Description and Purpose
IMPORTANT NOTE
The purpose of this manual is to act as an instal- lation guide only for the LIFEBREATH Clean Air Furnace. 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 Clean Air Furnace. Be sure to consult the proper authori- ties.
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 appliance 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 commission- ing of these systems are critical if these advan- tages 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 residential 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 comply with recognized Residential Air System Design methods. This manual provides work- sheets to be used for the purpose of sizing resi- dential water heaters and the combo furnace.
The LIFEBREATH Clean Air Furnace is a volume ventilator system and is not intended to replace a fully ducted Heat Recovery Ventilation (HRV) sys- tem. Independent exhaust fans should be used for bathrooms and kitchen range hoods.
