Installation Guide for Comfort Pack (CPG) Units

 

1. National Comfort Products warrants to its customers that its product shall be free from defects in material and workmanship 

under normal use and regular service and maintenance as follows:

 

HEAT ExCHANGERS (Gas units only): for ten years from the date of original installation.   

  

ALL OTHER PARTS:  For all other parts except the Heat Exchanger, for five years from the date of original installation.   

 

Customer must register the product within 60 days of purchase. If Customer cannot adequately document date of installation, 

then, for purposes of determining the warranty period, the date of installation shall be 60 days from the date of purchase.  

 

2.   This warranty does not extend to any damages or losses due to misuse, accident, abuse, neglect, normal wear and tear, 

negligence (other than National Comfort’s), unauthorized modification or alteration; use beyond rated capacity; unsuitable power 

sources or environmental conditions; improper installation, repair, handling, maintenance or application; damage as a result of fire, 

wind, floods, lightning, or corrosive conditions; or any other cause not the fault of National Comfort.  By way of example and without 

limitation, the following do not constitute a defect in workmanship and materials and are not covered by this warranty: slugging of 

liquid refrigerant or oil, unstable line voltage, lightning, operating without proper lubrication, and operating without factory provided 

safeties.  Any installation that impairs or impedes air flow negatively impacts performance and causes premature equipment failure 

that voids this warranty.  For example, installation behind a brick façade or the addition of a brick pattern façade, i.e. pigeon holes 

impedes air flow and shall void this warranty. No warranty will apply if the input section exceeds the rated input as indicated on the 

nameplate by more than 5%, or if the heat section in the judgement of the manufacture has been subject to misuse, negligence, 

accident,  corrosive  atmospheres,  atmospheres  contacting  any  contaminant  (silicone,  aluminum  oxide,  etc.),  excessive  thermal 

shock, physical damage, impact, abrasion, unauthorized alterations, or operation contrary to the manufacture’s printed instructions, 

or if the serial number has been altered, defaced, or removed.

 

3.
