ADJUSTING WATER TEMPERATURE

Remove the HM30 access panel. The water temperature dial is lo￿ cated at the lower left hand side of the HM30 control box. It is fac￿ tory set at 120_F (49_C). Water temperature setting may be raised by turning dial clockwise to the desired setting. Temperature set￿ tings are marked from 110_F (43_C) to 140_F (60_C). Each dash mark represents an increase of 10_F (5.6_C). Some local building codes limit the temperature of potable water to 120_F (49_C). Ask your Lennox dealer for information on highest allowable water temperatures and the use of anti￿scald and point￿of￿use water mix￿ ing valves. These valves help reduce the risk of scalding.

HM30 Tank Draining Procedure

It is recommended that 5 to 10 gallons of water from the HM30 tank be drained every six months to re￿ move any sediment. This may need to be done more often in areas of poor water condition.

1-Turn off power to unit and allow water temperature in HM30 tank to cool.

2-Remove HM30 access panel.

3-Connect hose to drain valve and route to open drain.

4-Open drain valve to allow water to flow.

5-After draining, close drain valve and disconnect hose. Replace access panel.

6-Fill tank with water and re￿apply power to the unit.

DO NOT re,apply power to a dry tank. The burner should never operate with an empty water tank. Irreparable damage to the HM30 unit may occur.

Lennox CompleteHeatTM COMBINATION HEATING SYSTEM specifications

Lennox International Inc., a leader in the heating, ventilation, and air conditioning (HVAC) industry, has consistently pushed the boundaries of innovative technology to enhance indoor comfort and energy efficiency. Among its standout products is the Lennox CompleteHeat™ combination heating system. Designed for residential applications, this system showcases advanced engineering and a range of features that provide homeowners with reliable and efficient heating solutions.

The Lennox CompleteHeat™ system is particularly notable for its dual functionality as both a heating and cooling unit. This versatility enables homeowners to use a single system for year-round climate control, eliminating the need for separate heating and cooling units. This not only saves on installation costs but also reduces the overall footprint within the home, allowing for more flexible use of space.

One of the key features of the CompleteHeat™ system is its use of advanced heat pump technology. This system operates efficiently by transferring heat rather than generating it. In moderate climates, it can extract warmth from the outside air and compress it to provide heating inside the home. During warmer months, the system can reverse this process to deliver cool air, contributing to an overall reduction in energy consumption.

The CompleteHeat™ system is equipped with variable-speed technology, which ensures optimal performance while minimizing energy use. This feature allows the system to adjust its output based on the heating demand, providing a consistent and comfortable indoor environment without the energy spikes associated with traditional fixed-speed systems. Additionally, the variable-speed blower improves air circulation, helping to maintain balanced temperatures throughout the home.

Another significant characteristic of the Lennox CompleteHeat™ system is its compatibility with smart home technology. Homeowners can easily integrate the system with smart thermostats and home automation systems, allowing for remote control and programming options. This connectivity not only enhances comfort but also promotes energy efficiency by enabling users to monitor and adjust settings according to their lifestyles.

Durability is also a hallmark of the CompleteHeat™ system. Designed with high-quality materials and components, it is built to withstand harsh weather conditions, ensuring long-lasting performance. Lennox offers an extensive warranty on the unit, providing peace of mind for homeowners.

In summary, the Lennox CompleteHeat™ combination heating system is an innovative solution that seamlessly integrates heating and cooling capabilities into one efficient unit. With its cutting-edge technology, variable-speed operation, smart home compatibility, and robust design, it represents the future of residential climate control. Homeowners looking to optimize their energy efficiency while maintaining comfort will find the CompleteHeat™ system to be an exceptional choice.
