Page 11: Typical Suspension Methods
6. Heaters must not be supported by gas or electric supply lines and must be suspended from a permanent structure with adequate load capacity. Mestek recommends that the tube sections be suspended using chains with turnbuckles. This will allow slight adjustments after assembly and heater expansion/ contraction during operation.
Page 12: Heater Assembly
10.0) HEATER ASSEMBLY During field assembly of the heater, the recommended procedure is as follows: 1. Put the suspension in place (according to Section 7.0) using proper suspension method (see Section 9.0).

Place the flanges of the control end reflector flush with the end of the first reflector. Secure by sliding speed clips onto reflector edges.
Page 14 7. Slip the plastic vacuum air tube over the 1/4” O.D. aluminum tube end of the draft inducer and the air switch probe in the control box. The air tube should be shortened to prevent a downward sag which could allow condensation build-up in the tube.
