Vent Terminal/Indoor Stack Installation

1.Remove the louvered jacket top by removing four

(4) #10 flat head screws.

2.If originally installed, remove "Pagoda" top from the louvered jacket top.

3.Place the inner stack adapter panel over the flue collector inside the heater. Make sure the flanged side of the flue opening is up.

4.Turn the stack (draft hood) up side down and set it down bottom side up.

5.Turn the jacket top panel (removed in Step 1) up side down and place it through the stack.

6.Attach the three (3) mounting brackets to the stack using the screws provided and the holes that are pre-drilled in the stack. Make sure the brackets are positioned with the flange near the top side of the stack (see Fig. 9). Caution must be taken not to over tighten and strip the screw threads.

7.Turn the assembled stack and jacket top, right side up. The jacket top will be trapped between the brackets and the top of the stack. Place the stack over the inner adapter panel flanged hole and lower the louvered jacket top panel back into its original position. Reinstall the four (4) green #10 flat head screws removed in Step 1 above.

WARNING: Indoor heaters require a drafthood that must be connected to a vent pipe and properly vented to the outside. Failure to follow this procedure can cause fire or fatal carbon monoxide poisoning.

Vent piping the same size or larger than the draft hood outlet is recommended, however, when the total vent height is at least ten (10) feet (draft hood relief open- ing to vent terminal), the vent pipe size may be reduced as specified in the National Fuel Gas Code, ANSI Z 223.1. As much as possible avoid long hori- zontal runs of vent pipe and too many elbows.

If installation requires horizontal runs, the vent pipe must have a minimum of 1/4 inch per foot rise and should be supported at not more than five foot inter- vals. Plumbers tape, crisscrossed, will serve to space both horizontal and vertical piping. Maximum vent con- nector horizontal length shall be 1-1/2 feet (18 inches) for each inch of connector diameter as shown in Table F.

Table F: Vent Piping Specifications

Gas vents supported only by the flashing and extend- ing above the roof more than five feet should be securely guyed or braced to withstand snow and wind loads. We recommend use of insulated vent pipe spacer through the roofs and walls.

For protection against rain or blockage by snow, the vent pipe must terminate with a listed vent cap which complies with the local codes or, in the absence of such codes, to the latest edition of the National Fuel Gas Code, ANSI Z223.1.

The discharge opening must be a minimum of two feet vertically from the roof surface and at least two(2) feet higher than any part of the building within ten (10) feet. Vent stack shall be at least five (5) feet in vertical height above the drafthood outlet. The vent cap loca- tion shall have a minimum clearance of four (4) feet horizontally from, and in no case above or below, unless a 4-foot horizontal distance is maintained, from electric meters, gas meters regulators and relief equip- ment.
