C. LEVELING
In order for the condensate to properly flow out of the collection system, the appliance must be installed level. Failure to ensure the
appliance is installed level will result in improper appliance operation.
D. CLEARANCES FOR SERVICE ACCESS
See Figure 3 and Table 6 for recommended service clearances. If these minimum clearances are not provided, it may not be possible
to service the appliance without removing it from the space.
Space must be provided with combustion/ventilation air openings
correctly sized for all other appliances located in the same space as
the appliance. The appliance cover must be securely fastened to
prevent it from drawing air from the appliance room. This is particularly
important if the appliance is in a room with other appliances. Failure to
comply with the above could result in substantial property damage,
severe personal injury, or death.
