Q&A

Q: I purchased a Hot Dawg HDS 75000 BTU propane heater. What do I need to have to adapt a double-wall pipe to both the exhaust and intake flanges on the heater?

A:

How to attach a single wall vent terminal to double-wall (type B) vent pipe:

  • 1. Look for the “flow” arrow on the vent pipe.
  • 2. Slide the vent terminal inside the exhaust end of the double-wall vent pipe.
  • 3. Drill 3 holes through the pipe and the vent terminal. Using 3/4" long sheet metal screws, attach the cap to the pipe. Do not overtighten.

How to connect a single wall vent system to a double wall (type B) vent pipe:

  • 1. Slide the single wall pipe inside the inner wall of the double-wall pipe.
  • 2. Drill 3 holes through both walls of the single and double wall vent pipes. Using 3/4" sheet metal screws, attach the 2 pieces of pipe. Do not overtighten.
  • 3. The gap between the single and double wall pipe must be sealed but it is not necessary to fill the full volume of the annular area. To seal, run a large bead of 400°F silastic around the gap.

Q: What pipe can I use to get from the concentric kit to the heater? I have an HDS 75000 BTU propane heater. What adapter fits the flanges on the stove?

A: The type of pipe to be used is determined by local code. The connection to the flue on the heater can be made with a coupler or a flue adapter.

Q: What are the dimensions of this?

A: Concentric Box Dims: 19" W x 13-3/8" H x 6" D.

Q: Do you have a more comprehensive kit? Such as one with exhaust and intake pipes, etc?

A: No, I am sorry we do not. It is impossible to have a complete kit since every installation is completely different. There is no one-size-fits-all when it comes to heater installation.
