure switch tubing.

3.Remove the round cutout from the appropriate side of the furnace.

4.Remove and save the four screws that hold the induced draft blower to the flue collector box.

5.Turn the induced draft blower 90 degrees clockwise, or counterclockwise. The gasket is adhered to the back plate and will rotate with the blower assembly.

6.Reinstall the induced draft blower on the flue collector box, using the four screws removed in Step 3. Tighten screws to provide an airtight seal.

7.Reconnect the induced draft blower power leads. NOTE: If the wires are not long enough, pull extra wire from the wire bundle in the blower compartment.

8.Remove and save the screw that holds the pressure switch to the furnace top panel.

9.Relocate the pressure switch to the same side as the flue outlet in the hole provided.

10.Reconnect the draft blower power leads, flue pipe, and pressure switch tubing. Make sure that all wires and the pressure switch tubing are at least one inch from the flue pipe, or any other hot surfaces.

11.Restore power to the furnace.

Under some conditions, larger vents than those shown above may be required or allowed.

When an existing furnace is removed from a venting system serving other appliances, the venting system may be too large to properly vent the remaining attached appliances.

WARNING

NEVER ALLOW THE PRODUCTS OF COMBUSTION, INCLUDING CARBON MONOXIDE, TO ENTER THE RETURN DUCTWORK OR CIRCULATION AIR SUPPLY.
