Flue Assembly Installation
1. Locate the flue assembly and the extension (refer to
Figure 25, p. 45 for extension usage) in the ship
with section of the unit.
2. Install the flue extension onto the flue assembly as
shown in Figure 25, p. 45 .
3. Slide the pipe clamp onto the heater flue tube
located inside the heater compartment.
4. Insert the tube on the flue assembly into the hole
located in the vertical support for the heat section.
5. Butt both tube sections together and center the pipe
clamp over joint.
6. Using the pre-punch holes in the flue assembly,
extension, and the vertical support, install the
appropriate number of mounting brackets (Refer to
the installation instructions that ship with the flue
assembly.)

General Coil Piping and
Connection Recommendations
Proper installation, piping, and trapping is necessary to
ensure satisfactory coil operation and to prevent
operational damage:
N No otte e:: The contractor is responsible for supplying the
installation hardware.
☐ Support all piping independently of the coils.
☐
Provide swing joints or flexible fittings on all
connections that are adjacent to heating coils to
absorb thermal expansion and contraction strains.
☐ Install factory supplied control valves (valves ship
separately).

☐ When attaching the piping to the coil header, make
the connection only tight enough to prevent leaks.
Maximum recommended torque is 200 foot-
pounds.
