Our Answer:

You can indeed connect a section of rigid pipe via an elbow to a length of flexible venting. However, the length of your horizontal run is dependent upon the height of the vertical section. Please visit the venting requirement graph found on page 14 of this item's installation manual. You may download the manual from this item's webpage. A four-foot vertical vent can only support about 5 1/2" of horizontal venting. The 4' flex length will not stretch any longer. It can be trimmed shorter if need be. The 4' flex pipe is the longest flex pipe that we carry for this unit. However, you may select varying lengths of rigid pipe from our collection of DuraVent Direct Vent Pro pipe.

In Response to Question:

I have DVX42FP33CL on order. My plan is to vent vertically out of the fireplace with a DVVK-5F 4 foot flex section to the ceiling firestop, into a 45 elbow, horizontal short section of rigid pipe, into another 45 elbow, short section of rigid pipe, horizontally to a 90 elbow then rigid pipe through the wall into the termination cap. 1. Is a vertical flex into a rigid horizontal OK? 2. Will the 4 ft flex pipe stretch longer? If not, can one section be trimmed if it is too long? 3.Can one purchase longer lengths of flex pipe other than 4"?
