2. Connect to the structure using mechanically sound means to support the weight. Examples
of typical hardware are illustrated in FIGURE 3 below.
b) If rigid hardware such as 3/8” threaded rod is used for suspension, swing joints or other
means must be provided to allow for system expansion - approximately ½ inch for P40U.
3. P40U Models are packaged with the burner assembled to the tube system at the factory.
For many applications a pre-assembled heater simplifies installation.
4. However, for applications where there is constrained access to the installation location, or if
the tube/reflector system is to be oriented at a 30° mounting angle (see 8. below), we rec-
ommend removal of the burner assembly prior to installation of the tube/reflector assembly.
Simply disconnect the spark wire from the igniter and remove the four bolts that fasten the
burner to the tube flange. Reinstall the burner after the tube system is installed.
5. Survey the available structural supports, considering the system configuration and heat re-
quirements of the area to establish the optimum heater location.
6. Locating a heater directly under joists or beams, and/or installing supplemental steel sup-
port rail or angle iron can substantially reduce labor and material costs.
7. The P40U tube system hangers are located 72 inches (183 cm) apart.
8. The tube/reflector system must be level along its length, but can be oriented on the short
axis either horizontally, or at an angle up to 30 degrees (vent side of tube must be higher
than burner side).
9. When the tube/reflector system is mounted at a 30° angle, the Burner must remain in a
horizontal plane. To simplify installation remove burner from tube system prior to installa-
tion. The mounting flange on the tube allows for horizontal mounting of the burner when
the tube is angled 30° from horizontal.
10. Hardware with a minimum 100 lb. (30 kg) work load must be used at each heater suspen-
sion point. A #2 Lion Chain or equivalent is typically used to suspend the heater.
11. The heater must be supported at all four mounting tabs on the hangers. Also install a chain
from the eye hook at the upper corner of the burner to maintain system orientation.
12. For seismic and high wind restraint see Sections 8-A & 8-B, page 16.

NOTE: It is the installer’s responsibility to ensure that mounting hardware and
fastening to structure are of sufficient strength and integrity to support the system.
