CAUTION: IF EXTERIOR WALLS ARE FINISHED WITH VINYL SIDING, IT IS SUGGESTED THAT A VINYL PROTECTOR KIT BE INSTALLED. September 1, 2008 Quadra-Fire · Topaz · 7009-113G Page 9 5 Vent Information A. Venting Components In order to comply with applicable codes and product warranties, use only following venting components: • Hearth & Home Technologies (HHT) • Simpson Dura-Vent • Selkirk Direct-Temp • Amerivent Direct • Security Secure Vent DO NOT USE FIELD-FABRICATED VENTING COMPONENTS. Refer to the venting manufacturer’s instructions. This product is approved to be vented either horizontally, through the side wall or vertically through the roof. You may vent through a Class A or masonry chimney if an approved adapter is used. This appliance is a direct vent heater. All combustion air must B. Use of Elbows CAUTION ALL vent configuration specifications MUST be followed. • This product is tested and listed to these specifications. • Appliance performance will suffer if specifications are not followed. Diagonal runs have both vertical and horizontal vent aspects when calculating the effects. Use the rise for the vertical aspect and the run for the horizontal aspect. (See Figure 5.1.) Two 45° elbows may be used in place of one 90° elbow. On 45° runs, one foot of diagonal is equal to 8-1/2 in. (216mm) horizontal run and 8-1/2 in. (216mm) vertical run. A length of straight pipe is allowed between two elbows. (See Figure 5.1.) come directly from the outside of the building. The vent pipe for this unit consists of an inner and an outer pipe. The inner pipe carries the appliance exhaust out of the system, and the outer pipe brings fresh combustion air into the appliance. • A round support box/wall thimble or heat shield is required when the venting passes through a combustible wall. • A support box or ceiling firestop is required when the venting passes through a ceiling. • Roof flashing and a storm collar are required when venting passes through the roof. • Follow instructions provided with the venting for installation of these items. Vertical Horizontal 12 in.8-1/2 in. 8-1/2 in. Figure 5.1 Fire Hazard. Explosion Risk. Asphyxiation Risk. Do NOT connect this gas appliance to a chimney flue serving a separate solid-fuel or gas burning appliance. • Vent this appliance directly outside. • Use separate vent system for this appliance. May impair safe operation of this appliance or other appliances connected to the flue. WARNING Vertical and horizontal measurements were made using the following standards. C. Measuring Standards • Pipe measurements are from center line to center line. • Horizontal terminations are measured to the outside of the mounting surface (flange of termination cap). See Figure 4.1 on page 8. • Vertical terminations are measured to the top of the last pipe before termination cap. • Horizontal pipe installed level with 1/4 in. rise. Page 10 Quadra-Fire · Topaz · 7009-113G September 1, 2008 D. How to Use the Vent Graph 1. Measure the vertical distance from the center line of the flue pipe to the center of the 90° elbow. On the graph below, draw a horizontal line from that measurement on the vertical axis across until it intersects with the slanted line. 2. From the point of this intersection, draw a vertical line to the bottom of the graph. 3. The point at which this line meets the bottom line of the graph is the maximum length of the horizontal run. EXAMPLE 1: If the vertical dimension from the center line of the flue vent to the center of the 90° elbow is 7 ft. (2m), the horizontal run to the outer wall flange must not exceed 16 ft. (5m). EXAMPLE 2: If the vertical dimension from the center line of the flue vent is 21ft. (6m), the horizontal run to the outer wall flange must not exceed 12 ft. 10 in. (4m). 4. Each 90° elbow is equivalent to 3 ft. (914mm) of vent pipe and each 45° elbow is equivalent to 1ft. (305mm) of vent pipe, and must be subtracted from the vent pipe run. A single horizontal to vertical 90° elbow is already calculated into the allowable 20 ft. (6m) run. Each additional 90° elbow reduces the maximum horizontal distance by 3 ft. (914mm). EXAMPLE: The use of 3 elbows would reduce the allowable horizontal run to 9 ft. (3 -1 = 2 elbows x 3 ft. = 6 ft.; 20 ft. max. - 6 ft. = 14 ft. max.). E. Venting Guidelines NOTES The maximum horizontal vent run is 20 ft. (6m) when the vertical vent rise is 10 ft. (3m). The minimum horizontal vent run is 6 in. (152mm) Horizontal sections require a 1/4 in. (6mm) rise for every 12 in. (305mm) of horizontal travel. Exterior Vent Diameter = 6-5/8 in. (168mm); Inner Vent Diameter = 4 in. (102mm). Horizontal sections require noncombustible support every 3 ft. (914mm), e.g. wall straps. For any vertical termination a minimum of 6 ft. (2m) vertical must be used. EXCEPTIONS FOR HORIZONTAL INSTALLATIONS: *When installing the Topaz in a rear vent configuration with no vertical rise, a Snorkel Kit must be used. *The maximum horizontal vent run is 3 ft. (914mm). *The maxi...
