59CU5A: Installation, Start-up, Operating and Service and Maintenance Instructions

Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.

load estimates and select the furnace. Excessive oversizing of the

furnace may cause the furnace and/or vent to fail prematurely, customer

discomfort and/or vent freezing.
Failure to follow these guidelines is considered faulty installation and/or

misapplication of the furnace; and resulting failure, damage, or repairs

may impact warranty coverage.
For accessory installation details, refer to the applicable instruction

literature.

NOTE:

Remove all shipping materials, loose parts bags, and literature

before operating the furnace, see

Table 2

. The Ultra Low NOx

condensing furnaces also contain an additional parts bag for the

condensate trap, see Condensate Trap section.
