Page 24: Typical Suspension Methods
The appliance should be located with respect to building construction and other equipment to permit access to the appliance for servicing etc. Space-Ray recommends that the body sections be suspended using chains with turnbuckles. This will allow slight adjustments after assembly and heater expansion/ contraction during operation. -
Page 25: Burner Box Support Details
Fig. 18 Fig. 18 Fig. 18 Fig. 18 9.1) BURNER BOX SUPPORT DETAILS The burner box must be supported with a welded chain after overall heater suspension is complete.
