John S.
from Steubenville,OH asked:
I have a draft hood on my pool heater with a 7-inch female end. I want to order your 7-inch B-vent pipe, which has an outside diameter of 8 inches. What part do I need to make this work?
To connect your pool heater's 7-inch female draft hood to a 7-inch B-vent pipe, you will need a 7-inch B-vent draft hood connector. We offer options from various manufacturers. It's crucial to ensure the brand of the draft hood connector matches the brand of the B-vent pipe you order, as mixing brands for venting components is not recommended due to proprietary connection systems.
Here are two suitable options:
* DuraVent 7 Inch Diameter B-Vent Pipe Draft Hood Connector: Designed to connect B-vent to an appliance's draft hood.
* Metal-Fab Type B Round Chimney Pipe Draft Hood Connector - 7 Inch Inner Diameter: Suitable for connecting to a 7-inch draft hood and intended for use with 7-inch Metal-Fab Type B Round Chimney Pipe.
Please be aware that some field modification, such as crimping, or the use of high-temperature furnace cement/silicone might be necessary for a secure and proper fit.

Gregg
from Warwick, RI asked:
What do I use to mate to existing DVP pipe to a newer Napoleon?
There is nothing you can use to mate the DVP to the newer Napoleon. DVP venting is not to be used with a Napoleon fireplace. It is for select HHT brand fireplaces only.
