NRTL Listed (Class A) Chimney
Carefully follow the chimney manufacturers instructions. Use only listed type HT per UL 103, 6"
inch diameter black or blued chimney connector with a minimum thickness of no less than 24 gauge. If
your chimney starts at the ceiling you will need enough 6" inch pipe to reach the ceiling. The top of the
chimney must be at least 3' feet above the roof and be at least 2' feet higher than any point of the roof
within 10' feet.
Rules For Connector Pipe Installation
1. Crimped end of the pipe must always be installed towards the heater. The pipe should slide into
the flue collar. The pipe should fit firmly inside and be mechanically attached to the flue collar,
locked with at least three (3) screws and sealed with furnace cement
2. If you have a pipe running horizontally, the horizontal length can not exceed 12' feet regardless
of the height of the chimney. If the chimney is 24' feet or less in height, the height of the
chimney must be at least twice the length of the horizontal run.
3. You must have at least 18" inches of clearance between any horizontal piping and the ceiling.
4. Secure any connector pipe joint with at least three (3) sheet metal screws and seal with furnace
cement, including the joint(s) at the chimney.
5. It is recommended that not more than four (4) bends of 90 degrees OR any amount of bends
regardless of direction exceeding a total of 360 degrees be used in the pipe installation as more
than that can cause a decrease in draw and may cause back draft or smoke spillage.
6. The chimney connector shall not pass through an attic, roof space, floor, wall ceiling, or any
other similar concealed space. Where passage through a wall or partition of combustible is
desired, the installation must conform with NFPA 211.
*It is highly recommend that an insulated double wall pipe is used instead of a triple wall pipe.
Though a triple wall pipe can and has been used successfully, in situations where the pipe is exposed
outside the structure for long rises (such as a through wall installation) triple wall pipe does not have
nearly as effective of a draft as insulated double wall pipe. Triple wall pipe does not insulate the
chimney, instead it works via convection of cold air to cool the pipe. Due to the Rocket Heaters low
exhaust gas temperatures the cooling effect of triple wall pipes design prevents proper draft from being
established in some installations.
