See heater dimensions and assembly overview (Sections 7 ) for each Linear model configurations.
During field assembly of the heater body sections, the recommended procedure is as follows:
1.
Determine the actual layout of the system first before hanging heater sections. Consideration must also be
taken for flue pipe, fresh air ducting, gas piping, clearances to combustibles, etc. before hanging heater.
2. Install the heater suspensions using chains or other type methods outlined in Section 8 “Typical Sus pension
M ethods”. Space these per the assembly overview for each heater.
3. Space two (2) tube support/hanger brackets at distances indicated in each assembly overview for the first
tube section. Note: The distances are measured from center of the slotted holes of each support/hanger
bracket.
4. Place tubes over these brackets with the welded seam facing down toward the ground. Failure to assemble
the tube with the seam facing down will void the
manufacturer’s warranty. Secure the tubes to each
support/hanger bracket using U-bolt clamps and 5/16-18 nuts provided.
5. Raise the tube section up to the suspension chain (or other methods), using “S” hooks to attach the t ube
support brackets. Hang each tube section individually. DO NOT assemble all of the heater tube sections
together on the ground and attempt to hang the entire system. Provide a slope of 0.25 degree up to the fan
on linear tube heaters.
6. Continue to pre-assemble and hang each additional section as before. Join each section together using
Torctite couplings as described in Section 9.1
“Tube Coupling Details” .
7. Insert turbulators (where required) into the tube sections as shown in Section 9.2 “Inserting Turbulators” .
8. Attach burner box and fan assembly as shown in Sections 9.3 and 9.4 respectively.
9. Place main body reflector panels over each of the tube support/hanger brackets installed above.
10. Slide reflector panels and space between burner box and U-bend (U-model heaters only) as indicated on
heater dimension drawings. Reflectors must overlap approximately as shown on the dimension drawings.
11. Secure reflectors to tube support/hanger brackets using the screws and clamps (supplied in fastening kits).
Note: Refer to details A or B of each assembly overview drawing for the required open or closed positions of
the clamps. These positions enable reflectors to side or remain stationary during operation of heater.
12. Place end reflector panels flush to each end of main heater reflector panels and secure by spacing two (2) U-
type speed clips (supplied in fastening kits) evenly on edges of each reflector flange.
13. Make all final gas and electric connections as outlined later in the instructions.
14. Affix user instruction label adjacent to controls. See section 8.3.
Failure to assemble the tube with the seam facing down will void the
manufacturer’s warranty.
