INSTALLATION INSTRUCTIONS FOR

FLEXIBLE VENT KIT PART NUMBER

239-47812-00

This vent kit is designed to bring all air for combustion from the outside and

vent all the combustion products to the outside when properly installed. This

vent kit should only be used with direct vent water heaters that were

designed for use with this vent kit. Refer to the label on the water heater to

determine if this kit is the correct kit for the water heater that you are

installing. Consult the supplier of the water heater if you are not certain that

this is the correct vent kit. Refer to the information in these instructions and

the instructions provided with the water heater when determining the location

of the vent terminal and water heater.

The vent system must terminate so that proper clearances are maintained as

cited in local codes or the latest edition of the National Fuel Gas Code, ANSI

Z223.1 as follows:

1. Do not terminate near soffit vents or crawl space or other area where

condensate or vapor could create a nuisance or hazard or cause

property damage.

2. Do not terminate the exhaust vent terminal where condensate or vapor

could cause damage or could be detrimental to the operation of

regulators, relief valves, or other equipment.

3. Do not terminate the exhaust vent terminal over public area or

walkways where condensate or vapor can cause nuisance or hazard.

4. The vent shall terminate a minimum of 12 inches (30.5 cm) above

expected snowfall level to prevent blockage of vent termination.

Vent pipes serving direct vent appliances are classified by building codes as

“vent connectors”. Required clearances from combustible materials must be

provided in accordance with information in this manual under LOCATION OF

WATER HEATER and CLEARANCES, and with National Fuel Gas Code

and local code.

WARNING

The vent-air intake system must be properly installed. Failure to properly

install the vent-air intake system could result in property damage,

personal injury or death.

DO NOT install any damaged vent-air intake system components.

Contact the manufacturer of the water heater for replacement parts.

VENT-AIR INTAKE SYSTEM INSTALLATION IMPORTANT – Refer to parts list in the back of this manual and become familiar with the parts named in kit. Tools Required For Vent-Air Intake Installation IMPORTANT When the following instructions specify, to seal a vent-air intake joint, use only Loctite Ultra Blue 587 RTV Silicone sealant. A tube of Loctite Ultra Blue 587 RTV Silicone sealant is supplied with every direct vent water heater and each optional vent-air intake kit.

FIGURE 2 1. Measure the vertical height “Y” required in your installation. (See Figure 2). 2. Measure the horizontal length “X” required in your installation (See Figure 2). 3. Add the X & Y dimensions together. If the sum is less than 100 inches (254 cm) and equal to or greater than 44 inches (111.7 cm) the flexible vent can be used with out cutting the flexible vent by stretching or compressing the flexible vent. If the length is less than 44 inches (111.7 cm) the interior 3 inch (7.

4. Cut a 5 7/8 inch (15 cm) diameter minimum clearance hole in the wall at the point where the vent-air intake tubes will pass through the outside wall and connect with the direct vent-air intake terminal (See Figure 2). 5. From outside the building, position the outer wall mount plate and direct vent-air intake terminal over the center of the opening. Mark the mounting screw hole locations. With a 3/16 inch (.5 cm) diameter drill bit (not supplied), drill holes for the wall anchors (supplied).

. Install vent adaptor into the flue reducer. Use the high temperature RTV silicone sealant provided to seal the joint by applying it to the adaptor before inserting the adaptor into the flue reducer. 7. Stretch the inner vent to a length that is 6 inches (15.2 cm) to 12 inches (30.4 cm) shorter than the length needed for the vent installation (X + Y dimension). 8. Place the spacers (springs) around the inner vent so that they are equally spaced. Two of the spacers (springs) must be 4 inches (10.

9. Stretch the outer vent so that it is about 6 inches (15.2 cm) shorter than the inner vent. 10. Slide the outer vent over the inner vent, leaving about 3 inches (7.6 cm) of inner vent exposed on each side. 11. Slide the inner wall backing plate over one end of the outer flexible air intake. Slide the clamps over the ends of both the outer and inner vents.

12. Push the end of the flexible vent with the inner wall backing plate through the hole in the wall. The inner wall backing plate should be on the inside of the wall. The end of the flexible vent and flexible air intake should stick four to six inches outside the wall. 13. Slide the outer vent over the air intake collar on the outer wall mounting plate. Secure the outer vent with the clamp.
