Page 11: Installation Procedure
INSTALLATION PROCEDURE WARNING: 1. The best results are obtained when the detector is aimed so that the detector’s line of sight intersects the burner center at a slight angle (e.g. 5 degrees) and sees a maximum of the primary combustion zone, as shown in Figure 3. -

Page 16: Section 3 Commissioning
SECTION 3 COMMISSIONING Before commissioning, complete all of the installation instructions. INITIAL CHECKOUT 1. Verify the operation of the detector head as follows: a) Remove mounted IDD detector head. b) Connect it to the four-conductor cable. c) Place a light source 1 to 4 feet from the surface of the detector. Use a Tungsten light source for IR detector heads and a UV light source for the IDD-Ultra. -

Page 19: Section 6 Maintenance
The IDD detector head is a non-repairable device and requires no maintenance other than periodically cleaning the cell surface. The appropriate cleaning schedule is determined by the quality and cleanliness of the cooling-/seal-air source. Forney recommends the use of a non-oily cleaning solution and a soft lint-free cloth for lens cleaning. -
