Dryer-Ell Model LT-90 Installation Instructions

Assembly

2. Mate the two parts so that the screw holes line up.
3. Secure the flanges with five sheet metal screws.
4. Bend the tabs down and tape the joints along the flange.

1. Model LT90 should be measured as 1-1/2" feet against the total allowable duct length.  See engineering paperwork link below and 2009 IMC Table 504.6.4.1 and IRC Table M1502.4.4.1 for 10" radius fittings.
2. Arrow indicates airflow direction from dryer and provides for proper male and female connections.
