3. Exhaust Flue System Installation
The exhaust system is critical for the safe operation of the heater, as it exhausts the products
of combustion out of the building to the ambient environment. Because the exhaust gas is
much hotter than the outside air, it will naturally rise through the flue and create a negative
pressure behind it. This is commonly referred to as “draft”.
3.1 Barometric Damper Tee Installation
The barometric damper tee helps to regulate draft
pressure through varying ambient conditions.
Install the tee with the tapered end pointing
downward by sliding it into the heat exchanger
outlet until snug (refer to figure). Secure using 3
sheet metal screws. Do NOT
operate the heater without a Tee and Damper for
draft control.
3.2 Flue Piping Installation
The flue piping exhausts products of combustion
out of the building into the ambient environment.
Insert Tee with
taper end down.
Damper Tee Installation
You may have a basic knowledge of carpentry and the use of hand tools.
However, it is important that you review all safety rules in this section, and all safety rules in
the manuals provided with your manufactured flue kit. If you have any doubt about your
ability to complete the installation in a safe and workmanlike manner, you should arrange for
a professional installation. For more regulatory information regarding flue pipe installation,
consult NFPA 31 and your local fire protection and building codes.
Flue System Installation Steps and Considerations:
• Review this section completely. Choose and purchase a factory-built flue kit
that complies with U.L. standard 103 Type HT, or Equivalent.
•
The XT 75 requires a 6-inch diameter flue and may not be reduced.
•
For your convenience, the unit includes some helpful chimney-flue material.
Additional material will also be necessary.
• Read and follow the product and safety instructions in the Appendix of
this manual or those that were included with your selected flue kit. If product
instructions were not included, contact the manufacturer of your kit to obtain the
instructions. Additional support material are available at
www.lanair.com . If you are
unsure of your ability to properly install the flue system, hire a professional installer or
contact Technical Support for assistance.
