## • Questions and Request fo.r Comments:

- Is there a practical size limit for a packaged boiler?

- Should there be a size limit? And if yes, at what input? » Gas-fired: As specified by ANSI Z21.13 ? »**Oil~fired:** Same .as gas-fired, or different value?

- Should the test procedure be limited to space heating boilers?

### - If so, shouldjacket loss be excludedfor indoor installation?

### • Labeling rule must be prescribed within 12 months of prescribing test procedures. The date for displaying the labels is 12 months from the rule prescription date. • EPCA §344 (b): label must show the energy efficiency. DOE may require estimated operating costs and energy use onlabel. • EPCA §344(c): DOE can prescribe additional requirements likely to assist purchasers in making purchasing decisions. • EPCA §344 (e): provides additional labeling requirements and authority. • EPCA §344 

### (f): no labeling rules unless certain conditions are met.

# LABELING Labeling ofMixed Components 

## Some covered commercial equipment is comprised 

## of separate components, often furnished

## by different manufacturers. 

## For residential appliances, for split system condenserevaporator coil systems, the required labels contain energy efficiency ratings which are either

- 

### (1)

### the energy efficiency rating ofthe condenser-evaporatorcoil combinationthat is the particular manufacturer's most commonly sold combination forthat condenser model; or

- 

### (2)the energy efficiency rating ofthe actual condenser-evaporator coil combination comprisingthe system to 

### which the label is to 

### be attached.
