INSTALLATION—CONTINUED
Heater Suspension
⚠ WARNING ⚠
• Before suspending the heater, check the supporting structure to be used to verify that it has
sufficient load-carrying capacity to support the weight (refer to Weights section) of the unit.
• The heater must be level for proper operation. DO NOT place or add additional weight to a
suspended heater.
⚠ CAUTION ⚠
• Before lifting the heater, verify that any screws used for holding shipping brackets were re-
installed in the cabinet.
• Before lifting the heater, any unused suspension points MUST be plugged.
• When the heater is lifted for suspension, support the bottom of the heater with plywood or other
appropriately placed material. If the bottom is not supported, damage could occur.
NOTE: Four-point suspension is recommended. Two-point suspension is permitted only on unit
sizes 055–110 when installed without a downturn nozzle.
• A 3/8-16 threaded nut retainer is located at each suspension point. The heater may be suspended using either
3/8-inch threaded rods or a hanger kit option package.
• Using capscrews and washers, seal any unused holes in the top of the heater after installing the hanging hardware
(see Figure 7).
