Resumen del manual
Vent system termination is permitted in porch areas with two or more sides open. You must follow side wall, overhang and ground clearances as stated in the instructions. Quadra-Fire assumes no responsibility for the improper performance of the appliance when the venting system does not meet these requirements. NOTE 3: Location of the vent termination must not interfere with access CAUTION: IF EXTERIOR WALLS ARE FINISHED WITH VINYL SIDING, Figure 4.4 IT IS SUGGESTED THAT A VINYL PROTECTOR KIT BE INSTALLED.

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 confi guration specifications MUST be followed. • This product is tested and listed to these specifications. • Appliance performance will suffer if specifi cations 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 fi restop 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.

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 top of the appliance to the center of the 90° elbow is 7 ft. (2m), the horizontal run to the outer wall flange must not exceed 9 ft.-8 in. (3m). . Example 2: If the vertical dimension from the top of the appliance is 21 ft. (6m), the horizontal run to the outer wall flange must not exceed 4 ft.-3 in. (1m). 4. Each 90° elbow is equivalent to 3 ft. (914mm) of vent pipe and each 45° elbow is equivalent to 1 ft. (305mm) of vent pipe, and must be subtracted from vent pipe run. A single vertical to horizontal 90° elbow is already calculated into the allowable 15 ft. (5m) run. Each additional 90° elbow reduces the maximum horizontal distance by 3 ft. (914mm). Example: The use of three elbows would reduce the allowable horizontal run to 9 ft. (3 - 1 = 2 elbows x 3 ft. = 6 ft.; 15 ft. max. - 6 ft. = 9 ft. max.) E. Venting Guidelines Notes: • The maximum horizontal vent run is 15 ft. (5m) when the vertical vent rise is 10 ft. (3m). • 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 noncombus...
