DV425TR DIRECT VENT ROOM HEATER

INSTALLATION METHODS & NOTES

Four types of direct vent system installations are approved for use with the DV425TR.

1.Horizontal Termination (Fig. 1, page 22)

2.Vertical Termination (Fig. 2, page 23)

3.Into a Class A Metal Chimney (Fig. 3, page 24) USA installations only

4.Into a Masonry Chimney (Fig. 4, page 25) USA installations only

Do not connect to a chimney serving a separate solid- fuel burning appliance.

In each of these installation methods, it is very important to maintain a balance between the combustion air intake and the flue gas exhaust venting system.

Note: Certain limitations as to vent and vertical termination configurations apply, and must be strictly adhered to.

When planning your installation, it is necessary to select the proper length of vent pipe for your particular requirements.

1.For installations with any horizontal vent run or horizontal termination, refer to the Vent Graph on page

27.This graph will show the relationship between vertical and horizontal side wall venting, and help you to determine the amount of vertical rise necessary for “vertical-to-horizontal” type installations. NOTE: Be sure to take into consideration the wall thickness when calculating your venting needs.

2.To determine the length of pipe required for vertical installations, measure the distance from the stove flue outlet to the ceiling, the ceiling thickness, the vertical rise in an attic or second story, and allow for sufficient vent height above the roofline. Refer to the vertical vent termination tables on page 35 for this information. For two-story applications, fire stops are required at each floor level. If an offset is needed in the attic, additional pipe and elbows will be required. When

determining the position of the stove, be sure to adhere to minimum clearance to combustibles to the appliance itself. (See page 8, Minimum Clearances to Combustibles.)

3.When installing this appliance into an existing masonry chimney, it is important to carefully measure the length of flex needed to reach from the appliance outlet to the termination cap. If the flex length is too short, a flex coupler will be needed to attach an additional length of flex liner to make up the difference. If the flex length is too long, the liner could sag below the appliance outlet, which could result in an airflow restriction causing flow reversal or flame lift.

SAFETY PRECAUTIONS FOR THE INSTALLER

Wear gloves and safety glasses for protection when installing this stove. Exercise extreme caution when using ladders or on rooftops around power lines. Be aware of electrical wiring locations in walls and ceilings.
