Description and Purpose
IMPORTANT NOTE
The purpose of this manual is to act as an instal- lation guide only for the LIFEBREATH Air Handler. Manufacturers' instructions for other components, such as the waterheater/boiler, must be followed.
All national and local code requirements must be met when installing a LIFEBREATH Air Handler. Be sure to consult the proper authorities.
Note: Temperatures greater than 130 °F (54°C) pose a serious risk of scalding individuals running domestic hot water for potable use.
This appliance complies with IAS Canada Inc. Requirement
All piping and components connected to this appli- ance shall be suitable for use with potable water.
Toxic chemicals, such as used for boiler treat- ment, shall not be introduced into the potable water heater system.
When using this system, and water for space heating, is required to be at a higher temperature than for other uses, an
Combining two or more end uses such as space heating and the heating of domestic hot water in a
single system has the potential to increase effi- ciency and reduce overall capital costs. However, the proper design, installation, and commissioning of these systems is critical if these advantages are to be realized.
This manual provides a guideline of good engi- neering practice in the design, installation and commissioning of Integrated Combo Systems. The guidelines in the manual are designed for res- idential forced warm air Integrated Combo Systems which utilize domestic water heaters or boilers and the LIFEBREATH furnace. Heating and cooling loads shall be calculated in accor- dance with recognized Residential Heat Loss and Heat
Gain Calculation methods. Duct design shall com- ply with recognized Residential Air System Design methods. This manual provides worksheets to be used for the purpose of sizing residential water heaters and the combo furnace.
