JJ_[Publications Litho U.S.A. ©1997 Lennox Industries Inc. / INTRODUCTION 7 The CompleteHeat™ Combination Heating System Congratulations on the purchase of your Lennox CompleteHeat system. Lennox takes pride in manufacturing high quality products that keep you comfortable while saving you energy and money. The CompleteHeat system is a high-efficiency combination water- and space-heating system. The system consists of an air module (AM30) and a heating module (HM30). The two units work together to provide warm air like a furnace and hot potable water like a hot water heater. The CompleteHeat system takes care of these needs while being up to 40% more efficient than standard furnaces and water heaters. This booklet explains how the CompleteHeat system operates, how to identify the unit model number, how to operate a typical thermostat and how to maintain the system for optimum performance. Keep this booklet and the warranty shipped with the CompleteHeat system for future reference. Thank you again for choosing Lennox. Page 1 / HOW THE CompleteHeat™ SYSTEM WORKS 7 The CompleteHeat system consists of a heating module (HM30) that produces hot water and an air handling module (AM30) that sends warmed air through the home’s duct system. The two modules may be installed together (close-coupled) or apart (remote). The system’s operation begins when cold potable water fills the water storage tank through the pipe at the top of the HM30 unit. When heat is needed to produce warm water or air, the HM30 control tells the combustion air blower to draw in outside air for use in combustion. After a short safety delay, a fuel mixture is sent into the burner where it is ignited by an electronic spark. Burning fuel moves through the stainless steel heat exchanger inside the water storage tank. The water surrounding the heat exchanger is heated until the water temperature reaches the desired setpoint on the water thermostat dial. Combustion products travel out of the heat exchanger, condensate water is drained, and exhaust gases are vented safely to the outdoors. Hot water is directed from the HM30 to faucets, shower heads, and appliances (such as the dishwasher and washing machine) through the plumbing located on top of the HM30 unit. When the room thermostat senses a need for heat, the AM30 water circulating pump draws hot water from the HM30 heating module and routes it through the AM30 space heating coil. The aluminium and copper coil absorbs heat from the water. The blower turns on, blowing air across the heated coil. Warmed air is sent through the air duct system into the home. Water circulates back to the HM30 unit to be reheated until the room temperature reaches the thermostat setting.

Make sure the area around both AM30 and HM30 units has adequate space according to the prescribed clearances. DO NOT store combustible materials such as newspapers, rags, mops, or flammable liquids such as gasoline, kerosene, paint thinner near this or any other heating appliance. A DANGER Vapors from flammable liquids will explode and catch fire causing death or severe burns. FOR YOUR SAFETY - Do not store or use gasoline or other flammable, combustible, or corrosive vapors and liquids in the vicinity of this appliance. Keepflammableproducts: Vapors: 1. farawayfromheater, 1. cannotbeseen, 2. inapprovedcontainers, 2. areheavierthanair, 3. tightlyclosed,and 3. goalongwayonthefloorand 4. out of childrens reach. 4. can be carried from other rooms to the heater by air currents. A DANGER m'iiïi. HOT' Water temperature over 125°F can cause severe burns instantly or death from scalds. Children, disabled and elderly are at high risk of being scalded. See the Adjusting Water Temperature section in this manual before setting temperature at heat module (HM30 unit). Feel water before bathing or showering. Temperature limiting valves are available and are recommended for all applications. Page 3 / TO START THE CompleteHeat SYSTEM 7 A WARNING MAIN MANUAL SHUT-OFF VALVE If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or loss of life. MAIN MANUAL SHUT-OFF VALVE SHOWN IN OFF POSITION 1 — STOP! Read the safety information at the beginning of this section. 2— Set both room thermostat and water temperature dial to lowest settings. 3—Turn off all electrical power to the CompleteHeat system (AM30 & HM30 unit). Ask your dealer to identify the disconnect switch or circuit breaker. 4— The HM30 unit is equipped with an ignition device which automatically lights the burner. Do not try to light the burner by hand. 5—Turn knob on main manual shut-off valve 90° counterclockwise to ON. Do not force. 6— T...
