To install a chimney pipe in a multi-story house, use connector (stove) pipe only in the room and transition to a UL 103HT listed Class A insulated chimney at the ceiling support box. The Class A chimney then passes through each floor, attic, and roof with 2-inch clearance to combustibles at every level.

To install a chimney through the attic, connect a stove pipe from your wood stove to a ceiling support box, then transition to UL 103HT listed Class A insulated chimney pipe that runs through the attic and exits the roof. Choose the correct support box length (11", 24", or 36") based on your total ceiling thickness.

You install a chimney through a cathedral ceiling by running stove pipe from the appliance up to a ceiling support box, then switching to Class A insulated chimney pipe (UL 103 HT) for everything that passes through the roof. Because there is no attic, the support box mounts directly to the ceiling framing, and the chimney exits straight through the roof above.

The best stove pipe for a wood-burning stove is a single-wall or double-wall black steel connector that matches your stove's flue collar diameter - typically 6 or 8 inches. Single-wall pipe radiates more heat into the room, while double-wall keeps flue gases hotter for stronger draft. Both types are for indoor use only.

Every Class A chimney installed inside a house needs a ceiling support box where the stove pipe connects to the insulated chimney pipe. Additional components - attic insulation shields, floor/ceiling radiation shields, and roof support brackets - depend on your ceiling type and how many floors the chimney passes through. This guide covers all five installation scenarios so you pick the right parts the first time.

Measure the horizontal distance between the centers of your two elbow positions, then use an offset chart to find the rise and connector pipe length. For Class A chimney pipe (UL 103 HT listed), you can choose between 15-degree and 30-degree elbow kits. Per NFPA 211, the connector between elbows must not exceed 72 inches, and you are limited to two offsets (four elbows) per chimney system.

Yes, you should box in a chimney pipe on the upper floor. U.S. building codes (NFPA 211 and the IRC) require Class A chimney pipe to be enclosed in a fire-rated shaft or chase wherever it passes through a finished living space. This enclosure maintains the required 2-inch clearance to combustibles and creates a vertical fire barrier between floors.

Texas follows the International Residential Code (IRC), which references NFPA 211 for chimney and venting systems. Most cities require a building permit and post-installation inspection for any wood stove or chimney pipe installation. No statewide license is required for DIY chimney work, but your installation must meet IRC clearance, height, and material requirements to pass inspection and keep your homeowner's insurance valid.

Yes, a listed wood stove can be installed in a manufactured home when the exact appliance is approved for that use and the installation follows its listing, federal requirements and applicable local rules.
