Vermont Casting DVRT41 Twist Lock Pipes, How to Use the Vent Graph, Rear Wall Vent Application

Twist Lock Pipes

When using twist lock pipe it is not necessary to use sealant on the joints. The only areas of the venting system that need to be sealed with high temperature silicone sealant are the collars on the fireplace and termination, and the sliding joint of any telescopic vent section used in the system.

To join twist lock pipes together, simply align the beads of the male end with the grooves of the female end, twisting the pipe until the flange on the female end contacts external flange on the male end. It is recom- mended that you secure the joints with three (3) sheet metal screws, however, this is not mandatory with twist lock pipe. (Fig. 17)

To make it easier to assembly the joints, we suggest putting a lubricant (Vaseline or similar) on the male end of the twist lock pipe prior to assembly.

How to Use the Vent Graph

The Vent Graph should be read in conjunction with the following vent installation instructions to determine the relationship between the vertical and horizontal dimen- sions fo the vent system.

1.Determine the height of the center of the horizontal vent pipe exiting through the outer wall. Using this dimension on the Sidewall Vent Graph (Fig. 17), locate the point intersecting with the slanted graph line.

2.From the point of this intersection, draw a vertical line to the bottom of the graph.

3.Select the indicated dimension, and position the fireplace in accordance with same.

EXAMPLE A:

If the vertical dimension from the floor of the unit is 11’ (3.4m) the horizontal run to the face of the outer wall must not exceed 14’ (4.3m).

EXAMPLE B:

If the vertical dimension from the floor of the unit is 7’ (2.1m), the horizontal run to the face of the outer wall must not exceed 8¹⁄₂’ (2.6m).

Rear Wall Vent Application

When installed as a rear vent unit this appliance may be vented directly to a termination located on the rear wall behind the appliance.

Only CFM Corporation venting components are approved to be used in these applications (See ‘Venting Components’ listed for different installation requirements).

The maximum horizontal distance between the rear of the appliance (or end of the transition elbow in a corner application) and the outside face of the rear wall is 20” (508mm). (Fig. 19, 20)

Only one 45° elbow is allowed in these installations.

Minimum clearances between vent pipe and com- bustible materials are as follows:

Top - 2" (51 mm)

Sides - 1" (25 mm)

Bottom - 1" (25 mm)
