COMMISSIONING
1 - Installation Checklist
Before proceeding with the start-up of the system, review the list of items below to ensure proper operation.
Close all Quick links and turnbuckles to avoid unlocking chain with inadvertent contact.
Verify that the Burners are correct for the fuel being burned. The rating plate listing this information is located on
the Burner housing, check this against your site plans.
Burners are position dependent. For proper operation, ensure that the Burner labeled as ‘No. 1’ on the housing is
located at the end of each Radiant Branch. Subsequent Burners in each Branch must be positioned sequentially.
Burners should be mounted with the Burner casting as far back in the Tube opening as possible. Ensure that little
or no Tube is in view through the viewing window.
Ensure that the End Vent Cap is oriented with the ¼” test hole at the 12 o’clock position and that it has been
secured to the end of each Branch with a #8 x 3/8” screw.
Ensure that Tubes are fully inserted in the Couplings and tightened with band clamp hardware at the 10 or 2
o’clock position. Tighten band clamps alternately to prevent buckling of the Coupling sleeve.
Ensure that each Branch has a Damper Coupling at the end of the Radiant length, as well as one at the Vacuum
Pump. If the system is symmetrical, one Damper along the Common Tailpipe may be used. Single Rate Systems
will use standard Manual Dampers while Modulating Rate Systems will use Motorized Dampers.
Ensure that Reflectors are properly overlapped and that every second overlap joint is screwed together, as
shown in Figure 9. The remaining joints are left loose. This will allow the Reflectors to ‘telescope’ with the thermal
expansion of the System.
Visually confirm that the Vacuum Pump’s impeller rotates in the same direction indicated by the arrow on the
pump scroll. To reverse the rotation, see instructions on the motor.
Ensure that EACH Flexible Gas Connector is of sufficient size for the desired Burner rate and is installed in a
smooth arc with no kinks.
Purge Gas Lines according to installation codes
Verify the Wiring and that the Electrical Power Supply is connected but remains turned OFF.
